Transurethral resection of the bladder tumor (TURBT) is a minimally invasive surgical procedure used to diagnose and treat bladder tumors. During the procedure, a thin tube called a cystoscope is inserted through the urethra into the bladder. The surgeon then removes the tumor using specialized instruments, allowing for both treatment and examination of the tumor. TURBT is typically performed under local or general anesthesia and may be done on an outpatient basis. This procedure helps to determine the type and stage of the tumor, guiding further treatment options such as chemotherapy or radiation therapy if necessary.
