Abstract

With histologic evidence of benign prostatic hyperplasia (BPH) in nearly 50% of men aged 50 years, and prevalence rates increasing with age, BPH is the most common benign neoplasm of elderly men [1]. Bladder outlet obstruction resulting from the hyperplastic prostate is believed to be secondary to two mechanisms: 1) the static component or bulk obstruction caused by the enlarged prostate encroaching on the prostatic urethra, and 2) the dynamic component mediated by smooth muscle tone within the prostatic stroma. Traditionally, surgery has been the mainstay of treatment for symptomatic BPH. However, clinical practice guidelines developed by the Agency for Health Care Policy and Research and endorsed by the American Urological Association were released to serve as a guide for the diagnosis and treatment of patients with BPH [2]. A new edition of these guidelines will be forthcoming in 2003. Treatment is recommended for the majority of patients with moderate to severe symptoms as defined by the American Urological Association symptom score. Medical therapy is among the recommended treatment options. The availability of medical therapy, which is less invasive and therefore more appealing to many patients, has been associated with huge increases in the total number of patients treated compared with the previous era, when surgery was the only option.
