    Abstract:
    OBJECTIVE: The objective of the study was to determine the incidence of ureteral obstruction during vaginal surgery for pelvic organ prolapse and the accuracy and efficacy of intraoperative cystoscopy. STUDY DESIGN: The study was a retrospective review of 700 consecutive patients who underwent vaginal surgery for anterior and/or apical pelvic organ prolapse with universal intraoperative cystoscopy. RESULTS: Thirty-seven patients (5.3%) had no spillage of dye from 1 or both ureters intraoperatively. The false-positive and negative cystoscopy rates were 0.4% and 0.3%, respectively. Thus, the true incidence of intraoperative ureteral obstruction was 5.1%. Intraoperative cystoscopy was accurate in 99.3% of cases, with a sensitivity and specificity of 94.4% and 99.5%, respectively. Suture removal relieved ureteral obstruction in 88% of cases. Six subjects (0.9%) had true ureteral injuries. CONCLUSION: Vaginal surgery for anterior and/or apical pelvic organ prolapse is associated with an intraoperative ureteral obstruction rate of 5.1%. Intraoperative cystoscopy accurately detects ureteral obstruction and allows for relief of obstruction in the majority of cases.
