 Holmium laser inucleation of the prostrate, whole lip, is a procedure performed to remove tissue blocking the urine flow through the prostate. Pre procedure, the doctor may ask you to stop certain medications a few days before the surgery. You may also be recommended a 6 hour fast before the procedure. On the day of the procedure, you are administered anesthesia after which a surgical instrument called a resector scope is inserted through the urethra. The laser is inserted into the resector scope and is used to free up the enlarged prostrate tissue from the capsule and to seal up any blood vessels. The tissue that has been removed is deposited in the bladder. The laser is removed from the resector scope. When tissue removal is complete, the resector scope is withdrawn and a urinary catheter is put in place. The procedure takes 1 to 2 hours. Post procedure, you remain in the hospital overnight for observation and catheter care.
