Cutaneous ureterostomy with an introverted pediculate skin flap

Cutaneous ureterostomy with application of an introverted skin flap was performed in 9 cases over a 2-year period. The method had been developed by the authors in view of the prevalence of strictures involving the terminal ureter and the stoma after unintubated cutaneous ureterostomy in case of a normal ureteral lumen. Ureteral drainage had to be resorted to in 2 cases (necrosis of the flap in one, and allergic skin reaction in the other). The intervention was carried out with success not only when the ureteral lumen was normal, but also when it was wide, short, or relatively short.
