Iatrogenic vesicocolic fistula after gynecologic surgery: a case report.

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
Introduction and importance: We present a unique case of a vesicocolic fistula (VCF) that occurred postoperatively after ovarian cyst surgery, caused by the migration of an intraoperatively forgotten gauze into the urinary bladder. This represents a very rare etiology of VCFs. Case presentation: A patient who had undergone surgery for a giant left ovarian cyst 5 months prior presented with recurrent urinary tract infections and an ultrasound image suggestive of a bladder stone. Cystoscopy, contrast-enhanced computed tomography, and colonoscopy confirmed a VCF with an intravesical foreign body. Surgical management consisted of fistula excision, removal of the gauze, bladder repair, and definitive colostomy. Postoperative evolution was favorable, and the patient remained infection-free at 1 year. Clinical discussion: VCFs are most frequently associated with diverticular disease, whereas iatrogenic causes - particularly due to retained surgical gauze - are extremely rare. This case highlights the diagnostic difficulty when symptoms mimic more common conditions such as recurrent urinary tract infections or bladder stones. Early suspicion of a fistula is crucial in patients with persistent urinary symptoms after pelvic surgery. Management depends on patient factors, comorbidities, and fistula etiology; in this case, advanced age warranted a conservative two-stage approach with a permanent colostomy. Conclusion: In patients with recurrent urinary infections after pelvic surgery and imaging suggestive of bladder stones, clinicians should consider VCF due to migrated foreign bodies in the differential diagnosis.
