  • Purpose: We studied the efficacy of shortening the pre-implanted suburethral tape in patients with recurrent urodynamic stress incontinence after a TVT operation.
  • Materials And Methods: A total of 14 women, including 6 with ISD, were treated for recurrent urodynamic stress incontinence after the initial TVT operation by performing the shortening procedure under local anesthesia. Urodynamics, a 1-hour pad test, introital ultrasonography of the urethra and a cotton swab test were done before the procedure and 1 year postoperatively.
  • Results: All 14 patients completed the shortening procedure. Mean patient age was 47.2 years (range 43 to 66). Mean time between initial TVT and the shortening procedure was 4 months (range 3 to 14). Ten patients (71.4%) were objectively cured and treatment failed in 4 (2 with ISD and 2 with a fixed urethra). Mean operative time was 17 minutes (range 10 to 25). No intraoperative surgical complications were observed. The 1-hour pad test showed a decrease from a median of 9.0 gm to 1.0. Median postoperative hospital stay was 1 day (range 1 to 4). Spontaneous voiding with adequate post-void residual urine was noted in all patients before discharge home.
  • Conclusions: Shortening a pre-implanted TVT tape for the treatment of recurrent urodynamic stress incontinence is a safe, effective and minimally invasive option requiring only a short hospital stay. However, ISD and an immobile urethra seem to be risk factors for failure. Long-term followup is needed to determine if this surgery achieves long-lasting results.

  • Editorial Comment
    The authors describe a method to address recurrent urinary incontinence after failed TVT by transvaginal plication of the in situ TVT tape. The authors managed to objectively cure 10 out of the 14 patients (71.4%) with this maneuver while 4 continued with recurrent stress incontinence.
    Addressing of recurrent urinary incontinence after TVT has been a topic of discussion in the literature. The above method as described appears to be quite technically facile with a very reasonable salvage success rate. The authors, while performing the transvaginal procedure, did not have any difficulty in locating the in situ sling. Secondary to the actual nature of the TVT procedure, the in place tightening of sutures cannot be performed as described by Choe (1). Repeat transvaginal tape (2) may be considered but carries with it the duplicate expense for the repeat tape. Though multiple options exist for the failed TVT (including repeat TVT procedure, suburethral sling using an alternative material, versus injectable) this procedure appears to be inexpensive, straight forward, with an acceptable level of success.
