Kidney stones are masses of tiny crystals that form in the kidney or urinary tract. They can cause excruciating pain and may require a trip to the emergency room. Depending on the stone's size and location, it may pass on its own with proper hydration and pain management, or it might require medical intervention. If left untreated, kidney stones can enlarge, block the urinary tract, and cause infections, necessitating surgery or other procedures such as ureteroscopy or percutaneous nephrolithotomy. In some cases, a hospital stay is necessary for treatment and observation, especially if there are complications or the patient needs IV fluids.

Kidney stone symptoms: abdominal pain, fever, chills, nausea, vomiting, and sudden changes in urinary patterns
Kidney stones are small, hard clusters of crystals that form from substances in your urinary tract. They can cause extreme pain as they pass through your urinary tract and out of your body. The pain often gets worse in waves and can be felt in the lower back, belly, side, or groin. In men, pain may also be felt in the testicles.
Kidney stones can be as small as a grain of sand or as large as a pearl. Smaller stones may pass through the urinary tract without causing any noticeable symptoms. However, larger kidney stones can get trapped in the ureter, the tube that connects the kidney to the bladder, causing a blockage. This can lead to a build-up of waste products and bacteria, resulting in a kidney infection.
If you experience any of the following symptoms, it is important to seek medical attention as they may indicate a blockage or infection:
- Abdominal pain: Intense pain in the abdomen, side, or groin may indicate a blockage caused by a kidney stone. This pain can be excruciating and is often felt in waves.
- Fever and chills: A fever, coupled with chills, can suggest that the kidney stone is infected.
- Nausea and vomiting: These symptoms often accompany a kidney stone blockage or infection and require immediate medical attention.
- Sudden changes in urinary patterns: Difficulty urinating, reduced urine output, or blood in the urine can indicate a blockage or infection.
Depending on the size and location of the kidney stone, your healthcare provider may recommend different treatment options. Smaller stones that are not causing any symptoms may be monitored until they pass naturally. However, larger stones or those causing complications may require a procedure to break them up and remove them, such as shock wave lithotripsy (SWL), ureteroscopy (URS), or percutaneous nephrolithotomy (PCNL).

When to go to the hospital: when kidney stones are too big to pass naturally, causing a blockage
Kidney stones are masses of tiny crystals that form in the kidneys or urinary tract. They can be extremely painful to pass, even if symptoms are mild. While small kidney stones (less than 5 mm in diameter) usually pass on their own without medical intervention, larger kidney stones may require a trip to the hospital.
Kidney stones can cause a blockage in the urinary tract, or ureter, which is the tube that connects the kidney to the bladder. This can lead to a build-up of urine in the kidneys, which can cause severe pain and other symptoms such as nausea and vomiting. If left untreated, kidney stones can become infected, leading to additional health issues.
If you are experiencing any of the following symptoms, you should go to the hospital or seek medical attention:
- Excruciating abdominal or back pain that is not relieved by over-the-counter pain medication
- Fever, chills, or sudden changes in urinary patterns, such as difficulty urinating or an inability to urinate
- Nausea and vomiting
- Dehydration
If you are experiencing any of these symptoms, it is important to seek medical attention immediately. At the hospital, you may undergo imaging tests such as a CT scan to detect kidney stones and blockages. Treatment options may include surgery or shock wave lithotripsy (SWL) to break up the kidney stones into smaller pieces that can be passed in the urine.

Treatment options: surgery, shock wave lithotripsy, ureteroscopy, percutaneous nephrolithotomy, and medication
While most kidney stones pass without medical intervention, surgery may be the best treatment option in certain cases. Here are some treatment options for kidney stones:
Surgery
In rare cases, traditional or "open" surgery may be performed to treat kidney stones. However, this type of surgery is now rarely done due to the availability of less invasive techniques.
Shock Wave Lithotripsy (SWL)
SWL is a non-invasive procedure that uses high-energy shock waves to break up kidney stones into smaller fragments that can be passed out of the body through the urinary tract. This procedure does not require a hospital stay, and patients can usually go home the same day. SWL is typically performed as an outpatient procedure, and anesthesia is administered for the patient's comfort. Before the procedure, patients may need to undergo blood or urine tests and review their medications with their healthcare provider.
Ureteroscopy (URS)
URS is a surgical technique where a ureteroscope, a narrow, flexible instrument, is inserted through the urethral opening to reach the stone in the ureter or kidney. A small laser fiber is then passed through the ureteroscope to break up and remove the stone. This procedure does not require any incisions and is typically performed as an outpatient procedure, allowing patients to return home the same day and resume normal activities within 2 to 3 days.
Percutaneous Nephrolithotomy (PCNL)
PCNL is a surgical procedure used for larger kidney stones (greater than two centimeters) or stones in hard-to-reach locations. It involves making a small incision, usually in the patient's back, to create a narrow tunnel directly to the kidney. A nephroscope (surgical tool) is inserted through the incision to view, break up, and remove the stones. Patients undergoing PCNL typically require an overnight hospital stay and can expect a recovery period of about 1 to 2 weeks before returning to normal activities.
Medication
In addition to these procedures, medication may also be prescribed to treat kidney stones or manage related symptoms.

Prevention: staying hydrated, reducing salt intake, maintaining a healthy weight, and dietary changes
Kidney stones are crystallized minerals that form in the kidneys and can cause a lot of pain and discomfort. While smaller stones usually pass easily, larger ones may require medical intervention, such as surgery. In most cases, treating kidney stones involves increasing fluid intake, taking pain medication, and using medications that make the urine less acidic.
Staying hydrated
Staying properly hydrated is crucial for preventing kidney stones. Aim for at least eight 8-ounce cups of water per day. Water dilutes the substances in urine that lead to stone formation. Additionally, drinking water with fresh lemon juice or incorporating low-sugar/no-sugar lemonade and orange juice can increase citric acid levels, which help prevent and break up kidney stones.
Reducing salt intake
Decreasing salt and sodium consumption is another important strategy for kidney stone prevention. Salt can increase the concentration of certain substances in the urine, promoting stone formation. It is advisable to limit salty foods and monitor sodium levels in processed and packaged foods.
Maintaining a healthy weight
Maintaining a healthy weight is beneficial for preventing kidney stones. Being overweight or obese can increase the risk of stone formation. Consuming whole grains can contribute to weight management and overall health, thereby reducing the risk of kidney stones.
Dietary changes
Making dietary changes can significantly impact the prevention of kidney stones. Here are some specific dietary recommendations:
- Consume calcium-rich foods: Calcium helps reduce the risk of kidney stones. Dairy products, such as milk and yogurt, are excellent sources of calcium.
- Limit oxalate-rich foods: While oxalate is naturally found in many healthy foods, excessive intake can increase the risk of kidney stones. Examples of oxalate-rich foods include beets, spinach, chocolate, rhubarb, tea, and certain nuts. However, it is essential to note that simply cutting out oxalate may not be advisable, as consuming calcium-rich foods alongside oxalate-rich foods can help reduce the risk of stone formation by binding the chemicals together before they reach the kidneys.
- Increase plant-based protein: Incorporating more beans, chickpeas, lentils, and peas into your diet can be beneficial.
- Limit animal protein: Red meat, poultry, eggs, and seafood are high in protein, which can increase the risk of kidney stones.
- Reduce caffeine intake: Caffeine can cause dehydration, which contributes to stone formation. Limit coffee, tea, and other caffeinated beverages.
- Limit sugary drinks: Sodas and sugary drinks have been linked to the development of kidney stones.
- Include cruciferous vegetables: Vegetables like Brussels sprouts, broccoli, and kale are rich in potassium, which helps decrease calcium loss and prevents stone formation.

Diagnosis: blood tests, kidney function tests, imaging tests, and checking for crystals in urine
Kidney stones are small, hard clusters of crystals that form from substances in the urinary tract. They can be extremely painful as they move through the urinary tract, sometimes requiring medical intervention.
If you are experiencing symptoms of kidney stones, you should seek medical attention. A doctor will be able to recommend tests to help diagnose kidney stones and understand the condition of the stone.
Diagnosis:
Blood Tests
Blood tests are used to check the health of the kidneys and look for signs of kidney or blood infection.
Kidney Function Tests
Kidney function tests are used to assess how well the kidneys are functioning and to detect any abnormalities. These tests may include checking the levels of creatinine and blood urea nitrogen (BUN) in the blood, as well as evaluating the glomerular filtration rate (GFR), which measures the kidney's ability to filter waste and fluids.
Imaging Tests
Imaging tests are used to check for kidney stones in the urinary tract, including the kidneys, ureters, and bladder. There are two main types of imaging tests:
- CT Scan (Computed Tomography Scan): This test uses X-rays and computing algorithms to create detailed images of the body. It can help detect kidney stones and determine their size and location.
- Ultrasound: This test uses sound waves to create images of the internal organs. It is often used as the first imaging test to avoid exposing patients to radiation from a CT scan. If the ultrasound is unclear, a CT scan may be required as a second imaging test.
Checking for Crystals in Urine
A urinalysis test can be performed to check for the presence of crystals in the urine, which is a common indicator of kidney stones. The test results will show the amount and type of crystals present, which can help diagnose the condition and determine the next steps in treatment.
It is important to note that not all kidney stones require hospitalisation. Smaller stones can often pass through the urinary tract without any symptoms and may not require medical intervention. However, if you are experiencing symptoms such as excruciating abdominal pain, fever, chills, or sudden changes in urinary patterns, you should seek medical attention immediately.
