Lésions urétérales iatrogènes

Ureteral lesions are a rare but very serious complication of various abdominal, pelvic, and even spinal procedures. In clinical terms, they are rarely suspected since the symptoms are non specific and may appear weeks and even months after the injury constitution. Therefore, the diagnosis of an ureteral lesion is often delayed, resulting in an increased morbidity. An ureteral injury may be first diagnosed on CT in a patient evaluated after surgery. In case of high clinical suspicion, CT scanning should include a delayed scan in order to establish the diagnosis of ureteral injury resulting in a urinoma. This may obviate the need for additional invasive imaging studies or unnecessary exploration.
