Use of ultrasound in the clinical evaluation of women following colpocleisis

Objective To assess the role of transperineal ultrasound in the postoperative evaluation of patients undergoing colpocleisis. Methods Patients who underwent colpocleisis between July 2009 and January 2011 completed the Pelvic Floor Distress Inventory questionnaire (PFDI-20) and underwent pelvic organ prolapse quantification (POP-Q) examination and four-dimensional (4D) transperineal ultrasound. Volumes were analyzed offline for assessment of pelvic organ descent, levator hiatal dimensions, levator avulsion trauma and the location of the colpocleisis scar. Results The study included 16 women, of mean ± SD age 75.7 ± 2.9 years, median body mass index 28 (range, 21-32) kg/m² and median parity 2 (range, 0-5); one woman was nulliparous. Nine (56.2%) women were posthysterectomy. The median interval from surgery to ultrasound examination was 6.5 (range, 2-19) months. Most patients did not have symptoms of prolapse. The median Pelvic Organ Prolapse Distress Inventory (POPDI-6) score was 37.5 (range, 0-75) and the median postoperative clinical POP-Q stage was 1 (range, 0-2). Ultrasound demonstrated clear visualization in all patients. Ten had avulsion defects (six were bilateral). Ultrasound estimated greater prolapse descent for all compartments when compared with the clinical examination. However, this difference was significant for anterior and posterior descent, but not for apical descent. In two women urethral diverticulum was detected on ultrasound; it was neither symptomatic nor clinically apparent. Conclusions 4D transperineal ultrasound seems to be a potentially effective tool for the evaluation of vaginal anatomic and functional changes following colpocleisis surgery. Future investigation of the association between ultrasound findings and patients' subjective symptoms in a larger cohort is warranted.
