Cálculos renales

Kidney calculi, also known as renal calculi, are hard deposits of minerals and salts that form inside the kidneys. They are usually small, but can grow to be quite large. Kidney calculi can cause pain and block the flow of urine, leading to other health problems.

What Causes Kidney Calculi?

Kidney calculi are caused by an imbalance of minerals and salts in the urine. This can be due to dehydration, certain medications, or a diet high in certain minerals. Other factors that can increase the risk of kidney calculi include obesity, family history, and certain medical conditions.

Diagnosis and Prevention of Kidney Calculi

Kidney calculi can be diagnosed through imaging tests such as an ultrasound or CT scan. Treatment may involve medications to help dissolve the calculi, or surgery to remove them. To prevent kidney calculi, it is important to drink plenty of fluids, maintain a healthy weight, and avoid certain medications.

Common Symptoms of Kidney Stones

• Severe pain in the side and back, below the ribs
• Pain that radiates to the lower abdomen and groin
• Pain that comes in waves and fluctuates in intensity
• Pain on urination
• Pink, red, or brown urine
• Cloudy or foul-smelling urine
• Nausea and vomiting
• Persistent need to urinate
• Urinating small amounts

When to See a Doctor

If you experience any of the symptoms of kidney stones, it is important to see a doctor right away. The sooner you get treatment, the less likely you are to experience complications. Your doctor can diagnose kidney stones with a physical exam, imaging tests, and a urine test.

Dehydration

One of the most common causes of kidney stones is dehydration. When your body does not have enough fluids, the urine becomes more concentrated and can form crystals that can eventually turn into stones. It is important to drink plenty of water throughout the day to help prevent kidney stones.

Diet

Certain dietary habits can also increase your risk of developing kidney stones. Eating a diet high in animal proteins, sodium, and sugar can increase the amount of calcium and other minerals in the urine, which can lead to the formation of stones. Eating a balanced diet with plenty of fruits and vegetables can help reduce your risk.

Family History

Having a family history of kidney stones can also increase your risk. If someone in your family has had kidney stones, you may be more likely to develop them as well.

Medical Conditions

Certain medical conditions can also increase your risk of developing kidney stones. These include urinary tract infections, gout, and certain metabolic disorders. If you have any of these conditions, it is important to talk to your doctor about ways to reduce your risk.

Imaging Tests

Imaging tests are the most common way to diagnose kidney stones. These tests use X-rays, ultrasound, or computed tomography (CT) scans to create images of the kidneys and urinary tract. These images can help doctors identify the size, shape, and location of the stones, as well as any blockages or other abnormalities.

Urine Tests

Urine tests can help diagnose kidney stones by looking for substances that are commonly found in stones, such as calcium, oxalate, and uric acid. Urine tests can also detect infection, which can be a complication of kidney stones.

Blood Tests

Blood tests can help diagnose kidney stones by looking for substances that are commonly found in stones, such as calcium, oxalate, and uric acid. Blood tests can also detect infection, which can be a complication of kidney stones.

Other Tests

Other tests that may be used to diagnose kidney stones include a urine culture, a urine cytology, and a urine electrolyte test. These tests can help doctors determine the cause of the stones and the best course of treatment.

Conclusion

Kidney stones can be difficult to diagnose, but there are a number of tests and procedures that can help. Imaging tests, urine tests, blood tests, and other tests can all help diagnose kidney stones and determine the best course of treatment.

Symptoms

Discuss any symptoms you are experiencing with your doctor. Common symptoms of kidney stones include pain in the side or lower back, nausea, vomiting, and blood in the urine. Your doctor may also ask about any other medical conditions you have, as some conditions can increase your risk of developing kidney stones.

Diagnosis

Your doctor may recommend certain tests to diagnose your kidney stones. These tests may include a urine test, an ultrasound, or a CT scan. Your doctor may also order a blood test to check for any underlying medical conditions that may be causing your kidney stones.

Treatment

Your doctor will discuss the best treatment option for your kidney stones. Treatment options may include medications, surgery, or a combination of both. Your doctor may also recommend lifestyle changes, such as drinking more water and avoiding certain foods, to help prevent future kidney stones.

Questions

Be sure to ask your doctor any questions you may have about your condition. Your doctor can provide you with more information about your diagnosis, treatment options, and follow-up care.

Medication

Medication is often the first line of treatment for renal calculi. Medications such as alpha-blockers, calcium channel blockers, and diuretics can help to relax the muscles in the ureter, allowing the stones to pass more easily. In some cases, medications can also help to dissolve the stones.

Extracorporeal Shock Wave Lithotripsy (ESWL)

ESWL is a non-invasive procedure that uses shock waves to break up the stones into smaller pieces. The smaller pieces can then be passed more easily. This procedure is usually done under general anesthesia and can take up to an hour.

Ureteroscopy

Ureteroscopy is a procedure in which a thin, flexible tube is inserted into the ureter to locate and remove the stones. This procedure is usually done under general anesthesia and can take up to an hour.

Percutaneous Nephrolithotomy

Percutaneous nephrolithotomy is a surgical procedure in which a small incision is made in the back to access the kidney and remove the stones. This procedure is usually done under general anesthesia and can take up to two hours.

Laser Lithotripsy

Laser lithotripsy is a procedure in which a laser is used to break up the stones into smaller pieces. The smaller pieces can then be passed more easily. This procedure is usually done under general anesthesia and can take up to an hour.

Prevention

The best way to prevent renal calculi is to drink plenty of fluids, maintain a healthy diet, and avoid certain medications that can increase the risk of developing stones. It is also important to see a doctor if you experience any symptoms of renal calculi, such as pain in the side or back, nausea, or blood in the urine.

What Causes Kidney Stones?

Kidney stones are caused by a variety of factors, including dehydration, certain medications, and certain medical conditions. Dehydration occurs when you don't drink enough fluids, which can cause minerals and salts to become concentrated in your urine and form stones. Certain medications, such as diuretics and calcium-based antacids, can also increase your risk of developing kidney stones. Certain medical conditions, such as gout, urinary tract infections, and inflammatory bowel disease, can also increase your risk.

How Are Kidney Stones Treated?

Treatment for kidney stones depends on the size and type of stone. Small stones may pass on their own, while larger stones may require medications or surgery. Medications, such as alpha-blockers, can help relax the muscles in your ureter, allowing the stone to pass more easily. Surgery may be necessary to remove larger stones. In some cases, shock wave lithotripsy may be used to break up the stones into smaller pieces that can be passed more easily.
