Transurethral laser incision of the prostate or TULIP is similar to transurethral incision of the prostate (TUIP), except the surgeon inserts a laser into the urethra, in order to make incisions in the prostate. The incisions open the urethra, so that urine can flow more easily from the bladder.

The advantages of this procedure over transurethral resection of the prostate (TURP) include:

• Decreased bleeding
• Shorter hospital stay
• Lower risk of impotence
