Complications of Radical Cystectomy and Urinary Diversion: A Retrospective Review of 675 Cases in 2 Decades

A retrospective review was performed on all 675 patients who underwent radical cystectomy and urinary diversion during 2 decades. Of the patients 197 were treated from 1969 to 1979 (group 1) and 478 were treated from 1980 until 1990 (group 2). The mean age of patients in group 1 was 56.7 years versus 64.2 years in group 2 (p < 0.001). The overall operative mortality rate in both groups was 2.5%. A total of 215 patients (31.9%) experienced postoperative complications (within 30 days of surgery). The morbidity rate was nearly identical between the 2 groups (32.0% for group 1 versus 31.8% for group 2, p = 0.962). Of note, however, there was a decreased incidence of wound infections and wound dehiscence among the patients in group 2 compared to group 1. Long-term complications occurred in 198 of the 675 patients (29.3%). At followup group 1 had a 35.5% incidence of long-term complications versus 26.8% in group 2 (p = 0.022). Most notably there was significant improvement in the incidence of ureteroenteric anastomotic strictures when comparing groups 1 (11.2%) and 2 (5.2%) (p = 0.006).
