Treating BPH with the Evolve Laser from Biolitec

When it comes to treating benign prostatic hyperplasia (BPH), among the tools we use at our clinic is a new laser method, one that is directed primarily at middle-aged patients for whom it is important to retain a full ejaculation even after treatment for their prostate disorder. This demands an extremely accurate and precise treatment of the prostate by laser, one that has now been made possible thanks to the so-called Evolve Laser method developed by the German company Biolitec based in Jena.

Evolve is a minimal-invasive procedure. Laser energy is used to remove obstructive prostate tissue from around the urethra that causes the symptoms usually associated with BPH.

The laser operates in the infrared range, and in this method uses two wavelengths of 1470 and 980 nanometers (nm) running in parallel. This has the advantage that an optimal absorption is achieved in water and hemoglobin, which in turn means a high rate of ablation in combination with a good hemostatic (blood-staunching) effect. In plain text: the proliferative prostate tissue is swiftly and effectively ablated and the free off-flow of retained urine is completely restored.
The Evolve Laser also ensures that the internal structures of the prostate gland that enable ejaculation are spared. Thus, for the very first time there is now a method available that enables so-called retrograde ejaculation to be prevented. In particular middle-aged men between 40 and 50 years of age who may still have the wish to sire children can draw new hope even if they are suffering from BPH.
The excellent hemostatic profile has a positive impact on the healing process: there is virtually no loss of blood, and the surrounding tissue is spared. The patient experiences relief directly following the treatment and no longer feels the constant and uncomfortable urge to urinate.

What is so special about Evolve Laser?

The invisible infrared laser beam is led through a specially shaped glass-fiber light conductor directly to where it is needed. Here the smoothed tip of the instrument comes into contact with the tissue and hence achieves an extremely high degree of ablation compared with conventional laser methods.
The new treatment method is also suited for high-risk patients, since there is no longer any need for strong anesthesis, and any anticoagulation medication that these patients are often obliged to take can be recontinued a short time after the treatment.

What are the benefits of the Evolve Laser for the patient?

  • Safe and minimal-invasive treatment
  • Short duration of treatment
  • Immediate results
  • Minimal side-effects or complaints following treatment
  • In most cases no impact on sexuality and continence
  • Swifter reconvalescence
  • Additional safety thanks to microsurgical precision
  • Treatment possible both on an inpatient and outpatient basis
  • Postsurgical catheterization is in many cases necessary only for a short time or not at all
  • Very short stay in the clinic (in most cases just one night under observation)

The typical course of treatment

A healthy prostate gland is roughly the same size and shape as a walnut and weighs approximately 30 grams. When the prostate is enlarged, this constricts the urethra, resulting in an impaired off-flow of the urine.
This image shows the prostate in enlargement and from the side.
The treatment commences by inserting the probe upwards through the urethra.
The head of the probe is pushed out of the probe.
Infrared light invisible to the human eye is discharged from the probe head.
The operator steers the probe, rotating it to ablate the tissue in a circular motion.
The entire probe is gradually retracted.
The funnel grows larger step by step.
At the end of the treatment the probe is completely withdrawn from the prostate.
Urine can once again flow off freely.

Questions on the topic of Evolve Laser treatment

What course does treatment with the Evolve Laser method take?

  • Prior to the treatment of BPH the physician performs examinations to decide which form of therapy is suited for which type of patient.
  • The physician may prescribe oral tranquilizers or other drugs to prevent infections.
  • You are given a local anesthetic.Once the anesthetic takes effect, the urologist inserts a cystoscope into your urethra.
  • Using the Evolve probe the physician systematically vaporizes the excessive prostate tissue until the obstruction has been completely removed.
  • Following the treatment, it may be necessary for the physician to insert a catheter for a short time to allow the urine to flow from the bladder into a bag attached to your leg.

What effects must I anticipate following treatment?

It may be necessary to insert a bladder catheter after the treatment. In most cases, this is removed again 24 to 48 hours later. Most patients experience relief of their symptoms and a substantial improvement in their ability to pass urine very soon after the treatment.
For about one week you may experience slight complaints when passing urine, detect minute traces of blood in your urine, or still have a slightly raised urge to urinate. These symptoms will, however, soon recede again, since your bladder will require a little time to "accustom" itself to the fact that the obstruction in your urethra is no longer there.

Must I stay in the clinic following the Evolve Laser treatment?

Most men are discharged from the clinic very soon, in most cases the following day.

Will the laser therapy impact my sex life?

In theory, every surgical intervention involving the prostate can result in an impairment of sexual function. If, however, you have been sexually active prior to the procedure, it is highly probable that your sexual activity will not be impaired following the treatment. At this point it should be mentioned that of all the treatment methods involving the ablation of prostate tissue, laser vaporization is the one associated with the lowest rate of sexual function impairments.

How long does it last until the symptoms recede?

Most patients experience relief of their symptoms and a substantial improvement in their ability to pass urine very soon after the treatment - in most cases within the space of 24 hours. Certain factors, such as other health disorders in the patient's medical history and his current state of health, may, however, have an effect on the treatment and reconvalescence.

Will I have to take other drugs against BPH after treatment with the Evolve Laser method?

Your physician will decide which form of therapy is best in your particular case. In most cases, however, patients can stop taking their other BPH medication a few weeks after the treatment.

When will I be able to return to my job?

As a rule, activities involving relatively little physical exertion, such as e.g. office work or driving a car can be resumed after just a few days. Physically demanding work and sexual activities can normally be resumed after two to three weeks.
