Renal papillary necrosis in a hemodialysis patient.

We present the first case report of bilateral renal papillary necrosis developing in a patient on hemodialysis. A 37-year-old hypertensive male with chronic glomerulonephritis had a normal retrograde pyelogram one year prior to initiation of hemodialysis. After two years of maintenance dialysis, he presented with gross hematuria and was found to have extensive bilateral renal papillary necrosis. His only predisposing factor was hepatic cirrhosis. It is postulated that recurrent hypotensive episodes associated with hemodialysis may lead to renal papillary necrosis in predisposed individuals. This diagnosis should be considered in hemodialysis patients who develop hematuria.
