The tension-free pubourethral sling procedure using a small intestinal submucosa sling (e.g., Stratasis, Cook Urological, Spencer/IN, USA) is of interest to the reconstructive urologist because of its reported regenerative capabilities and lack of immunogenicity. We report a severe postoperative inflammatory complication 4 weeks after the procedure. Severe inflammation with abscess formation led to reconstructive surgery to deal with the secondary complications.
