The surgical results of the pubovaginal sling procedure using polypropylene mesh for stress urinary incontinence

OBJECTIVE: To investigate the surgical results after a pubovaginal sling procedure using polypropylene mesh in women with stress urinary incontinence (SUI). PATIENTS AND METHODS: Sixty-four women with different types of SUI underwent a pubovaginal sling procedure, using polypropylene mesh. The sling was placed at the level of the proximal half of the urethra and tied with adequate tension, but not obstructing the bladder outlet. A video-urodynamic study and transrectal ultrasonography were undertaken before and after surgery. The surgical results were assessed and the urodynamic changes compared at different stages. RESULTS: At a median follow-up of 24 months, 52 patients (81%) were completely continent, 10 (16%) had an improvement but with mild SUI, and two had persistent SUI requiring a second sling procedure. The treatment result was considered satisfactory by 55 patients (86%). The video-urodynamic study showed no significant change in voiding pressure, cystometric capacity and residual urine volume after surgery. The bladder neck opening time was increased at 7 days and the maximum flow rate increased at 3 months after surgery. Transrectal ultrasonography showed that all the polypropylene mesh slings were located beneath the bladder neck and proximal urethra, with no notable granuloma formation around the sling. CONCLUSION: The pubovaginal sling procedure is effective in treating female SUI, using polypropylene mesh as the sling material. The video-urodynamic results showed that a pubovaginal sling of polypropylene mesh causes no bladder outlet obstruction when the correct surgical technique is used.     

Comparison of video urodynamic results after the pubovaginal sling procedure using rectus fascia and polypropylene mesh for stress urinary incontinence

PURPOSE: Video urodynamic changes were compared after the pubovaginal sling procedure using rectus fascia or polypropylene mesh in women with stress urinary incontinence. MATERIALS AND METHODS: A total of 50 women with various types of stress urinary incontinence were treated with the pubovaginal sling procedure using randomly abdominal rectus fascia in 24 or polypropylene mesh in 26. The sling was placed at the level of the bladder neck and tied with sufficient tension to prevent urinary leakage without obstructing the bladder outlet. Video urodynamics were performed preoperatively, and 7 to 14 days and 3 to 6 months postoperatively in all cases. Surgical results and urodynamic changes after the pubovaginal sling procedure were compared in the 2 groups. Long-term results were evaluated at a mean followup of 2 years. RESULTS: Complete continence was achieved in 23 patients (95.8%) in the rectus fascia group and 26 (100%) in the polypropylene mesh group, including 1 initial failure with reoperation, at a median followup of 24 and 23 months, respectively. The subjective success rate was 91.6% for rectus fascia and 92.3% for polypropylene mesh. The main cause of dissatisfaction was persistent urge incontinence and dysuria in 2 cases each. In each group video urodynamics revealed a mild but nonsignificant decrease in maximum urinary flow and a significant increase in bladder neck opening time at 7 to 14 days versus baseline. However, these parameters returned to baseline within 3 to 6 months postoperatively. Voiding pressure, cystometric capacity and post-void residual urine also showed no significant change in either group after the pubovaginal sling procedure. Patients treated with a polypropylene mesh sling had a shorter operative time and hospital stay, a higher spontaneous voiding rate after catheter removal and a lower incidence of wound pain after surgery. One patient treated with polypropylene mesh had sling margin extrusion. The incidence of new onset detrusor instability and persistent dysuria was similar in the 2 groups. Transrectal sonography of the sling showed that it was located beneath the bladder neck and proximal urethra in all patients in each group. CONCLUSIONS: The results of this study show that the pubovaginal sling procedure using rectus fascia or polypropylene mesh as the sling material had similar effectiveness for treating female stress incontinence but the polypropylene group had more rapid recovery. Postoperatively video urodynamics demonstrated that the pubovaginal sling using either sling material did not cause bladder outlet obstruction with proper surgical technique.     

ANATOMICAL AND FUNCTIONAL RESULTS OF PUBOVAGINAL SLING PROCEDURE USING POLYPROPYLENE MESH FOR THE TREATMENT OF STRESS URINARY INCONTINENCE

PURPOSE: The anatomical and functional results of pubovaginal sling procedure using polypropylene mesh were investigated. MATERIALS AND METHODS: A total of 50 women with stress urinary incontinence, including 26 with type 2, 7 with mixed type 2/3 and 17 with type 3 disease, underwent the pubovaginal sling procedure using polypropylene mesh. A self-fashioned 2 cm. polypropylene mesh sling was used in all cases. The slings were fixed without tension at each side of the bladder neck. The sling was further suspended to elevate the bladder neck in patients with type 2 disease and those with a hypermobile bladder base, while it was placed without further tension in those with type 3 disease and those with a nonmobile bladder base. After the operation video urodynamics and transrectal sonography were done to evaluate functional and anatomical results. RESULTS: At a median followup of 24 months 42 women were cured, 6 had improvement and treatment had failed in 2. Although the maximum flow rate increased, no changes were noted in detrusor pressure, post-void residual urine or cystometric capacity at month 3. Transrectal sonography revealed that mean sling width plus or minus standard deviation had decreased to 13.5 +/- 3.3 mm. at 3 months. The endopelvic fascia was thicker in women with type 2 than in those with types 2/3 or 3 disease (mean 5.3 +/- 1.5 versus 3.5 +/- 1.3 mm., p = 0.001). The position of bladder neck on video urodynamics was elevated a mean of 2.01 +/- 2.01 and 3.07 +/- 2.07 cm. compared to baseline elevation during resting and straining, respectively (p = 0). No hypermobility was noted while the patients coughed and no kinking of the urethra was observed while they performed the Valsalva maneuver. Detrusor instability resolved in 6 of 8 women (75%) and new onset detrusor instability was noted in 7 (14%). In 2 women with persistent stress urinary incontinence a repeat sling procedure was necessary to treat type 3 disease and cure incontinence. The overall success rate was 96%. One patient with sling erosion into the vaginal wall was treated with simple revision. CONCLUSIONS: Fixation of a polypropylene mesh sling at the bladder neck and adequate suspension may effectively achieve a hammock effect without creating bladder outlet obstruction in patients with types 2 and 2/3 stress urinary incontinence. The anatomical and functional results of this study show that a well suspended bladder neck did not create bladder outlet obstruction after a pubovaginal sling procedure using polypropylene mesh.     

Urethral erosion after synthetic and nonsynthetic pubovaginal slings: differences in management and continence outcome

PURPOSE: We present a series of urethral erosion following a pubovaginal sling procedure due to synthetic and nonsynthetic materials and discuss their management and continence outcome. MATERIALS AND METHODS: During a 3-year period 57 patients underwent urethrolysis for urethral obstruction after receiving a pubovaginal sling. Urethral erosion, defined as sling material entering the urethral lumen, was present in 9 patients and this cohort comprises the focus of our review. In 3 patients the eroded material was synthetic, that is ProteGen (Boston Scientific, Natick, Massachusetts) in 2 and polypropylene in 1. This condition was treated with removal of the whole sling, multilayer closure of the erosion and selective use of a Martius flap. In 6 patients the eroded material was nonsynthetic, that is allograft fascia in 5 and autograft fascia in 1. This condition was treated with sling incision and multilayer closure of the urethra. Preoperative assessment included a urogynecologic questionnaire, measurement of pad use, a voiding diary, cystourethroscopy and videourodynamics. Postoperatively similar parameters were used to assess continence outcomes and the need for subsequent procedures. RESULTS: Nine patients were followed 30 months after urethrolysis. All 9 women had some manifestation of voiding dysfunction following the pubovaginal sling procedure, including urinary retention in 4, urge incontinence in 3 and mixed incontinence in 2. Urinary retention resolved in 3 patients and urge incontinence resolved in 4. Stress urinary incontinence (SUI) persisted in 2 of the 3 patients in the synthetic group, while no patient in the nonsynthetic group had recurrent SUI. There were no recurrent urethral erosions or fistulas in either group. CONCLUSIONS: Urethral erosion after a pubovaginal sling procedure can occur irrespective of the sling material. However, recurrent SUI is not an invariable outcome of the management of urethral erosion following the pubovaginal sling procedure.     

Surgical management of lower urinary mesh perforation after mid-urethral polypropylene mesh sling: mesh excision, urinary tract reconstruction and concomitant pubovaginal sling with autologous rectus fascia

Introduction and hypothesis

We present our management of lower urinary tract (LUT) mesh perforation after mid-urethral polypropylene mesh sling using a novel combination of surgical techniques including total or near total mesh excision, urinary tract reconstruction, and concomitant pubovaginal sling with autologous rectus fascia in a single operation.

Methods

We retrospectively reviewed the medical records of 189 patients undergoing transvaginal removal of polypropylene mesh from the lower urinary tract or vagina. The focus of this study is 21 patients with LUT mesh perforation after mid-urethral polypropylene mesh sling. We excluded patients with LUT mesh perforation from prolapse kits (n?=?4) or sutures (n?=?11), or mesh that was removed because of isolated vaginal wall exposure without concomitant LUT perforation (n?=?164).

Results

Twenty-one patients underwent surgical removal of mesh through a transvaginal approach or combined transvaginal/abdominal approaches. The location of the perforation was the urethra in 14 and the bladder in 7. The mean follow-up was 22 months. There were no major intraoperative complications. All patients had complete resolution of the mesh complication and the primary symptom. Of the patients with urethral perforation, continence was achieved in 10 out of 14 (71.5 %). Of the patients with bladder perforation, continence was achieved in all 7.

Conclusions

Total or near total removal of lower urinary tract (LUT) mesh perforation after mid-urethral polypropylene mesh sling can completely resolve LUT mesh perforation in a single operation. A concomitant pubovaginal sling can be safely performed in efforts to treat existing SUI or avoid future surgery for SUI.     

Long-term results of surgical treatment for female stress urinary incontinence

OBJECTIVE: To compare the long-term success rates of bladder neck suspension (BNS) and pubovaginal sling procedure in different types of female stress urinary incontinence (SUI) in order to identify appropriate treatment strategies for SUI. METHODS: A total of 157 women who received anti-incontinence surgery were followed-up for a mean period of 58.1 +/- 33.9 months. The surgical outcome was analyzed and was compared among the different types of SUI and among BNS and pubovaginal sling procedures. RESULTS: SUI was classified as type I in 16 patients, type II in 111 patients, and type III in 34 patients. Surgical procedures included Gittes BNS (n = 62), Raz BNS (n = 53), and pubovaginal sling procedure (n = 42). The total success rate was 77.1%, including a 38.2% cure rate and a 38.9% significantly improved rate. Analysis of the results revealed that type III SUI had the lowest success rate (67.6%), while the pubovaginal sling procedure had the best success (93.9%) and cure rates (54.8%). The success rates of BNS were significantly lower than that of pubovaginal sling in type III SUI, less favorable in type II SUI, but remained high in type I SUI. 75% of patients with treatment failure had recurrence within the fist postoperative year. CONCLUSIONS: In this series of patients, the long-term cure rates of anti-incontinence surgeries are not satisfactory. BNS procedures had satisfactory results only in type I SUI while the pubovaginal sling procedure had better results in both types II and III SUI. The pubovaginal sling procedure might have better long-term results in the treatment of all types of SUI.     

Broad based tension-free synthetic sling for stress urinary incontinence: 5-year outcome

PURPOSE: The use of nonabsorbable synthetic material has been questioned due to reports of erosion and infection. We present the 5-year followup outcome of stress urinary incontinence (SUI) treated using polypropylene mesh as a pubovaginal sling. MATERIALS AND METHODS: A retrospective analysis was performed of 58 consecutive patients who underwent pubovaginal sling procedures using polypropylene mesh since April 1996 for types II and III SUI at our institution. The technique included a single midline anterior vaginal wall incision with full-thickness flaps. Broad based polypropylene mesh was used to support the vesicourethral junction entering the retropubic space through the endopelvic fascia and bone anchors were used for fixation. Patient satisfaction was evaluated during followup office visits and/or telephone interview by an individual not involved in any surgeries. All procedure failures were evaluated by urodynamics. RESULTS: Of the 58 patients 49 were available for analysis. Average followup was 59.34 months (range 29 to 77). Of the 49 patients 40 (81.63%) were dry and 2 (4.08%) improved (1 pad daily). De novo urgency and urgency related incontinence was reported in 1 case each. Three patients (8.16%) had recurrent SUI, while prolonged retention developed with subsequent urethrolysis required in 2 (4.08%). None of the patients have experienced infection, nonhealing or erosion of the synthetic slings to date. CONCLUSIONS: In our experience polypropylene mesh used as a broad based tension-free sling was successful for treating all types of SUI. In our opinion technique and case selection have a bearing on outcomes.     

Variations in strategy for the treatment of urethral obstruction after a pubovaginal sling procedure

PURPOSE: We evaluated the success of several techniques for treating urethral obstruction and erosion after a pubovaginal sling procedure. MATERIALS AND METHODS: Between April 1998 and June 1999, 32 women 33 to 79 years old (average age 62) who underwent a pubovaginal sling procedure with various materials were referred for the assessment of urethral obstruction. Patients were evaluated with a urogynecologic history, physical examination, voiding diary, cystoscopy and video urodynamics. Surgical procedures to resolve urethral obstruction were performed transvaginally and the specific techniques used were based on the type of sling material, urethral erosion and concomitant stress incontinence or other urethral pathology. Outcome measures were assessed by disease specific quality of life questionnaires, voiding diary and urogynecologic questionnaire. RESULTS: Preoperatively 30 of the 32 women (93.7%) noticed urge incontinence, 20 (62.5%) performed intermittent self-catheterization, 6 (18.7%) had an indwelling catheter and 3 (9%) complained of concomitant stress urinary incontinence. After the sling takedown 29 patients (93.5%) achieved efficient voiding within week 1 postoperatively. Urge incontinence symptoms resolved in 20 cases (67%) but stress incontinence developed in 3 (9%). Of the 32 women 27 (84%) indicated that continence was much better than before the initial sling procedure. CONCLUSIONS: Managing urethral obstruction after a pubovaginal sling procedure is challenging. Using various techniques based on sling material, urethral erosion and bladder neck integrity a successful outcome is possible in the majority of cases.     

Management of vaginal erosion of polypropylene mesh slings

PURPOSE: The SPARC (American Medical Systems, Minneapolis, Minnesota) polypropylene sling has recently been introduced as an alternative delivery system to TVT (Ethicon, New Brunswick, New Jersey) tension-free vaginal tape for placement of a tension-free mid urethral sling. Erosion must always be considered a risk of synthetic materials. We present 4 cases of vaginal erosion of polypropylene mesh placed with this system and the successful conservative management done. MATERIALS AND METHODS: A total of 90 patients received a SPARC polypropylene pubovaginal sling at our institution between October 1, 2001 and October 1, 2002. During followup 3 of our patients and 1 patient with tension-free vaginal tape who was referred from elsewhere presented with vaginal exposure of the mesh. RESULTS: Two patients described persistent vaginal discharge 6 weeks postoperatively, including 1 who complained primarily of partner discomfort during sexual intercourse. Two patients were completely asymptomatic and mesh erosion was discovered at routine physical examination 6 weeks postoperatively. Pelvic examination demonstrated vaginal exposure of the mesh in all cases. Each patient was observed conservatively and 3 months postoperatively all 4 had complete spontaneous epithelialization over the mesh. None had stress incontinence, urgency or urge incontinence, all emptied the bladder to completion and all patients were completely satisfied with the procedure. CONCLUSIONS: The recent literature suggests that polypropylene mesh erosion should be treated with complete removal of the sling material. We present 4 cases of vaginal erosion of polypropylene slings that were managed conservatively with observation and resulted in complete spontaneous healing. Sling preservation with continued patient continence and satisfaction is a feasible option in those with vaginal exposure of polypropylene mesh.     

Polypropylene mesh tape for stress urinary incontinence: complications of urethral erosion and outlet obstruction

PURPOSE: Gynecare tension-free vaginal tape (Ethicon, Inc., New Brunswick, New Jersey) is a propylene mesh tape recently introduced in the United States as minimally invasive treatment for stress urinary incontinence. We report the combined experience at 3 tertiary care institutions with graft erosion and bladder outlet obstruction after procedures performed elsewhere. MATERIALS AND METHODS: We reviewed the records of 5 patients with complications who presented to 1 of 3 institutions after polypropylene mesh tape placement. All pertinent information was obtained from the medical records and the operating surgeon at the referring institution. RESULTS: Treatment was required in 2 patients with urethral erosion, 1 with vaginal and bladder erosion, and 2 with bladder outlet obstruction. Common presenting symptoms included urge, urge incontinence and gross hematuria. Cystoscopy showed polypropylene graft erosion at the urethra or through the bladder wall. Each patient required explantation of the polypropylene mesh tape and further surgery to restore continence. The graft was divided transvaginally in the 2 patients presenting with outlet obstruction. Urge incontinence resolved and they returned to complete spontaneous voiding. CONCLUSIONS: High clinical suspicion is necessary when evaluating patients presenting with urinary symptoms after polypropylene mesh tape placement. Bladder outlet obstruction and possible graft erosion should be considered.     

Polytetrafluoroethylene sling for failure in female stress incontinence surgery

Summary Surgery for stress urinary incontinence (SUI) in women with previous interventions is often difficult and yields poor results. A total of 33 women with recurrent SUI underwent placement of a polytetrafluoroethylene (PTFE) sling after a mean of 1.5 (range, 1–3) unsuccessful operations. Preoperative bladder instability (BI) was ruled out in all cases. The patients' mean age was 54 (range, 34–79) years. In all, 64% had SUI and 36% had SUI and incontinence at rest. The Aldrige-Stoeckel technique is used with insertion of a 2×30 cm sling instead of fascia lata. Mean operating time was reduced in 40 minutes. After a mean follow-up period of 13 months, 72% of the patients achieved continence without retention (complete success). Altogether, 16 patients (48%) required self-catheterization after discharge, with the voiding imbalance lasting for more than 3 months in only 4 cases (12% of the total). Three patients underwent surgery for outlet obstruction. There were five abdominal wound infections but no vaginal wound infection. Two slings have since been removed (one partially), but none has eroded through the urethra. The PTFE sling is a reasonable option for this group of patients. Retention is usually self-limited, and most complications can be managed successfully.     

Disabling complications with slings for managing female stress urinary incontinence

OBJECTIVE

To report an increase in the referral of patients with disabling complications after the failure of conservative therapy, their presentation, final surgical management and clinical outcome, following the use of non‐autologous slings (NAS), currently the primary surgical procedure for managing stress urinary incontinence (SUI) in women.

PATIENT AND METHODS

Thirty‐eight patients (mean age 64 years) required surgical management for disabling complications after placing a NAS for SUI. Sling types were synthetic (25), xenografts (six) and allografts (four). Twenty (53%) patients presented with bladder outlet obstruction, 13 (34%) with sling erosion, three (8%) with worsened SUI, and two (5%) with unobstructive severe urgency and frequency.

RESULTS

The sling was dissected and incised with no complication in 19 of 20 patients. One had a posterior urethral defect during sling dissection. Twelve patients (60%) acquired normal voiding and were continent. Among the 13 patients who had the sling dismantled and urethrolysis, two had recurrent or persistent SUI, two de‐novo urgency/frequency and one developed osteitis pubis. Three patients with disabling SUI received a pubovaginal sling placed proximal to the bladder neck, and had an overall improvement in their urinary control with no retention. Two unobstructed patients with urgency and frequency did not improve with anticholinergic medication and pelvic floor therapy, and are now candidates for botulinum toxin injection or neurostimulation.

CONCLUSIONS

The complication rate with periurethral NAS for managing SUI in females is substantial. Patients with refractory urgency/frequency after the sling need a complete evaluation with cystoscopy and video‐urodynamics. Obstruction and erosion are the commonest problems and require surgical correction.     

An assessment of the surgical outcome and urodynamic effects of the pubovaginal sling for stress incontinence and the associated urge syndrome.

PURPOSE: We assessed the urodynamic changes after pubovaginal sling procedure for stress incontinence, particularly in regard to the associated symptoms of urgency, frequency, nocturia and urge incontinence, known as the urge syndrome. MATERIALS AND METHODS: A total of 85 women with proved stress incontinence underwent a pubovaginal sling procedure using rectus fascia between 1992 and August 1996. Of the women 41 (48%) had undergone previous anti-incontinence surgery and 59 (69%) had the associated urge syndrome. There was at least some degree of hypermobility in 51 cases and type III stress incontinence was diagnosed in 34. Patients were assessed with a questionnaire and video urodynamics preoperatively and 3 months postoperatively. Preoperative and postoperative ambulatory studies were performed in 25 cases. RESULTS: Of the 85 patients 83 (97%) were symptomatically cured of stress incontinence. The urge syndrome resolved in 32 patients (69%), almost all of whom had a closed bladder neck at rest. Overall bladder neck incompetence at rest decreased from 57 to 18% (p<0.001). Of 27 patients with the persistent urge syndrome postoperatively 9 (41%) had an open bladder neck at rest compared to 4 of 50 (8%) without urge incontinence (p<0.01). Despite symptomatic control of stress incontinence in 83 patients (97%), only 66 were satisfied with the surgical result, mainly because of the persistent urge syndrome in 27. Despite care to avoid obstruction overall, there were statistically significant obstructive changes in detrusor pressure at maximum flow rate, maximum flow rate and residual urine volumes. CONCLUSIONS: The pubovaginal sling is effective in curing genuine stress incontinence and, when correctly placed at the right tension, the associated urge syndrome also can be managed, usually by achieving bladder neck closure at rest. However, despite careful maneuvers, obstruction occasionally persists.     

The use of polypropylene mesh as a transobturator sling for the treatment of female stress urinary incontinence (early experience with 40 cases)

This study evaluated the use of traditional polypropylene mesh, used in hernias repair, as a sling in the treatment of female stress urinary incontinence (SUI). Forty patients diagnosed with SUI underwent transobturator sling fashioned from the ordinary polypropylene mesh (vypro II®). Each lateral end of the tape is secured by a zero prolene suture. The procedure was then done outside-in, and the patients were followed up. The mean operative time was 40–60 min when the procedure was performed alone or accompanied with associated pelvic floor repair. Thirty-five patients (87.5%) were cured, and two patients (5%) significantly improved, but the procedure failed in three patients (7.5%), and the slings were removed because of vaginal erosion. Polypropylene mesh transobturator sling is an easy and cheap method for the treatment of female SUI with a high success rate.     

Laparoscopic removal of pubovaginal polypropylene tension-free tape slings.

OBJECTIVES: Complications of polypropylene pubovaginal tension-free tape slings (TVT, SPARC, and others), such as erosion into the bladder or chronic pain attributed to the mesh sling are rare events; however, when they occur, it may necessitate removal of the sling. To date, removal through a laparotomy incision or by operative cystoscopy has been the most common approach. We present 5 cases of a laparoscopic approach for removal of polypropylene pubovaginal tension-free tape slings. METHODS: We report 5 cases of laparoscopic removal of TVT mesh. Three were removed for mesh erosion into the bladder, and 2 were removed secondary to the patients having persistent pain and discomfort attributed to the sling. An intraperitoneal approach was used to enter the retropubic space to remove the sling. Dissection was completed with a Harmonic scalpel blade as well as blunt dissection to identify the mesh sling retropubically. Average operating time was 104 minutes. Average blood loss was 70 mL. Average hospital stay was <23 hours. Postoperative courses were uneventful; however, 4 of the 5 patients continue to have urgency and frequency symptoms following sling removal. CONCLUSION: These cases illustrate the use of laparoscopy in the removal of polypropylene pubovaginal tension-free tape slings for bladder erosion or persistent pain, or both, attributed to the sling. Erosion and pain are known complications of polypropylene pubovaginal slings and may cause significant morbidity like persistent detrusor instability or urge incontinence, or both. Patients must be informed of these risks and possible complications before making their decision to undergo surgery.     

Clinical and urodynamic outcomes of pubovaginal sling procedure with autologous rectus fascia for stress urinary incontinence

AIM: We report the clinical and urodynamic outcomes of the pubovaginal sling procedure with autologous rectus fascia for stress urinary incontinence (SUI) and determined the urodynamic parameters that could predict the occurrence of postoperative voiding difficulty. METHODS: Between 1998 and 2005, a total of 29 consecutive women with SUI underwent pubovaginal sling surgery with autologous rectus fascia. Patients were preoperatively and postoperatively evaluated with regard to symptoms and urodynamic findings including uroflowmetry (UFM), postvoid residual urine volume (PVR), filling cystometry (CMG) and pressure flow study (PFS). RESULTS: Overall SUI was cured in 23 patients (80%) and improved in 3 patients (10%). Three patients (10%) who developed persistent urinary retention or severe voiding difficulty after surgery underwent urethrolysis. Of 17 patients who had urgency before the pubovaginal sling, urgency was cured postoperatively in seven, while de novo urgency appeared in one patient. Maximum flow rate (Qmax) in UFM was significantly decreased (P < 0.05) and PVR was increased (P = 0.08) after surgery. PFS showed a significant increase in detrusor opening pressure and detrusor pressure at Qmax (P < 0.01) after surgery. Eight patients (28%) needed prolonged intermittent self-catheterization. Patients who had PVR >100 mL (P < 0.05) or Qmax < or = 20 mL/s (P = 0.09) in preoperative UFM were more likely to require prolonged intermittent catheterization after surgery. CONCLUSIONS: The pubovaginal sling procedure with autologous rectus fascia is an effective treatment for SUI. A comparison of preoperative and postoperative urodynamic parameters indicates an increase in urethral resistance after pubovaginal sling surgery. PVR >100 mL and Qmax < or = 20 mL/s before surgery are risk factors for postoperative voiding difficulty.     

Transvaginal urethrolysis after obstructive urethral suspension procedures

Obstructive uropathy after an operation for stress incontinence was treated by transvaginal urethrolysis in 13 women. Bladder outlet obstruction developed after retropubic urethropexy in 6 patients, after needle suspension in 4 and after a pubovaginal sling operation in 3. Transvaginal urethrolysis was accompanied by a needle suspension in 2 patients, an Inglemann-Sundberg denervation in 1 and a pubovaginal sling in 1. Of 13 patients 10 are voiding and none has stress incontinence but 3 continue to perform intermittent self-catheterization.     

Contemporary role of autologous fascial bladder neck slings: a urology perspective

Fascial slings remain a successful and durable option for treatment of female stress urinary incontinence (SUI). With limited risk of disease transmission, extrusion, or complications associated with mesh, use of autologous fascia is an attractive option, particularly for complex reconstructive cases. With generally robust outcomes, pubovaginal slings also continue to be a viable option for treatment of primary SUI after appropriate patient counseling regarding risks of bladder outlet obstruction and de novo urgency symptoms.     

Prospective analysis of patients treated with a distal urethral polypropylene sling for symptoms of stress urinary incontinence: surgical outcome and satisfaction determined by patient driven questionnaires

PURPOSE: We evaluated the safety and efficacy of the distal urethral polypropylene sling for stress urinary incontinence using patient self-assessment by questionnaires. MATERIALS AND METHODS: We performed a prospective study of all consecutive patients who underwent a mid distal urethral sling procedure between November 1999 and February 2002. Surgical outcome was determined by symptom, bother and quality of life questionnaires completed by the patients. The physicians were blinded to patient responses. These outcomes were compared to the SEAPI determined by the physician and to physical examination findings. RESULTS: There were 301 patients, of whom 2.3% required treatment for persistent stress urinary incontinence (SUI) after the polypropylene sling procedure. In the 92 patients with a minimum followup of 12 months the objective cure rate was 92%. The patient determined subjective success rate (cure and improved greater than 50%) was 89%. On questionnaires only 69% of the patients reported no symptoms of SUI under any circumstance and the same number reported never being bothered by SUI. The physician determined SEAPI overestimated patient self-reported symptoms by 10% to 50% depending on the symptom. CONCLUSIONS: The polypropylene sling represents an inexpensive, safe and simple alternative treatment for patients with stress urinary incontinence. The procedure provides high objective and physician determined cure rates but a lower patient self-reported subjective cure rate. Patient self-assessment of symptoms, bother and quality of life should be an integral part of the outcome of stress urinary incontinence surgery.     

Bladder neck sling for treatment of neurogenic incontinence in children with augmentation cystoplasty: long-term followup

PURPOSE: We retrospectively reviewed the outcome and long-term followup (mean 4.16 years) of bladder neck slings for the treatment of neurogenic urinary incontinence in 58 patients (15 males) who also underwent bladder augmentation. MATERIALS AND METHODS: A total of 58 patients with neurogenic bladder (43 females and 15 males, median age 11.4 years) underwent a rectus fascial sling procedure as part of the reconstructive efforts for continence between July 1991 and July 2003. Criteria for enhancement of bladder outlet resistance included a detrusor leak point pressure of less than 45 cm H2O, an open bladder neck during bladder filling at low detrusor pressures and clinical evidence of stress incontinence. RESULTS: Followup ranged from 1 year to 10 years, 3 months (mean 4.16 years). A total of 51 patients (88%) obtained good continence results. Five females and 2 males remained incontinent following the sling procedure. Four females underwent a secondary open bladder neck procedure at a mean of 18 months after the initial procedure (artificial urinary sphincter in 2, bladder neck closure in 2). Two male patients (5 and 17 years old) had daily underwear staining or dampness with exercise or transfer. CONCLUSIONS: We consider bladder neck slings the procedure of choice for the enhancement of bladder outlet resistance in the majority of patients with neurogenic bladder who need augmentation cystoplasty and whom we do not expect will be capable of voiding spontaneously. In males and females satisfactory long-term continence can be expected with the use of the rectus fascial sling.
