ABSTRACT: Chronic allograft nephropathy (CAN) is the most important cause of late renal allograft loss. The standard diagnosis of CAN is based on pathological examinations according to Banff'97 scheme. The aim of the study was to evaluate the usefulness of tubular and glomerular proteinuria in non-invasive recognition of vascular changes accompanying CAN (AH--arteriolar hyaline thickening, CV--vascular fibrous intimal thickening). beta 2- and alpha 2-microglobulin (beta 2-m and alpha 2-m), albumin (alb), immunoglobulin G (IgG), total protein (tp) and creatinine (cr) concentration were measured in the second time urine specimen in 66 renal allograft recipients. Then the subsequent renal biopsies were done. The aim of statistical analysis (MANOVA, Stepwise Discriminant Analysis, SDA) was to diagnose CV and AH changes based on results of urine analysis listed above and the patient's age, time after transplantation and serum creatinine level (scr). Results obtained with statistical analysis were in 90.91% and 87.69% identical with CV and AH pathological diagnoses, respectively.
