title: Urine cytology after flexible cystoscopy.
abstract: OBJECTIVE
  To correlate urine cytology findings before and after flexible cystoscopy.
  
  
  METHODS
  A total of 153 patients undergoing surveillance for bladder tumour provided voided urine for cytology before and immediately after flexible cystoscopy.
  
  
  RESULTS
  Of the 153 patients, 116 had negative urine cytology before and after (96%) a visibly normal cystoscopy and 37 had positive urine cytology before and after cystoscopy that showed recurrent tumour.
  
  
  CONCLUSIONS
  Urine cytology immediately after flexible cystoscopy correlates well with results of urine cytology before cystoscopy.
