Urodynamic findings in women with pelvic organ prolapse and obstructive voiding symptoms.

摘要

OBJECTIVE: To determine whether obstructive voiding symptoms in women with advanced pelvic organ prolapse (POP) were associated with objective bladder outflow tract obstruction. METHODS: We reviewed preoperative data from patients with advanced POP who underwent surgical correction at the Department of Obstetrics and Gynecology, Carmel Medical Center, Haifa, Israel, between December 1, 2005, and November 30, 2007. Obstructive voiding symptoms were recorded from Pelvic Floor Distress Inventory-20 questionnaires. RESULTS: Of the 81 women aged 44-80 years who were included in the study, 40 (49.4%) reported incomplete bladder emptying preoperatively. There was no significant difference between these women and asymptomatic women in terms of demographic and clinical parameters such as age, parity, and stage of prolapse. Furthermore, there was no significant difference with regard to postvoid residual bladder volume (52.8 +/- 65.8 vs 41.6 +/- 41.2 mL), maximal (23.8 +/- 11 vs 21.9 +/- 9.6 mL/second) and average (10.3 +/- 6.2 vs 9.3 +/- 4 mL/second) urinary flow velocities, prevalence of increased postvoid residual volume (10.0% vs 4.8%), or obstructive urinary flow (17.5% vs 7.3%). CONCLUSION: Almost half of all women with advanced POP experienced incomplete bladder emptying; however, this symptom did not correlate with objective urodynamic bladder outflow tract obstruction.
