Comparison of the main body of the external anal sphincter muscle cross-sectional area between women with and without prolapse

The aim of the study was to compare the main body of the external anal sphincter (EAS) cross-sectional area (CSA) of women with and without pelvic organ prolapse. Pelvic magnetic resonance imaging (MRI) scans of 40 women were selected for analysis. Of these women, 20 had pelvic organ prolapse and 20 had normal support. Of the women with normal support, 10 had known major levator ani (LA) muscle defects and 10 had normal LA muscles. The same was true for the women with pelvic prolapse: half had major LA defects and half had no LA defects. All patients had previously completed pelvic MRI in the supine position. 3-D models of the EAS were made and CSA of the EAS perpendicular to the fiber direction were measured circumferentially at 30° intervals. Univariable and multivariable analyses were performed. The mean CSA did not significantly differ between women with prolapse and normal support regardless of LA defect status (normal/−LA defect = 1.13 cm², prolapse/−LA defect = 0.86 cm², p = 0.065; normal/+LA defect = 1.08 cm², prolapse/+LA defect = 1.28 cm², p = 0.28). Women with prolapse and LA defects had a 49% larger mean muscle CSA compared to prolapse patients without LA defects (p = 0.01). This difference associated with defect status in prolapse patients was not seen in women with normal support. Women with prolapse alone had external anal sphincter CSAs that were comparable to women with normal support. However, women with both prolapse and a major levator ani defect had larger external anal sphincter CSAs compared to prolapse patients without levator ani defects.     

Pelvic floor disorders among indigenous women living in Xingu Indian Park, Brazil

Introduction and hypothesis  Current assessment for pelvic floor disorders (PFDs) allows comparison between different communities. Methods  A total of 377 indigenous women living in Xingu Indian Park were evaluated. The pelvic organ prolapse quantification (POP-Q) was the system used to quantification the staging of pelvic support. The pelvic floor muscle strength was assessed by a perineometer. Logistic regression analysis was used to determine risk factors that were associated with prolapse. Results  Only 5.8% of women reported urinary incontinence. The overall distribution of POP-Q stage system was the following: 15.6% stage 0, 19.4% stage I, 63.9% stage II and 0.8% stage III. Parity and age were the risk factors for pelvic organ prolapse (p < 0.0001). Conclusions  Urinary incontinence was uncommon in Xingu indigenous women. Like non-indigenous communities, age and parity were the most important risk factors to the genital prolapse.     

Magnetic resonance assessment of pelvic anatomy and pelvic floor disorders after childbirth

To compare pelvic anatomy, using magnetic resonance imaging, between postpartum women with or without pelvic floor disorders. We measured postpartum bony and soft tissue pelvic dimensions in 246 primiparas, 6–12-months postpartum. Anatomy was compared between women with and without urinary or fecal incontinence, or pelvic organ prolapse; P < 0.01 was considered statistically significant. A deeper sacral hollow was significantly associated with fecal incontinence (P = 0.005). Urinary incontinence was marginally associated with a wider intertuberous diameter (P = 0.017) and pelvic arch (P = 0.017). There were no significant differences in pelvimetry measures between women with and without prolapse (e.g., vaginal or cervical descent to or beyond the hymen). We did not detect meaningful differences in soft tissue dimensions for women with and without these pelvic floor disorders. Dimensions of the bony pelvis do not differ substantially between primiparous women with and without postpartum urinary incontinence, fecal incontinence and prolapse.     

Assessment of sexual function in women with pelvic floor dysfunction

Forty-seven women participated in a pilot study for a multi-centre randomized controlled trial of the effectiveness of pelvic floor muscle training (PFMT) for women with prolapse. Women with symptomatic stage I or II prolapse [measured by Pelvic Organ Prolapse Quantification (POP-Q)] were randomized to a 16-week physiotherapy intervention (PFMT and lifestyle advice; n = 23) or a control group receiving a lifestyle advice sheet (n = 24). Symptom severity and quality of life were measured via postal questionnaires. Blinded POP-Q was performed at baseline and follow-up. Intervention women had significantly greater improvement than controls in prolapse symptoms (mean score decrease 3.5 versus 0.1, p = 0.021), were significantly more likely to have an improved prolapse stage (45% versus 0%, p = 0.038) and were significantly more likely to say their prolapse was better (63% versus 24%, p = 0.012). The data support the feasibility of a substantive trial of PFMT for prolapse. A multi-centre trial is underway.     

Does avulsion of the puborectalis muscle affect bladder function?

Introduction and hypothesis  The levator ani muscle is generally thought to play a role in urinary continence, with incontinence assumed to be due to abnormal muscle function or morphology. This study examined whether avulsion of the puborectalis muscle is associated with symptoms or signs of bladder dysfunction. Methods  In a retrospective observational study, we reviewed the records of 425 women who had attended a urogynecological unit for independent flowmetry, multichannel urodynamic testing, and 4D pelvic floor ultrasound. Results  Mean age was 55 years (range, 17–87 years). Of 420 women with complete datasets, 104 (25%) were diagnosed with a puborectalis muscle avulsion. These women were less likely to suffer from stress urinary incontinence (SUI; P < 0.001) and urodynamic stress incontinence (USI; P = 0.065) and more likely to present with symptoms of prolapse (P < 0.001) and show signs of voiding dysfunction (P = 0.005). The negative association between avulsion and SUI persisted in multivariate models. Conclusion  Puborectalis muscle trauma is not associated with an increased risk of SUI or USI in a urogynecological population, even when controlling for symptoms or signs of prolapse and previous surgery.     

Do overactive bladder symptoms improve after repair of anterior vaginal wall prolapse?

This study aims to evaluate the changes of overactive bladder symptoms to anterior vaginal wall prolapse repair. Ninety-three consecutive women with symptomatic anterior vaginal wall prolapse ≥ stage II and coexistent overactive bladder symptoms were prospectively studied using a urinalysis, urodynamics, King’s Health Questionnaire (KHQ), Prolapse Quality of Life (P-QOL) questionnaire and pelvic organ prolapse quantification (POP-Q) system before and 1 year after surgery. All women underwent a standard fascial anterior repair. Postoperatively, urinary frequency, urgency and urge incontinence disappeared in 60, 70 and 82% of women respectively (p value < 0.001). The vaginal examination findings as well as the quality of life of the women assessed using KHQ and P-QOL significantly improved after surgery (p value < 0.001). This study has demonstrated that anterior vaginal repair does produce significant improvement in overactive bladder symptoms. A larger longer-term study is required to assess if these changes persist over time.     

Urinary incontinence after obstetric anal sphincter injuries (OASIS)—is there a relationship?

This study aimed to compare urinary symptoms and its impact on women’s quality of life after obstetric anal sphincter injuries (OASIS) with a matched control group in the short term. The study group consisted of 100 primiparous women with OASIS and 104 controls who sustained a second-degree tear or had a mediolateral episiotomy performed. All women completed a validated International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF) questionnaire 10 weeks after delivery. Compared to controls, significantly more women with OASIS reported overall urinary incontinence (21.2 vs 38%, p = 0.005) and had significantly worse quality of life score (incontinence score: 2.42 vs 1.2; p = 0.008). Significantly more women with OASIS suffered from stress urinary incontinence (33 vs 14%; p = 0.002; OR 3.06; CI = 1.54–6.07) than controls. Logistic regression analysis revealed that OASIS and a prolonged (>50 min) second stage of labour were independent risk factors for the development of stress urinary incontinence. This study highlights the importance of inquiring about urinary incontinence in women with OASIS. Presented to the German Forum Urodynamicum 2006 by IS (11.03.2006) and received the Eugen-Rehfisch Award of the German Forum Urodynamicum.     

Effect of anatomic urethral length on the correlation between the Q-tip test and descent at point Aa of the POP-Q system

The objective of this study is to evaluate the effect of anatomic urethral length on the relationship between descent at point Aa of the pelvic organ prolapse quantification (POP-Q) system and the Q-tip straining angle. The records of 323 patients who were evaluated for urinary incontinence were reviewed. Prolapse staging was performed using the POP-Q system. Urethrovesical junction hypermobility defined as a maximal straining angle ≥30° was assessed with the Q-tip test. Urethral length was measured with a urethral profilometer. A substantial correlation was found between descent at point Aa and the straining Q-tip angle (r = 0.65, p < 0.0001). There was no correlation between the anatomic urethral length and straining Q-tip angle (r = −0.01, p = 0.8). Urethral length does not affect the straining Q-tip angle. Point Aa is a strong predictor of an abnormal straining Q-tip angle in women with stage I anterior vaginal wall prolapse or greater.     

Urinary retention is uncommon after colpocleisis with concomitant mid-urethral sling

The purpose of this study was to evaluate the effect of colpocleisis and concomitant mid-urethral sling on voiding function. This is an IRB-approved, retrospective case series of women who underwent a colpocleisis with concomitant synthetic mid-urethral sling for treatment of stress urinary incontinence (SUI) between January 2005 and September 2007. Thirty-eight women with pelvic organ prolapse and SUI symptoms were included. Thirty percent had a post-void residual (PVR) greater than 100 ml preoperatively. PVRs were normal in all but two women after surgery. Median prolapse and urinary subscales of the pelvic floor distress inventory improved significantly after surgery [75 (50–100) vs. 0 (0–38), p < 0.0001 and 44 (8–100) vs. 0 (0–50), p < .0001, respectively]. Colpocleisis with concomitant mid-urethral sling improves urinary symptoms without causing significant urinary retention. This combination may be offered to elderly women with SUI who are undergoing colpocleisis regardless of preoperative PVR.     

Sexual function following surgery for urodynamic stress incontinence

The objective of this study was to compare sexual function in women before and after surgery for urodynamic stress incontinence in the absence of pelvic organ prolapse. This was a prospective questionnaire survey. Fifty-four women undergoing surgery (tension-free vaginal tape/tension-free vaginal tape-obturator) for urodynamic stress incontinence with no evidence of detrusor overactivity or concomitant prolapse were assessed preoperatively and 6 months post operatively. Assessment was based on the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ), the International Consultation on Incontinence Questionnaire (ICIQ) and the Patient Global Impression of Improvement. Paired t-tests were used for comparing pre- and post-op scores and unpaired t-tests for comparing observations between groups. Spearman’s rank correlation was used for testing whether two numerically scored items were related, and McNemar test was used to compare pre- and postoperative responses to individual questions. ICIQ scores showed significant improvement after surgery (p < 0.001). Women completing PISQ were significantly younger (mean = 54) than those who did not (mean = 65; p < 0.001). The total PISQ score was better postoperatively (preoperative = 87.2, postoperative = 92.7; p < 0.001), with improvements in both the physical (preoperative = 31.0, postoperative = 35.2; p < 0.001) and partner-related domains (preoperative = 18.8, postoperative = 19.9; p = 0.002) but no improvement in behaviour emotive domains (preoperative = 37.3, postoperative = 37.6; p = 0.70). There was a reduction in episodes of coital incontinence postoperatively (preoperatively = 16/54, postoperatively = 39/54; p < 0.002). Previous vaginal surgery, oestrogen status of respondents and hysterectomy status did not affect the PISQ. Surgical correction of stress incontinence is associated with an improvement in sexual function.     

Incontinence pessaries: size, POPQ measures, and successful fitting

Introduction and hypothesis  The aim of the study was to determine whether successful incontinence pessary fitting or pessary size can be predicted by specific POPQ measurements in women without advanced pelvic organ prolapse. Methods  In a multicenter study, women with stress urinary incontinence (SUI) and POPQ stage ≤2 were randomized to three treatment arms: (1) incontinence pessary, (2) behavioral therapy, or (3) both. This study evaluates incontinence pessary size, POPQ measures, and successful fitting in the 266 women assigned to treatment arms 1 and 3. Results  Two hundred thirty-five women (92%) were successfully fitted with an incontinence ring (n = 122) or dish (n = 113). Hysterectomy, genital hiatus (GH), and GH/total vaginal length (TVL) ratios did not predict unsuccessful fitting (p > 0.05). However, mean TVL was greater in women successfully fitted (9.6 vs. 8.8 cm, p < 0.01). Final pessary diameter was not predicted by TVL, point D, or point C (p > 0.05). Conclusions  The vast majority of women with SUI can be successfully fitted with an incontinence pessary, but specific POPQ measures were not helpful in determining incontinence pessary size.

Sexual Function in Women with and without Urinary Incontinence and/or Pelvic Organ Prolapse

The sexual function of women with and without urinary incontinence and/or pelvic organ prolapse (UI/POP) was compared using a condition-specific validated questionnaire, the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ). Eighty-three women with UI/POP and 56 without agreed to participate. PISQ scores were significantly lower among women with UI/POP than in those without (P = 0.003). No differences in the stages of sexual excitement were noted between groups. The frequency of intercourse was less with UI/POP than without (P = 0.04). Women with UI/POP restricted sexual activity for fear of losing urine more frequently than did those without (P= 0.005). No differences were reported in patients’ or partners’ sexual satisfaction. This study found that women with UI/POP have poorer sexual functioning than those without, as measured by the PISQ, and report less frequent sexual activity. In addition, women with UI/POP are more likely to restrict sexual activity for fear of incontinence, although they report similar levels of satisfaction with their sexual relationships as do women without UI/POP.     

Does bladder neck descent increase with age?

It is assumed that pelvic organ descent and prolapse increase with age. Epidemiological studies support this assumption. We aimed to define the relationship between age and bladder neck descent (BND) in a retrospective observational study on 790 women referred for evaluation of pelvic floor disorders. Bladder neck descent, cystocele descent and urethral rotation were evaluated on maximal Valsalva manoeuvre, using trans-labial ultrasound. There was a weak negative correlation between bladder neck descent on Valsalva and age (r = −0.154, p < 0.001), which was absent in nulliparous women (n = 107) and stronger (r = −0.213, p < 0.001) in parous women (n = 683). This relationship was evident from the age of 50 years onwards and may be explained by increased tissue stiffness after menopause. The difference observed between parous and nulliparous women is intriguing and raises the issue of obstetric confounders such as historical changes in the likelihood of significant pelvic floor trauma.     

Are persistent or recurrent symptoms of urinary incontinence after surgery associated with adverse effects on sexual activity or function?

We sought to determine if postoperative urinary incontinence (UI) symptoms are associated with (1) sexual activity status and (2) sexual function using validated health-related quality of life instruments. In this mailed cross-sectional survey of 687 women who underwent stress incontinence surgery, 437 (63.6%) completed a questionnaire protocol. Clinical and sociodemographic factors independently associated with sexual activity status were identified with logistic regression. Sexually active respondents completed the Pelvic Organ Prolapse and Urinary Incontinence Sexual Function Questionnaire (PISQ-12) as a measure of sexual function. Factors independently associated with sexual function were identified with linear regression. Sexual activity was reported by 57.6% (252/437). The likelihood that a respondent was sexually active was moderated by an interaction between age and UI symptom severity (p = 0.059). Among the sexually active women, increasing UI symptom severity was associated with poorer sexual function (r = −0.42, p < 0.001). The severity of postoperative recurrent or persistent UI is associated with a lower probability of being sexually active and an adverse effect on sexual function.     

The development of an Incontinence Treatment Motivation Questionnaire for patients undergoing pelvic floor physiotherapy in the treatment of stress incontinence

Introduction and hypothesis  The aim of this paper is to develop a motivation questionnaire regarding perseverance in pelvic floor muscle training (PFMT) supervised by physiotherapists for stress urinary incontinence. Methods  Sixteen semi-structured interviews were conducted in women with stress urinary incontinence that revealed 15 common themes; 117 items were constructed and reviewed by continence advisors. Surviving items (n = 73) were administered to 210 women. Data were analysed for item properties, factor analysis was used to examine the questionnaire structure and tests of convergence/divergence used to check for sensitivity. Results  The Incontinence Treatment Motivation Questionnaire (ITMQ) comprises 18-items in five scales, assessing attitudes towards treatment (72.62% of explained variance; α = 0.87), reasons for not doing PFMT (55.73%; α = 0.74), living with incontinence (62.70% variance; α = 0.70), desire for treatment (65.37% variance; α = 0.74) and the effect of incontinence severity on PFMT (51.62% variance, α = 0.68). Scales were generally sensitive to known group differences. Conclusions  This study represents the first effort to develop a motivation scale for PFMT. This validated Motivation Questionnaire is an instrument to test the impact of motivation upon cure, in PFMT. The work was carried out at the Pelvic Floor Unit, St George Hospital, Kogarah, NSW, Australia 2217.     

Clarification and confirmation of the Knack maneuver: the effect of volitional pelvic floor muscle contraction to preempt expected stress incontinence

The aim of the study was to determine the immediate effect of timing a pelvic muscle contraction with the moment of expected leakage (the Knack maneuver) to preempt cough-related stress incontinence. Women performed a standing stress test using three hard coughs without and then with the Knack maneuver. Volume of urine loss under both conditions was quantified with paper-towel test. Two groups of women were tested: nonpregnant women (n = 64) and pregnant women (n = 29). In nonpregnant women, wetted area decreased from a median (range) of 43.2 (0.2–183.7) cm² without the Knack maneuver to 6.9 (range of 0 to 183.7 cm²) with it (p < 0.0001); while in pregnant women it decreased from 14.8 (0–169.7) cm² to 0 (0–96.5) cm², respectively (p = 0.001). This study confirms the effect from the Knack maneuver as immediate and provides a partial explanation for early response to widely applied pelvic muscle training regimens in women with stress incontinence.     

Urinary incontinence in very young and mostly nulliparous women with a history of regular organised high-impact trampoline training: occurrence and risk factors

The aim of this study was to examine the occurrence of urinary incontinence (UI) in mostly nulliparous women with a history of regular organised trampoline training as adolescents and to identify possible predictors. Female trampolinists in Sweden with licence for trampolining between 1995–1999 (n = 305), with a median age of 21 (range 18–44) years answered retrospectively a validated questionnaire. Competition with double somersaults had been performed by 85 women, the “competition group” (CG), while 220 women comprised the “recreational group” (RG). Of the trampolinists with UI during trampolining, 76% continued to leak. In CG, 57% and, in RG, 48% reported current UI. Strong predictors for UI were inability to interrupt micturition (p < 0.001) and constipation (p = 0.007). Training factors such as frequency/week × years of trampolining (p < 0.001) and years of trampolining after menarche increased the risk of UI (p < 0.001). The prevalence of current UI was higher in ex-trampolinists than in normals (p < 0.001), and hence the negative effects of trampolining cannot be ruled out.     

Self-perceived natural history of pelvic organ prolapse described by women presenting for treatment

Introduction and hypothesis  This study aimed to describe the self-perceived natural history of pelvic organ prolapse (POP) in women seeking care. Methods  Women presenting to a university-based urogynecology clinic for POP (n = 107) completed a questionnaire including questions about how and when their prolapse was discovered. A urogynecologic examination including the pelvic organ prolapse quantification (POP-Q) was also performed. Results  Forty-eight percent of these women sought medical attention “immediately” after discovering a bulge. The median time to seek care was 4 months (range from 1 month to 45 years). Twenty-six percent associated their prolapse with a specific event (e.g., moving furniture or pushing a car). POP was self-discovered by 76% (81/107) of women. Self-discovered prolapses were larger than those diagnosed by physicians (Ba +1.3 vs 0.1 cm, P = .03, respectively). Conclusions  Women seek medical advice within months of discovering their prolapse. Self-discovery is associated with higher stage prolapse than prolapse diagnosed by health care providers.     

A Retrospective Comparison of Abdominal Sacrocolpopexy with Burch Colposuspension versus Sacrospinous Fixation with Transvaginal Needle Suspension for the Management of Vaginal Vault Prolapse and Coexisting Stress Incontinence

The objective of this study was to compare the surgical outcome of abdominal sacrocolpopexy and Burch colposuspension with sacrospinous fixation and transvaginal needle suspension in the management of vaginal vault prolapse and coexisting stress incontinence. One hundred and seventeen women with vaginal vault prolapse and coexisting stress incontinence were surgically managed over a 7-year period. The first 61 consecutive women who underwent sacrospinous fixation and transvaginal needle suspension comprised the vaginal group, and the following 56 consecutive women who underwent abdominal sacrocolpopexy and Burch colposuspension comprised the abdominal group. Office records were reviewed to assess the presence of recurrent prolapse and urinary incontinence during postoperative follow-up. Objective follow-up was available for 101 women. Mean duration of follow-up was 24.0 ± 15 months for the vaginal group, and 23.1 ± 12.6 months for the abdominal group. The incidence of recurrent prolapse to or beyond the hymen (33% vs. 19%, P = 0.0505) and lower urinary tract symptoms (26% vs. 13%, P = 0.0506) were significantly higher in the vaginal group than in the abdominal group. Our data suggest that the combined abdominal approach has a lower incidence of recurrent prolapse and lower urinary tract symptoms than the combined vaginal approach in managing vaginal vault prolapse and coexisting stress incontinence.     

Stress urinary incontinence and counseling and practice of pelvic floor exercises postpartum in low-income Hispanic women

The purpose of the study was to provide estimates of stress urinary incontinence (SUI) and practice of pelvic floor muscle training (PFMT) postpartum as well as counseling during and after pregnancy among Hispanic women. Two hundred Hispanic women were surveyed 6 months postpartum. Twenty-three percent had SUI with onset primarily during pregnancy (70%). Only 20% had received information regarding SUI and PFMT during pregnancy or postpartum. Most women not counseled wished they were (81%). Less counseling occurred among Hispanic women with lower levels of education (odds ratio [OR] = .39; 95% confidence interval [CI] = 0.19–0.82; p = 0.02) and those whose primary language was Spanish (OR = .36; 95% CI = 0.15–0.87; p = 0.02), while higher rates occurred among women with a forceps delivery (OR = 2.94; 95% CI = 1.06–7.78; p = 0.03). Fifty-seven percent of women counseled practiced the exercises. Primary reasons for noncompliance were belief that PFMT would not help (47%), and not understanding the instructions (39%). SUI and PFMT counseling is low among Hispanic women. Most women desire such information, and improvement in performance of PFMT among this group is possible. An erratum to this article can be found at
