BPH surgery using laser procedures

With the laser, the tissue is "evaporated".
As the thermal process and the various laser procedures are based on the principle of heat transfer. The heat causes the tissue, depending on the intensity of the laser, its method of use or focusing the radiation to evaporation (vaporization), charring (carbonization) or denaturation of the tissue.


Depending on the requirement of different techniques are used.
We distinguish between three techniques:

     The non-contact technique in which the laser radiation by mirrors and prisms is radiated into the tissue without damaging the instrument (urethroscope: Endoscope for mirroring the urethra) that comes into contact.
     The contact process in which heat is transferred through a urethroscope mounted on the probe tip.
     The interstitial process, are inserted in the specially prepared tips under visual control into the prostate tissue where they exert their effect.


Advantages and disadvantages must be weighed against each other.
The strength of these methods is that they are more gentle and less invasive. The operation times are compared with the TURP unbeatable short and low risk of bleeding. The attractiveness of this method lies primarily in the ability to perform them without anesthesia. This almost disappears, the anesthetic risk of surgery, which is primarily for older patients at risk and victims of advantage. Disadvantages of these methods are both high cost (laser therapy) and sometimes after months of onset of improvement in symptoms. In laser treatment, it comes through the application of heat in heat necrosis of the bladder neck, which must then be repelled. This process usually takes several weeks to complete. During this period, the patient can only drain his bladder through a catheter.
