Renal tamponade secondary to subcapsular hematoma.

We report the occurrence of renal biopsy induced subcapsular (SC) hematoma in two patients. The first was a recently transplanted elderly man, while the second was a woman with class IV lupus nephritis. Though hematoma size was initially small, early significant renal dysfunction was noted in both patients followed by eventual recovery of renal function in both patients; the first recovered within one day, while the second case within 10 days.
