title: Intradiverticular bladder cancer: CT imaging features and their association with clinical outcomes.
abstract: OBJECTIVE
  To evaluate if computed tomographic (CT) features of intradiverticular bladder cancer can predict clinical outcome.
  
  
  METHODS
  Retrospective study of 34 patients with intradiverticular bladder cancer. Two radiologists independently evaluated all CT exams.
  
  
  RESULTS
  CT tumor length and width were significantly associated with survival for both readers [hazard ratios (HRs) 1.31-1.62, P<.001-.043]. No other tumor features were significantly associated with survival. The interreader agreement for the assessment of CT features was fair to substantial (k=0.34-0.78, concordance correlation coefficient=0.56-0.66). There was no association between transurethral resection pathology stage and survival (HR 2.10, P=.21).
  
  
  CONCLUSIONS
  In patients with intradiverticular bladder cancer, the tumor length and width measured on the pretreatment CT predicted survival.
