Control of postbiopsy renal hemorrhage with renal artery vasopressin infusion

Persistent, severe renal hemorrhage resulted from a diagnostic renal biopsy in a 19-year-old woman with chronic renal insufficiency. Infusion of vasopressin into the renal artery through an angiographic catheter produced prompt resolution of bleeding. This method has distinct advantages over surgical intervention or transcatheter embolization in the control of traumatic renal hemorrhage.
