Use of computerized tomography to diagnose complications of percutaneous renal biopsy

Academic Article

Abstract

  • Retrospectively, 342 percutaneous renal biopsy cases were analyzed for hematocrit changes and recorded complications. Prospectively, 20 consecutive patients undergoing percutaneous renal biopsy, from May through October, 1977, with fluoroscopic techniques underwent a CT scan of the abdomen one day following percutaneous renal biopsy. Fourteen of these patients had a repeat scan one to three months after biopsy. The data reveal an 85% incidence of perirenal hematoma formation in 20 consecutive patients following percutaneous renal biopsy as determined by CT scanning. Fourteen of these documented perirenal hamatomas occurred with little or no change in hematocrit, blood pressure, or pulse rate. Only one patient had a clinically evident complication, evidenced by flank pain and a 10% decrease in hematocrit. All observed hematomas, as demonstrated by follow-up CT scan, resolved at one to three months without residual calcification. It is noteworthy that the renal capsule did not limit accumulation of a hematoma within the subcapsular space, thus explaining why compression of the renal parenchyma leading to hypertension occurs rarely.
