What are kidney stones

Kidney stones are large crystals formed by urine “rusting” in the urethra, and if they become loose in the kidney or block the urine flow, they can cause symptoms, such as blood in the eyes and severe back pain. According to a large survey of 9310 Chinese people, 600 people were diagnosed with kidney stones, of whom 288 were male and 312 were female, and the corrected prevalence of kidney stones among Chinese adults was 5.8%, including 6.5% among men and 5.1% among women, according to the 2010 Chinese census. Accordingly, it can be estimated that there are currently 61.2 million adults with kidney stones in China, of whom about 34.7 million are men and 26.5 million are women. Kidney stone is a disease that “doesn’t hurt you, but hurts and kills you”. In addition, kidney stones are very prone to recurrence, and those with recurrent kidney stones should be considered to have congenital abnormalities in the structure and physiological functions of the kidney (acid-base balance, sodium and calcium excretion, etc.), and may be a lifelong disease. Studies have shown that the recurrence rate of kidney stones in patients with stones is 11%, 20%, 31% and 39% at the second, fifth, tenth and fifteenth years, respectively. Because of the high recurrence rate, it is important to prevent stone formation to reduce the incidence of the disease and medical expenses. With early knowledge of prevention, many people can avoid the embarrassing situation of “pain that kills you”.
