Laser Prostatectomy


Laser prostatectomy is a surgery that uses light beams to destroy part of the prostate gland. This can help reduce urinary problems caused by an enlarged prostate.

The week before your surgery:

  • Write down the correct date, time, and location of your surgery.
  • Arrange a ride home. Ask a family member or friend to drive you home after your surgery or procedure. Do not drive yourself home.
  • Ask your healthcare provider if you need to stop using aspirin or any other prescribed or over-the-counter medicine before your procedure or surgery.
  • Bring your medicine bottles or a list of your medicines when you see your healthcare provider. Tell your provider if you are allergic to any medicine. Tell your provider if you use any herbs, food supplements, or over-the-counter medicine.
  • You may need blood or urine tests before your surgery. You may also need x-rays, an EKG, ultrasound, cytoscopy, or prostate biopsy. Talk to your healthcare provider about these or other tests you may need. Write down the date, time, and location for each test.

The night before your surgery:

  • Ask healthcare providers about directions for eating and drinking.
  • You may be given medicine or an enema that will empty your bowel.

The day of your surgery:

  • Ask your healthcare provider before you take any medicine on the day of your surgery. Bring a list of all the medicines you take, or your pill bottles, with you to the hospital. Providers will check that your medicines will not interact poorly with the medicine you need for surgery.
  • You or a close family member will be asked to sign a legal document called a consent form. It gives healthcare providers permission to do the procedure or surgery. It also explains the problems that may happen, and your choices. Make sure all your questions are answered before you sign this form.
  • Healthcare providers may insert an intravenous tube (IV) into your vein. A vein in the arm is usually chosen. Through the IV tube, you may be given liquids and medicine.
  • An anesthesiologist will talk to you before your surgery. You may need medicine to keep you asleep or numb an area of your body during surgery. Tell healthcare providers if you or anyone in your family has had a problem with anesthesia in the past.


What will happen:

Your surgeon will insert a scope into your penis through your urethra. He will use the scope to find the narrowed part of your urethra that the prostate blocks. He will make an incision in the urethra to reach the prostate. Your surgeon will use a laser to destroy excess prostate tissue. He may remove a part of your prostate and pass it into your bladder. Once the piece of your prostate is inside your bladder, it will be broken into tiny pieces. These pieces of prostate will be removed or left in your bladder to be passed out in your urine. Your surgeon may also use the laser to seal blood vessels and stop any bleeding. He will place a urinary catheter to help drain your urine.

After your surgery:

You will be taken to a room to rest until you are fully awake. Healthcare providers will monitor you closely for any problems. Do not get out of bed until your healthcare provider says it is okay. When your healthcare provider sees that you are okay, you will be able to go home or be taken to your hospital room.


  • You cannot make it to your surgery.
  • You have a fever.
  • You have questions or concerns about your surgery.

Seek Care Immediately if

  • You cannot urinate, or if you have a catheter, no urine is filling the bag.
  • You have lower abdominal pain or back pain that does not go away.
  • Your symptoms get worse or come back.
  • Your urine is red, cloudy, and foul smelling.


  • The laser may irritate or damage the tissue in and around your prostate. Nerves or blood vessels may be damaged, which may lead to problems urinating or having an erection. Your surgeon may need to make a larger incision than expected during surgery. Even with surgery, your prostate may become enlarged again and you may have problems urinating.
  • Without treatment, your prostate may continue to grow. You may not be able to pass urine. You may get infections that may damage your urinary tract, especially your kidneys. These may lead to more serious and life-threatening problems, such as heart, liver, or brain damage.
