Systematic review of therapy for men with overactive bladder.

Lower urinary tract symptoms (LUTS) can have multiple causes in men. Overactive bladder (OAB) is an empirical diagnosis used as the basis for initial management after assessing symptoms, physical findings, urinalysis and other indicated evaluations. In men, the diagnosis is complicated by the potential of benign prostatic hyperplasia (BPH), which is a histological diagnosis. Although storage symptoms (i.e., those associated with OAB) are the most bothersome group of LUTS in men with BPH, these patients are usually treated with BPH rather than OAB drugs. The standard pharmacologic treatment of patients with bothersome voiding and storage LUTS at low risk of progression should be an α1-AR antagonist. The combination α1-AR antagonist + antimuscarinic agent is an appropriate and valid option for male patients with voiding symptoms and persistent storage symptoms.
