Efficacy of Transurethral Vesical Deafferentation with Mid-Urethral Sling Operation for Female Mixed Urinary Incontinence: Preliminary Results.

ABSTRACT

OBJECTIVES: In female patients with mixed urinary incontinence (MUI), a mid-urethral sling operation (MUS) is an effective treatment for stress urinary incontinence (SUI), but urgency urinary incontinence (UUI) frequently persists. We developed a novel transurethral vesical deafferentation procedure and assessed its efficacy in these patients. METHODS: From December 2009 to December 2012, 41 female patients with MUI were enrolled prospectively. After baseline evaluation including urodynamic study and symptom questionnaires (Overactive Bladder Symptom Score (OABSS) and International Consultation on Incontinence Questionnaire - Overactive Bladder [ICIQ-OAB]), patients in the study group underwent both the deafferentation procedure and MUS, and those in the control group underwent MUS alone. The outcome was assessed 3 months after the operation by subjective assessment of SUI and OABSS. RESULTS: At 3 months, the treatment response rate of UUI was significantly higher in the study group than in the control group; UUI was improved in 80 and 57.1% of patients, respectively. SUI was cured in most patients. There were no serious complications, such as voiding symptom and urinary retention. CONCLUSIONS: The transurethral vesical deafferentation procedure combined with MUS is effective for the treatment of MUI. The procedure is simple, safe and efficacious in treating urgency and UUI without affecting voiding function.
