What Determines Kidney Stone Treatment?

Stone size is a key factor, but several other elements influence treatment decisions:

Stone Composition: Different types of stones (calcium oxalate, uric acid, struvite, etc.) respond differently to treatment.
Location: Where the stone is located within the urinary tract affects how easily it can pass or be removed.
Symptoms: The severity of your symptoms will guide treatment choices.
Overall Health: Your general health and any pre-existing conditions play a role in determining the safest and most effective treatment.

How Are Kidney Stones Diagnosed?

Your doctor will use various methods to diagnose kidney stones and determine their size:

Physical Examination: A physical exam helps assess your symptoms.
Urinalysis: This test checks for blood and crystals in your urine.
Imaging Tests: These include X-rays, CT scans, and ultrasounds to visualize the stones and determine their size, location, and number.

What Happens If a Kidney Stone Doesn't Pass?

Larger kidney stones (over 6mm) may not pass on their own and could cause complications such as:

Obstruction: Blockage of the urinary tract.
Infection: Bacteria can build up in the blocked area, leading to urinary tract infections (UTIs).
Kidney Damage: Prolonged blockage can damage the kidneys.

Preventing Kidney Stones

Lifestyle changes can help reduce your risk of developing kidney stones:

Drink Plenty of Fluids: Staying well-hydrated helps flush out minerals that can contribute to stone formation.
Maintain a Healthy Diet: Limit foods high in sodium, oxalate, and purines.
Manage Weight: Obesity increases the risk of kidney stones.
Regular Exercise: Physical activity promotes overall health.

When to Seek Medical Attention

Seek immediate medical attention if you experience:

Severe pain in your flank or side.
Blood in your urine.
Fever or chills.
Nausea or vomiting.
