A shock wave is an ultrasonic wave that penetrates aqueous environments without significant loss, such as soft, well-hydrated, and low-density tissues like the kidney. Upon encountering a dense object, such as a kidney stone, the ultrasonic waves will reflect off it. Ultrasonic wave pulses are focused at a so-called focus, a point in space where the ultrasonic wave has the greatest force to disintegrate the stone. The procedure is performed at a frequency of 60-120 pulses per minute, with 1,500-3,000 pulses throughout the entire procedure. An ultrasound machine or a C-arm X-ray machine is used to position the stone. Thanks to the use of a high-quality video path with a monitored view, ionizing radiation doses are minimized.
Advantages of electroconductive technology:
1. Electroconductive shock wave generation. A uniform, precise electrical discharge generates a nearly identical shock wave pulse (therapeutic wave).
2. A built-in hydrophone inside the reflector measures the shock wave pressure, and a special system corrects the voltage values to match the power set by the lithotripter user.
3. Dual localization and imaging system, i.e., ultrasound and X-ray. Even non-opaque stones can be targeted.
4. The small focal point and precisely controlled shock wave generation environment mean that 90% of patients with a normal pain threshold do not require premedication. This increases patient comfort and reduces hospital costs.
5. Power adjustment from 1-100% power in one-percent increments allows for the procedure to be performed on children, as the physical properties of electroconductive technology allow for a highly flexible treatment protocol.
6. Equal conditions for every patient, ensuring safety. A hydrophone built into the reflector measures and regulates pressure in real time to the required value during each subsequent shot. This process is designed to maintain a constant level of effectiveness and fragmentation during subsequent treatments and to ensure greater patient safety.
7. Maximum shock wave pressure at its focus. The shock wave is generated directly at a geometric point with the same intensity with each shot. The shock wave is focused in an ellipsoidal reflector specifically designed to maximize the benefits of electroconductive technology.
