This is a surgical procedure used most often to treat men with benign prostatic hyperplasia or BPH. The operation removes part of the prostate gland surrounding and constricting the urethra, the tube that takes urine from the bladder through the penis and out of the body. A tool with wire loop on the end is passed into the penis and through the urethra to the prostate gland. Electricity is then passed through the wire to heat it and cut the tissue. A representative sample of the prostate tissue removed during TURP is examined by a pathologist to determine whether any cancer is present. Although, BPH is not malignant, it is possible for BPH and prostate cancer to exist within the same prostate gland at the same time.
