Narrow Band Imaging and PDD in Cystoscopy Clinical Trial
Official title:
Trimodalitets-studie Hvidt Lys vs. NBI vs. PDD Ved Detektion af Flad Dysplasi og CIS Ved TURB
All patients planned for PDD guided TURB can be included in this study. Two different optics
with PDD and NBI are applied to the resectoscope in addition to regular WL.
First, a WL cystoscopy is made and any suspect areas are noted on the registration form,
then NBI is used and any suspect areas are noted and finally the cystoscopy is made with PDD
with registration of any additional findings. To adjust for bias introduced by photo
bleaching, the second part of the study will be performed with PDD as the second modality.
Any flat lesions will be biopsied if they appear suspicious in one of the modalities.
The registration form is completed by the surgeon, once the pathology results are known.
A total number of 152 patients is planned to be included.
