Treatment of Concomitant OAB and BPH

The etiology of men's lower urinary tract storage and voiding symptoms involves a contribution from both detrusor and outlet. As such, treatment of benign prostatic enlargement (BPE) ± benign prostatic obstruction (BPO) with standard alpha-adrenergic blockade and 5-alpha reductase inhibitor therapy may leave a population of men with persistent and bothersome urinary storage symptoms. An abundance of adequately powered, randomized, placebo-controlled trials indicate that the use of antimuscarinics and beta-3 adrenergic agonists, either alone or in combination with standard BPE/BPO therapy, leads to improvement in storage symptoms. At the same time, metrics associated with urinary emptying, such as maximum flow rate, post-void residual urinary volume, and incidence of treatment-associated urinary retention, appear to be stable and not significantly impacted by the addition of antimuscarinics.
