Transvaginal tape lysis for urinary obstruction after suburethral tape placement. When to do an immediate replacement?

To evaluate the interest and the indications of an immediate replacement of a suburethral tape after tape lysis for urinary obstruction is the aim of the study. From 2000 until 2007, a total of 22 patients underwent suburethral tape placement for stress urinary incontinence and developed thereafter a bladder outlet obstruction. These patients had a transvaginal tape lysis under local anesthesia. An immediate replacement of the tape was carried out in those patients who developed leakage under cough provocation test. Twelve patients (group 1) underwent a tape lysis and replacement. Ten patients (group 2) underwent a simple tape lysis. The two groups were demographically comparable. The continence rate was 100% in the two groups. The success rate defined by urodynamics was 75% for the first group and 80% for the second group. The success rate defined by the disappearance of the initial symptoms and improvement of the scores of the questionnaires was 75% for the first group and 90% for the second group.
