Page Kidney From a Subcapsular Urinoma Following Contralateral Radical Nephrectomy.

Page kidney is a rare cause of hypertension and kidney injury; it results from extrinsic compression of the kidney due to fluid accumulation in the subcapsular space. Hypertensive crisis may be the only presenting clinical sign in patients with Page kidney. Urinomas are a very rare cause of Page kidney with very few cases reported in the literature. Urinoma should be suspected in patients presenting in hypertensive crisis who have a history of recent abdominal trauma, genitourinary malignancy, and renal instrumentation. Patients diagnosed with Page kidney from a urinoma should be managed with the least invasive means possible.
