AI Article Synopsis

  • The study examines the management and outcomes of ureterovaginal fistulas over a 13-year period, assessing demographic data, diagnostic processes, and treatment effectiveness.
  • Out of 19 cases identified, most fistulas occurred post-hysterectomy, with a primary focus on conservative treatments like ureteral stenting and reimplantation, achieving an 83% success rate in conservative management.
  • The findings suggest that ureteral stenting is effective for select patients, while more complex cases might require ureteral reimplantation as the preferred treatment option.

Article Abstract

Objective: We describe the management and outcomes of ureterovaginal fistulas over a 13-year period and present a treatment algorithm.

Methods: We performed a review of ureterovaginal fistula cases between January 2005 and December 2017 at our tertiary academic center. Demographics, diagnostic approaches, and treatment outcomes were assessed.

Results: Nineteen cases of ureterovaginal fistula were identified. Fistulas developed after hysterectomy in 18 cases and cesarean delivery in 1 case. Our primary treatment was conservative management with ureteral stenting in 12 and reimplantation in 6 cases. There was 1 case of spontaneous resolution. Ureteral stenting was successful in 11 (92%) of 12 patients. Stents were left in place for an average of 66 days (27-92 days). Complications of stents included pyelonephritis in 2 cases (18%) and stricture in 1 case (9%). Ultimately, conservative management was successful in treating ureterovaginal fistulas in 10 (83%) of 12 cases. The indications for primary ureteral reimplantation were concurrent vesicovaginal fistula in 3 cases, history of ureteral injury with surgical repair during the index surgery in 2 cases, and a 1-year delay in diagnosis in 1 case. A variety of follow-up surveillance methods were used, including tampon tests, computed tomographic urograms, retrograde pyelograms, and MAG-3 Lasix renal scans.

Conclusions: In carefully selected patients, ureteral stenting results in high cure rates for posthysterectomy ureterovaginal fistulas and should be considered first-line therapy. Complicated ureterovaginal fistulas may be best managed by primary ureteral reimplantation.

Objective: This study aims to perform a systematic review and meta-analysis to compare the incidence of specific postoperative urologic complications, such as vesicovaginal fistula and ureterovaginal fistula, in patients undergoing minimally invasive radical hysterectomy (MIRH) versus abdominal radical hysterectomy (ARH) for early-stage cervical cancer.

Data Sources: A comprehensive literature search was conducted in PubMed, the Cochrane Library, Web of Science, ScienceDirect, and Google Scholar up to April 2024.

Method: Comparative studies evaluating postoperative urologic complications following MIRH and ARH were included.

Article Synopsis
  • A 43-year-old woman developed both UVF and VVF after a total hysterectomy and initially tried conservative treatment, which didn't work.
  • She then underwent a successful surgical procedure to correct the issues and has remained symptom-free for a year, highlighting the importance of recognizing and managing these rare fistula formations effectively.

Background Laparoscopic hysterectomy is a substitute for the abdominal hysterectomy technique for endometrial carcinoma. Goel's technique is a unique laparoscopic hysterectomy. The main feature of Goel's technique is that vaginal manipulators or myoma screws are not used in the procedure as vaginal manipulators or myoma screws contribute to an increased risk of spread of malignancy in the systemic circulation.
