Laparoscopic continent cutaneous urinary diversion using a modified Yang–Monti technique in an adult: A case report including 5-year follow-up

Abstract Continuous cutaneous urinary diversion is challenging when the appendix is physically unavailable. The Yang–Monti channel is an alternative to the tunneled appendix for urinary diversion. We present a case involving a 49-year-old man who underwent total urethrectomy and cystostomy 10 months previously. No tumor recurrence was observed; however, the patient experienced severe catheter-related bladder irritation after the procedure. The patient was readmitted to the authors’ hospital and underwent laparoscopic continent cutaneous urinary diversion using extracorporeal construction of a modified Yang–Monti channel. The operation lasted 232 minutes, with an estimated blood loss of 10 mL. The patient was discharged from hospital 6 days after surgery and removal of the cystostomy tube. After this, clean intermittent catheterization was performed every 3 hours for 4 weeks. Five years after the procedure, the modified Yang–Monti channel was still used for clean intermittent catheterization without any stomal stenosis being observed. The patient was satisfied with his postoperative quality of life.
