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.

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 can kidney stones be expelled from the body?

The method of expelling kidney stones from the body is related to the size of the stones. If the diameter of the kidney stone is less than 0.6 centimeters, it can generally pass smoothly through the ureter and urethra to the outside of the body. This can be facilitated by drinking plenty of water and performing physical activity to naturally expel the stones. If a stone gets stuck in a physiologically narrow part of the ureter during expulsion, conservative treatment methods can be used to dilate the ureter, allowing the stone to pass on its own. If the kidney stones are relatively large but do not cause obstruction within the kidney, they can be observed temporarily without treatment. If larger stones get stuck in the ureter or urethra and cannot be expelled on their own, surgery is generally required to remove the stones. After surgery, it is also important to drink plenty of water and urinate frequently.

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.

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.

What department should I go to for kidney stones?

Patients with kidney stones need to visit the urology department of their local hospital for standard examinations and treatments. Doctors will conduct an ultrasound and CT scan of the urinary system to determine the exact size of the stones. If the stones are relatively small, measuring less than 1.52 centimeters, they can be treated with extracorporeal shock wave lithotripsy. If the stones are larger, surgical treatment is necessary. Currently, the main method is a minimally invasive percutaneous nephrolithotomy with holmium laser lithotripsy. Patients generally need about 7-10 days post-operation before they can be discharged from the hospital.
