Burst wave lithotripsy produced consistent, small passable fragments through transcutaneous applications in a porcine model, while producing minimal injury and clinical trials are now underway. A more efficient ultrasonic propulsion design that can also deliver burst wave lithotripsy effectively repositioned 95% of stones in 18 human subjects

CONCLUSION. Ultrasonic propulsion of kidney stones is a safe, effective, and easy-to-learn method of transcutaneously repositioning stones within the kidney. The technology continues to be optimized, and future directions include fusion of the technology with BWL and stone-specific ultrasound imaging algorithms.

Ultrasound crushing of stones does not require significant preparation of the patient and therefore it is often produced in a polyclinic. On the eve before the operation, the patient should perform cleansing of the large intestine with an enema, and in the evening it is not recommended to eat food that leads to increased gas production-black bread, milk,

Lithotripsy is a non-invasive surgical procedure used to treat kidney stones. High-energy shock waves are transmitted from outside the body to break up kidney stones. The remaining kidney stone fragments are small enough that they can more easily pass through the urinary tract. Because lithotripsy is noninvasive and highly effective, it is one

Artificial and natural stones of various compositions and 5–15 mm in diameter were treated with BWL ™ in a water bath with ultrasound frequencies of 170, 285, and 800 kHz. All natural and artificial stones were fragmented in 36 seconds (for the softest, uric acid, stones) to 14.7 min (for the hardest, cystine, stones).
