The new sound wave device will allow you to destroy kidney stones without surgery
The first 19 people experienced a new non-invasive method of getting rid of kidney stones by crushing them with sound waves. Explosive wave lithotripsy (VVL) technology has successfully coped with most of the stones, and this is good news for people with this common ailment. Up to 15% of people face kidney stones. Often small grains of sand come out by themselves, but many still need surgery to avoid severe kidney damage.
For many years, doctors have been using sound waves to crush kidney stones with extracorporeal shock wave lithotripsy —ESWL), a method of intense acoustic pulses requiring sedation or even anesthesia. BBL differs from EUVL in that it can be carried out outside the hospital by means of a portable device and without sedation. The BBL method consists of short cyclic ultrasonic pulses that crush stones into pieces of 2 mm in diameter or less.
To 19 patients with up to three large stones less than 12 mm, VVL was applied, for 10 minutes per stone. 90% of the volume of stones was destroyed, while 39% of the target stones were fragmented into parts less than 2 mm, 52% had incomplete fragmentation. Doctors say that most of the remaining grains of sand should come out on their own without additional intervention. At the same time, VVL gives only a small and controlled damage to external tissues.
The BBL method will still undergo additional research before it is widely used in clinics. It is necessary to deduce the optimal method of its application, and the ultimate goal will be to develop a treatment that can be quickly implemented at home when the disease manifests itself in patients for the first time.
