Kidney stones larger than 6 mm often require medical intervention because they are less likely to pass on their own. Treatment depends on the size, location, symptoms, and overall health of the patient. Here are the common treatments for stones >6 mm:
1. Extracorporeal Shock Wave Lithotripsy (ESWL)
How it works: Uses sound waves to break the stone into smaller pieces that can pass more easily.
Best for: Stones located in the kidney or upper ureter, typically less than 2 cm in size.
Limitations: Not ideal for very hard stones, very large stones, or stones in the lower ureter.
2. Ureteroscopy with Laser Lithotripsy
How it works: A thin scope is passed through the urethra and bladder into the ureter or kidney. A laser is used to break the stone into pieces.
Best for: Stones in the ureter or kidney; works well for stones up to 2 cm or more.
Benefits: Minimally invasive and effective for a variety of stone sizes and types.
3. Percutaneous Nephrolithotomy (PCNL)
How it works: A small incision is made in the back, and a scope is inserted directly into the kidney to remove or break up the stone.
Best for: Very large stones (>2 cm), complex or multiple stones, or those resistant to other treatments.
Note: This is a more invasive procedure but very effective.

4. Medical Expulsive Therapy (only sometimes)
When used: Occasionally, if the stone is just over 6 mm and located in the ureter, medications like alpha-blockers (e.g., tamsulosin) may help relax the ureter to allow passage.
Monitoring: Regular imaging and symptom monitoring are essential to avoid complications like infection or kidney damage.
5. Supportive Measures
Pain control: NSAIDs or opioids if needed.
Hydration: Encouraged unless contraindicated.
Monitoring: Repeated imaging to assess stone movement.
Emergency Situations
Immediate treatment is needed if:
There is fever (suggesting infection).
Kidney function is compromised.
The pain is unmanageable.
There is complete obstruction.
