MODEL RELEASED. Bladder cancer surgery. Endoscope view of an electrocautery (burning) wire loop being used during a transurethral resection of a bladder tumour (TURBT) on a patient with cancer of the bladder lining. The surgeon is viewing and accessing the bladder through a cystoscope, which is inserted in the patient's urethra, the tube that carries urine from the bladder out of the body. This is minimally invasive, or keyhole, surgery and requires minimal aftercare. For the entire sequence see clips K002/9557 to K002/9577.
