The effect of retropubic urethropexy on detrusor stability.
A group of 86 women with genuine stress incontinence who underwent retropubic urethropexy were evaluated with both pre- and postoperative urodynamics. Twenty of these 86 women (23.3%) also had unstable detrusors preoperatively. Eleven of these 20 women (55%) had stable detrusors after retropubic urethropexy. Five of the 66 patients (7.6%) who had stable detrusors preoperatively were found to have unstable detrusors on postoperative urethrocystometry. The overall cure rate for women with detrusor instability and genuine stress incontinence was only 30%. Analysis of symptoms, previous anti-incontinence procedures, age, parity, and cystometric parameters revealed no differences between those women who had stable detrusors after retropubic urethropexy and those who remained unstable. Similarly, patients whose bladders became unstable after retropubic urethropexy could not be distinguished from those who remained stable. Patients undergoing retropubic urethropexy should understand the possibility that the operation may cause urinary incontinence due to detrusor instability even if it cures their genuine stress incontinence, and that if they have both genuine stress incontinence and detrusor instability, their chances for an operative cure of both conditions are low.
