Transurethral resection of the prostate (TURP) is a surgical procedure for benign prostatic hyperplasia (BPH) — a non-cancerous enlargement of the prostate that can block the flow of urine. During TURP, your surgeon passes a thin instrument called a resectoscope through the urethra (the tube that carries urine out of the bladder) — there is no cut or incision on the skin. Using a wire loop, the surgeon trims away the inner prostate tissue that is narrowing the channel, widening the passage so urine can flow normally again.
TURP has been used for decades and remains one of the most effective, durable treatments for moderate-to-large prostates causing bothersome symptoms — weak stream, frequent urination, getting up at night, straining to start, or a feeling of incomplete emptying.
TURP treats BPH, not prostate cancer
TURP removes the tissue blocking urine flow. It is not a treatment for prostate cancer, and it does not remove the outer capsule of the prostate gland.
