Purpose: To compare the first-time success rate and prognosis of repairing vesicovaginal fistula (VVF) by transvaginal and transvesical approaches, and to highlight a modified transvaginal repair technique which only require single layer closure of an annular vaginal flap.

Methods: Retrospective analysis of 57 consecutive patients who underwent VVF repair between 2007 and 2021. Fistula characteristics, operative factors, post-surgical complications and outcomes were analyzed.

Results: A total of 57 women with a median age of 50.4 (27-75) years were included. The history ranged from 7 days to 8 years, with an average of 20 months. 56 cases (98.2%) of VVFs were caused by pelvic surgery, and only one resulted from difficult labour. 11 cases (19.3%) had a history of surgical repair failure. All 57 cases of surgery were smoothly completed. Among them, 17 patients underwent transvaginal repair, whereas 40 (70.2%) women had transvesical repair. Transvaginal approach had a significantly shorter operative time, less intraoperative blood loss, reduced postoperative hospital stay, less hospitalization cost and lower minor complication rates than transvesical group (p < 0.05). No serious complications occurred in the two groups. No cystostomy was performed in the transvaginal group, but 12 cases (30%) in the transvesical group. The average follow-up time was 18.5 (3-48) months. The first-time success rates of transvaginal and transvesical techniques were 82.3 and 75%, respectively.

Conclusion: VVF repair with single layer closure of an annular vaginal flap is a technically feasible, simple and successful approach with significantly better operative parameters and lower complications rates.

Objective: To compare the diagnostic value of transvaginal ultrasound (TVS) and magnetic resonance imaging (MRI) in cesarean scar pregnancy (CSP) by a method of meta-analysis.

Methods: Studies on TVS and MRI for CSP were collected from PubMed, Cochrane Library, Embase, Web of Science, China National Knowledge Infrastructure (CNKI), Wanfang data, and Chinese Scientific Journal Database (VIP database) until April 1, 2024. Stata 15.

Transvaginal evisceration is a rare, potentially life-threatening condition involving herniation of intra-abdominal contents, typically the small bowel, through a defect in the vaginal wall. Most commonly observed in postmenopausal women with a history of pelvic surgery or trauma, it necessitates prompt surgical intervention. We report a unique case of transvaginal evisceration in a 67-year-old postmenopausal female with rectovaginal prolapse following minor trauma.

Mid-term outcomes of moderate-severe cystocele repairing with autologous fascia lata harvested through a small incision.

BMC Surg

December 2024

Department of Obstetrics & Gynecology, Peking University Third Hospital, No. 49 Huayuan North Road, Haidian District, Beijing, 100191, China.

Introduction And Hypothesis: To investigate the mid-term outcomes of transvaginal repair for moderate-severe cystocele using autologous fascia lata harvested through a single small incision.

Methods: Between February and October 2022, 35 patients with moderate to severe cystocele undergoing transvaginal repair with autologous fascia lata were included. Patient demographics and perioperative data were collected, with follow-ups through outpatient visits or phone calls.

Background/aim: Cesarean section (CS) is a widely performed operation worldwide but data about uterine closure are lacking. We aimed to evaluate scar niches and compare single-layer and double-layer uterine closure at 6 months following CS.

Materials And Methods: This prospective randomized trial assessed 56 women undergoing single- or double-layer uterine closure.

Article Synopsis
  • The study details a modified transvaginal repair technique (V-NOTES) for treating apical vesicovaginal fistulas (VVFs) in 26 patients, with 17 undergoing the V-NOTES procedure between January 2020 and January 2023.
  • Outcomes showed an 88.2% success rate, with an average operative time of 104.2 minutes and minimal blood loss (10.45 ml).
  • No major complications arose, and even initially failed repairs were successful on subsequent attempts, indicating that V-NOTES is an effective and safe treatment option for apical VVFs.
