Kidney Stones: Diagnosis & Prevention
We find the cause, prevent recurrences, and treat stones with the least hassle possible — from comprehensive metabolic testing and preventive medications to best-in-class surgical options when needed.

Comprehensive Metabolic Stone Evaluation
Most stones are preventable once we understand your unique risk factors. Our evaluation looks for the imbalances that drive stones — and then we fix them.
Blood Work
- Metabolic panel (kidney function, electrolytes)
- Calcium, uric acid (and others as indicated)
- Parathyroid testing when appropriate
48-Hour Urine Collection
- Volume, pH, citrate
- Calcium, oxalate, uric acid
- Sodium, creatinine, other stone promoters/inhibitors
What we do with the results: Create a targeted prevention plan. We can almost always prescribe a medication to reduce stones — most commonly potassium citrate, a potent inhibitor that raises urinary citrate and alkalinizes urine to prevent crystals from forming.
How We Diagnose Stones
Ultrasound (US)
- Radiation-free, quick, and office-friendly
- Great for screening and follow-up
Computed Tomography (CT)
- Highest accuracy for stone size and location
- Guides decisions on medical vs surgical management
Treatment Options (When You Have a Stone)
Medical Expulsive Therapy (MET)
- For stones <5 mm likely to pass on their own
- Prescription medication to relax the ureter and ease passage
- Pain control + hydration plan, close follow-up
ESWL (Shock Wave Lithotripsy)
- Non-invasive; no incisions
- Breaks stones into sand-like fragments to pass naturally
- Performed pain-free under general anesthesia in our ASC
URS + Thulium Laser & Stent
- Flexible ureteroscopy reaches the stone through natural passages
- Modern thulium laser precisely dusts the stone
- Temporary stent supports drainage and healing
- Done in our state-of-the-art Ambulatory Surgery Centers
Which Option Is Best?
- Depends on stone size, location, density, and your goals
- We tailor care to minimize pain, downtime, and recurrence
Common Causes of Kidney Stones
- Low fluid intake (concentrated urine)
- High sodium diet
- Low urinary citrate (a natural inhibitor)
- High oxalate or uric acid in urine
- Genetics and family history
- Metabolic conditions (e.g., gout, hyperparathyroidism)
- Certain medications or supplements
- Digestive diseases or bariatric surgery (malabsorption)
- Obesity and insulin resistance
Diet & Fluid Recommendations
Fluids
- Aim for urine output ≥ 2–2.5 liters/day (usually 2.5–3 L fluid intake)
- Spread fluids throughout the day; add a glass at bedtime
- Water first; consider citrus-infused water to boost citrate
Sodium
- Limit sodium to ~1,500–2,000 mg/day
- Avoid heavily processed/restaurant foods
Calcium & Oxalate
- Do not over-restrict calcium; get normal dietary calcium with meals
- Pair calcium foods with oxalate-rich foods to bind oxalate in the gut
- Moderate high-oxalate items (spinach, nuts, beets, rhubarb, dark chocolate)
Protein & Citrate
- Moderate animal protein; incorporate plant proteins
- Add citrate-rich foods (lemons, limes, oranges)
Medications That Help Prevent Stones
- Potassium citrate: boosts urinary citrate and raises pH — a potent stone inhibitor
- Other options may include thiazides or allopurinol, depending on your 48-hour urine profile
We personalize therapy to your stone type and metabolic results, with periodic monitoring to keep you stone-free.
