The relationship of peritubular capillary density with glomerular volume and kidney function in living kidney donors.

Background: Peritubular capillary rarefaction plays an important role in the progression of chronic kidney disease. Little is known about the relation between peritubular capillary density, glomerular volume and filtration rate in the healthy kidney.

Methods: In this single-center study, we included 69 living kidney donors who donated between 2005 and 2008 and had representative renal biopsies available.
