Our experience with the urinary diversion especially the end cutaneous ureterostomy with or without contralateral nephrectomy as the last resort option to control the otherwise intractable life threatening bladder post-irrediation hemorrhage is the subject of this study. Among our patients who have undergone various forms of conservative treatment for severe hemorrhagic cystitis following radiotherapy, 17 had to be treated surgically. Of the 17 who underwent urinary diversion 15 responded favourably and 12 were completely free of bleeding. 3 experienced temporary symptomatic relief. It was the underlying disease however, that determined finally the fate of these patients.
