Is extracorporeal shock wave lithotripsy safe

summary

Extracorporeal shock wave lithotripsy is a good way to treat stones. In general, doctors will recommend that patients can use this new treatment, but we still have some doubts. Let's talk about the safety of extracorporeal shock wave lithotripsy.

Is extracorporeal shock wave lithotripsy safe

First, the basic principle of shock wave generation (liquid electricity) is to form a high-temperature and high-pressure plasma zone with high energy density on the discharge channel through high voltage, large current and instantaneous discharge, which can quickly convert electric energy into heat energy, light energy, force energy and sound energy. During the discharge process, the discharge channel expands rapidly and forms a pressure pulse in the water medium, that is, shock wave.

Second: Generally speaking, all lithotripters are composed of the most basic two parts, that is, the shock wave source which can crush stones and the precise positioning system for stones. The shock wave source is the core of the lithotripter. The shock wave source can be divided into electro-hydraulic shock wave source and electromagnetic shock wave source.

Third: with the improvement of lithotriptor, especially the application of low-energy lithotriptor in clinic, the pain of shock wave entering the body has been greatly reduced, and the pain in the treatment of renal pelvis and bladder stones has been very slight. Now, except that children do not need general anesthesia, they do not need anesthesia. The patients who are very nervous before operation can be given intramuscular injection of 50 mg pethidine half an hour before operation to achieve satisfactory analgesic effect.

matters needing attention

In general, extracorporeal shock wave lithotripsy is a relatively safe treatment, so patients don't need to worry too much. As long as they cooperate with the doctor's treatment plan, take medicine on time, and do a good job in the follow-up recovery, they can recover quickly.
