title: Value of urethral wash cytology in the retained male urethra after radical cystoprostatectomy.
abstract: OBJECTIVE
  We determined the outcome in patients who underwent urethrectomy after cystectomy followed by routine urethral wash cytology versus those not followed by urethral wash cytology who presented with bleeding or urethral discharge. We retrospectively evaluated the outcome in post-cystectomy urethrectomy cases at our institution from 1994 to 2000.
  
  
  METHODS
  A total of 24 patients with a median age of 70.5 years underwent urethrectomy after cystectomy, including 17 due to asymptomatic, positive urethral wash cytology (group 1) and 7 who were not followed by urethral wash and presented with bleeding/urethral discharge (group 2). Median time from cystectomy to urethrectomy was 11.4 months (range 6.7 to 67.1). Median followup after cystectomy and urethrectomy was 37 and 27.7 months, respectively.
  
  
  RESULTS
  Urethrectomy pathological evaluation showed pTis disease in cases 12 (50%), pT0 in 9 (37.5%) and pT1 in 3 (12.5%). Cystectomy pathology was organ confined (pT0, pTis and pT1-pT2b disease) in 12 cases (50%), nonorgan confined (pT3a-pT4) in 6 (25%) and pT any N1 in 5 (21%). Cystectomy pathology was unknown in 1 case. At the most recent followup there was no evidence of disease in 14 patients (58%), 5 (21%) were alive with disease, 3 (12.5%) were dead of disease, 1 (4%) was dead of other causes and disease status was unknown in 1 (4%). There was no statistical difference in survival in groups 1 and 2 when controlling for original bladder tumor stage. Cox regression analysis revealed that cystectomy pathology was the only statistically significant parameter of disease-free survival (p = 0.011), while urethrectomy pathology and followup method (urethral washing versus no washing) were not significant. There were no perioperative or postoperative complications and no patients died.
  
  
  CONCLUSIONS
  There was no significant survival difference in patients followed and not followed with urethral washing. Longer followup and increased patient numbers are needed to determine the significance of these findings.
