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.

How is kidney stone surgery performed?

How is kidney stone surgery performed? For kidney stone surgery, if the indications for surgical treatment are met, it is generally carried out in the following ways: The traditional method is open stone removal, which involves large traumas and high risks, adversely affecting the patient's postoperative recovery. Nowadays, there are some minimally invasive techniques, such as crushing the stones with a laser and then removing the stones through a corresponding tube, or directly removing the stones using a corresponding soft-endoscope. Therefore, the choice of surgery for kidney stones is generally based on related examinations to select an appropriate treatment method to alleviate the patient's condition.

How to treat polycystic kidney kidney stones

Patients with polycystic kidney disease who develop kidney stones should be treated the same as patients without polycystic kidney disease. It is encouraged for patients to drink more water. If the stones are symptomatic, treatments such as extracorporeal shock wave lithotripsy or percutaneous nephrolithotomy may be considered. The main principles of treatment include managing renal colic, promoting stone expulsion, dissolving stones, or surgical interventions, as well as preventing recurrence. During a renal colic episode, it is primarily recommended to administer antispasmodic analgesics. Commonly used medications include scopolamine butylbromide and atropine, or combinations of atropine with pethidine or morphine. Expulsion therapy mainly involves drinking plenty of water, proper physical activity, and the use of some antispasmodic drugs to help expel the stones. Surgical treatment is aimed at patients with anuria and post-renal acute renal failure, or in cases where the stone diameter is larger than one centimeter, or if the expulsion therapy is ineffective, especially if there are still episodes of renal colic. Systemic metabolic disorders are an important cause of kidney stone formation, thus even after stones are cleared, recurrence is possible. Therefore, to prevent recurrence, it is advisable to ensure a daily urine output of 2000 to 2500 milliliters, avoid drinking tea and coffee as much as possible, adjust dietary habits, and treat systemic metabolic abnormalities, such as hypercalcemia, hyperuricemia, and cystinuria, among others.

Can people with kidney stones eat pineapple?

Patients with kidney stones can eat pineapple, as well as seasonal vegetables and fruits, as these have no impact on kidney stones. However, patients should avoid spicy and stimulating foods, and refrain from drinking alcohol. Treatment plans for kidney stones should be based on their size. It is advisable to first visit a hospital for urinary system ultrasonography and CT scans to assess the size of the stones. Smaller kidney stones may be treated with extracorporeal shock wave lithotripsy, while larger stones may require surgical intervention.

What department should I go to for kidney stones?

Kidney stones fall under the category of urological diseases. If one suffers from kidney stones, it is necessary to visit a hospital and register at the urology department. Examinations such as color ultrasound and CT scans are required to precisely determine the stone's location and size, and to check if it is accompanied by spinal infection or other conditions for appropriate treatment. If the stone within the kidney is comparatively small, such as about 5 millimeters, conservative treatment to facilitate stone expulsion is generally adopted. This can be achieved through increased water intake and frequent urination, physical exercise, in conjunction with medications like stone-expelling granules and solutions to promote the expulsion of the stone from the body. If the stone is larger and causes renal accumulation of fluid or even infection, it is necessary to first control the infection before proceeding with surgical intervention.

How to check for kidney stones?

For kidney stone examination, it is necessary to conduct an ultrasonography of the urinary system. Patients can go to the urology department of their local hospital for a formal examination. The ultrasound of the urinary system primarily looks at the size of the kidney stones and whether there is any water accumulation in the kidneys. Based on the results of the examination, an appropriate treatment plan can be formulated. For example, smaller kidney stones can be treated with extracorporeal shock wave lithotripsy, while larger kidney stones may require minimally invasive surgery.
