Transurethral incision of the prostate (TUIP) is a minimally invasive surgical procedure used to treat urinary symptoms caused by an enlarged prostate, also known as benign prostatic hyperplasia (BPH). The procedure involves making small incisions in the prostate gland to relieve pressure on the urethra (the tube that carries urine from the bladder to the outside of the body), allowing for improved urine flow and reduced urinary symptoms.
