Page Kidney: A Case of Acute or Chronic Renal Failure & Refractory HTN Presenting after Renal Biopsy

Page Kidney is a relatively rare cause of Acute Renal Failure (ARF) presenting as accelerated and uncontrolled hypertension secondary direct compression of the renal parenchyma by an extrinsic source. This case report describes a 44-year-old male with advanced acute renal failure requiring hemodialysis, hypertension, and initial suspicion for thrombotic thrombocytopenic purpura who developed a case of Page Kidney following retroperitoneal hematoma following a renal biopsy. The patient was medically managed with intravenous nifedipine until blood pressure stabilized after improvement of the hematoma. Usually hematomas are self-resolving, however rarely they can result in the Page phenomenon—extrinsic compression of the affected kidney by the hematoma resulting in a picture that is similar to acute renal failure (ARF). This case highlights the importance of early medical management of blood pressure control after renal compression has been identified.
