[Bimodal and multimodal endoscopy of the urinary bladder in diagnosis and treatment]

White light cystoscopy is a precise instrument for the detection and treatment of papillary bladder tumors. Various additional macroscopic detection methods have been established. Some of them, especially PDD or NBI, have been shown to have an additional benefit on the recurrence rate of bladder tumors, so they should be used as part of the diagnosis and treatment when available. Other microscopic classification techniques or multimodality techniques are currently under development. Widespread use of these techniques is still pending. Newer modalities such as multi-parametric imaging or AI-assisted endoscopy promise a significant leap in innovation in the future and could ensure that real-time urological endoscopy is significantly advanced.
