Variables affecting maximum urethral closure pressure (MUCP) and abdominal leak point pressure (ALPP) measurements.

INTRODUCTION AND HYPOTHESIS: The relationship between pelvic floor muscles and measurements of urethral function is not well studied. It is not known whether adjusting for clinical, demographic and urodynamic parameters would improve the association between MUCP and ALPP. Our hypothesis was that pelvic floor muscle strength (PFMS) influences the relationship between MUCP and ALPP. METHODS: This was a retrospective study of women who underwent a complex urodynamic study with evaluation of MUCP and ALPP using ICD-9 codes with documentation of PFMS. RESULTS: Urodynamic stress incontinence was confirmed in 478 patients, of whom 323 had MUCP recorded and 263 had both MUCP and ALPP recorded. Women with higher PFMS had a higher MUCP. In regression analysis ALPP at 150 mL and MUCP were weakly associated (coefficient 0.43, 95% CI 0.08-0.78; p = 0.02), whereas ALPP at capacity and MUCP were moderately associated (coefficient 0.60, 95% CI 0.25-0.95; p < 0.001). CONCLUSIONS: This study showed that MUCP and ALPP at 150 mL were weakly associated and that this improved to a moderate association for ALPP at capacity. MUCP increased with increasing PFMS among women with stress urinary incontinence and decreased with increasing age. There was no evidence that ALPP was associated with PFMS or age. The relationship between MUCP and ALPP was unchanged when accounting for covariates of PFMS (age, parity, BMI, prior procedure, urethral mobility, bladder capacity, stage of cystocele, or stage of uterine or apical prolapse).

Symptomatic Epidermoid Cyst Presenting as a Paravaginal Mass.

BACKGROUND: Ischioanal fossa epidermoid cysts are uncommon masses of epithelial origin and are believed to be either congenital or the result of trauma. Surgical excision is preferred as opposed to incision and drainage because these masses may enlarge, recur, become infected, or undergo malignant transformation. CASE: This report describes a case of a 62-year-old woman who presented for evaluation of vaginal and perineal discomfort and fullness. Physical examination and computed tomography scan revealed a 7.1-cm cystic mass in the left ischioanal space. Transgluteal surgical excision was performed and pathology revealed an epidermoid cyst. The patient recovered with symptomatic improvement. CONCLUSIONS: This report demonstrates a rare case of ischioanal fossa epidermoid cyst. In cases of rectal masses, cystic lesions should be considered. Thorough physical examination, imaging studies, and proper surgical management of these masses can improve patient symptomatology, prevent recurrence, and also decrease the risk of malignant transformation.

Utility of antimüllerian hormone level obtained for infertility assessment for alerting to ovarian tumor.

BACKGROUND: Antimüllerian hormone is a marker of ovarian reserve and is now routinely measured in women seeking infertility treatment. CASE: A 42-year-old woman, gravida 1, abortus 1, presented with secondary infertility. Obtained originally for assessment of ovarian reserve, an antimüllerian hormone of more than 160 ng/mL raised suspicion for a granulosa cell tumor. A laparoscopic right salpingo-oophorectomy, pelvic washings, dilation and curettage, and peritoneal and omental biopsies were performed. A well-differentiated granulosa cell tumor confined to the right ovary was consistent with stage 1A disease. CONCLUSION: As the use of antimüllerian hormone becomes more common for ovarian reserve testing, providers need to maintain an awareness for neoplastic disease with abnormal values.
