Can urethral mobility be assessed using the pelvic organ prolapse quantification system? An analysis of the correlation between point Aa and Q-tip angle in varying stages of prolapse.

OBJECTIVES: To determine whether the Pelvic Organ Prolapse-Quantification (POP-Q) system can be used as a replacement for Q-tip testing to assess urethral mobility in women. METHODS: We performed a retrospective review of a clinical database of 1490 patients presenting to a urogynecology clinic. The evaluation included both Q-tip straining angle and POP-Q examination. Urethral hypermobility was defined by the Q-tip test as a straining angle of 30 degrees or greater relative to the horizontal. The correlation between point Aa of the POP-Q system and the maximal Q-tip straining angle was determined using the Spearman correlation coefficient. RESULTS: The mean age of the 1490 patients was 59.5 +/- 13.1 years; the median parity was 2. A total of 62 patients (4.2%) reported prior surgery for incontinence or prolapse. The mean Q-tip straining angle was 44.7 degrees +/- 21.8 degrees. The point Aa values were +3 to -3 cm (median -2). The correlation coefficient between the Q-tip straining angle and point Aa was 0.54 (P <0.001). Urethral hypermobility was observed in 93.3% patients with stage 3 prolapse, 92.5% with stage 2, 88.9% with stage 1, and 55.8% with stage 0. Only in patients with stage 4 prolapse was urethral hypermobility observed 100% of the time. CONCLUSIONS: The correlation between point Aa of the POP-Q and the Q-tip straining angle was moderately strong when analyzed across all degrees of prolapse. However, urethral hypermobility could not be reliably predicted from POP-Q measurement alone. Therefore, the Q-tip test remains an essential part of the urogynecologic evaluation.

Determinants of vaginal length.

OBJECTIVE: The purpose of this study was to describe quantitatively the associations between total vaginal length and demographic, historic, and physical characteristics. STUDY DESIGN: At 2 clinical sites, patients completed a standardized questionnaire and physical examination. Bivariate correlations explored relationships between total vaginal length and demographic, historic, and examination variables. Significant variables were evaluated with a multivariate linear regression model. RESULTS: The study included 3247 women. Hysterectomy and pelvic reconstructive surgery contribute 0.63 cm and 0.22 cm, respectively, to total vaginal length shortening; 10 years of age decreases total vaginal length by 0.08 cm. One meter of height and 10 kg of weight increases total vaginal length by 0.09 cm and 0.02 cm, respectively. Menopause is associated with a shortening of total vaginal length by 0.17 cm. CONCLUSION: Although there appears to be statistically significant associations between total vaginal length and the aforementioned factors, the impact is unlikely to be clinically significant.

The correlation of urethral mobility and point Aa of the pelvic organ prolapse quantification system before and after surgery.

OBJECTIVE: The purpose of the study was to determine the effects of pelvic floor surgery on Q-tip angle and point Aa of the pelvic organ prolapse quantification system. STUDY DESIGN: A clinical database was used for this retrospective review of Q-tip and prolapse measurements before and after pelvic floor surgery. Subanalyses of isolated bladder neck and prolapse surgeries were also performed. Correlations between Q-tip and point Aa were assessed with Pearson and Spearman coefficients and the Z statistic. RESULTS: Correlations between Q-tip and point Aa for all 350 women were not significantly different before and after the operation (r = 0.45 vs 0.49; P = .50). Subanalysis of the bladder neck-only group demonstrated similarly fair correlations (r = 0.26 vs 0.31; P = .71; n = 94). The prolapse-only group demonstrated better overall correlation without significant differences before and after the operation (r = 0.78 vs 0.51; P = .10; n = 26). CONCLUSION: Point Aa does not reflect bladder neck mobility accurately as measured by the Q-tip angle after surgical restoration of the pelvic anatomy.

Vaginal paravaginal repair with porcine dermal reinforcement: correction of advanced anterior vaginal prolapse.

OBJECTIVE: The objective of the study was to determine the efficacy of the vaginal paravaginal repair using porcine dermal graft reinforcement for the correction of advanced anterior vaginal prolapse. STUDY DESIGN: One hundred eleven women underwent reinforced vaginal paravaginal repair between September 2001 and January 2004 and met our inclusion criteria. Postoperatively patients were evaluated at 6 weeks, 6 months, and yearly thereafter. Objective cure was defined as point Ba -1 or less. RESULTS: Eighty-nine of the 111 (80%) patients were available for follow-up. Mean age of patients was 59.5 +/- 11.6 years (range 26 to 82), mean body mass index was 29 +/- 5.5 (range 20 to 44), and median parity was 3 (range 0 to 15). Mean follow-up was 24 +/- 10.1 months (range 6 to 44) with minimum follow-up required for cure of 12 months. Overall cure rate was 78% (68 of 89). Data were analyzed using the Wilcoxon rank test. CONCLUSION: The reinforced vaginal paravaginal repair procedure is safe and effective for correction of advanced anterior vaginal prolapse.

Elevated postvoid residual in women with pelvic floor disorders: prevalence and associated risk factors.

A retrospective case-control study was designed to assess risks for elevated post void residual (PVR) in women with pelvic floor disorders. The 1,399 women underwent evaluation including standardized questionnaire, examination, and catheterized PVR. Elevated PVR was defined as > or =100 ml and anterior and apical prolapse was defined as at or beyond the hymen. Overall, the prevalence of elevated PVR was 11%. After matching, the absence of stress incontinence symptoms (OR 0.55, CI 0.33-0.92), the symptoms of vaginal bulge (OR 2.19, CI 1.38-3.48), pelvic pressure (OR 1.79, CI 1.14-2.86), urinary splinting (OR 2.89, CI 1.24-6.74), and presence of prolapse (OR 2.60 CI 1.62-4.18) were significantly associated with an elevated PVR. Only prolapse (OR 1.96 CI 1.37-2.79) maintained a significant association after multivariate analysis. Symptoms alone do not predict which women may have an elevated PVR, but the finding of prolapse at or beyond the hymen is associated with incomplete emptying. Elevated post void residuals cannot be predicted based on symptoms alone; however, prolapse beyond the hymen may help identify women with incomplete bladder emptying.

Factors associated with incontinence frequency in a surgical cohort of stress incontinent women.

OBJECTIVE: The aim of this study was to identify factors associated with urinary incontinence severity at baseline in women undergoing surgery for stress incontinence. STUDY DESIGN: Baseline data were obtained from 650 women (age 28 to 81 years) with stress incontinence participating in a randomized surgical trial. Severity of incontinence was defined by the mean number of incontinence episodes per day recorded in a 3-day bladder diary. The relationships between severity and several baseline variables were examined, including demographics, medical, obstetric, and gynecologic history, body mass index, smoking status, Q-tip displacement, and Pelvic Organ Prolapse Quantification stage (POP-Q). RESULTS: In a multivariable model, severity of incontinence was positively associated with body mass index (P = .0003) and current smoking (P = .01), and negatively associated with prolapse stage (P < .0001) and Q-tip displacement (P = .042). CONCLUSION: Incontinence severity in a surgical population was independently associated with 2 modifiable factors, obesity and tobacco use, as well as pelvic support.

Suburethral sling materials: best outcome with autologous tissue.

OBJECTIVE: This study was undertaken to assess the outcome of suburethral slings by type of sling material. STUDY DESIGN: A retrospective review of women who underwent a suburethral sling between January 1997 and January 2003 with autograft, allograft or xenograft materials. Objective failure was defined as urinary leakage with cough stress testing at any time after 3 months, postoperatively. Objective cure was defined as no leakage with a standing cough stress test with at least 200 mL bladder volume at a minimum of 12 months postoperatively. Data were analyzed using Student t, Wilcoxon rank sum, and Kaplan-Meier survival tests. RESULTS: A total of 241 women were included in this study: 78 received autograft, 80 received allograft, and 83 received xenograft. Objective failure was 36% and 46% for allograft and xenograft, respectively compared with 13% for autograft (P < .001). CONCLUSION: Autograft has a significantly higher cure rate when used for suburethral slings.

Predictive value of prolapse symptoms: a large database study.

We sought to describe the relationship between patient symptoms and pelvic organ prolapse (POP) and report the sensitivity, specificity, and positive and negative predictive value of these POP symptoms. Two urologists and four urogynecologists developed a standardized pelvic floor questionnaire based on face validation for use at three female pelvic floor disorder clinics. Specific questions related to prolapse included questions on urinary splinting, digital assistance for defecation, and a bulge per vagina. Prolapse was assessed with the standardized Pelvic Organ Prolapse Quantitative (POP-Q) terminology. The analysis included 1912 women. Urinary splinting was uncommon (< 10%) when Ba < 0, but ranged between 23 and 36% for stage III and IV Ba prolapse. Digital assistance was equally common in stage II Bp prolapse (21-38%) and stage III-IV Bp prolapse (26-29%). Only 6-11% of women with stage 0 or I POP reported symptoms of bulge, but with stage II it increased to 77%. Urinary splinting is 97% specific for anterior prolapse. The report of a bulge has an 81% positive predictive value and a 76% negative predictive value. Very few patients without anterior prolapse will report urinary splinting. Digital assistance for fecal evacuation is no more common with massive posterior prolapse than with moderate posterior prolapse. Patient report of a bulge is a valuable screening tool for POP and should prompt a careful exam.

Anterior vaginal wall hammock with fascia lata for the correction of stage 2 or greater anterior vaginal compartment relaxation.

PURPOSE: We determined the efficacy of the anterior vaginal wall hammock (AVWH) using fascia lata for the correction of anterior vaginal compartment relaxation. MATERIALS AND METHODS: A total of 58 patients with stage 2 or greater anterior vaginal compartment relaxation underwent an AVWH procedure with autologous or allograft fascia lata from June 1998 to March 2001. Patients were evaluated preoperatively with a history and pelvic organ prolapse quantitative examination. Postoperatively patients were evaluated at 6 weeks, 6 months and yearly thereafter with pelvic organ prolapse quantitative staging of the anterior, middle and posterior compartments. Objective cure was defined as stage 0 or 1 relaxation. Subjective cure was defined as no symptoms of pelvic pressure or a vaginal bulge. RESULTS: Of the 69 (89%) patients who underwent surgery 58 were available for followup. Median age of the population was 61.9 years and median followup was 24.7 months (range 12 to 57). There were 11 objective failures (19%) in the anterior compartment, of which 1 (2%) was symptomatic. Two patients (4%) had enteroceles that required surgical correction. Of the patients 16 (28%) had new onset or worsening stage 2 posterior relaxation at a median of 15.2 months postoperatively, including 7 (12%) who were symptomatic and underwent subsequent repair. CONCLUSION: The AVWH procedure with fascia lata is safe and effective for correcting stage 2 or greater anterior compartment relaxation. The whole pelvic floor must be evaluated and repaired to minimize the progression of prolapse of the middle and posterior compartments.
