Abstract

Between the year 2010 to 2021, 25 patients noticed involuntary leakage of urine from the vagina within 10-40 days after surgical procedures in obstetric (n=2) or gynecological (n=23) departments. The average age on the date of the surgical management of the women was 45.6 years (from 22 to 61). Operations in 15 of the patients were performed via laparatomic access, transvaginal approach was used in 3, and the remaining 7 underwent laparoscopic surgical procedures, and the most frequent operation was hysterectomy done in 20 (80.0%) cases. The patients were referred to the urology center under the department of Belarusian State Medical University for further examination and possible management. Investigation results revealed, that, all women had a combination of ureteral injury (UI) and uretero-vaginal fistula (UVF).Taking into account the clinic’s experience in the treatment of such patients, their management was divided into 2 stages. At the first stage, two patients underwent reconstructive repair surgeries (ureteroneocystoanastomosis) via an open access within 1-2 days after admission into the urology hospital, 14 women had D-J stent insertion, percutaneous nephrostomy (PCN) was placed in 8 cases, and a D-J stent + PCN tube inserted in 1. Analysis during a follow up inpatient study after 3 months, revealed the 2 patients who underwent reconstructive repair surgeries and the 8 after removal of stents had a good treatment outcomes. Fifteen patients underwent operations in the 2nd stage: endoscopic management was carried out in 7 patients (dilation (bougienage) of ureteral stricture + D-J stent placement, endoureteroplasty with endotomic stent placement), and reconstructive repair surgeries (ureteroneocystoanastomosis) via open access in 8 patients. Long-term results were followed up in all patients within the period from 18 months to 4 years. Good management outcomes were achieved in 19 (76.0%) patients, and satisfactory outcomes in 6 (24.0%). Endoscopic treatment of patients of the study group showed high efficiency, its usage in 15 (60.0%) cases, helped in restoring ureteral patency and adequate urodynamics on the side of the injury using minimally invasive technologies. All patients after surgical treatment of UI and UVF need a long-term follow-up.
