title: Complications of radical cystectomy for nonmuscle invasive disease: comparison with muscle invasive disease.
abstract: OBJECTIVE
  Radical cystectomy is gold standard treatment for muscle invasive bladder cancer and is an option for many patients with nonmuscle invasive disease at high risk for disease progression. We assessed the early complications of radical cystectomy among patients with nonmuscle invasive compared to those with muscle invasive disease.
  
  
  METHODS
  We reviewed the records of 304 consecutive patients who underwent radical cystectomy from December 1995 to July 2000. We evaluated complications that occurred within 30 days of the procedure. Cases were stratified into nonmuscle invasive (PO, Pa, P1 and PIS, N0) or muscle invasive (P2-4, N0-3) tumors based on final specimen pathology. The 2 groups were then compared with respect to age, gender, race, American Society of Anesthesiologists score, type of urinary diversion, estimated blood loss, operative time and length of stay, and major and minor complications.
  
  
  RESULTS
  Of the 293 available patients 105 (36.8%) had nonmuscle invasive specimen pathology. Overall major and minor complications occurred in 4.9% and 30.4% of cases, respectively. Independent t test revealed no significant difference between groups in terms of age (p = 0.85), gender (p = 0.77), race (p = 1.0), American Society of Anesthesiologists (p = 0.32), type of urinary diversion (p = 0.33), estimated blood loss (p = 0.31), operative time (p = 0.41), length of stay (p = 0.75), or presence of major (p = 0.78) or minor (p = 0.79) complications.
  
  
  CONCLUSIONS
  The early morbidity associated with radical cystectomy for nonmuscle invasive disease is similar to but not less than that associated with muscle invasive tumors. These acceptable risks as well as the potential benefits should be discussed with patients with nonmuscle invasive bladder cancer at high risk for disease progression.
