Results of the tension-free vaginal tape procedure for the treatment of type II stress urinary incontinence at a minimum followup of 1 year

PURPOSE: We evaluated the safety and efficacy of the tension-free vaginal tape procedure for treating type II stress urinary incontinence in females. MATERIALS AND METHODS: Between April 1998 and April 1999, 62 women 28 to 86 years old (mean age 62.8) were treated consecutively for stress urinary incontinence with the tension-free vaginal tape procedure. Preoperative evaluation included history, physical examination and multichannel video urodynamics. All patients had type II stress urinary incontinence, none had preoperative detrusor instability or significant pelvic prolapse and in 16 previous surgery for stress incontinence had failed. RESULTS: All patients were followed at least 12 months after the procedure (median 16.2). A total of 42 and 20 women received spinal and local anesthesia, respectively. We noted 6 bladder perforations, including 5 in patients with a history of surgery for stress urinary incontinence. Blood loss was less than 200 cc in all cases. We observed no prolonged postoperative pain, infection or sling rejection. Post-void residual urine was less than 100 cc the day after surgery in 59 cases. Only 3 patients self-catheterized a maximum of 4 days. At followup 54 women (87.1%) were cured of stress urinary incontinence, 6 were improved (9.6%) and 2 had failure (3. 3%), while 4 (6.4%) had new onset detrusor instability without evidence of bladder outlet obstruction. CONCLUSIONS: The tension-free vaginal tape procedure appears to be a minimally invasive, safe and effective treatment for type II stress urinary incontinence. A history of surgery for stress incontinence seems to be a risk factor for bladder perforation.     

A prospective trial comparing tension-free vaginal tape and transobturator vaginal tape inside-out for the surgical treatment of female stress urinary incontinence: 1-year followup

PURPOSE: We prospectively compared the efficacy and safety of tension-free vaginal tape and transobturator vaginal tape inside-out for female stress urinary incontinence. MATERIALS AND METHODS: A total of 120 women with stress urinary incontinence were alternately assigned to the tension-free vaginal tape group (60) or the transobturator vaginal tape inside-out group (60). Preoperative evaluation included urodynamic study and a Korean version of the incontinence quality of life questionnaire. One year after operation the surgical result, patient satisfaction, incontinence quality of life questionnaire, long-term complications and uroflowmetry were evaluated in the 2 groups. RESULTS: Patient characteristics were comparable in the 2 groups. Mean +/- SD operative time was significantly shorter in the transobturator vaginal tape inside-out vs the tension-free vaginal tape group (11 +/- 1.4 vs 15 +/- 1.8 minutes). In the transobturator vaginal tape inside-out and the tension-free vaginal tape groups the rates of cure (86.8% and 86.8%), improvement (6.6% and 8.2%) and failure (6.6% and 5.0%, respectively) were similar. Incontinence quality of life questionnaire parameters 1 year after surgery were improved significantly in each group and there was no difference between the 2 groups (p <0.001 and >0.05, respectively). There was no long-term complication in either group. Preoperative urge incontinence resolved in 80% of the tension-free vaginal tape group and in 100% of the transobturator vaginal tape inside-out group. De novo urgency developed in 4 patients (6.6%) in the transobturator vaginal tape inside-out group. CONCLUSIONS: The tension-free vaginal tape and transobturator vaginal tape inside-out procedures were minimally invasive and similar in operation related morbidity. Transobturator vaginal tape inside-out appeared to be as effective and safe as tension-free vaginal tape for the surgical treatment of stress urinary incontinence in women at 1-year followup.     

Tension-free vaginal tape procedure for the treatment of mixed urinary incontinence: significance of maximal urethral closure pressure

PURPOSE: We investigated factors predicting persistent urge incontinence after the tension-free vaginal tape procedure in patients with mixed urinary incontinence. MATERIALS AND METHODS: Between March 1999 and May 2003 female patients with complaints of urinary incontinence were evaluated according to our protocol. After the tension-free vaginal tape procedure patients were followed at 1, 6 and 12 months, and yearly thereafter. A total of 274 women (stress urinary incontinence in 201 and mixed urinary incontinence in 73) with followup at least greater than 6 months were included in the study. The cure of stress induced incontinence after the procedure was defined as an absent subjective complaint of leakage and objective leakage on stress testing. All other cases were considered failures. RESULTS: There was no significant difference in the cure rate for stress induced incontinence between patients with stress and mixed urinary incontinence. However, 12 of 73 patients (16.4%) with mixed urinary incontinence had persistent urge incontinence. Thus, the overall cure rate was significantly higher in the stress incontinence group than in the mixed incontinence group (95.5% vs 78.1%, p <0.001). On multivariate analysis maximal urethral closure pressure was associated with a 0.9-fold risk of persistent urge incontinence after the procedure in patients with mixed urinary incontinence (OR 0.94, 95% CI 0.88 to 0.99, p = 0.030). CONCLUSIONS: Our findings suggest that low maximal urethral closure pressure may be associated with persistent urge incontinence after the tension-free vaginal tape procedure in patients with mixed urinary incontinence.     

Tension-free vaginal tape and associated procedures: a case control study

OBJECTIVES: We compare objective and subjective cure rates after tension-free vaginal tape procedures performed alone or in conjunction with vaginal procedures. METHODS: One hundred eighty-six women underwent a tension-free vaginal tape procedure for stress or mixed urinary incontinence. One hundred women treated with tension-free vaginal tape alone (group 1) were compared with 40 women treated with tension-free vaginal tape and concomitant vaginal hysterectomy (group 2), and 46 patients treated with tension-free vaginal tape and pelvic floor reconstruction (group 3). Patient outcomes, surgical difficulties and complications are reported. Postoperative voiding diaries, standing stress-test results, and patient satisfaction were compared. RESULTS: There were no significant differences among the three groups in terms of age, menopausal status, BMI, previous incontinence surgery, or the type and degree of incontinence. Parity was significantly higher in the group treated with tension-free vaginal tape and pelvic floor reconstruction ( p=0.04 ). The overall perioperative complication rate was 15.6%. Women treated with tension-free vaginal tape and hysterectomy (group 2), and those treated with tension-free vaginal tape and pelvic floor reconstruction (group 3) had a significantly higher incidence of bladder injury (17.9% and 13%, respectively, versus 5% in group 1; p=0.05 ). Estimated blood loss and the frequencies of postoperative urgency and voiding disorders did differ significantly between women treated with tension-free vaginal tape alone and those who underwent associated procedures. The mean follow-up time was 24.5+/-2.6 months. No difference in the objective cure rate was found between the tension-free vaginal tape group and the other two groups (93% versus 97.5% and 91.1%; p=0.3 ). No difference in the subjective cure rate was found between the tension-free vaginal tape group and the groups undergoing associated procedures (72% versus 72.5% and 68.8%; p=0.4). CONCLUSION: Pelvic floor defects, benign uterine disorders and stress urinary incontinence can be safely treated with tension-free vaginal tape and vaginal procedures during the same surgical procedure.     

Surgical intervention for complications of tension-free vaginal tape procedure

PURPOSE: The tension-free vaginal tape procedure has become a state of the art operation for female stress urinary incontinence. Cases of complications requiring surgical revision are reported to be rare. We report on 6 patients with complications necessitating surgery. MATERIALS AND METHODS: Six patients who previously underwent the tension-free vaginal tape procedure required surgical management of complications, including intravesical polypropylene mesh tape with incrustation and chronic urinary tract infection in 2, vaginal mucosal mesh erosion of the vaginal incision in 1 and permanent urinary retention in 3. RESULTS: The intravesical tapes were resected via a suprapubic approach. In the case of disturbed wound healing the periurethral part of the tape was resected transvaginally. A patient in urinary retention underwent resection of the periurethral sling, while in the other 2 the tapes were transected transvaginally. Two patients in whom incontinence recurred were successfully treated with a repeat tension-free vaginal tape procedure during followup. CONCLUSIONS: Complications of the tension-free vaginal tape procedure that require surgical intervention are rare. The surgeon must be aware that this operation may lead to an additional surgical procedure, significantly increasing morbidity.     

Determinants of patient dissatisfaction after a tension-free vaginal tape procedure for urinary incontinence

PURPOSE: We identified the determinants of patient satisfaction after a tension-free vaginal tape procedure. MATERIALS AND METHODS: We retrospectively analyzed the records of 187 consecutive women with genuine stress (133) and mixed (54) incontinence. The objective cure rate was determined by clinical and urodynamic examination, and the subjective cure rate was assessed by a visual analog scale and the Contilife questionnaire. RESULTS: Mean followup was 27 months (range 6 to 34). The overall complication rate was 35.3%. The major perioperative and postoperative complications were bladder injury in 9.6% of cases, urinary retention in 6.4%, difficult voiding in 10.7% and new onset urge symptoms in 21.3%. The overall objective and subjective cure rates were 90.4% and 70.6%, respectively. The mean preoperative and postoperative visual analog scale score plus or minus standard deviation was 6.2 +/- 2.4 and 0.9 +/- 2.2, respectively (p = 0.0001). The subjective cure rate was significantly lower in women who underwent the procedure under general or spinal anesthesia than in those who received local anesthesia (p = 0.01). This difference was related to the rate of new onset urge symptoms. The mean postoperative visual analog scale score in women with and without new onset urge symptoms was 2.2 +/- 3.2 and 0.2 +/- 0.7, respectively (p = 0.0001). No difference in the subjective cure rate was detected according to patient age, menopausal status, previous incontinence surgery, the body mass index, additional procedures associated with tension-free vaginal tape surgery or the Ingelman-Sundberg classification. CONCLUSION: These results confirm that the tension-free vaginal tape procedure is associated with a high objective but lower subjective cure rate. The procedure performed using local anesthesia was associated with a lower incidence of difficult voiding and new onset urge symptoms.     

Tension-free vaginal tape procedure for the treatment of female stress urinary incontinence: long-term results

PURPOSE: The tension-free transvaginal tape (TVT) procedure has apparently become the most popular technique for genuine stress urinary incontinence (GSUI). Long-term followup data on the outcome of the procedure are sparse. We evaluated the long-term results of TVT for treating women with GSUI. MATERIALS AND METHODS: We performed a retrospective analysis of the records of 55 patients 37 to 83 years old (mean age 63.4) with GSUI, for which they underwent the TVT procedure at our department as of December 1999. RESULTS: Of the 52 patients who were followed a mean of 55 months (range 48 to 65) 41 (78.9%) were dry. There were 4 intraoperative complication (7.3%), including bladder injury in 3 patients and urethral injury in 1. None required surgical re-intervention. Urgency was reported in 6 women (11.5%). There were 5 postoperative tape related complications (9.6%), consisting of bladder erosion in 1 woman, vaginal erosion in 2 and an obstructed urethra in 2. Four of these 5 women underwent corrective surgery, after which all remained dry. CONCLUSIONS: TVT is a safe and effective procedure for female stress urinary incontinence with an enduring, high success rate. There is a significant rate of intraoperative complications, which do not cause further problems when identified and treated during surgery. One must be alert to the significant rate of postoperative complications that usually require repeat surgery, which is relatively simple and causes practically no long-term morbidity. It also does not influence the continence rate in most cases.     

Experience of tension-free vaginal tape for the treatment of stress incontinence in females with neuropathic bladders

STUDY DESIGN: Retrospective. OBJECTIVE: To evaluate the safety and efficacy of the tension-free vaginal tape (TVT) for the treatment of stress incontinence in females with neuropathic bladders. SETTING: London Spinal Injuries Unit, Stanmore & Institute of Urology, London, UK. METHODS: Twelve women (mean age 53.3 years; range 41-80 years) with neuropathic bladder dysfunction and stress urinary incontinence were treated with tension-free vaginal tape (TVT) between November 1997 and December 2000. The group consisted of women with: (i) traumatic spinal cord injuries (n=3); (ii) post lumbar spinal surgery (n=6); (iii) spinal stenosis (n=3). Four of the 12 patients had previously failed surgery for stress incontinence. All patients underwent pre- and post-TVT evaluation with video-urodynamic studies. RESULTS: Mean follow-up was 27.1 months (range 17-54 months). Three patients were voiding spontaneously (stress voiding) before surgery and continued to do so post-operatively. The remaining 9 were performing clean intermittent self-catheterisation before the insertion of TVT and continued to do so after the surgery. At follow up 10 patients (83.3%) were dry. The procedure failed in one patient and the other complained of mild leakage, but she reported a decrease in the number of pads used. One patient developed detrusor hyperreflexia on post-operative video-urodynamics but there was no evidence of stress incontinence. One patient had a bladder perforation on insertion of TVT, managed successfully with extended use of a urethral catheter post-operatively. Three patients developed post-operative urinary tract infection successfully treated with oral antibiotics. CONCLUSIONS: Tension-free vaginal tape insertion is minimally invasive, safe and effective for the treatment of stress incontinence in females with bladder neuropathy with intrinsic sphincter deficiency. Previous surgery for incontinence did not affect post-operative complications or outcome.     

Transvaginal tape lysis for urinary obstruction after tension-free vaginal tape placement

PURPOSE: We examine the outcome of tape lysis in subjects with obstructive urinary retention after initial tension-free vaginal tape placement. MATERIALS AND METHODS: Charts from 109 consecutive subjects who underwent tension-free vaginal tape placement from 1998 to 2001 were retrospectively reviewed. Of the subjects 78 (72%) consented to participation and completion of a questionnaire. All subjects underwent a routine preoperative evaluation before surgery and followup was implemented through 2002. Tape lysis using a standard technique was performed in 5 patients with documented obstructive urinary retention. Subjective assessment by the validated Bristol Lower Urinary Tract Symptoms questionnaire and a postoperative survey characterized perceptions of incontinence, results of initial tension-free vaginal tape placement and outcome of subsequent tape lysis. RESULTS: The objective incontinence cure rate was 89%. Of the 78 patients 17 (22%) and 21 (27%) experienced transience in either dysuria or incomplete bladder emptying, respectively. Transection for obstructive urinary retention was successfully accomplished in 5 subjects with 4 (80%) remaining continent. CONCLUSIONS: Tape lysis is simple and effective for relieving obstruction, and is not associated with a high rate of recurrent stress urinary incontinence.     

The tension-free vaginal tape procedure for female urinary incontinence without preoperative urodynamic evaluation

BACKGROUND: We evaluated the short-term outcomes of the tension-free vaginal tape (TVT) technique for female urinary incontinence, when the diagnosis was based on incontinence symptoms and pelvic examination including cough stress test or transperineal ultrasonography or both, but without preoperative urodynamic verification. STUDY DESIGN: Tension-free vaginal tape was performed on 191 patients under local (82%) or spinal (18%) anesthesia. One hundred twenty-seven women (66%) had stress urinary incontinence and 64 (34%) had mixed incontinence. Fifty-eight percent had undergone previous surgery; 21% for incontinence. Thirty-four women underwent concomitant surgery. The age range was from 32 to 84 years (mean 60) and parity from 0 to 8 (mean 2). Seventy-four (39%) had concomitant chronic illnesses. The diagnosis of incontinence was based on specific questionnaires and physical examinations. Urogynecological ultrasonography was performed on patients with mixed incontinence. The mean followup was 17 months. RESULTS: The mean operative time was 27 min (16 to 63), the mean hospital stay was 2 days (1 to 10). Intraoperative complications were: bladder perforation in five patients (2.6%), hematoma in five patients (2.6%), heavy bleeding (400 mL) in one patient, and persistent retention in four patients (2.2%). Altogether, 164 of 187 patients (87.7%) were completely cured, and 23 patients experienced no improvement. Six patients (4.8%) developed de novo urge incontinence, 60% had less urge incontinence. The cure rates were: 97% among stress urinary incontinence patients versus 69% among mixed incontinence patients (p = 0.001); TVT alone, 88% versus in combination with other surgery 85% (p = 0.576); TVT under local anesthesia, 88% versus under spinal anesthesia 88%; TVT with recurrent incontinence, 85% versus primary incontinence 89% (p = 0.583); and in patients with concomitant illnesses, 82% versus healthy 91% (p = 0.076). CONCLUSIONS: Tension-free vaginal tape can be used to treat patients with primary or recurrent stress or mixed incontinence with or without concomitant surgery under local or spinal anesthesia. But the success rate is considerably lower in patients in whom TVT is performed for mixed incontinence.     

Sexual function after tension-free vaginal tape (TVT) for stress incontinence: results of a mailed questionnaire

In a retrospective study we evaluated sexual function after tension-free vaginal tape (TVT) placement for urinary stress incontinence based on responses to a mailed questionnaire at least 3 months after the operation, to a maximum of 1 year. From 1999 to 2002, a sexual function questionnaire was mailed to 128 women (and their partners) who had undergone a TVT procedure for genuine urinary stress incontinence, without pelvic organ prolapse or detrusor instability. The questionnaire was returned by 96 women (75%), 69 (72%) of whom reported being sexually active. Mean frequency of intercourse did not change. Overall, 26% described improved intercourse compared to before the operation. Only one patient described worsening of intercourse after the TVT operation because of an increase in her incontinence. Overall, in this study the technique of tension-free vaginal tape as such seems to have no negative impact on sexual function. However, because of its successful outcome on incontinence, it has a positive overall effect on sexual function. The possible causes of postoperative partner discomfort require further investigation.Abbreviations AVWS Anterior vaginal wall suspension - SUI Stress urinary incontinence - TVT Tension-free vaginal tape This study was supported by the Pelvic Floor & Sexuality research group Leiden. Editorial Comment: The impact of urogynecologic surgery on sexual function is unclear. For those who are incontinent with intercourse, cure of incontinence may improve sexual activity at the price of potential damage to the vaginal anatomy. In this study sexual function following the TVT procedure was evaluated. The authors report that sexual frequency was overall unchanged, and many patients felt that intercourse improved. It appears that much of this improvement is probably related to cure of the incontinence rather than any specific features of the TVT. Although the study is flawed by its retrospective design and a long interval between the procedure and the questionnaire, the results overall are reassuring.     

Tension-free vaginal tape for surgical treatment of stress urinary incontinence: Two years follow-up

BACKGROUND: The objective was to study prospectively the effectiveness of tension-free vaginal tape as an ambulatory and minimal invasive operation for the treatment of female stress incontinence. METHODS: The tension-free vaginal tape procedure was performed in 25 patients with genuine stress incontinence and they were followed for a 2-year period. All patients were diagnosed with urodynamics to have genuine stress incontinence. Pad tests, cough stress test and quality-of-life assessments were carried out in all patients, both preoperatively and postoperatively. The majority of the women were discharged the morning after the surgical procedure. RESULTS: Twenty of 25 (80%) patients were found to be cured 2 years after the operation. The vaginal tape was spontaneously dropped out from the vagina in one patient 2 weeks after the procedure. We did not see such a complication in previous studies. CONCLUSION: We conclude that the tension-free vaginal tape procedure is both a safe and effective method to cure genuine female stress incontinence. Furthermore, it can be performed as an ambulatory procedure under local anesthesia with a short operative time.     

Tension-free vaginal tape (TVT) for the treatment of occult stress urinary incontinence in women undergoing prolapse repair: a prospective study of 100 consecutive cases

AIMS: Clinically continent women with genitourinary prolapse and occult stress urinary incontinence (SUI) are considered to be at high risk of developing symptomatic SUI once the prolapse is repaired. We studied the efficacy and safety of tension-free vaginal tape (TVT) procedure in preventing postoperative SUI in these women. METHODS: One hundred consecutive women (mean age 66.7 +/- 9.9 years) with significant genitourinary prolapse and occult SUI were prospectively enrolled. Preoperatively, none of the women complained of SUI. However, all had urodynamically-confirmed occult SUI, revealed by repositioning of the prolapse. Surgical intervention was comprised of transvaginal prolapse repair and prophylactic TVT procedure. Main outcome end points included operative morbidity, postoperative SUI, persistent or de novo urge incontinence, and voiding dysfunction. RESULTS: The mean follow-up period was 27 months (range: 12-52 months). There was only one case of technique-related bladder perforation with no adverse outcome. Two other patients had postoperative urinary retention necessitating catheterization for more than 7 days, none of whom required any surgical intervention. Vaginal erosion of the tape was diagnosed in three patients, all of whom were successfully treated by excision of the eroded tape. Two (2%) patients developed urodynamically-confirmed SUI within 1 year postoperatively. However, postoperative urodynamics revealed asymptomatic sphincteric incontinence in 15 (15%) other patients. Thirteen (72%) of 18 patients with preoperative urge incontinence had postoperative persistent urge incontinence. De novo urge incontinence developed postoperatively in 8 (8%) patients. CONCLUSIONS: TVT procedure is effective and safe in patients with occult SUI undergoing prolapse repair. Long-term durability of this procedure is yet to be established.     

Vaginal delivery after tension-free vaginal tape procedure

To treat genuine stress urinary incontinence, the surgical technique of choice at present is suburethral tension-free vaginal tape (TVT) procedure. Because of its good results and low morbidity, TVT is now offered to younger women still of childbearing age. We describe a patient who delivered vaginally 2 years after undergoing a retropubic TVT procedure. The woman remained continent throughout her pregnancy and at 6 months postpartum, with normal urodynamic parameters.     

Preoperative maximal flow rate may be a predictive factor for the outcome of tension-free vaginal tape procedure for stress urinary incontinence

This study examined factors potentially predicting on the outcome of the tension-free vaginal tape procedure for stress urinary incontinence. A total of 60 women (aged 35–71 years, mean 57) with at least follow-up of 2 years were included in the study. The tension-free vaginal tape procedure was performed under local anesthesia except in two patients. At the latest follow-up 50 (83.3%) were cured of stress urinary incontinence. Two patients had new-onset urge symptoms without urge incontinence episodes. Multivariate regression analysis showed maximal flow rate to be associated with 0.9-fold risk of the failure; no other parameters had statistical significance. Our results confirm the feasibility and safety of the tension-free vaginal tape procedure and demonstrate that preoperative low maximal flow rate may be associated with the failure of the tension-free vaginal tape procedure.Editorial comment: The authors in this study evaluated the outcome of the tension-free vaginal tape based on subjective and objective parameters and evaluated possible predictors of failure associated with this procedure using univariate and multivariate logistic regression analysis. Their rates of cure, improvement, and failure of, respectively, 83.3%, 11.7%, and 5.0% are comparable to those of other studies. Of all the clinical parameters evaluated they found only one statistically significant variable associated with outcome. Higher preoperative maximal flow rate was associated with a decreased likelihood of failure. The authors propose several hypotheses to explain for this finding, including poor detrusor contractility, low urethral mobility during the voiding phase, and low urethral pressure. To provide clinical usefulness one needs to determine at what cutoff does maximum flow rate become a risk factor for failure of the TVT.     

The Rosti sling: a new, minimally invasive, tension-free technique for the surgical treatment of female urinary incontinence-the first 217 patients

PURPOSE: We evaluated the outcome of a new, innovative, inexpensive tension-free technique, the Rosti sling (RS), for female urinary incontinence. MATERIALS AND METHODS: RS was performed in 217 patients under local (45%), spinal (52%) or general (3%) anesthesia. A 1.5 x 33 cm strip of polypropylene mesh was inserted under the mid urethra from above through small suprapubic stabs down and out through a 1.5 cm midline vaginal incision using the Stamey needle. Of the women 76% had stress urinary incontinence and 24% had mixed incontinence. Patient age was 24 to 90 years (mean 56) and parity was 0 to 6 (mean 2). The diagnosis of incontinence was based on history and physical examinations with a cough stress test. Mean followup was 23 months. RESULTS: Mean operative time was 25 minutes (range 15 to 45) and mean hospital stay was 3 days (range 1 to 12). Perioperative complications were bladder and urethral perforations in 2 and 1 cases, respectively (1.4%), and hematoma in 3 (1.4%). There was postoperative retention with a variable duration in 49 patients (23%), of whom 41 underwent Hegar dilation. Altogether 186 of 215 patients (86.5%) were cured of incontinence. Two patients were lost to followup and 14 (16.3%) had de novo urge incontinence. The cure rates were 87% for stress urinary incontinence and 91% for mixed incontinence. The cure rate in patients treated under local and spinal anesthesia were 82% and 91%, respectively (p = 0.1084). The rates for RS with recurrent vs primary incontinence were 84% vs 87% (p = 0.5800) and for RS with vs without Hegar dilation 80% vs 88% (p = 0.2094). CONCLUSIONS: The technique described is simple, safe and inexpensive. The cure rates are comparable to those of tension-free vaginal tape. However, because of the relatively high rate of postoperative voiding difficulties compared to tension-free vaginal tape, this technique can be criticized. To avoid these problems special attention should be focused on applying the mesh without tension and with precision.     

Factors predictive of urinary retention after a tension-free vaginal tape procedure for female stress urinary incontinence

PURPOSE: We performed this study to evaluate factors related to urinary retention after a tension-free vaginal tape (TVT) procedure for female stress urinary incontinence. MATERIALS AND METHODS: We retrospectively analyzed the records of 375 women with a followup of at least 6 months from among patients who underwent the TVT procedure between March 1999 and May 2002 at our institution. We analyzed multiple parameters, including patient characteristics, symptoms and urodynamic studies, using univariate and multivariate regression analyses with respect to postoperative urinary retention, as defined by the need for intermittent catheterization for at least 3 days after the procedure. All patients in the nonretention (343) and retention (32) groups answered a global satisfaction question. RESULTS: In answer to a global satisfaction question 338 of the 375 patients (90.1%) favored the procedure. Univariate analysis demonstrated that patient mean age, parity, peak urinary flow and a history of hysterectomy predicted urinary retention. However, on multivariate analyses the peak urinary flow rate was the only significant independent predictive factor (p = 0.007). While 28 patients (87.5%) in the retention group regained normal voiding without a specific procedure, 4 required tape release or cutting within 3 month of surgery. The global satisfaction question showed a significant difference between the nonretention and retention groups (91.5% vs 75% satisfaction, p = 0.03). CONCLUSIONS: An accurate measurement of the peak urinary flow rate could predict women at risk for postoperative urinary retention that compromises global satisfaction after the highly curative TVT procedure.     

Tension-free vaginal tape surgery for stress urinary incontinencne: A prospective multicentered study in Japan

AIM: To report the prospective multicentered study of the tension-free vaginal tape (TVT) procedure for stress urinary incontinence. METHODS: One hundred and fifty-one women with stress urinary incontinence were operated on by the TVT procedure and were followed up at 3, 12, and 24 months after surgery. Patients' age and body mass index (BMI) averaged 57 years and 23.9, respectively. Forty-nine women were classified as type I, 46 women type II and 56 women type III (McGuire's classification). Local anesthesia was used in the operations on 137 women (91%) and epidural or general anesthesia was used in 14 (9%). Surgical outcomes were analyzed with Kaplan-Meier survival curves. RESULTS: The subjective and objective cumulative cure rates 24 months later were 92% and 77%, respectively (P > 0.05). The TVT operation for women with type III (62%) resulted in a significantly lower cure rate compared to those with type I or with type II (83%) (P < 0.001). Post-operatively a urethral catheter was indwelt one day in 77 women (51%), two days in 14 (9%) and 3-7 days in 60 (40%). Surgical complications were encountered in 43 women (28%). The most frequent was bladder perforation in 24 women followed by postoperative difficulty in urination and de novo urgency. CONCLUSIONS: The TVT surgery was promising for the treatment of stress incontinence because of minimal surgical invasiveness and satisfactory surgical results. Women with type III incontinence resulted in fewer satisfactory outcomes than those with type I or II incontinence.     

Incontinence surgery in the older woman

PURPOSE OF REVIEW: To review recently published studies on stress urinary incontinence surgery outcomes in older women. RECENT FINDINGS: Five prospective and two retrospective studies were identified that reported tension-free vaginal tape (n = 6), colposuspension (n = 1) and cadaveric fascia transvaginal sling (n = 1) procedure results. In each study, 21-175 older women were included, with mean ages ranging from 71 to 83 years; most studies included younger comparison groups. Mean follow-ups ranged from 3 to 30 months. Subjective stress urinary incontinence 'cure/improvement' rates after surgery were significantly lower in older women when compared with younger women in only one study, although similar trends were seen in two additional studies. Intraoperative complications occurred at similar rates in older and younger women. Postoperative complications (urinary tract infection, urgency, voiding dysfunction, and mesh erosion) were more common in older women in only a few studies. SUMMARY: Recent studies demonstrate that surgery for stress urinary incontinence in older women improves symptoms, although in some reports, not to the extent seen in younger women. It is unclear if some postoperative complications are more common in older women undergoing incontinence surgery. Results from randomized trials focusing on stress urinary incontinence surgery in older women are needed.     

The clinical and urodynamic effects of the tension free bladder neck sling procedure

This study evaluated the clinical and urodynamic findings before and after tension-free bladder neck sling (TBS) procedure with Prolene tape. We enrolled 32 women who underwent TBS for genuine stress incontinence without intrinsic sphincter deficiency or severe uterovaginal prolapse. All subjects received 1-h pad test, Q-tip test, multichannel urodynamic testing, introital ultrasonography, and the Bristol Female Lower Urinary Tract Symptoms Questionnaires before and 1 year after surgery. Of the 32 subjects 27 were cured of stress incontinence, two improved, and three failed. The incidence of irritative symptoms and incomplete bladder emptying were significantly lower after surgery. The mean urethral straining angle showed a significant decrease from 73.8° preoperatively to 30.1° postoperatively. At rest the postsurgical position of the bladder neck (BN) was localized more cranially. During straining both ventral and caudal mobility of the BN decreased significantly following TBS, causing a more cranial and dorsal position of the BN. Urodynamic parameters including functional urethral length, maximal urethral closure pressure, and pressure transmission ratio showed significant increases after surgery. TBS could decrease the hypermobility of the BN and restore the BN support to prevent urinary leakage during straining, instead of urethral obstruction. The subjective and objective cure rate of stress incontinence is 84%, similar to those results reported after retropubic urethropexy and tension-free vaginal tape procedure. It is also worth emphasizing that no postoperative urinary retention occurred, although the limited number of cases makes it hard to confirm the significance of findings over the retention rate of tension-free vaginal tape.Editorial Comment: The paper challenges the concept that to be successful a TVT must be placed at the midurethra. Recent reports tell us that even when thought to be placed at the midurethra, often a TVT is closer to the bladder neck, yet it remains successful. This contribution reports on a select group of patients who had the tension-free tape placed knowingly at the UVJ rather than the traditional midurethra location. Unfortunately, this case series provides the weakest type of medical evidence, and no serious conclusions can be drawn from it. It should lead to a prospective, randomized study of the two techniques with objective outcome reporting. Only then can a truly scientific conclusion be made.
