Abstract. Objectives: To determine the effect of patient's age, race, Boyarsky score, and urinary flow rate on type of treatment selected for benign prostatic hyperplasia (BPH) and to evaluate maintenance of treatment at 1 -year follow-up. Methods: Subjects in this prospective study, conducted in a referral center prostate clinic, were 174 consecutive patients, aged 67.6 ± 10.8 years (mean ± SD), with previously untreated BPH. Patients underwent structured interviews and uroflowmetry, then completed the Boyarsky Symptom Index. Blinded to these data, one physician described four treatment categories in a nonjudgmental fashion, always using the same order: watchful waiting; finasteride and alpha-blocker; thermal therapy, balloon dilation, and a prostate stent; and transurethral prostate resection. Treatment choice was entirely that of the patient. Independent variables were patient's age, race, symptom score, and uroflow; the dependent variable was treatment choice. At 1 year, the same physician interviewed patients to evaluate maintenance of therapy. Results: Only symptom score and flow rate were predictive of treatment choice, high scores and low flow being associated with more aggressive treatment choices (P = 0.001). Most patients, regardless of symptom severity, chose interventions less aggressive than surgery and more aggressive than watchful waiting. At 1 year, 85% of patients continued to be maintained on their original treatment. Conclusions: Men with mild or moderate BPH prefer interventions of moderate aggressiveness; race and age make little or no difference. If maintenance of treatment indicates patient satisfaction, most patients appear to remain satisfied with therapy they select.
