There are many causes leading to the formation of kidney stones, related to daily water and food intake, lifestyle habits, living environment, genetics, and certain diseases. For example, patients with hyperuricemia and those with hyperfunctioning parathyroid glands are prone to the formation of kidney stones. Additionally, individuals who often stay in high-temperature environments and neglect to drink water frequently and urinate regularly, can easily experience concentrated urine, which also promotes the formation of kidney stones. Furthermore, people who consume large amounts of calcium and oxalate-rich foods over long periods are also commonly at risk of developing kidney stones.

Are urinary stones the same as kidney stones?

Urinary stones and kidney stones are not exactly the same. Urinary stones refer to stones in the urinary system, including kidney stones, ureter stones, bladder stones, and urethral stones. Therefore, kidney stones are just one type of stones in the urinary system, and urinary stones include kidney stones. If kidney stones occur, one should promptly visit the hospital's urology department for examinations such as ultrasound or CT scans. This facilitates understanding the specific size, location, number of stones, and whether there is accompanying hydronephrosis or infection, allowing for targeted treatment. If the stones are small, drinking plenty of water, urinating frequently, and exercising can help expel the stones from the body. If the stones are large, or there is hydronephrosis, it is advisable to consider surgery as soon as possible.

Do you need to be hospitalized for kidney stones?

Patients with kidney stones need to decide on a treatment plan based on the size of the stones, which determines whether hospitalization is necessary. For kidney stones smaller than 1.5 cm, extracorporeal shock wave lithotripsy can be utilized, allowing the patient to avoid hospitalization. After treatment, the patient can go home, where it is advised to engage in physical activity, drink plenty of water, and urinate frequently to facilitate the expulsion of the stones. A follow-up ultrasound of the urinary system should be conducted one week later at the hospital to monitor the status of the stone expulsion. If the stones are larger than 1.5 cm, surgical treatment is required, which necessitates hospitalization.

Which department should I go to for kidney stones?

After developing kidney stones, it is necessary to promptly visit the urology department of a hospital for examination and treatment. Diagnostic procedures such as ultrasound, CT scans, and imaging are required to determine the exact location and size of the stones. If the stone inside the kidney is small, around five millimeters, this can often be managed by increasing water intake, frequent urination, exercising, and using medications such as stone-expelling granules and effervescent agents to facilitate the expulsion of the stones from the body. If the stone is large and causes hydronephrosis of the kidney, surgery is recommended as soon as possible. If there is a concurrent infection, it is necessary to control the infection before proceeding with surgical treatment.

How to deal with kidney stones?

For the treatment of kidney stones, it is first necessary to determine the specific size and location of the stones, and whether there are conditions such as hydronephrosis or infection to guide the treatment approach. If the stones inside the kidney are relatively small, such as about five millimeters, conservative treatment is primarily used. This can involve drinking more water, urinating frequently, and exercising more. When necessary, oral medications like stone expulsion granules or solutions can be taken to help expel the stones from the body. If the stones are larger and accompanied by hydronephrosis or even infection, it is necessary to control the infection first and then proceed with surgical treatment. Common surgical methods include percutaneous nephrolithotomy, ureteroscopic lithotripsy, or open surgery for stone removal.

Is kidney stones serious?

Whether kidney stones are serious depends on the specific size and location of the stones, and whether there is accompanying kidney hydronephrosis or infection. If it is just a small stone inside the kidney, such as one with a diameter of about five millimeters, this situation is not serious. By drinking more water, urinating frequently, exercising more, and combining with medications like stone expulsion granules and stone expulsion solutions, the stones can generally be expelled from the body. If the stones are large and cause kidney hydronephrosis, or even lead to pyelonephritis or renal abscesses, this situation is more serious. It requires anti-inflammatory treatment and timely surgical intervention to remove the stones, relieve the obstruction of the urinary system, and protect kidney function.
