When a Stone Will Pass

Stones under 5 mm often pass with fluids and medical expulsive therapy. Larger stones, obstruction with infection, uncontrolled pain or a single functioning kidney need intervention.

Treatment Options

Ureteroscopy with laser fragmentation, shockwave lithotripsy and percutaneous procedures for large renal stones are chosen by stone size, location and hardness on CT.

Preventing the Next One

Recurrence rates approach 50% within five years without prevention. Two and a half to three litres of fluid a day, moderating salt, normal dietary calcium with reduced oxalate load, and treating metabolic causes make the biggest difference.

Frequently Asked Questions

Does drinking beer clear stones?

No. It causes dehydration overall. Plain water spread through the day is what works.
