Abstract
- PURPOSE: To determine the uroflow rates of normal Korean pediatric male, uroflowmetry was peformed.
MATERIALS AND METHODS
A total of the 237 normal children who ranged in age from 2 to 14 years(mean: 7.2+/-2.1years)was available for this study. Uroflow 1 data(peak and average flow) were plotted in volume-related nomograms in 3 different age groups : 2 to 4, 5 to7 and 8 to 14 years old.
RESULTS
The mean peak flow(10.3+/-3.7, 12.2+/-4.9 and 14.3+/-5.2m1/sec) and average flow(6.4+/-2.6, 7.1)3.0 and 8.3+/-3.4m1/sec) were increased significantly with increasing age(p<0.05). In a same voided volume the peak and average flow rates were not increased significantly with increasing age but, in a same age group they were significantly increased according to the volume voided (p<0.05). Peak and average flow rates in the circumcision group(13.7+/-6.7, 8.3+/-4.7m1/sec) was not significantly different from non-circumcision group(10.9+/-5.0, 16.1+/-3.0ml/sec).
CONCLUSIONS
These uroflow rate nomograms will be useful for the assessment of voiding action related to the voided volume and age in Korean pediatric males.
