Evaluation of the Value of Combined Urine Cytology and Cystoscopy for Follow-up of Superficial Transitional Cell Carcinoma of the Urinary Bladder.

Objective: Cystoscopic biopsy is the most accurate technique used to assess the efficacy of treatment and to detect recurrence of superficial TCC of urinary bladder. Implementation of voided urine cytology to detect tumor cells in urine samples may represent an additional tool. The aims of this study are: (1) To estimate the reliability of combined cystoscopy and urine cytology examination in the follow-up of cases of superficial urinary bladder carcinoma, which might help to restrict cystoscopic biopsies for these cases with its morbidity and cost, (2) To discuss the diagnostic pitfalls of cytologic examination in these cases.
