"Samples for microbiome analysis:~Samples will be collected in clean leak-proof containers without disinfectant or detergent residue and with tight-fitting leak-proof lids and preserved in a refrigerator until be analyzed at the microbiology laboratory of TBRI.~Urine samples (50 ml) for microbiome analysis will be collected during cystoscopy examination. Samples will be stored at -80 °C until processing.~Tissue and urine samples from patients with bladder cancer: Under standard procedure of diagnostic cystoscopy urine sample will be collected under complete aseptic conditions, patients who has bladder tumor will undergo transurethral resection of bladder tumor, a tissue sample 0.5x0.5 cm will be investigated for microbiome analysis. Samples will be stored at -80 °C until processing. Histopathological diagnosis with Hematoxylin and eosin stain will be done by an expert pathologist for tumor grade and stage according to WHO 22, and EAU guidelines 2023. This procedure will be applied for"
