 One month after the laser TURBT a flexible PPD and SPIES guided cystoscopy is performed in the OPD to evaluate the laser efficacy. To confirm that all tumour tissue has been removed a biopsy will be taken from the previous tumor place. The biopsy will be send to the pathologist according to the normal procedure for biopsies. Visual presentation of the laser treated area will be visualized using PDD and SPIES.
