title: Magnetic resonance imaging of fetal urinoma.
abstract: Extrarenal collections of urine have long been associated with obstructive uropathy and may preserve renal function by acting as a "popoff" valve. Although urinary extravasation manifested as urinary ascites carries a favorable prognosis, perinephric urinomas occurring prenatally are associated with poor renal function in most cases. We report the case of a baby girl with a urinoma diagnosed by fetal magnetic resonance imaging and discuss the significance of this radiologic finding.
