Objective: Morphological development of kidneys according to age and sex was evaluated in this study and data obtained were analyzed statistically. Material and Method: This study was conducted in Radiology Department of Meram Faculty of Medicine in Necmettin Erbakan University. It was performed on 100 subjects (32 male and 68 female) age of 4-47. 200 kidneys were examined with ultrasound imaging technique. Length, width, thickness values of kidneys were measured and volume and shape indexes were calculated. Data were evaluated in SPSS program (10.0 for windows) and paried sample T test statistically. Results: Length, width, thickness and RV of right kidney in male was found to be greater than of the female and of left kidney. Length, thickness and RSI values of left kidney in female was found to be greater than of the male and of right kidney. All results have been discussed and compared with the existing results in the literature. Conclusions: Results attained in the study might be an additional knowledge resource about kidney development and in last years it was decided that they may be useful in sciences such as urology which uses partial nephrectomy and renal transplantation as treatment.
