Kidney Stone Treatment

Overview

Small stones often pass naturally with fluids and pain relief. Larger stones, or stones that cause blockage, infection or severe pain, may need a procedure. The best option depends on the size, number and position of the stones.

Treatment options

• Ureteroscopy: a thin telescope is passed through the urinary tract to break up or remove stones, often using a laser
• Shock wave lithotripsy: shock waves from outside the body break stones into small pieces that can pass in the urine
• Percutaneous nephrolithotomy (PCNL): large kidney stones are removed through a small cut in the back
• A temporary stent may be placed to help urine drain

Before the procedure

You will have urine tests, blood tests and imaging such as an ultrasound or CT scan. Any urine infection is treated first.

After the procedure

Recovery depends on the procedure, and some patients go home the same day. Mild pain and blood in the urine are common for a short time. Drinking plenty of fluids helps prevent new stones.

Risks

Possible risks include bleeding, infection, discomfort from a stent and, rarely, injury to the ureter or kidney.
