title: Reversible acute anuric kidney injury after surgical evacuation of perinephric hematomas as a complication of renal transplant biopsies.
abstract: Percutaneous renal transplant biopsy is the gold standard investigation to diagnose the cause of renal allograft dysfunction. There are inherent risks to this investigation, despite the procedure becoming safer due to the increased utilization of ultrasound-guided techniques. These biopsy risks can be increased when there is acute rejection present with a swollen transplanted kidney. Subcapsular hematomas are not uncommon after percutaneous renal transplant biopsies, but we describe two cases of post-biopsy subcapsular hematoma which were associated with acute renal allograft dysfunction in pediatric renal transplant recipients who did not have acute rejection.
