OBJECTIVES: To present the urodynamic changes and early results associated with the AdVance male sling. The AdVance male sling is a treatment option for postprostatectomy incontinence (PPI), with the goal of eliminating urinary incontinence without affecting voiding parameters. A concern of any procedure in treating men with PPI is whether the treatment induces obstruction and causes retention. METHODS: Data were prospectively collected from 13 patients undergoing AdVance male sling placement for PPI. Urodynamic testing was performed at baseline and repeated at 6 months postoperatively. A 24-hour pad test and the Incontinence Quality of Life questionnaire were completed preoperatively and at 3 and 6 months postoperatively. RESULTS: The median age at the procedure was 63.3 years (range 44.7-74.7). The mean preoperative and 6-month postoperative patient-reported pad use was 4.52 and 1.04, respectively (2-tailed t test, P = .0009). The 24-hour pad test, performed preoperatively and at 6 months postoperatively, yielded a pad weight of 779.3 and 67.6 g, respectively (P = .03). The Valsalva leak point pressure improved significantly (P = .032), but the detrusor voiding pressure, postvoid residual urine volume, and maximal and average flow rates remained relatively unchanged. At 3 and 6 months postoperatively, the Incontinence Quality of Life scores had improved significantly compared with the preoperative scores (P <.01). CONCLUSIONS: These results are encouraging, because this series has demonstrated a significant improvement in patient-reported pad use, 24-hour pad test weights, and Valsalva leak point pressure without signs of obstruction. The improvement in incontinence was accompanied without any changes in the other voiding parameters and with significant improvement in the quality-of-life measures. Ongoing studies with longer follow-up are pending to compare their results with these promising early results.
