Percutaneous renal biopsy: three years of experience with the biopty gun in 761 cases--a survey of results and complications

Abstract

From 1.1.1993 to 12.31.1995 we performed 761 consecutive biopsies on 509 non-selected patients. The most frequent diagnoses in 351 biopsies (39.4%) on native kidneys were 262 cases of glomerulonephritis (74.6%) and 167 of so-called benign nephrosclerosis (47.6%). With 410 biopsies (60.6%) on allograft kidneys 219 cases (78%) showed signs of interstitial rejection, 14 cases (5%) vascular and 49 cases (17%) interstitial as well as vascular rejection. Only after 5 biopsies (0.66%) clinical relevant complications (3 perirenal haematomas, 1 AV fistula, 1 vesical tamponade) appeared. Again percutaneous renal biopsy is proven to be a diagnostically efficient and safe tool at the same time even when used in a large number of non-selected patients, so that an ambulant performance may be discussed. The relatively frequent diagnosis of a so-called benign nephrosclerosis seems to indicate the need for an intensified examination of this disease.
