Brief summary

The primary aim of this clinical trial is to compare the treatment success for two surgical procedures that are frequently used and have similar cure rates, yet have not been compared directly to each other in a large, rigorously conducted randomized trial. The secondary aims of the trial are to compare other outcomes for the two surgical procedures, including quality of life, sexual function, satisfaction with treatment outcomes, complications, and need for other treatment(s)after surgery. Follow-up will be a minimum of two years and up to four years.

Interventions

PROCEDUREBurch Modified Tanagho

The Burch colposuspension is a well-established procedure for surgically treating women with stress urinary incontinence. The Burch modified colposuspension suspends the anterior vaginal wall (at the level of the bladder neck) with permanent sutures tied to the iliopectineal ligament.

The fascial sling is also a well-established procedure for surgically treating women with stress urinary incontinence. The autologous sling procedure places a harvested strip of rectus fascia transvaginally at the level of the proximal urethra. The fascial strip is secured superiorly to the rectus fascia with permanent sutures
