Pubovaginal sling using Duraderm graft: intermediate follow-up and patient satisfaction

To assess outcome and patient satisfaction utilizing Duraderm allograft as sling material.

Twenty five patients undergoing the Duraderm sling procedure were evaluated by pelvic examination, post-void residual urine, and multi-channel urodynamics. Follow-up included repeat examination, stress test, and chart review. Patient satisfaction was assessed by phone interview with an independent examiner. Outcome was defined as dry (no leaking at all and patient perception of satisfaction), improved (minimal leak requiring < or =1 pad daily and patient perception of satisfaction), or failure.

Average age was 62.0 years (30-83); average daily preoperative pad usage was 3.5 (2-8). Duraderm allograft measuring 2 x 12 cm was used. Mean postoperative catheter time was 7.7 days (3-37 days). At 6 months, 17/25 (68%) were dry, 6 (24%) improved, and 2 (8%) failed. Mean intermediate follow-up at 14.8 months (8-23 months) revealed 8/25 (32%) patients were dry, 9 (36%) were improved, and 8 (32%) failed Duraderm sling. Mean pad use after surgery was 1.4 (0-6). Of the 25, 19 (76%) were satisfied with the surgical outcome, 17 (68%) noted they would have surgery again, and 17 (68%) would recommend the procedure.

Initial results of pubovaginal sling using Duraderm graft are satisfactory; however, longer term follow-up is disappointing. Graft degeneration previously described after utilization of cadaveric fascia lata may be possible following implantation of cadaveric dermis.
