There were 289 women with clinical and urodynamic diagnosis of primary stress urinary incontinence, stable bladder, and pelvic relaxation who underwent a single-stage surgical procedure because of incontinence and pelvic relaxation. Patients underwent one of three surgical procedures because of stress incontinence--anterior colporrhaphy, revised Pereyra procedure, or Burch retropubic urethropexy. Decisions with regard to the type of bladder neck suspension and the surgeon were made randomly with a randomization table. Each patient had a complete clinical and urodynamic evaluation before surgery and at 3 and 12 months after surgery. Cure rate as defined by strict clinical and urodynamic criteria was not significantly different among the three groups at the 3-month postsurgical evaluations; however, at the 12-month postsurgical evaluations, the cure rate among women who underwent Burch urethropexy (n = 101) was significantly higher than that of either Pereyra or anterior colporrhaphy (cure rates were 87%, 70%, and 69%, respectively; p less than 0.01). The Burch urethropexy was more effective than the Pereyra procedure or anterior colporrhaphy in the stabilization of the bladder base and resulted in a significantly better cure rate in women with primary stress urinary incontinence and pelvic relaxation.
