Abstract
Measurement of the thickness of glomerular basement membranes is required for the diagnosis of thin membrane nephropathy. Over the years various morphometric methods have been used but some are laborious so there is a need for establishing a simplified method for measuring thickness. In the present study 20 renal biopsies were used to carry out a comparative morphometric analysis between 2 methods. The first method was based on measuring thickness at the maximum number of available points, whereas for the second method, thickness was measured at only 5 points per loop. Since both methods gave mean values that are not statistically different in each patient, the authors recommend that the simplified method be used routinely for diagnosis.
