Uroflowmetric analysis and derivation of nomograms for normal paediatric Indian population between 5 to 15 years of age

Summary: | We aimed to established normal uroflowmetric values and subsequently derived nomograms of maximum flow rate (Q
) and average flow rate (Q
) against voided volume (VV) in children aged 5-15 years at our institute.
A total of 440 children underwent uroflowmetric evaluation with no history of urological, renal, psychiatric, or neurological disorder between 5 and 15 years of age. Each subject data regarding Q
, Q
, VV, time to Q
, and flow time, as well as age, sex, height, and weight were recorded. Of the 440 children, around 300 (68.18%) children could produce a normal flow rate at VV of more than 50 mL. Of the remaining 140 (31.82%) children, 50.00% voided less than 50 mL, and remaining 50.00% had abnormal voiding pattern, staccato or interrupted (21.43% each) and plateau or tower shaped (3.57% each). Cases were divided into two age groups (5-9 years and 10-15 years), and uroflowmetric analysis was done between boys and girls in both age groups to derive nomograms of Q
and Q
.
Q
and Q
flow nomograms were plotted for boys and girls. Mean Q
for boys was 16.68 mL/s and for girls 20.69 mL/s. The mean Q
values were 11.04 mL/s and 8.60 mL/s for girls and boys, respectively. The Q
and Q
values were higher in girls. There were significant increases in flow rates with increasing age, body surface area, and VV in both sexes.
Nomograms for Q
and Q
may be a useful tool in evaluation of lower urinary tract disturbances in children. |
