A 72-year-old patient was treated in our department for an invasive bladder TCC by cystoprostatectomy with the intention to create an orthotopic neobladder. During surgery it appeared to be impossible to mobilize part of the preterminal ileum into the small pelvis to make an anastomosis with the urethral stump. However, incidentally, a Meckel's diverticulum of about 8 cm was found on the preterminal ileum which could easily be mobilized onto the urethral stump. The intestinal insertion of the diverticulum served as the lowest point of the pouch. Above the diverticulum, we created a modified Studer-pouch. No major postoperative complications occurred and during the follow-up period of more than 12 months micturition was good.
