Abstract

Purpose: To evaluate the efficacy of an alpha-1 adrenergic receptor (α1-AR) blocker for the treatment of female voiding dysfunction (FVD) through a pressure-flow study. Methods: This was a randomized, double-blind, placebo-controlled trial. Women aged ≥18 years with voiding symptoms, as defined by an American Urological Association symptom score (AUA-SS) ≥15 and a maximum flow rate (Qmax) <15 mL/ sec with a voided volume of >100 mL and/or a postvoid residual (PVR) volume >150 mL, were randomly allocated to either the alfuzosin or placebo group. After 8 weeks of treatment, changes in the AUA-SS, Bristol female lower urinary tract symptoms (BFLUTS) questionnaire, Qmax/PVR, and voiding diary were compared between groups. Patients' satisfaction with the treatment was compared. Patients were categorized into 3 groups according to the Blaivas-Groutz bladder outlet obstruction (BOO) nomogram: none, mild, and moderate to severe. Subgroup comparisons were also made. Results: Of a total of 187 women, 154 (79 alfuzosin, 75 placebo) were included in the analysis. After 8 weeks of treatment, the AUA-SS decreased by 7.0 in the alfuzosin group and by 8.0 in the placebo group. Changes in AUA-SS subscores, BFLUTS (except the I-sum), the voiding diary, and Qmax/PVR were not significantly different between groups. Approximately 54% of the alfuzosin group and 62% of the placebo group were satisfied with the treatment. No significant difference was observed between groups according to the presence or grade of BOO. Conclusions: Alfuzosin might not be more effective than placebo for treating FVD. The presence or the grade of BOO did not affect the results. A further study with sufficient power is needed to determine the efficacy of α1-AR blockers for the treatment of FVD.
