Subcapsular renal hematoma is not known complication post some urological interventions such as extracorporeal shockwave lithotripsy (ESWL), percutaneous nephrolithotomy (PCNL) and trauma. Few cases of subcapsular hematomas are reported as a complication post ureteroscopy in the literature. Clinical spectrum varies from spontaneous resolution through acute renal failure secondary to Page kidney. Page kidney is the external compression of a kidney usually caused by a subcapsular hematoma associated with high blood pressure and occasional renal failure. It is named after Dr. Irvin Page who first demonstrated in 1939 that applying external compression on the renal parenchyma could cause hypertension. Various management options are mentioned in literature and depend upon the severity and presentation. Percutaneous drainage is an option for the management of subcapsular hematoma in hemodynamically stable patient.
