The purpose of the work was to evaluate the influence of the use of fluorescence cytoscopy (FC) during transurethral resection (TUR) on the rate of recurrences of external urothelial urinary bladder carcinomas. The patients were randomized into two groups. In the first group the TUR was made in a standard way, while in the second one it was made under the control of FC. The patients were further monitored in standard way, evaluating the rate of recurrences. From September 2001 to September 2003 there were 99 patients involved in total, 49 of them to the first group and 50 to the second group. At the first control cystoscopy the positive finding was found at 17 patients (34,7 %) in first group, respectively at 4 (8%) in the second one. Lower risk of recurrence at patients where FC was used is evident during the first year after operation (p = 0,0573, Wilcoxons generalizing test), while during longer observation the rate of recurrences in the both groups does not significantly differ (p = 0,1427, Log-Rank test). The use of FC during TUR of external urinary bladder tumour lowers the risk of early recurrences of the disease.
