The efficacy of laparoscopic mesh colposuspension: results of a prospective controlled study.

Abstract

To investigate the efficacy of laparoscopic mesh colposuspension as an equivalent approach to the 'gold standard' open Burch colposuspension. A prospective controlled study of laparoscopic mesh colposuspension was conducted over 2 years; 87 patients with genuine stress incontinence (GSI) were recruited. The preoperative evaluation included a history, examination, midstream urine analysis, urinary voiding diary, a Urilos pad test, and twin-channel subtracted cystometry, including urethral profilometry and measurement of the postvoid residual volume. The study included patients who had undergone previous incontinence surgery, but those with detrusor instability or neurogenic bladder were excluded. The patients were assessed at 6 weeks, 6 months and 1 year after surgery and then yearly thereafter. The urodynamic assessment was repeated 3 months after surgery. Forty-nine patients underwent laparoscopic colposuspension using Prolene mesh and titanium tacks to elevate the bladder neck, while 38 patients had open Burch colposuspension. There was no difference between the groups in age, parity, body mass index, menopausal status, medical history, previous bladder neck surgery and prolapse. At 6 weeks the cure rate was similarly high in the two groups (91% laparoscopic and 94% open). After a mean follow-up of 32 months, both groups showed a decline in efficacy, which was more marked in the laparoscopic group. Cure rates were 62% for laparoscopy and 79% for open surgery, and the improvement rates were 77% and 89%, respectively (P < 0.05). Laparoscopic colposuspension using a mesh and tacker technique reduces the technical difficulty and operating time of the endoscopic procedure, but the long-term cure rates are inferior to open Burch colposuspension.
