Detrusor overactivity does not predict outcome of sacral neuromodulation test stimulation

The aim of this study is to determine if urodynamic findings in patients with urge incontinence predicts response to sacral neuromodulation test stimulation. One hundred four patients with refractory urinary urge incontinence who had undergone sacral neuromodulation test stimulation were retrospectively reviewed. Pre- and post-test stimulation incontinence parameters and pelvic floor muscle (PFM) contraction strength was documented. Urodynamics were reviewed on all patients, and the presence or absence of detrusor overactivity (DO) was noted. Patients were then divided into two groups: responders to the test stimulation and non-responders. A positive response was considered to be a ≥50% improvement in the number of incontinent episodes per day (IE/day) and/or pad weight with test stimulation. Of the 104 patients evaluated, 64% (N = 67) responded to the test stimulation, while 36% (N = 37) were non-responders. The mean age was 59.7 and 67.0 among responders and non-responders (p = .01). There was a significant difference in the number of IE/day between non-responders and responders (p = .02). There was no relationship found between the presence or absence of DO and the likelihood for test stimulation success, patient demographics or pre test stimulation incontinence variables. Our study provides no statistically significant evidence that the presence or absence of DO on urodynamics predicts a response to sacral neuromodulation test stimulation. An important finding, however, was that patients without demonstrable DO on urodynamics may still have a positive response to sacral neuromodulation.

Validation of a Spanish version of the Pelvic Organ Prolapse Incontinence Sexual Questionnaire

OBJECTIVE To develop a validated Spanish version of the Pelvic Organ Prolapse Incontinence Sexual Questionnaire (PISQ). METHODS The PISQ is a previously described validated and reliable questionnaire. We used a back-translation method to develop a Spanish-language version. Twenty-six bilingual patients with pelvic organ prolapse and/or urinary incontinence were randomized to complete either the original English version or the final Spanish version of the PISQ first, followed by the other questionnaire. Scores of the two versions were compared. Paired t test for total PISQ and its three domain scores and Wilcoxon signed rank test for each item assessed the bias between the two equivalent versions. Agreement between the two versions was assessed by weighted κ statistics, with 95% confidence intervals for each item. P values of .05 or less were considered significant, and κ values of .75 or greater were considered to indicate good agreement. RESULTS English and Spanish versions demonstrated no differences for each of the factors and total scores (P = .15, .83, .28, and .56, respectively). Wilcoxon signed rank test demonstrated that one item was answered differently in the English and Spanish versions. Good agreement between Spanish and English versions in 30 of the 31 items was demonstrated by weighted κ statistics. Overall, 72% of women scored both versions of the questionnaire equivalently. CONCLUSIONS We have developed a validated and reliable Spanish questionnaire to evaluate sexual functioning in Spanish-speaking patients with pelvic organ prolapse and/or urinary incontinence.

Transvaginal endoscopic removal of eroded mesh after Abdominal sacral colpopexy

BACKGROUND: Abdominal sacral colpopexy with permanent mesh has become the preferred abdominal technique for correcting posthysterectomy vaginal vault prolapse. Although rare, mesh erosion after sacral colpopexy is often challenging to manage. We report on 3 cases of mesh erosion after abdominal sacral colpopexy managed by transvaginal endoscopic removal of the mesh. CASES: The cases involve patients who underwent an abdominal sacral colpopexy and had vaginal mesh erosions within 3 years of their surgeries. Conservative and traditional transvaginal techniques failed, and the patients continued to complain of vaginal discharge. All patients underwent transvaginal endoscopic removal of the mesh and are cured of their chronic discharges. CONCLUSION: Transvaginal endoscopic removal is an effective, minimally invasive option for removal of eroded mesh after abdominal sacral colpopexy.

ORAL PRESENTATION 22: Neuropathic Injury to the Levator Ani Occurs in 1 in 4 Primiparous Women

OBJECTIVE We measured levator ani neuromuscular function before and after first delivery to identify the location, timing, and mechanism of injury. STUDY DESIGN Fifty-eight primiparous women underwent electromyographic examination of the levator ani antepartum at 6 weeks and 6 months after the delivery. Antepartum turns/amplitude data were pooled to create a normal range. We calculated each womans percentage of outliers from this range and assessed relationships between delivery and extent of injury. RESULTS At 6 weeks, 14 of 58 women (24.1%) had neuropathy, with 9 of those 14 women recovering by 6 months. At 6 months, 17 of 58 women (29.3%) were neuropathic, which included 12 new injuries. Women who had elective cesarean delivery had virtually no injury, but all other modes of delivery had similar injury rates. CONCLUSION Obstetric delivery is associated frequently with electromyographic evidence of neuropathic injury to the levator ani. The entire levator complex is at risk, and cesarean delivery while in labor is not protective.
