What does this procedure involve?

Transurethral Resection of Bladder Tumor (TURBT) is a minimally invasive endoscopic surgery performed under general or spinal anesthesia. A resectoscope is inserted through the urethra into the bladder to visualize and remove abnormal tissue, typically for non-muscle-invasive bladder cancer. The tumor is shaved off layer by layer, and the base is cauterized to control bleeding. Tissue samples are sent for pathological analysis to confirm diagnosis and staging.
