A sonographic study of kidney dimensions in a sample of healthy Jamaicans.
A sonographic study of 49 randomly selected healthy adult Jamaicans was conducted to establish a guide for renal dimensions in the population. The mean length of the right kidney was 9.7 +/- 0.7 cm and the left 10 +/- 0.7 cm. The left kidney was longer than the right in the overall group and in males. There was no difference in width between right or left kidneys in the group as a whole or within either gender. There was a significant association between the weight of males and width of their kidneys; however, this association was not seen in females. The lone association between weight of participants and renal length occurred in females and only with respect to the left kidney. Lengths and widths of kidneys were not associated with height in either gender. Renal surface area (RSA) was similar between the genders and also between right and left kidneys. Similarly, there was no significant association between renal length and body surface area (BSA) overall or within the genders. Renal index (RI) which is more reliable at assessing renal parenchymal mass than renal length alone was 20.92 and 22.86 for the right and left kidneys, respectively, in males. Similarly, RI for the right and left kidneys in females was 23.76 and 25.54, respectively.
