AIMS: This prospective, randomized, controlled clinical trial was performed to demonstrate the 12 months safety and efficacy of transurethral radiofrequency energy (RF) collagen micro-remodeling in women with stress urinary incontinence (SUI). MATERIALS AND METHODS: Women with SUI, bladder outlet hypermobility, and leak point pressure (LPP) > or =60 cmH(2)O were randomized to RF micro-remodeling or "sham treatment." Adverse events (AEs) were recorded. Incidence of > or =10 point incontinence quality of life (I-QOL) score improvement, a magnitude of improvement with a demonstrated responsiveness to patient satisfaction with treatment and to > or =25% reduction in both incontinence episode frequency and stress pad weight, served as a subjective outcome measurement. Change in mean LPP served as an objective outcome measurement. RESULTS: 110 women underwent RF micro-remodeling and 63 underwent virtually identical "sham treatment" (with the exception of RF delivery). The 12 months RF micro-remodeling safety profile was statistically no different than that of sham treatment (a brief bladder catheterization). Seventy-four percent of women with moderate to severe baseline SUI experienced > or =10 point I-QOL score improvement at 12 months (P = 0.04). Women who underwent RF micro-remodeling demonstrated LPP elevation at 12 months, while sham treated women demonstrated LPP reduction (P = 0.02). CONCLUSIONS: Non-surgical, transurethral RF micro-remodeling is a safe treatment for women with SUI. In women with moderate to severe SUI, this novel therapy resulted in statistically significant improvement in quality of life of a magnitude associated with patient satisfaction with the treatment. Women who underwent RF micro-remodeling demonstrated a statistically significant elevation in mean LPP at 12 months.
