Transurethral resection of bladder tumor (TURBT) is the endoscopic removal of tumors inside the bladder. Most bladder tumors are cancerous and have to be resected completely.
Under general or spinal anesthesia, a resectoscope (loop-cutting instrument) is passed through the urethra. The bladder tumor is resected completely and separate biopsies are taken from the base to see if it has invaded into the bladder muscle. A catheter is inserted into the bladder after the surgery for irrigation and to prevent blood clots from forming.
