Prospective randomised controlled trial comparing laparoscopic and open colposuspension.
OBJECTIVE: To compare the efficacy, safety, complications, and short-term outcome of laparoscopic and open colposuspension in women with genuine stress incontinence. DESIGN: Randomised controlled trial. SETTING: Urogynaecology unit in a public hospital, Hong Kong. SUBJECTS AND METHODS: Ninety patients with urodynamically proven genuine stress incontinence. Forty-three patients were randomly allocated to receive open colposuspension and 47 to undergo laparoscopy. All patients had reassessment within 1 year of the operation. MAIN OUTCOME MEASURES: Objective and subjective measures and complication rates. RESULTS: There was no significant difference in the duration of stress incontinence, mean preoperative pad test results, or proportion with pre-existing detrusor instability. Among patients in the laparoscopic group, the mean operating time was significantly longer (42.0 minutes versus 29.3 minutes; P<0.0001), while the mean blood loss was significantly less (124.7 mL versus 326.9 mL; P=0.001). Subjective and objective success rates within 1 year were similar for patients in the open and laparoscopic groups (86.0% versus 80.9%; P=0.58, and 86.0% versus 85.1%; P=1.00, respectively). There was no significant difference in the rate of complications, including de novo detrusor instability and an obstructive voiding pattern, enterocele, or dyspareunia. CONCLUSION: Laparoscopic colposuspension is a feasible alternative to the open approach. The operating time is longer but the short-term cure rate is comparable with that of the open approach.
