What are the best treatments for kidney stones?

Treatments for kidney stones depend on the size, location, and composition of the stone, ranging from conservative "watchful waiting" and hydration to minimally invasive surgical interventions. For many patients, the primary approach involves managing pain while facilitating the natural passage of small kidney stones, while larger or obstructive stones require professional urological procedures.

What are the first-line treatments for kidney stones?

For small kidney stones that do not cause severe obstruction or infection, the initial strategy is often "medical expulsive therapy." This involves high fluid intake to flush the urinary system and the use of specific medications to relax the ureter. If a patient experiences intractable pain, fever, or signs of kidney damage, immediate intervention by a urologist is required to bypass or remove the stone.

What medications are commonly used?

Physicians may prescribe several classes of medication to assist in the management of kidney stones:

• Alpha-blockers (e.g., tamsulosin): These help relax the smooth muscles of the ureter, potentially making it easier to pass a kidney stone.


• Analgesics: Non-steroidal anti-inflammatory drugs (NSAIDs) or other pain relievers are used to manage the intense renal colic associated with kidney stones.


• Citrate supplements (e.g., potassium citrate): Prescribed for patients with recurrent calcium stones to alter urine chemistry and prevent new crystal formation.

When is surgery required for kidney stones?

When kidney stones are too large to pass spontaneously or cause complications, surgical options include:

• Shock Wave Lithotripsy (SWL): Using sound waves to break the stone into smaller fragments.


• Ureteroscopy: A thin scope is inserted through the urethra to locate and remove or fragment the stone.


• Percutaneous Nephrolithotomy (PCNL): A procedure used for very large kidney stones where a small incision is made in the back to access the kidney directly.

Which specialists should be on the care team?

Effective management of recurring kidney stones requires a multidisciplinary team. Your care should be led by a urologist, who specializes in the urinary system. Depending on the stone composition, a nephrologist or a metabolic dietitian may also be involved to identify underlying metabolic imbalances that contribute to stone formation.
