During a 20-year time period, 117 patients with various histologic typ
es of cancer underwent pelvic exentereation. Six of the 107 patients w
ho needed anterior exenteration with urinary diversion received partia
l excision of the urinary bladder and modification surgery, of which t
hree had uretero-cystostomy, two had mobilization of bladder and urete
ro-cystostomy and one had uretero-uterostomy. These six patients, exce
pt for two, died of disease in 1 year. Two patients are alive and happ
y, with quality of life because they can urinate normally. We suggest
that anterior exenteration should be modified whenever possible to pre
serve the bladder and not to do an urinary diversion.
