Tests that may be needed
- Urine test and blood tests, including kidney function
- Ultrasound of the abdomen
- Non-contrast CT scan (KUB), which shows the stone’s size and position

Frequently asked questions
Does every kidney stone need an operation?
No. Many small stones pass by themselves with fluids and medicines. A procedure is considered when a stone is large, does not pass, keeps causing pain or infection, or blocks the kidney.
Can kidney stones come back?
Yes, stones can return. Drinking enough water and following diet advice based on your stone type can lower that risk.
