Abstract

The flow rate nomogram was based on 204 flow rate measurements in l65 Korean normal men who ranged in age from 20 to 45 years. Using this nomogram, we tested 10 patients with clinically evident outflow obstruction by flowmetry. In 9 of the maximal flow measurements, the nomogram values were less than minus Z standard deviations. The maximal flow rate value after prostatectomy increased an average 2.41 standard deviations. (p=0.006) The use of flow rate nomogram appears to differentiate reliably normal from obstructed individuals and also is highly useful in the postoperative follow up of urinary outflow obstruction.
