Role of uroflowmetry in the assessment of lower urinary tract obstruction in adult males.

A group of 173 prostatic patients were submitted to a prospective study to determine the respective value of symptoms, uroflowmetry, endoscopic and radiological findings in the assessment of the degree of urinary obstruction. Uroflowmetry proved to bring objective evidence of the degree of obstruction with a reasonable degree of accuracy. Maximum urinary flow appears to be more accurate than other flow parameters in the determination of lower urinary tract obstruction.
