Urodynamic findings in elderly males without prostatic complaints.

Previous evaluations of urodynamic testing in patients with prostatism have been impeded because of a lack of age-matched controls. In this study, 13 asymptomatic male volunteers, ages fifty-two to seventy years, underwent urodynamic testing which included uroflowmetry, water cystometry, and pressure flow study. Comparison of these data to those obtained with patients with prostatism revealed several important differences including maximum flow rate and minimum urethral resistance.
