Urinary tract injury is a known complication of gynecologic surgery. Intraoperative identification of injury permits prompt repair and potentially lessens postoperative sequelae including patient morbidity and cost. Delayed diagnosis of urinary tract injuries can result in complications beyond the site of the injury, such as genitourinary fistula formation, renal injury, sepsis, and death. The overall rate of urinary tract injury associated with pelvic surgery in women ranges from 0.3 to nearly 1 percent . Bladder injury is approximately three times more common than ureteral injury. Up to 2.4 percent of patients may require concomitant urologic intervention after hysterectomy-related injury to the urinary tract. Mechanisms of injury — There are many ways the lower urinary tract can be compromised during or after surgery Thermal damage from electrosurgery or other energy sources, such as laser or harmonic scalpel, is becoming a more frequent cause of injury to the urinary tract . Additional potential mechanisms of intraoperative ureteral injury include: Crushed with a clamp; Kinked or ligated with a suture or staple; Lacerated or transected during sharp or blunt dissection or while using an energy source; Devascularization or denervation. Ureteral injury is overall rare. Compared with injury to other genitourinary (GU) organs, ureteral injury tends to be more often iatrogenic, occurring during pelvic surgery (gynecologic, urologic, or colorectal surgery). When they occur, the majority of traumatic ureteral injuries are due to a penetrating mechanism, predominantly in young males. Traumatic injuries are frequently associated with other severe injuries. The results of surgical treatment of ureteral injuries (gynecological ureter) were analyzed taken from 10 patients in the Urological Department of Republican Clinical Hospital during 5 years. All the ureteral lesions appeared after interventions related to gynecological disorders. Were researched the methods of diagnosis according to the duration of the pathology, the function of the affected kidney, the indicated methods of treatment, types of plasty. It was established the importance of percutaneous nephrostomy with ultrasound guidance as an unavoidable method which allows restoring the function of the blocked kidney. Clinically and functionally were determined the most adequate periods to effectuate ureteral neoanastomoses and reestablish the function of urinary tract.
