Pubovaginal sling using cadaveric allograft fascia for the treatment of intrinsic sphincter deficiency
Purpose: Pubovaginal sling is the definitive management of female stress urinary incontinence due to intrinsic sphincter deficiency. Customarily, autologous fascia has been used, although synthetic material has its proponents. Harvesting autologous fascia at surgery is associated with postoperative discomfort, and synthetic material has a history of infection and erosion. To assess whether allograft fascia is free from these drawbacks, we retrospectively compared the outcome of women undergoing pubovaginal sling using either autologous or cadaveric allograft fascia. Materials and Methods: We reviewed our experience during the last 28 months with patients treated with the pubovaginal sling for intrinsic sphincter deficiency. All patients underwent preoperative video urodynamics. The outcome was assessed using the SEAPI scoring system. Special attention was devoted to local sling tolerance. Operative time and length of hospital stay were compared between patients with allograft and autograft pubovaginal sling. Results: A total of 92 women (mean age 60 years) underwent allograft (59) or autograft (33) pubovaginal sling. Preoperative parameters, such as percent of patients who had previous incontinence surgery, mean leak point pressure and SEAPI incontinence score, were similar in both populations. Mean followup was 11.5 months (range 1 to 28) for the overall population. The SEAPI scoring system showed that patients were markedly improved, with no significant difference between the allograft and autograft groups. Allograft and autograft pubovaginal slings were equally well tolerated, and no infection or erosion was encountered. Mean operative time and hospital stay were significantly shorter when using allograft compared to autograft fascia. Conclusions: The success rates of allograft and autograft pubovaginal sling were equally high, and no complications related to the cadaveric origin of the allograft fascia were observed. Allograft pubovaginal sling was well tolerated, and its use significantly shortened operative time and hospital stay.
