Page kidney: A cause of acute renal allograft dysfunction

Page kidney is a rare but reversible cause of secondary hypertension due to renin–angiotensin–aldosterone system activation from external renal parenchymal compression. We report acase of a 30-year-old male renal transplant recipient who developed oliguria and refractory hypertension in the early postoperative period. Imaging revealed a spontaneous subcapsular hematoma causing graft compression. Surgical capsulotomy with hematoma evacuation was performed. The patient had an uneventful recovery, with stable graft function at 1-year follow-up. This case highlights the importance of early recognition and timely surgical intervention to prevent irreversible graft dysfunction in posttransplant Page kidney.
