Background: Ultrasonography is widely used for assessment of renal pathologies. Measurement of renal size is one of the parameters we use to determine whether the kidneys have increased or decreased in size depending on which we suggest some differentials. Objective: This study was conducted to meet the objective of assessing the ultrasound assessment of renal size in children visiting the Radiology Department of TASH from May2019- August 2019. Methods: Institutional based prospective cross sectional study was conducted. A total of 110 study units were selected by using convenience non randomsampling technique. A structured data collection format was used. After completing the data collection, the data wasanalyzed by SPSS version 25software. An ethical clearance was obtained from ethical review committee of AAU-CHS department of radiology. Verbal consent is received from the parents or guardians of the patients. Results:Out of the 110 children included in the study, 65 were male and 45 were female. There was no significant difference between the renal lengths of male and female (p=0.13). The difference in mean renal lengths between right (6.86cm) and left kidney (7.23 cm) was statistically significant (p= 0.08). There is a good correlation between age and kidney length (r = 0.972), weight and kidney length (r=0.955), body surface area and kidney length (r = 0.940) and height and kidney length (r = 0.932). Conclusions: ultrasound measurement of the renal size in children with renal pathologies necessitates knowing the normal renal lengthranges in accordance with height of the patient. Recommendation: - Possible recommendations will be forwarded based on the results obtained.
