[Comparison of urodynamic findings before and after loop operations for recurrent incontinence]

30 patients with a recurrent stress incontinence were undergoing a dura-sling operation. The mean period of incontinence complaints up to the second surgery was 2.6 years. In the follow-up investigation the urodynamic parameters showed a significant improvement of the UCP, the urethral functional length and the DepQ. One year after surgery 86% of the women showed both a clinical and a urodynamic continence. A short term of urination disorders has to be considered in a part of the cases.
