Kidney stones
Kidney stone symptoms
The symptoms of kidney stones depend on the size and shape of the stone, as well as its location in the kidney, whether there are infections, obstructions, and other factors. Smaller kidney stones, which are smooth, can be expelled with the urine without causing noticeable symptoms. Stones lodged in the lower part of the renal pelvis or in the calyces can be asymptomatic. If the kidney stones are larger, located in the calyces or the renal pelvis, they can compress the kidney and cause back pain or dull pain because the stones can lead to the dilation or obstruction of the renal pelvis or kidney. Patients may experience back pain, fever, and if there is an infection, localized fever may occur. Additionally, kidney stones can scratch the mucous membrane of the ureter or kidney, causing bleeding.
What department should I go to for kidney stones?
Kidney stones are a urological condition requiring treatment at a hospital's urology department. Diagnosis involves imaging, such as ultrasound or CT scans, to determine the stone's exact size and location for appropriate treatment. If the stone is relatively small, with a diameter of six millimeters or less, referred to as a small stone, it generally does not require special treatment. Increased fluid intake, frequent urination, and exercise can help facilitate the expulsion of the stone. If the stone's diameter is between 0.7 and 1.5 centimeters, extracorporeal shock wave lithotripsy or ureteroscopy may be considered. For larger stones exceeding 1.5 centimeters, possibly accompanied by hydronephrosis, the recommended treatments are percutaneous nephrolithotomy 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.
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.
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.
Can kidney stones recur?
Kidney stones are recurrent because their formation is related to daily water intake, diet, genetics, lifestyle habits, and certain diseases. Therefore, even if the stones are treated surgically or expelled from the body through conservative means, recurrence can occur if dietary and lifestyle habits are not monitored or if the primary disease is not controlled. It is important to drink plenty of water, urinate frequently, and dilute the urine to reduce the recurrence of stones. If there are specific diseases present, such as hyperuricemia or hyperparathyroidism, active treatment is necessary.
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.
Is urethral calculus the same as kidney stones?
Urethral calculi and kidney stones are not the same concept. Urethral calculi refer to stones located in the urethra, while kidney stones are stones located within the kidney. The cause of urethral calculi is usually due to stones from the kidney or ureter becoming lodged in the urethra, which clinically often results in symptoms such as frequent urination, urgent urination, and difficulty urinating. Severe cases may lead to urinary retention. If kidney stones are small and smooth, they may not cause any symptoms. However, larger kidney stones can cause localized back pain, and if infected, may also lead to high fever. The treatment methods for kidney stones and urethral calculi are also different. Urethral calculi can generally be removed through surgery or endoscopic methods, while the treatment for kidney stones depends on the size and location of the stones.
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.
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.
