Benign prostatic hyperplasia (BPH) ?,”BPH typically affects men age >50 and is the most common cause of lower urinary tract obstruction in these patients. BPH usually causes lower urinary tract symptoms (eg, increased frequency, urgency, weak stream, nocturia) and a sense of incomplete voiding. Medical treatment for BPH includes alpha-1-blockers (eg, tamsulosin, doxazosin) alone or in combination with 5-alpha reductase inhibitors (eg
finasteride) for symptomatic relief. Surgery may be required for severe symptoms or failing medical therapy.”
