Combination Treatment With an α-Blocker Plus an Anticholinergic for Bladder Outlet Obstruction: A Prospective, Randomized, Controlled Study

Abstract

Combination treatment with an alpha-blocker (tamsulosin) plus an anticholinergic (tolterodine) improves quality of life in patients with bladder outlet obstruction and concomitant detrusor instability. Interestingly, no acute urinary retention was observed and tolterodine did not affect the quality of urine flow or residual urine volume. The proposed combination appears to be an effective and relatively safe treatment option in patients with bladder outlet obstruction and detrusor instability.
