Most people do not have the habit of regular medical checkups, and most of them will seek medical attention only when they feel unwell, but in many cases, the damage to the body organs may be irreversible by the time they seek medical attention, which is often encountered in nephrology clinics. Kidney stones, which seem to be a common disease to the public, can sometimes have serious consequences. Kidney stones are caused by the abnormal accumulation of crystalline substances (such as calcium, oxalic acid, uric acid, cystine, etc.) in the kidney, and are a common and frequent disease of the urinary system. 90% of kidney stones contain calcium, of which calcium oxalate stones are the most common. 40% to 75% of kidney stone patients have varying degrees of back pain, lumbar discomfort, or vague pain or dullness when physical There is vague or dull pain with increased activity. There are also many patients who usually have no obvious symptoms, or whose symptoms are mild and do not attract enough attention, but have already developed serious urinary tract obstruction and hydronephrosis when they come to the clinic; prolonged failure to lift urinary tract obstruction may lead to atrophy of the kidney and loss of kidney function. There are many factors that influence stone formation; age, gender, race, genetics, environmental factors, dietary habits, etc. It is known that there are 32 components of urinary stones, the most common component being calcium oxalate, other components of stones such as ammonium magnesium phosphate, uric acid, calcium phosphate, and cystamine. The treatment of kidney stones includes medication and surgery, etc. Generally, medication is still used for those below 5 mm. Sodium potassium hydrogen citrate granules (Youlert) is one of the treatment drugs. Oral administration of sodium potassium hydrogen citrate granules can regulate urinary pH and excretion of citrate root, which can increase the solubility of uric acid and cystine stones, and play a lithotripsy and lithotripsy effect. In addition the usual diet should be paid attention to. All patients with kidney stones, without other contraindications should drink more water, which can help the discharge of small stones and reduce the formation of stones, preferably keeping the daily urine volume above 2000ml. Adjust the diet according to the composition of the stones: patients with oxalate stones should avoid drinking strong tea and eating spinach, tomatoes, various nuts, etc. Patients with uric acid and cystine stones should avoid intake of high purine foods (such as animal offal, shellfish, beef and mutton, etc.). Regular medical check-ups can also help to detect stones early and intervene actively to deal with them at a relatively small stage to avoid serious consequences of taking them lightly.
