Recurrent Page kidney in a child with a congenital solitary kidney requiring capsular artery embolization.

We report an unusual case of a child with a congenital solitary functional kidney complicated by a sports-related posttraumatic Page kidney. The child developed severe hypertension and renal insufficiency requiring percutaneous intervention to preserve renal function. The literature is sparse with no definitive guidelines for the treatment of Page kidney. Following the initial unsuccessful treatment with percutaneous drainage and sclerotherapy procedures, the child ultimately required catheter-directed particle embolization of the capsular arteries to resolve a recurrent subscapsular hematoma definitively. This was successful in preserving renal function and stabilization of the clinical manifestations of the Page kidney.
