Introduction. Iatrogenic trauma of the ureters accounts for 1-5.7% of all injuries to the organs of the genitourinary system, it is this that presents the greatest difficulty for diagnosis and the greatest danger in terms of the rate and frequency of development of severe, life-threatening complications (phlegmon of the retroperitoneal space, urinary peritonitis, sepsis.

Description of the clinical case. Patient A., 47 years old. On June 17, 2019, laparoscopic uterine extirpation was performed for fibroids. 06/22/2019, iatrogenic injury of the lower third of the left ureter was diagnosed. Percutaneous puncture nephrostomy on the left was performed as the first stage for urine diversion. At the second stage, ureteroscopy on the left was performed, in which a burn zone was determined in the lower third of the left ureter, up to 0.5 cm in length with a defect of 1/3 of the ureteral circumference. Left kidney stenting was performed. After 2 months, the ureteral stent was replaced. At control computed tomography (4 months after surgery), the left ureter was contrasted along the entire length, no urodynamic disturbances were revealed.

Discussion. Open surgical interventions for iatrogenic trauma of the ureter are long and traumatic, require a long rehabilitation period, accompanied by social maladjustment of patients, therefore the use of X-ray endoscopic methods of treatment is an effective and alternative method of treating this pathology.

Conclusion. In this case, timely detection of iatrogenic damage to the ureter made it possible to perform an effective minimally invasive surgical treatment, which saved the patient from possible severe complications.
