INTRODUCTION: Renal size is an important parameter in evaluation of many renal diseases and is essential for diagnostic, prognostic and follow up purposes. Ultrasonography is the easiest way to assess it. Aim of this study was to establish a nomogram of renal sizes for Indian paediatric population. MATERIALS & METHODS: Sonographic assessment of normal renal dimensions of 200 patients of age < 18 years with no evidence of renal disease and analysis of the data was performed and its dependence on age, gender & laterality was seen. RESULTS: Overall, mean length of right kidney was 70.09 ± 14.67 mm whereas the mean length for left kidney was 72.44 ± 14.51mm. CONCLUSION: Our study provides values of normal renal length and width (Mean + SD) according to the age in Indian children using sonography.
