Spontaneous renal hemorrhage in hemodialysis patients.

Abstract

Dialysis patients have a tendency to bleed, and clinicians sometimes encounter cases with a significant amount of spontaneous hemorrhage. We herein report two cases of spontaneous renal hemorrhage in hemodialysis patients. CASE 1: A 70-year-old male who had received hemodialysis for 8 years presented with right abdominal pain. He had a history of renal failure due to diabetes mellitus. CT showed a right perirenal hemorrhage. Angiography revealed a right renal artery hemorrhage, and catheter embolization was performed. CASE 2: A 76-year-old male who had undergone 7 years of continuous ambulatory peritoneal dialysis and 1 year of hemodialysis presented with right abdominal pain. He had a history of renal failure due to IgA nephropathy. CT showed a right perirenal hemorrhage. He received a blood transfusion and was put on absolute bed rest. At 2 days after admission, his anemia was found to have improved.
