A Single Instillation of Epirubicin After Transurethral Resection of Bladder Tumors Prevents Only Small Recurrences

We confirmed the results of previous studies showing that 8.5 patients must be treated with a single instillation to prevent 1 recurrence. Furthermore, our data may indicate that only small recurrences are prevented, which could easily be fulgurated using local anesthesia at followup cystoscopy. The benefit of single instillations can be questioned if this finding is confirmed by others.
