Surgical Outcomes of Lower Genitourinary Fistula Repair: A Prospective Cohort Study From an Indian Tertiary Hospital.
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionLower genitourinary tract fistulas remain a debilitating condition causing continuous urinary leakage, with vesicovaginal fistula (VVF) being the most common subtype. Despite advances in minimally invasive techniques, the optimal surgical approach remains debated. This study aimed to evaluate and compare the short-term surgical outcomes of laparoscopic, open transabdominal, and transvaginal fistula repairs, while assessing the influence of fistula characteristics, recurrence status, and interposition techniques on success rates. MATERIALS AND
methodsIn this prospective study, 104 women underwent surgical repair: VVF (n=81, 77.8%), ureterovaginal fistula (UVF; n=15, 14.4%), vesicouterine fistula (VUF; n=4, 3.8%), and urethrovaginal fistula (UVVF; n=4, 3.8%). Preoperative evaluation included cystoscopy, vaginoscopy, and selective imaging. Surgical approaches were tailored by fistula site, size, and complexity. Interposition techniques (omental flap, Martius flap, or Surgicel scaffold) and adjunctive procedures (ureteric reimplantation, augmentation cystoplasty, Boari flap, and psoas hitch) were used as indicated. The primary outcome was fistula closure at three months.
resultsAt three-month follow-up, the overall success rate was 97 (93.3%). Among VVFs, closure rates were comparable: laparoscopic (n=18, 90%), open (n=32, 94.1%), and transvaginal (n=25, 92.6%) (p=0.856). All UVF (n=15, 100%), VUF (n=4, 100%), and UVVF (n=4, 100%) cases were successfully treated. Perioperative outcomes favored the transvaginal route for the shortest operative time, while laparoscopy reduced blood loss and hospital stay compared to open repair. Postoperative complications (Clavien-Dindo ≥II) occurred only in the VVF group (n=10, 12.3%).
conclusionsSurgical repair of lower genitourinary fistulas achieved high short-term success across laparoscopic, open, and transvaginal approaches. Success rates were comparable, while perioperative profiles differed: transvaginal repair minimized operative time, laparoscopy reduced blood loss and hospital stay, and open repair was advantageous for complex cases. Tailoring the surgical approach to fistula characteristics ensures optimal outcomes.
