Urine cytology after flexible cystoscopy

OBJECTIVE: To correlate urine cytology findings before and after flexible cystoscopy. PATIENTS AND 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.
