PRIMARY STUDY OBJECTIVE:

• To compare the recurrence rate at 1 year following Narrow Band Imaging and TURB (Arm A) with White Light Trans Urethral Resection of Bladder cancer (TURB) (Arm B) in patients with bladder cancer (NMIBC)

SECONDARY STUDY OBJECTIVES:

• To assess the persistence/recurrence of tumour at first follow up (3 months) after Narrow Band Imaging and TURB or White Light TURB in patients with NMIBC

• To assess the peri-operative morbidity (30 days) of TURB between NBI and WL resection by using the Clavien score

• To define risk factors for the development of peri-operative morbidity after instrumental treatment

• To assess the recurrence rate related to the surgeon performing the procedure

• To assess the recurrence rate related to additional treatment following TURB
