The margin to incontinence after three types of operation for stress incontinence

Abstract

Three of the most widely used operations for stress incontinence--urethropexy ad modum Marshall-Marchetti-Krantz, pubococcygeal repair according to Ingelman-Sundberg and the Zoedler sling operation--were studied concerning urodynamic results. Simultaneous urethrocystometry with recording of the urethral pressure profile was used to quantify postoperative continence. The urethral pressure profile at rest, the transmission of pressure from abdomen to urethra and the efficiency of the smooth muscle in the urethral wall and its supporting tissues in a dynamic situation were compared with preoperative findings. Equally good results were obtained with the Marshall-Marchetti-Krantz and the Ingelman-Sundberg operation, which improved pressure transmission.
