Hypertrophy of the Normal Human Kidney Following Contralateral Nephrectomy

Abstract

Intravenous pyelograms were performed on 22 kidney donors, both before and from 2 weeks to 4 years after nephrectomy. A significant increase in kidney size was demonstrated by four different measurements. There was no significant difference in the increase in kidney size between the donors over 40 and those under 40 years of age. A significant increase in glomerular filtration rate per kidney was also found, but this increase could not be correlated with the increase in kidney size.
