Autologous fascial slings remain viable at long-term follow-up: a post cystectomy case report

Abstract

Background Autologous fascial slings (AFS) have been used for a very long time in the treatment of female stress urinary incontinence, but the introduction of synthetic mesh slings placed either retropubicallyor trans-obturator has decreased the need to harvest the autologous rectus muscle fascia, thus reducing invasiveness and operative time. However AFS are still indicated in complicated cases and re-interventions, and the FDA has underlined safety concerns over the use of surgical meshes for the transvaginal repair of prolapsed pelvic organs. Case presentation A 76-year-old woman with muscle-invasivebladder cancer underwent radical cystectomy 16 years after retropubic positioning of an autologous rectus muscle fascial sling for SUI, with complete symptom resolution. The sling was easily identified and removed en bloc with the bladder and urethra, providing an opportunity to histologicallyevaluate the autologous fascial graft after its long permanence in the new position. Histopathological examination demonstrated increased fibroblastic proliferation and formation of capillaries. A slight separation and an increased waviness of the connective fibers were both evident. An increased vascularity was also apparent, including transverse vessels, with clusters of vessels. A relative inflammatory reaction was present in over 300 cells/10 HPF. All these characteristics indicated viable connective tissue. Conclusions AFS remain a valuable surgical option for both primary and recurrent SUI in women, showing high cure rates and low complications in the long-term. The present case, to the best of our knowledge, presents the longest follow-up period of an autologous rectus muscle fascia placed retropubically and its histological evaluation documents characteristics which support its mechanical strength and viability.
