Abstract

Background: Multiple renal pathogenesis manifested as unilateral or bilateral size changes, therefore there should be normative reference data for proper comparison. Our goal is to determine normal standard value ranges for renal dimensions in pediatric population in Karachi. Sonographically renal length in 150 children were measured and correlate with age, gender, body height, weight and BMI. Objective: Sonographic Measurement of Normal Renal Size and Correlation with Somatic Variables in Subset of Karachi Pediatric Population. Methods: A six month cross sectional hospital based assessment of kidney size (length, width) was evaluated with the help of sonography. XarioTM 200 Toshiba with convex 3.5 frequency transducer will be used. The mean renal dimensions with standard deviation (SD) were estimated for every group of age. The renal length and width were determined and corresponded with different somatic variables. Descriptive statistics with Regression analysis was done. Results: The normal length and the width of kidneys and its ranges were obtained. Right kidney length moderately and significantly correlated with height and weight (r=0.651, r=0.654) and age (r=0.538) respectively. However, moderately insignificant with BMI (0.129). Lefts kidney moderately and significantly correlated with height and weight (r=0.665 r=0.705), negative insignificant with age (0.564) and moderately weak insignificant relationship with BMI (0.174). Conclusion: The research presents the normal range parameters of renal size and measurements by sonography in healthy pediatric population in Karachi. Guideline measurements of kidneys represent a statistically important and comprehensive interaction with specifications of growth which allows us to easily calculate the renal size by derived regression analysis.
