Features of treatment of ureteral injuries

Abstract

Choosing the optimal techniques for the treatment of ureteral injuries is necessary. Damage to the ureter accounts for 3% of cases of injuries of the genitourinary system. More than 70% of iatrogenic ureteric injuries are not detected during surgery. Approximately 75%80% of ureterotraumas are due to iatrogenic causes, of which 65%82% are due to gynecological surgeries. Mechanical injuries of the ureter are much less common than iatrogenic ones. Gunshot and stab wounds of the ureter prevail among mechanical injuries. Thirty-one patients who were treated at the I.I. Janelidze Research Institute of Emergency Medicine with various ureteral injuries from 2003 to 2019 were examined. Patients were divided into three groups according to the time of detection of ureteral injury. Group 1 included patients with ureteral injuries identified during surgery, group 2 included those with ureteral injuries diagnosed within 72 h, and group 3 consisted of patients with ureteral injures detected 72 h later. The choice of treatment techniques for ureterotrauma relied on the general condition of the patient, severity and level of damage to the ureter, timing of its diagnosis, and nature of the complications. On intraoperative detection of ureterotrauma in patients with a stable condition, reconstructive surgery of the ureter should be performed immediately to ensure the passage of urine from the upper urinary tract. If ureterotrauma is diagnosed before 72 h and there are no inflammatory complications, reconstructive ureteral surgery is also appropriate. If an infectious and inflammatory process develops, a staged operation is necessary to drain the upper urinary tract and relieve the developed posttraumatic complications. When ureterotrauma is diagnosed 72 h later, a staged operation is performed to eliminate complications and drainage of the upper urinary tract. Reconstructive surgery is performed not earlier than after 2 months.
