[Tumor of the urinary tract discovered after renal trauma. Medico-legal implications of a case].

A case of a tumor of the urinary tract discovered after renal trauma is reported. The clinical and radiolocal observations are presented as well as the interest of this case in forensic medicine. A review of the legal aspects recalls the principles of imputability in cases of cancer and trauma. While malignant tumors discovered after renal trauma are often renal cancers, urinary tract tumors can also be revealed after renal trauma. This unfrequent circumstance of discovery underlines the importance of control urography in cases of renal trauma, of history taking (smoking), and of the requirement for follow-up investigations if intra-luminal urographic abnormalities persist without damage to the renal parenchyma on the CAT scan.
