Rectovesical Fistula Caused by a Self-Inserted Intravesical Foreign Body Immobilized by a Giant Vesical Calculus: 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: Intravesical foreign bodies may remain silent until secondary complications occur. Rectovesical fistula caused by an intravesical foreign body is rare. Case Presentation: A 69-year-old man presented with urinary frequency and abdominal distension. Computed tomography revealed a 70.8-mm vesical calculus encasing an approximately 8-cm plastic object, with bilateral hydroureteronephrosis and suspected rectal involvement. Cystoscopic evaluation was limited by the massive calculus. Intravesical indigo carmine appeared from the rectum, and colonoscopy confirmed a foreign body protruding through the anterior rectal wall. Open cystotomy with removal of the foreign body and fragmented adherent stone, suprapubic cystostomy, and diverting transverse colostomy were performed. Delayed laparoscopic fistula closure and subsequent stoma closure were completed. Hydroureteronephrosis and renal function improved, with no recurrence. Conclusion: A long-retained intravesical foreign body can cause rectovesical fistula through stone-mediated fixation. Staged management may be appropriate when inflammation and contamination preclude immediate closure.
