One hour prior to the treatment the patient will have Hexvix® (photodynamic substance) and Lidocaine 20 ml (pain treatment) installed in the bladder. Simultaneous pain treatment will be oral Paracetamol 1 g and Ibuprofen 600 mg. Biopsy from the tumor will be taken to confirm the histological diagnosis.\n\nImmediately after the procedure the pain assessed by the VAS score will be recorded and the patients are given a QOL questionnaire (EORTC QLQ-BLS24) and a stamped envelope and are asked to return it one week later. The patients will be telephoned after 5 days to remind on the questionnaire and to ash, whether they has had a urinary infection after the procedure.\n\nOne 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.
