Average Kidney Size in Local Pediatric Population by Ultrasonography

Abstract

Objective: To determine the average renal size in local pediatric population by ultrasonography.
Study Design: Cross- sectional, descriptive study
Place and Duration of Study: This study was conducted at the Department of Radiology, Kuwait Teaching Hospital, Peshawar, over a 6 months period from 1st July 2024 to 31 December 2024.
Methods: Total 217 patients were included. The sample size was calculated using WHO calculator, for mean and SD of renal length =6.7cm+/-0.6, absolute precision is 8%, relative precision is 0.011% and confidence level is 95%. Results: Mean and SD for age was recorded as 7.76+1.93 years. Mean and SD for kidney length was recorded as 8.64+0.96 cm and for renal width, Mean and SD was recorded as 3.4+0.12 cm. The frequency of male pediatric
patients were recorded as 111 (51.15%), and female patients were 106 (48.84%).
Conclusions: Age did not significantly affect renal width or length. When looking at potential renal disease, normal ranges of renal parameters are crucial for comparison.
