Kidney stones have a 100% recurrence rate in the long term “Often people in their thirties and forties suffer more from kidney stones.” Experts said that generally people aged 20-50 are likely to suffer from kidney stones, relatively less before the age of 20, and if there are no kidney stones after the age of 50, it proves that the person’s body has good metabolic function and the chance of growing again will be reduced. For these people, routine health checkups are very important to detect early lesions in time, so that they can spend the least amount of money and suffer the least amount of pain to treat kidney stones. Experts recommend that people who do not have kidney stones have an annual checkup. In the case of patients who have had kidney stones and are now cured, they need to have a medical checkup every six months. “Because there are studies that show that the long-term recurrence rate of kidney stones is 100 percent with a period of 18 years.” Experts stressed that the current human knowledge of kidney stones is still very superficial, and the treatment is only to “remove the stone”, can not really eradicate the cause of kidney stones, so as long as the patient has had kidney stones this disease, the future will certainly recur. Some kidney stone patients, because the diameter of the stone is within 6mm, not blocking the ureter, can take more water, more exercise, plus take medicine to drain the stone method of conservative treatment. However, experts emphasize that patients with such conservative treatment need to have a physical examination every 3 months to observe whether there is any change in the location and size of the stones. Because the kidney is connected to the bladder by the ureter and there is about 25 cm of “roadway” between the two, a stone from the kidney can block anywhere in the ureter, causing ureteral obstruction, which in turn may cause hydronephrosis or even loss of function. Therefore, even if the stone can be successfully discharged from the kidney, it is important to monitor its course and location. ”In the case of uric acid stones and infected stones, the stones tend to grow quickly, which makes it even more important to have frequent medical checkups.” The expert said he remembered that there was once a female patient with kidney stones in her 20s, who had a lithotripsy in September last year, but had a medical checkup in January this year and found another very large growing stone, and by the time the lithotripsy was performed again, the kidney was stuffed with stones inside the upper and middle calyces. He said that this type of patients, even if the lithotripsy surgery clean stones, but also continue to check, patients with uric acid stones need to go to the hospital for three or four months to check, in order to understand the stone situation in time for treatment.
