ABSTRACT
Background and objectives: Studies have shown that kidney size varies in different populations across the globe. And knowledge of kidney size is important for correct interpretation of imaging studies like ultrasonography in clinical practice. This study was done to assess kidney dimensions in the Terai region, Nepal.
Materials and Methods: This cross-sectional study involved healthy individuals of age 18 to 70 years. Ultrasound of abdomen was done to measure kidney dimensions which included length, width and thickness. Paired t-test was used for assessment of differences between right and left kidney dimensions. Unpaired t-test was used for assessment of differences in renal dimensions between male and female individuals.
Results: There were 98 (47.1 %) males and 110 (52.9 %) females. The mean age was 34.14 years. The mean kidney length, width and thickness were 9.8 (SD 0.9) cm, 5.25 (SD 0.9) cm, and 4.23 (SD 0.7) cm respectively. The length of right and left kidney was 9.65 (SD 0.87) cm and 9.98 (SD 0.89) cm respectively (p = 0.001). The width of right and left kidney was 5.18 (SD 0.79) cm, and 5.32 (SD 0.99) cm respectively (p = 0.12). The thickness of right and left kidney was 4.05 (SD 0.63) cm, and 4.4 (SD 0.72) cm respectively (p = 0.001). When compared between male and female, the mean length, width and thickness were greater in male. However, the difference in only thickness was significant (p = 0.001).
Conclusion: The average length, width and thickness of kidney were 9.8 cm, 5.25 cm and 4.23 cm respectively. The length of left kidney was greater than the right. Male kidney tended to be slightly larger than the female although the difference was not significant.
Key words: kidney dimension, kidney size, renal length
