Transurethral Resection of Prostate is a surgery to remove the inside part of the prostate gland. It is done in order to treat symptoms of an enlarged prostate. The surgery takes about 1 hour. You will be given medicine before surgery so you don't feel pain. You may get general anesthesia in which you are asleep and pain-free or spinal anesthesia in which you are awake, but relaxed and pain-free. The surgeon will insert a scope through the tube that carries urine from your bladder out of the penis. This tube is called the urethra. A special cutting tool is placed through the scope. It is used to remove the inside part of your prostate gland using electricity.
