Abstract
Objectives: To determine the renal size in normal Indian
children by sonography.
Settings: Pediatric teaching hospital, Mumbai, India.
Duration: 1.5 years.
Design: Cross-sectional observational study.
Participants: 1000 normal Indian children aged 1 month - 12
years.
Methods: Sonographic assessment of renal size (length, width
and thickness) was performed using Philips real time
mechanical sector scanner of 3.5-5 MHz frequency with
electronic caliper. The mean renal dimensions and volume were
calculated for each age group with ± 2SD. The renal length and
calculated renal volume were correlated with somatic
parameters like age, weight, height and body surface area.
Regression equations were derived for each pair of dependent
and independent variables.
Results: No statistical difference was found in renal size
between sexes and between right and left kidney. A strong
correlation was seen between renal size with various somatic
parameters, the best correlation was between renal size length
and body height (coefficient of correlation=0.9).
Conclusion: This study provides values of renal length (mean ±
2SD) in normal Indian children. Renal length can be easily
calculated by derived linear regression equation.
