Computed tomography revealed a 70.8\u2010mm vesical calculus encasing an approximately 8\u2010cm 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.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>A long\u2010retained intravesical foreign body can cause rectovesical fistula through stone\u2010mediated fixation.
