Page kidney after pediatric kidney transplantation: a case report.

INTRODUCTION Page kidney (PK) is a rare condition caused by parenchymal compression due to a subcapsular hematoma. Irreversible damage of the graft may occur if this condition is not recognized and treated properly. CLINICAL CASE We describe the case of a 16-year-old man with chronic renal failure secondary to corticosteroid-resistant nephrotic syndrome (CRNS) caused by NPHS2 mutations. The patient underwent a 5th fifth living-related KT. The graft was placed intraperitoneally and reperfused well without complications. On the 4th postoperative day his labs demonstrated raising creatinine associated with refractory hypertension, gross hematuria and anemia. Urgent ultrasound revealed a subcapsular hematoma with signs of parenchymal compression. PK phenomenon was suspected and urgent surgical intervention decided. COMMENTS PK is a rare but an emergence potentially treatable and reversible complication after pediatric KT. Early diagnosis based on clinical suspicion and suggestive imaging are the key points for a favorable outcome.
