Urodynamic and radiologic parameters before and after loop surgery for recurrent urinary stress incontinence.

In recent years, accurate preoperative diagnosis has been increasingly emphasized as an important therapeutic aspect of urinary incontinence in women. Forty patients suffering from recurrent stress incontinence underwent a dura-sling operation, i.e. loop surgery. The mean period od incontinence complaints prior to secondary surgery was 2.6 years. Follow-up urodynamic parameters revealed a slight improvement in urethral closure pressure (UCP) as well as significant improvement in functional urethral length and depression quotient. Radiologic investigations before and after sling surgery demonstrated good morphological results (angle beta). One year after surgery, 85% of the women had both clinical and urodynamic continence. Medium-term micturition complaints, however, have to be accepted in some of the patients.
