Laser prostatectomy accomplishes the same destruction of prostate tissue as the classic surgical way of treating prostate enlargement or BPH, a transurethral resection of the prostate, or TURP. However, where the TURP involves using a special telescopic electric knife to scrape out part of the prostate the laser is used to destroy the prostate tissue with heat rather than scrape it out. The entire prostate is NOT removed in this operation, but only that portion which is obstructing the channel. The procedure requires anesthesia and takes approximately 45-60 minutes to complete.
Preparation for the Operation
You may need blood tests, cardiograms, and other tests done prior to your surgical date, or on the morning of admission. It is very important that you refrain from eating or drinking anything for at least eight hours prior to your scheduled operation time. In most circumstances this means nothing should pass your lips after midnight the night before your surgical procedure. Aspirin, ibuprofen, coumadin, and other blood thinners need NOT be stopped for Laser Prostatectomy but it may be preferable to do so if possible.
Foley Catheter
After Laser Prostatectomy this tube or 'catheter' will be placed through your penis, through the prostate channel and into your bladder. It is held in position by a small balloon at the end of the tube which is inflated after it is placed. This tube or 'catheter' that is in the bladder is very important for your early post-operative recovery. It essentially puts the bladder and prostate at rest, and if there is any bleeding it allows the blood to come out immediately rather than staying in the bladder and prostate to form clots. Occasionally clots may form and the tube may stop draining. A special syringe with water can be used to hand irrigate the catheter to free it of clots. Hand irrigation is unlikely to be needed after KTP Laser Prostatectomy.
Post-operative Care
In most instances you will be able to eat a regular meal on the evening of surgery. You may go home the evening of surgery or stay overnight in the hospital, depending on the circumstances of your case. You should refrain from any unnecessary activity while the catheter is in place. Your usual medications may be restarted immediately after the surgery (Aspirin, ibuprofen, coumadin, and other blood thinners should be held if possible until after the catheter is out).
Post Operative Expectations
You may continue to have voiding symptoms for a variable amount of time, and this includes getting up at night, frequency, some hesitancy and blood in the urine. You may also have irritation and burning with urination for a limited amount of time after the surgery as the urethral lining heals. It may take as long as six to eight weeks to get a better idea of how successful the operation might be, depending on how much damage was done to the bladder wall by the obstruction of the prostate before the operation.
After Discharge to Home from the Hospital
The laser generally creates less post-op irritation than classic TURP. But some patients, after Laser Prostatectomy, have a brief period of irritative voiding symptoms. Because of the raw surface around your prostate and the irritating effects of urine, you may have frequency of urination and/or urgency (a stronger desire to urinate) and perhaps even more getting up at night. This will resolve or improve quickly over the healing period. You may experience clear urine for a few weeks then a sudden surge of blood in the urine, especially at about the third to fourth week post-op. This is often part of normal uretural healing after KTP laser. Refrain from strenuous activity and push fluids until clearing occurs.
Risks
Laser Prostatectomy provides long-term improvement of male voiding dysfunction in 80% of cases. Retrograde ejaculation (when you ejaculate the ejaculate travels up into the bladder) can occur at 10-20% (see sexual activity below) of the time and many may see decreased ejaculate volume. Most patients have irritation and discomfort with voiding for 1-2 weeks following Laser Prostatectomy.

Diet
You may return to your normal diet immediately. Because of the raw surface of the prostate alcohol, spicy foods and drinks with caffeine may cause some irritation or frequency and should be used in moderation. To keep your urine flowing freely and to avoid constipation, drink plenty of fluids during the day (8 - 10 glasses).
Activity
Your physical activity is to be restricted, especially during the first two weeks. During this time you should not lift heavy objects (anything greater than 20 lbs), drive a car or take long car rides, perform strenuous exercise, or engage in sexual intercourse. Minimize severe straining during bowel movements by using a laxative if necessary.
Sexual Activity
If you were sexually active prior to your surgery, you can resume normal sexual activity after 2 weeks. Resection of the prostate usually has little effect on a man's potency, orgasm, or ability to sense orgasm. There is a <1% risk of erectile dysfunction from Laser Prostatectomy. There may initially be some burning with ejaculation.
Because the junction of the bladder and prostate is involved in the operation, a decreased amount of seminal fluid can be expected to be ejaculated with sexual intercourse. In roughly 10-20% of cases there will be no ejaculate fluid with orgasm. There may be retrograde ejaculation. With retrograde ejaculation the orgasm occurs as usual but with ejaculation the sperm will enter the bladder but not exit through the urethra.
Bowels
It is important to keep your bowels regular during the post-operative period. The rectum and the prostate are next to each other and any very large and hard stools that require straining to pass can cause bleeding. You will be given stool softeners (usually) but these are not laxatives. A bowel movement every other day is reasonable. Use a mild laxative if needed and call if you are having problems. (Milk of Magnesia 2-3 Tablespoons, or 2 Dulcolax tablets for example).
Foley
The Foley catheter will drain into a bag on your leg. This bag can be simply drained by opening a valve at the bottom of the bag. Your catheter can be removed in the office 2-5 days after surgery. The work on your prostate as well as the indwelling catheter will cause the bladder to have sudden contractions, even with an empty bladder. These contractions are called bladder spasms and can be effectively managed by a medication to quiet bladder spasms. Medications that quiet bladder spasms are anticholinergic medications such as Ditropan. Anticholinergic medications can also slow down intestinal and salivary gland activity; therefore, side effects include constipation and dry mouth.
Medication
You should resume your pre-surgery medication unless told not to. In addition you will often be given an antibiotic to prevent infection and stool softeners. These should be taken as prescribed until the bottles are finished unless you are having an unusual reaction to one of the medications.
Problems You should Report To Us
- Fevers over 101.5 Fahrenheit
- Heavy bleeding, or clots that block the catheter (See notes above about blood in urine)
- Inability to urinate
- Drug reactions, hives, rash, nausea, vomiting, diarrhea
- Severe burning or pain with urination that is not improving.
Follow up
You will need a follow-up appointment to remove your Foley catheter.
Call 302-836-5500 to make this appointment for about 3-5 days after surgery.
