Ureteral involvement due to Crohn's disease occurs in 3% to 6% of cases. Herein, we present a case of a 22-year-old woman with ileocolic Crohn's disease with right hydronephrosis due to compression of the ureter that was resolved with a 3-stage, minimally invasive procedure (preoperative percutaneous nephrostomy, ureteral stent placement, and sequential laparoscopically assisted ileocolectomy). Percutaneous right nephrostomy drainage permitted us to prevent renal damage before surgery, and successive ureteral double-J catheter placement minimized the risk of ureteral damage during the laparoscopic procedure. The safety and feasibility of sequential minimally invasive management of ileocolonic Crohn's disease involving the right ureter was assessed, and a good cosmetic result was achieved.
