Repeat retrourethral transobturator sling in the management of recurrent postprostatectomy stress urinary incontinence after failed first male sling.

Abstract

A failure rate between 20% and 45.5% after retrourethral transobturator sling (RTS) is reported. Recommendations for the management of persistent or recurrent postprostatectomy stress urinary incontinence (SUI) after failed male sling do not exist. The aim of this study was the prospective evaluation of the efficacy of repeat RTS (RRTS) in patients after failed first RTS. Between March 2007 and August 2009, 35 patients with mild to severe SUI after failed first RTS were treated with a second AdVance sling (American Medical Systems, Minnetonka, MN, USA). Preoperative and postoperative evaluation included daily pad use, 1-hr pad test, postvoiding residual (PVR) urine, uroflowmetry, and quality-of-life (QoL) scores. After 6 mo, 45.5% (15 of 33 patients) showed no pad use; 30.3% (10 of 33 patients), one dry "security" pad; 3% (1 of 33 patients), one wet pad; 6.1% (2 of 33 patients), two pads; 3% (1 of 33 patients), pad reduction ≥50%; and 12.1% (4 of 33 patients), treatment failure. After 16.6 mo, 34.5% (10 of 29 patients) showed no pad use; 37.9% (11 of 29 patients), one dry "security" pad; 3.4% (1 of 29 patients), one wet pad; 3.4% (1 of 29 patients), two pads; 10.3% (3 of 29 patients), pad reduction ≥50%; and 10.4% (3 of 29 patients), treatment failure. Daily pad use and pad weight decreased significantly. PVR and uroflowmetry results showed no significant change. QoL improved significantly. Postoperative acute urinary retention was observed in 23.6% of patients. RRTS is an effective and safe treatment option for the management of SUI after failed first RTS.
