Abstract:
Uroflowmetry is important and simple method in the evaluation of prostatism and lower urinary tract obstruction. But nomogram of old males was not made till now in Korea. And the aim of our study was to provide a control group of males without prostatism who were in relevant age group. So, we investigated 312 males, who were over 50 years and had no subjective voiding problem. And we select 173 males, whose symptom scores were less than 6 out of 27 possible points of Madsen & Iverson's score system and nomogram was made. The 173 males were divided in 5-year groups and we gained maximal flow rate(MFR) and average flow rate(AFR). It was found that the mean value of MFR and AFR decreased from 20.5 t 8.lm1/sec and 13.2+/-5.8ml/sec at the A group( 50-54 years) to 15.4+/-6.1ml/sec and 9.3+/-4.5ml/sec at the G group(over 80 years). The mean voided volume was 211mL. The MFR and AFR are very closely related to the voided volume(P<0.01) and the adjusted maximal flow rate has been tested clinically by comparing preoperative voidings and postoperative voidings of prostatectomy patients. We conclude that this nomogram is very useful in diagnosing and follow-up of patients with BPH or lower urinary tract obstruction.
