title: Ureteral fistula after renal transplantation: the significance of delayed images.
abstract: Urinary leakage after renal transplantation is a serious complication that can lead to diagnostic difficulties. A case is reported of urinoma secondary to ureteral fistula characterized in the routine study by a photon-deficient area. Only the image obtained at 6 h allowed a correct diagnosis. The causes for this are discussed and the need to include a delayed study in the follow-up protocol of these patients is emphasized.
