The purpose with this clinical investigation is to perform Raman spectroscopy inside the vivid bladder and to acquire Raman spectra of normal and tumour bladder tissue, and in a post-processing step to determine the grade of the tumor.
The purpose with this clinical investigation is to perform Raman spectroscopy inside the vivid bladder and to acquire Raman spectra of normal and tumour bladder tissue, and in a post-processing step to determine the grade of the bladder tumor.
The recordings and overall results will be compared to standard histo/cytopathological examination of urological tissue to achieve a clinical useful concordance between gold standard histo/cytopathological diagnosis and diagnostic information established by Raman.
The MIB RAMAN SYSTEM in combination with a Raman probe will be used in the operating theatre at Herlev/Copenhagen hospital urology department, where the rigid resectoscopes will be used while the trial participant is under general anesthesia. Each measurement takes about 1-5 seconds and the whole procedure with the fiber optic probes is expected to prolong the operation with 10-15 minutes.

Inclusion Criteria:
After booking for surgery the trial participants will be informed orally about the study and written material will be given by a doctor or nurse form the study group. If the trial participant accept to enter the study, written informed consent will be obtained. The trial participant will be informed that they can withdraw the informed consent at any time and the treatment will be according to the guidelines of the department.
