Background & Objectives: Renal size is an important parameter used in the diagnosis and follow up of renal diseases. However, while making decisions, clinicians must be aware of the dependence of renal length on the anthropometric indices. There is no established nomogram for renal sizes in the Indian population. Therefore, a study was under taken to help standardized a criteria to be used in clinical assessment of certain disease processes largely rely on renal dimensions.
Methods: A prospective observational study was carried on 300 individuals (207 males and 93 females) between the age group of 18 to 30 years in the department of Anatomy King George’s Medical University U.P. Lucknow. Renal length, breadth, thickness and cortical thickness of both sides were measured sonographically and their correlation with sex, weight, and height of individual were determined.
Results: The mean length of left kidney vs. right kidney was 102.4+5.4mm vs. 99.9+5.7mm, respectively, p<0.001. the mean length of kidney in males vs. females was 101.1+5.0 vs. 97.3+6.4 for right side, 103.6+4.7 vs. 99.8+5.8 for left, p<0.001. The mean breadth of kidney in males differed between left vs. right (50.3+3.0 vs. 50.7+3.8, p=0.046). The mean thickness of kidney left vs. right was 37.2+3.5 vs. 36.2+4, p<0.001, the difference remained among gender. Whereas, cortical thickness was not differed between left and right side, but had difference among different gender. With increasing body weight and height, significant increase in kidney length of both the sides was observed (p<0.05).
Conclusion: Mean value of renal length, breadth, thickness and cortical thickness in our population were lower as compared to their western counterparts. The heights of the individual were found to be most important factors affecting the dimensions of kidney. Anthropometries did not show consistent relations i.e. on both sides of the kidney.
