Similar to TURP, this procedure is done through an instrument inserted through the urinary passage and the Bladder tumour is resected. Commonly done for suspected or proven bladder cancers, it is rarely done for patients with lesions in the bladder for the sake of achieving a diagnosis. The removed tissues are sent for the histological diagnosis. After the procedure, in some patients, catheter is inserted which remains inside for a short while. This is subsequently removed. In some patients a chemical ( chemotherapeutic drug or BCG) might be instilled inside the bladder.
