Page Kidney Following a Nonepisode Protocol Renal Allograft Biopsy: A Case Report.

Page kidney refers to a clinical condition that is characterized by the acute onset of hypertension and renal dysfunction owing to external compression of the kidney by a hematoma, tumor, lymphocele, or urinoma. We report a case in which Page kidney occurred after a nonepisode protocol renal allograft biopsy. A 31-year-old man with end-stage renal disease received a living related kidney transplant from his father. One year later, a nonepisode protocol renal allograft biopsy was performed. A day later, the patient's serum creatinine level increased to 4.23 mg/dL, and a subcapsular renal hematoma was detected using ultrasonography and computed tomography. Page kidney was diagnosed, and immediate surgical removal of the hematoma was performed. Nine days after the operation, the patient's serum creatinine level had improved to 1.89 mg/dL. Page kidney is a serious but treatable complication of renal allograft biopsies, and clinicians should pay attention to such complications, even in the setting of nonepisode protocol renal allograft biopsies.
