Thulium Laser En-bloc Resection of Primary Non-muscle Invasive Bladder Cancer

The goal of this clinical trial is to know if thulium laser works to treat non-muscle invasive bladder cancer "NMIBC" efficiently in comparison to classical trans-urethral resection "TURBT". It will also learn about the safety of this technique. The main questions it aims to answer are: Does thulium laser lower the incidence of recurrence to participants with non- muscle invasive bladder cancer? What complications do participants have when using this technique? Investigators will compare thulium laser en-bloc resection to a classical trans-urethral en-bloc resection of bladder tumor Participants will: Do thulium laser en-bloc resection or trans-urethral en-bloc resection And will be classified to risk group according to European association of urology guidelines and followed up accordingly.
