Abstract

Despite the deceptively simple description of benign prostatic hyperplasia (BPH), the actual relationship between BPH, lower urinary tract symptoms (LUTS), benign prostatic enlargement, and bladder outlet obstruction is complex and requires a solid understanding of the definitional issues involved. The etiology of BPH and LUTS is still poorly understood, but the hormonal hypothesis has many arguments in its favor. There are many medical and minimally invasive treatment options available for affected patients. In the intermediate and long term, minimally invasive treatment options are superior to medical therapy in terms of symptom and flow rate improvement; tissue ablative surgical treatment options are superior to both minimally invasive and medical therapy.

Comparison of the improvement in International Prostate Symptom Score by various α-blockers. Effect of α1-adrenergic receptor antagonists on total symptom score in placebo-controlled studies. Total number of patients: alfuzosin (ALF), n = 2208; terazosin (TER), n = 3229; doxazosin (DOX), n = 3947; and tamsulosin (TAM), n = 1331. IR, immediate release; SR, sustained release; S, standard; GITS, gastrointestinal. Additional benefit with α-blockers over placebo is approximately 10% to 15%.
