Modified pelvic anterior exenteration.

During a 20-year time period, 117 patients with various histologic types of cancer underwent pelvic exentereation. Six of the 107 patients who needed anterior exenteration with urinary diversion received partial excision of the urinary bladder and modification surgery, of which three had uretero-cystostomy, two had mobilization of bladder and uretero-cystostomy and one had uretero-uterostomy. These six patients, except for two, died of disease in 1 year. Two patients are alive and happy, with quality of life because they can urinate normally. We suggest that anterior exenteration should be modified whenever possible to preserve the bladder and not to do an urinary diversion.
