| Assessment | |
| Primary outcomes | All lesions must be histological confirmed.
The proportion of subjects with histology-confirmed tumours (Ta or T1) who have at least one such tumor found by NBI but not by white light cystoscopy. Comparison of the proportions of Group A and Group B subjects who undergo TURB for a histology-confirmed Ta or T1 tumour who have a recurrence (histology confirmed Ta or T1) found at either three or twelve months. |

| Interventions/Control_1 | All patients in Group A will be treated with WL and NBI. The surgeon performing the follow up must preferably be different from the one performing the TURB. Patients will be followed during hospital stay, after 3 and 12 months at a minimum depending on stage and grade of tumours. All positive or suspect areas will be resected/biopsied using WL or NBI technique. The whole procedure will be recorded. At three months follow up patients will undergo WL cystoscopy and possible recurrence will be searched for and need histological confirmation. The study is designed to disclose a reduced recurrence rate at 1 year (estimated 10%) in the group treated by NBI TURB compared to the control group, treated by WL TURB. | |
| Interventions/Control_2 | All patients in Group B will be treated with WL. The surgeon performing the follow up must preferably be different from the one performing the TURB. Patients will be followed during hospital stay, after 3 and 12 months at a minimum depending on stage and grade of tumours. All positive or suspect areas will be resected/biopsied using WL technique. The whole procedure will be recorded. At three months follow up patients will undergo WL cystoscopy and possible recurrence will be searched for and need histological confirmation. The study is designed to disclose a reduced recurrence rate at 1 year (estimated 10%) in the group treated by NBI TURB compared to the control group, treated by WL TURB. | |

| Key inclusion criteria | Patients scheduled for treatment of a primary NMIBC
Patients should be aged 18 years or older No tumours in the upper urinary tract No previous irradiation of the pelvis |
|||
| Key exclusion criteria | Gross hematuria at the time of TURB. (Note: Gross hematuria is defined as a heavy bladder bleeding resulting in marked amounts of blood in the urine, which may interfere with cystoscopy).
Participation in other clinical studies with investigational drugs either concurrently or within the last 30 days. Pregnant or breast-feeding (all women of child-bearing potential must document a negative serum or urine pregnancy test at screening and use the contraceptive pill or intrauterine device (IUD) during the treatments and for at least one month thereafter). Why, we do not inject anything |
