Abstract

Pathological kidney trauma is a special entity. Congenital or acquired lesions may interfere with clinical presentation, radiological imaging, and the therapeutic approach.

Objective: Our objective was to determine the clinical, radiological, and therapeutic features of this entity.

Materials and methods: The medical records of 37 observations were retrospectively collected from January 1992 to February 2022. All cases were explored by a kidney ultrasound and/or a computed tomography scan, and classified according to the American Association of Surgery of Trauma. Pre-existing renal abnormalities were found in 37 patients among 203 (18.2%). The most common underlying lesion were urolithiasis (37.8%) followed by pyelo-ureteral junction syndrome (32.4%). Surgical abstention was decided in 11 cases, four nephrectomies were performed as a matter of urgency, and seven nephrectomies were performed remotely. The cure of uropathy was performed after an average delay of 3 months.

Conclusion: Kidneys with underlying pathology are habitually more susceptible to trauma. Contusions are often benign contrasting with a high nephrectomy rate.
