1. Extracorporal, stone fragmentation by external shock-wave

At treatment of kidney stones our technical staff starts-up the lithotripter transported to the urological ward of contractor hospital, and the trained doctor performs the treatment in approx. 20 minutes at site.

Operation principle
By generation of electronic shock-wave the effected shock-wave is focused, and then the one-point concentrated energy, originating as pressure, is directed to the kidney stone of the patient. This shock-wave effects perfect stone-decomposition, which - in the contrary of other types - does not effects sharp, larger pieces, only small, sand-size particles.
Advantages of treatment and optional complications
There are three methods for nephrolith removal which could be applied:
  1. open operation, which means a well established operation technique from the last century, its disadvantage is that it can not be repeated unlimited.
  2. percutan endoscopic kidney stone removal, which has shorter healing period, in case of experiences hands with minor complication, quick rehabilitation but also operation technique, bloody procedure, with known complications of operation and anaesthesia.
  3. shock wave, the most significant medical accomplishment of last decade.

The principle is that an external high energy - focused appropriately - with proper transmission medium can be lead into human body and in proper way with ultrasonic or X-ray targeting the focus-point fixed onto the nephrolith, the evolving energy causes stresses, the kidney stone disrupts as a consequence of repeated impulses, and finally leaves the body via the urinary tracts.

The only disadvantage of shock-wave treatment is the high investment cost of lithotripter. In counties with developed health-care the shock-wave lithotripsy (ESWL) is the effective alternative of open or endoscopic kidney stone operations, having very low complication level.

It can be applied in 60-70 % of stone-removal cases as a monotherapy. In further 20-25% is proven as effective complementary treatment of different adjuvant endoscopic or percutan treatments or in combination with these. The AVAS Medical Centre performs ESWL treatments in following hospitals:

2. Digital intervention radiology

It is basically X-ray diagnostic of vasoconstriction patients after contrast material injection and/or for elimination of vasoconstriction of diagnosed patients after medical examination and found suitable for treatment.

  • Throat and lower limbs ultrasonic examinations (Color Doppler and dupley) in case of suspicion of vasoconstriction, after booking, with referral of family doctor or specialist

  • Catheter vein colouring examinations
    Primarily by vasoconstriction patients, if on the basis of preliminary examinations there is suspicion of vasoconstriction. For referral of vein-surgeon, angiologist, neurologist. The colouring of veins is necessary because on the basis of this it can be decided, what kind of therapy could be applied. The veins of throat, abdomen and limbs. Secondarily it can be applied for proving of vein-growing abnormalities, bleedings, occasionally tumours.

  • Intervention examinations
    In first instance it is a medical treatment with introduction of catheters into vein. In case of veins in limbs, throat and abdomen. Dilatation of narrowed veins (PTA), opening of obstructed veins, if necessary bridging by means of metal net (stent). Closing of veins (embolisation) in case of blooding and/or in case of tumour diseases closing of blood vessels supplying the tumour. In this latter case the closing can be achieved with combination of targeted injection of antitumour medicine (citostaticum) via the catheter, which is called chemoembolisation.
    Closing of veins is also possible with catheter. E.g. in case of orchiovaricotomy (varicocele), which effects total recovery.
    In case of closing or narrowing of bile passages there is also possibility of bridging of bile passages by means of metal net (stent), which effects recovery.
