We can precisely resect visible lesions, because each lesion shines red in UV. Materials and Methods\: A total of 80. patients with known bladder cancer in stages Ta, Tis or T1 and grade G1\-G3, half of the patients or suspected bladder cancer, half of the patients diagnosed by hematuria, ultrasonography, urography were recruited. Patients underwent bladder instillation with 50 ml of 8 mM solution of HAL hydrochloride in phosphate buffered saline Hexvix through a Foley catheter. The solution was retained for at least 1 hour before cystoscopy. Cystoscopy was performed using spinal or general anesthesia. After the HAL solution was evacuated the bladder was inspected by white light cystoscopy. Lesions or suspicious areas were classified and mapped onto bladder chart by blue colour. The bladder was then inspected by HAL fluorescence cystoscopy. Lesions or suspicious areas were classified and mapped onto bladder chart by red colour. Fluorescence cystoscopy was a supplementary procedure but not substitutional procedure. Biopsies were taken from all mapped areas. We took also biopsies from the tumours base for correct staging. Standard and HAL fluorescence cystoscopy was performed using the Storz D\-light system and fluorescence\-capable telescopes, whic"]
