During cystoscopy, a thin, hollow viewing tube, known as a cystoscope, is inserted into the urethra and then into the bladder to look for tumours and other abnormalities affecting the urethra and bladder. The cystoscope may be rigid or flexible. Instruments to take tissue samples or destroy or remove tumours and stones can be inserted through the cystoscope. The procedure may be carried out under local or general anaesthesia.
