Anal incontinence (AI) is a significant problem that causes social and hygienic inconvenience. The true prevalence of AI is difficult to estimate due to inconsistencies in research methods, but larger studies suggest a rate of 2-6% for incontinence to stool. There is a significant association between sonographically detected anal sphincter defects and symptoms of AI. The intrapartum factors most consistently associated with a higher risk of AI include: forceps delivery, third or fourth degree tears, and length of the second stage of labor. Fetal weight of > 4,000 g is also associated with AI. Repair of the sphincter can be performed in either an overlapping or an end-to-end fashion, with similar results for both methods. The role of cesarean delivery for the prevention of AI remains unclear, and further study should be devoted to this question.

The objective of this study was to review our experience with pessary use for advanced pelvic organ prolapse. Charts of patients treated for Stage III and IV prolapse were reviewed. Comparisons were made between patients who tried or refused pessary use. A successful trial of pessary was defined by continued use; a failed trial was defined by a patient's discontinued use. Thirty-two patients tried a pessary; 45 refused. Patients who refused a pessary were younger, had lesser degree of prolapse, and more often had urinary incontinence. Most patients (62.5%) continued pessary use and avoided surgery. Unsuccessful trial of pessary resorting to surgery included four patients (33%) with unwillingness to maintain, three patients (25%) with inability to retain and two patients (17%) with vaginal erosion and/or discharge. Our findings suggest that pessary use is an acceptable first-line option for treatment of advanced pelvic organ prolapse.

OBJECTIVE: Using quantitative sensory testing and a validated questionnaire, we investigated the role of pudendal nerve integrity in sexual function among women. STUDY DESIGN: Participants completed the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ). Vibratory and pressure thresholds were measured at the S2 dermatome reflecting pudendal nerve distribution. RESULTS: A total of 56 women enrolled; 29 (51.8%) were asymptomatic and 27 (48.2%) had 1 or more forms of female sexual dysfunction (total sexual dysfunction) including: desire disorder 16.1%, arousal disorder 26.8%, orgasmic disorder 25%, and pain disorder 12.5%. Age, parity, menopausal status, and body mass index were similar between groups. PISQ scores were lower in symptomatic subjects compared with controls (P < .001). Decreased tactile sensation was found at the clitoris for women with total sexual dysfunction, desire disorder, and arousal disorder. Women with arousal disorder also had decreased tactile sensation at the perineum. CONCLUSION: Pudendal nerve integrity may play a role in female sexual dysfunction.

Graft augmentation for repair of recurrent pelvic organ prolapse is commonly used in reconstructive pelvic surgery. The reported complications are mainly late onset. We report a case of early-onset inflammatory reaction following bovine pericardium graft augmentation for posterior vaginal wall defect repair. A 49-year-old presented with a recurrent and symptomatic posterior vaginal wall defect. She underwent an uneventful site-specific repair and bovine graft augmentation. Her early postoperative course was complicated by inflammatory response to the graft presenting as intense pelvic floor spasm and urinary retention. The condition was managed conservatively and resolved subsequently. One year later, the patient continues to be asymptomatic. Transient intense pelvic floor spasm and urinary retention can be the result of inflammatory reaction following graft augmentation with bovine pericardium for posterior vaginal wall defect repair.

The aim of this study was to investigate the effects of age, menopause, and comorbidities on neurological function of the female genitalia using a noninvasive, validated technique. In all, 58 consecutive women were enrolled in the study. Biothesiometry was performed at five genital sites and one peripheral site with S2 dermatome distribution. Kruskal-Wallis one-way ANOVA on ranks was used to evaluate the relationship between age and vibratory sensation. Bivariate and regressional analyses were performed to evaluate the effects of age, menopause and comorbidities on genital sensation. The mean age was 44.6+14.8 y (range 20-78 y). Vibration thresholds increased with advancing age at all six sites. Multilinear regression analysis indicated that menopause and increasing age negatively affect sensation. History of herniated lumbar disc, vaginal delivery, and diabetes variably affected genital sensation. There is a significant increase in vibration thresholds (indicating worsening neurological function) in women as they age and undergo menopause. Biothesiometry is a technique for evaluating genital neurological function in women with coexisting morbidities.

This study aimed to determine whether preoperative pessary reduction of anterior vaginal wall prolapse in patients with elevated postvoid residual (PVR) volumes relieves urinary retention, and if reconstructive pelvic surgery in these patients cures urinary retention. The records of all women with symptomatic anterior vaginal wall and urinary retention (PVR >or=100 cc) who underwent evaluation and surgical repair of the anterior vaginal wall at our institution between 1996 and 1999 were retrospectively reviewed. All patients underwent a detailed urogynecologic and urodynamic evaluation and had a pessary trial prior to surgery. Cure of urinary retention was defined as PVR <100 cc at 3 months postoperatively. Sensitivity, specificity, positive and negative predictive values for pessary reduction testing were calculated. Twenty-four patients met the inclusion criteria. Two patients (8%) had stage 2, eleven (46%) stage 3, and eleven (46%) stage 4 anterior vaginal wall prolapse. Preoperatively, the use of pessary was associated with relief of urinary retention in 75% patients. In predicting postoperative cure of urinary retention, pessary testing had a sensitivity of 89%, specificity of 80%, positive predictive value of 94%, and negative predictive value of 67%. Nineteen of 24 patients had a PVR <100 cc postoperatively, indicating a 79% cure rate for urinary retention. In women with symptomatic anterior vaginal wall prolapse and urinary retention, use of a pessary is associated with relief of retention in the majority of patients. Furthermore, pessary reduction testing has good sensitivity, specificity, and positive predictive value for postoperative voiding function.

We describe our long-term outcome for patients with genuine stress incontinence (GSI) and urethral hypermobility using a modified vaginal wall patch sling technique. Fifty-three patients were studied. Preoperatively, all patients had a positive standing stress test and urethral hypermobility on Q-tip testing. On urodynamics, all patients had absence of detrusor contractions on subtracted cystometry. The mean age of the patients was 45+10.2 years. Forty-four patients demonstrated complete symptomatic and urodynamic improvement. Five patients had a noticeable failure observed within the first 12 months of follow up and four patients developed later recurrence despite initial success. The overall success rate after 5 years of follow up was 83% (n=44/53). The modified vaginal wall patch sling technique appears to have a good long-term success rate with low operative morbidity and minimal postoperative voiding dysfunction. The patch sling can be used as a first-line surgical approach for GSI with urethral hypermobility and be combined with other vaginal surgery.

BACKGROUND:Vulvar arteriovenous hemangioma is a rare pathologic lesion that can have a unique clinical presentation. One manifestation of this lesion has not previously been described in the literature. CASE/METHODS:A painful vulvar mass occurred in a healthy woman, with cyclic perineal discomfort and enlargement of the mass with menses. There was no obvious lesion on the skin. Excisional biopsy and groin exploration revealed a vascular lesion in the subcutaneous layer, consistent with arteriovenous hemangioma. The mass was successfully treated by excision, and the patient was asymptomatic 12 months later. CONCLUSION/CONCLUSIONS:Surgical exploration should be considered when a definitive diagnosis of a symptomatic vulvar mass is uncertain. In this case, excision of the mass allowed diagnosis and definitive treatment.
