Operating Room / Surgical Procedures

When it is time for a procedure due to patient preference, failure of medical management, or if complications of enlarged prostate or BPH have occurred, it may be necessary to offer a more aggressive procedure that will have to be done in the operating room under anesthesia. All procedures in this class share the main characteristic that here tissue will actually be removed from the middle of the prostate in order to unobstruct the bladder. The best way to explain this is to understand that in the aging male the prostate can be thought of as a navel orange, with a thick peel surrounding the pulp. It is the pulp that grows as a man ages.

The bladder must empty through the inside of the prostate, the bladder has a hard time emptying as this “pulp” grows and starts to occlude the urine channel. This is why in more severe cases of BPH the bladder simply cannot empty and why it is sometimes necessary to completely “open up the plumbing” to fix the problem.

These procedures only remove the inner overgrown core, not the periphery of the prostate, and they are not to be confused with complete removal of the prostate, or Robotic Prostatectomy, as is necessary in the case of cancer. They also do not carry with them the same risks and post-operative problems that cancer surgery will.

Bipolar TURP

The gold standard procedure in this category is now and has always been called a Trans-Urethral Resection of the Prostate, or TURP. TURPs have been performed for over 50 years. Before medicine for BPH existed, it was for many years, the most commonly performed surgery other than cataract surgery in America. The TURP has become much safer with the advent of bipolar technology, which allows the use of saline rather than water as the irrigant. Using water in the past always created a risk of diluting the blood and lowering key electrolyte concentrations that could lead to significant complications. This tended to limit how long a surgeon had to perform a TURP, and thus the size of prostate that could be operated on in one sitting. With saline, the operation is far safer, and larger prostates can be treated. A TURP will require:

  • Either general or spinal anesthesia
  • Typically, a one day hospitalization
  • A 3-5 day period of catheterization.

It is not particularly painful, and if applied to the right patients should produce at least a 93%-95% success rate. However, a TURP also has a low, but present risk (1% or less) of post-operative incontinence which will have to be surgically fixed, the risk of bleeding or other anatomic complications, and the near certain fact that patients will not have semen when they ejaculate after the procedure. So, even though a TURP is extremely effective and usually very well tolerated, there is also increased risk when compared to office procedures. It is for this reason that Urologic Surgeons of Washington offer treatments in a stepwise fashion. But, when a more aggressive treatment is called for, a TURP is the treatment of choice.

Robotic Simple Prostatectomy

Occasionally however, the prostate might be simply too large to perform a TURP efficaciously and safely. Generally, the goal is to perform the procedure that will be the safest and most effective with the least risk that will allow removal of the inner prostate tissue. As the prostate size approached 100 grams, especially if there are other complication factors such as the presence of bladder stones, what will be offered is a different operation called a Robotic Simple Prostatectomy. Traditionally this has been performed through an incision in the lower abdomen, whereby an incision is made in the bladder that allows the surgeon to tease out the “pulp” of the prostate in one perfect piece, just as one might use their finger to remove the peel of a large navel orange. However, now Dr. Engel will utilize that advantages of robotic surgery to perform this operation. This will allow for a more elegant, less bloody operation and faster recovery. This operation is performed under general anesthesia, and will also require a one night hospital stay and a 3-5 day catheterization. It will have an identical risk profile to the bipolar TURP.

HOLEP / Holmium Laser Enucleation of the Prostate

Another procedure that is gaining some popularity and is applied by some surgeons for large prostates is called HOLEP, or Holmium laser enucleation of the prostate. This is done under anesthesia, and in the right hands can achieve what a Robotic Simple Prostatectomy achieves without an abdominal operation. However, this operation carrries with it a significantly higher risk of bleeding complications, and early reports suggest a higher risk of incontinence. It is for these reasons, as well as the fact that Dr. Engel is extremely experienced with robotic procedures, that this is not offered by Urologic Surgeons of Washington.

Greenlight Laser

Finally, also in the class of procedures that can remove tissue and require anesthesia and thus an operating room are laser procedures. Most heavily marketed, and thus perhaps most popular, has historically been the Greenlight Laser. However, several other wavelength lasers also achieve the same result including a Holmium laser (HOLAP) and others. With laser procedures, the inner prostate tissue, or adenoma, is not cut out but rather heated at such a high temperature that the tissue vaporizes. We consider these procedures very similar to the TURP in that the inside of the prostate is opened up. However, with such extreme heat there are generally far more irritative symptoms and also scarring complications that are usually not seen with TURP. A TURP will remove far more tissue than a laser procedure, with fewer complications, and will typically give more long term results. Thus, we find that laser procedures are best suited for patients who otherwise would be perfect candidates for office procedures, and we therefore see the logic in recommend these less invasive procedure in lieu of more aggressive laser procedures typically.

A laser procedure will have an identical risk profile to the TURP as well. One of the reasons for their popularity with some Urologists is the ability to perform these procedures in an outpatient surgery center as an outpatient, but again for the reasons stated above, we feel such a patient is best served typically with a safer, easier office procedure.

As usual, we at Urologic Surgeons of Washington partner with our patients. We offer all of the options and present all of the pros and cons of each, decide together which procedure, which degree of invasiveness, the patient’s willingness to tolerate risk, and which other medical considerations come into play before choosing how best to serve our patients urologic needs.
