Twenty-year outcome of cutaneous vesicostomy.
Forty cutaneous vesicostomy urinary diversions were done at our hospital from 1958 to 1961. Of these cases 30 patients have been followed every 6 months or until death. The vesicostomy-related failure rate was 8.6 per cent, with new stones forming in 3 additional kidneys. Cutaneous vesicostomy provides long-term preservation of renal function in patients requiring urinary diversion. However, close followup is mandatory to ensure a good result.
