Abstract
The effect of abdomino-vaginal sling urethroplasty using lyodura slings, on the intravesical and intraurethral pressure was evaluated in 25 women with prolapse and stress incontinence. The investigations included a gynecological examination, urine and simultaneous urethrocystometry. Prior to the operation, all incontinent women had a negative urethral closure pressure at stress. After surgery all 25 patients reported continence, confirmed by positive urethral closure pressures. The urethral pressure at rest was significantly decreased in all patients 2 wk after operation but returned to the same preoperative value 1 yr after surgery. The functional and the absolute urethral lengths increased minimally after the operation.
