## Contribution

This case report highlights the management and successful treatment of a rare isolated traumatic ureteral injury.

## Key findings

- Computed tomography identified hydronephrosis and perinephric extravasation in the patient.
- Insertion of a JJ stent resolved acute renal failure and inflammatory syndrome.
- Three months post-surgery, imaging confirmed no urine leakage outside the urinary system.

## Abstract

Isolated traumatic ureteral injuries are uncommon physiological conditions that can be difficult to manage. This case concerns a 65-year-old man who was referred to the Urology Clinic, suffering left lumbar pain after falling from the same level. A computed tomographic scan revealed the presence of hydronephrosis and a significant perinephric extravasation. The patient underwent the insertion of a JJ stent due to acute renal failure, inflammatory syndrome, hydronephrosis, and the existence of a large urinoma. Postoperatively, remission of the inflammatory syndrome and acute renal failure was observed, and from a clinical point of view, the patient became asymptomatic. Three months after the surgery, the imaging studies show no urine leakage outside the urinary system.
