Correlation of Renal Dimensions with Body Surface Area Among Indian Newborns in A Tertiary Care Hospital

Abstract

Kidney size is crucial for evaluating renal growth and abnormalities clinically.  An observational study was performed on 150 newborns in a western India hospital to correlate renal dimensions (length and width via USG) with BSA of newborns. Mean renal lengths were 36.57±4.13mm and 36.944.03mm, and widths were 17.70±2.43mm and 18.41±2.84mm on the right and left sides, respectively. A strong association was observed between BSA and renal length (p<0.001) on both sides. Right renal width showed a statistically significant association with BSA, unlike left renal width. A positive yet weak correlation was found between BSA and renal width. In neonatal renal disorders, assessing renal length offers better clinical insights than measuring renal width.
