Anuria secondary to percutaneous needle biopsy of a transplant kidney: a case report.

Unexplained deterioration of renal function after renal transplantation is often an indication for percutaneous needle biopsy of the allograft. This procedure, even when supplemented by modern radiographic techniques, is not without complications. We report a case of anuria secondary to subcapsular hematoma following an ultrasound-guided needle biopsy. Diagnosis, operative management and postoperative care are discussed.
