Cystectomy is the chosen treatment of bladder cancer in 400 cases every year in DK. In replacement of the removed bladder, a urinary diversion is constructed using 15cm of terminal ilium (Ad Modum Bricker).

Ureteral strictures are diagnosed in 15% of the cystectomized patients, and these patients are at increased risk of infections, loss of renal function and repeated interventions. The left ureter is diagnosed with 70% of all strictures, presumably due to the construction of the urinary diversion.

A modified urinary diversion have been tested in two small studies. The modified diversion is prolonged with 5cm compared to the conventional urinary diversion. The prolongation permits the urinary diversion to reach both the left and the right side of the abdomen, resulting in greater resection of non-viably distal ureter and less mobilization of the left ureter, lowering the rates of strictures.
