INTRODUCTION: While established in pediatric urology, the laparoscopic use of appendiceal substitution of the ureter in adults is rare.
CASE PRESENTATION: An 83-year-old man developed a 2.5-cm right mid-ureteral stricture as a complication after endoscopic treatment for a ureteral stone. Preoperative imaging confirmed an adequate appendix length. A laparoscopic approach was selected due to its minimal invasiveness, which was considered particularly appropriate for an elderly patient. After isolation with a linear cutting stapler, both ends of the appendix were resected, and a guidewire was passed through. To prevent mesoappendix torsion, the cecal side was oriented cranially before ureteral anastomosis. The operative time was 336 min, with 10 mL blood loss. Postoperative ureteral stone formation resolved spontaneously, and renal function was preserved.
CONCLUSION: Laparoscopic appendiceal interposition is a viable and minimally invasive option for right mid-ureteral reconstruction in selected elderly patients.
