Urinary stones are a common condition of the urinary system. Stones can be found in any part of the kidney, bladder, ureter and urethra, but kidney and ureteral stones are the most common. Anyone who has suffered from stones knows that stone attacks are painful and therefore, once they occur, patients always want to kick the annoying little stone out of their bodies at the first opportunity. However, experts warn that extracorporeal lithotripsy has strict contraindications and is not as simple as one might think. The full name of what people often call extracorporeal lithotripsy should be extracorporeal shock wave lithotripsy. The patient is lying down on a huge lithotripter, and the extracorporeal shock wave is focused on the stone, causing the molecules of the stone to vibrate violently and the stone to disintegrate, thus breaking the stone in the body. After the stones are broken into small particles or even powder, they are discharged from the body through the urethra with urine. Because no surgery is required, many patients with stones always think of this “simple” treatment first. However, extracorporeal shock wave lithotripsy is not simple, and the consequences of blind lithotripsy are very serious. In the minds of many stone patients, extracorporeal lithotripsy is like a “panacea”, where there is a stone to hit, a hit is accurate. In order to be successful, the stone should be monitored in real time under X-ray or B-ultrasound positioning. The health authorities are now promoting the standardization of training and qualification of medical personnel. In some “small hospitals” that are contracted to carry out the treatment through “package lithotripsy” advertising, the risk of treatment is greater. In fact, usually the smaller stones, the diameter of 0.5 cm or less, the patient has no obvious symptoms, hydronephrosis is not serious, you can take lithotripsy drugs, drinking water, the stones may have their own discharge, this case does not need extracorporeal lithotripsy; and the diameter of more than 0.5 cm, less than 2 cm urinary stones, usually through the extracorporeal lithotripsy technology, the stones will be broken and discharged; more than 2 cm Even if the stones are shattered, they will still not be discharged because of the large size of the stones, which is equivalent to useless work. The second, blind lithotripsy, the harm is not small Now many small clinics promote “thousands of dollars of stone package shattering”, “disposable lithotripsy”, etc., some patients want to cheap, or lack of understanding, gullible believe in these propaganda, the results suffered a lot of pain. The first success rate of extracorporeal shock wave lithotripsy for urinary stones is about 50% to 70%. The success rate depends on the size, hardness and nature of the stone. Some small hospitals repeatedly perform extracorporeal lithotripsy many times in order to seek greater benefits, which makes the kidneys of patients suffer a lot. Usually the interval between extracorporeal lithotripsy for kidney stones is about 3 weeks and for ureteral stones is about 2 weeks. Usually after 2 times of extracorporeal lithotripsy in the same area, if the stone does not respond at all, the method should be shelved. If the stone is small and the hydronephrosis is not heavy, you can wait for observation, and then take appropriate treatment when it grows up or becomes symptomatic; or then other treatment options should be considered under the guidance of a specialist extracorporeal lithotripsy should be based on the principle of maximum protection of the kidney. If the interval between extracorporeal lithotripsy is too short, too many times will cause damage to human tissues, small blood vessels in the kidney will rupture and bleed, serious acute renal hemorrhage, acute renal failure, kidney rupture and eventually lead to nephrectomy of Mr. Zheng occurred from time to time. In addition, because most lithotripsy triggers the atrophy of the kidney, chronic renal insufficiency, also caused urologists to pay great attention to. Shen Jihong especially pointed out that in the process of extracorporeal lithotripsy, the health care provider needs to monitor the energy level and lithotripsy time all the time, as well as to observe the lithotripsy site and the movement of stones with ultrasound from time to time, so be sure to go to a regular hospital for extracorporeal lithotripsy. Ureteral stones will have 2~3 times of hematuria after extracorporeal lithotripsy, and kidney stones will have hematuria in 1~2 days, these are normal, drink more water and take more rest, after the stones are discharged, they should be sent to the hospital for stone analysis, which is helpful to prevent the recurrence of stones. Third, the method of “stone crushing” should be different from person to person. Patients who are not eligible for extracorporeal lithotripsy actually have a lot of treatment options now. With the development of technology, there are more and more minimally invasive techniques in addition to extracorporeal lithotripsy. For example, percutaneous nephrolithotomy is to establish a channel from the skin to the kidney at the waist, through which the nephrolithoscope is inserted into the kidney and the kidney stones are broken and removed directly by using laser, ultrasound and other lithotripsy tools; transurethral ureteroscopy is to use a fine mirror to insert into the ureter through the urethra and bladder to break and remove ureteral stones or kidney stones.
