The Influence of Preoperative Bladder Outlet Obstruction on Continence and Satisfaction in Patients with Stress Urinary Incontinence after Midurethral Sling / 대한배뇨장애요실금학회지

ABSTRACT

PURPOSE: We studied the influence of preoperative bladder outlet obstruction (BOO) on postoperative continence rates and patient satisfaction after the midurethral sling procedure. METHODS: A total of 159 women who underwent the midurethral sling procedure were evaluated. Using the Blaivas-Groutz nomogram, we assigned the patients were assigned to Group I (n=37, no obstruction), Group II (n=89, mild obstruction), or Group III (n=33, moderate to severe obstruction). Continence rates, patient satisfaction, urinary sensation scale and uroflowmetry were evaluated postoperatively. RESULTS: There were no significant differences in continence rates, satisfaction, or postoperative maximal flow rate between the 3 groups. Postoperative urgency was improved after surgery in Groups I and II (P<0.05) but not in Group III. CONCLUSIONS: BOO does not seem to be a risk factor for failure after the midurethral sling procedure. However, BOO may be considered as a potential factor for persistent storage symptoms after the midurethral sling.
