Abstract
PERCUTANEOUS renal biopsy has become an established diagnostic technic in the evaluation of both adults and children with parenchymal renal disease. Although complications are few,1 the increasing use of renal arteriography has demonstrated an appreciable incidence of arteriovenous fistula after biopsy.2 , 3 Most fistulas are small and disappear spontaneously,3 4 5 but there are several reports of hemorrhage or hypertension requiring operative intervention.6 7 8 9 10 11 Renal exploration has most often resulted in nephrectomy,7 8 9 although there are occasional reports of partial nephrectomy with preservation of the uninvolved portion of the kidney.10 , 11 The case reported below illustrates the extent of hemorrhage that can occur after renal biopsy. . . .
