About 1 in 10 people will get a kidney stone during their lifetime, according to Cleveland Clinic. Most stones pass on their own. When one doesn't, a urologist will usually offer shock wave lithotripsy or ureteroscopy, and sometimes a third option for large stones.

This guide compares ureteroscopy and lithotripsy side by side: how each works, which stones each suits, and what recovery looks like, so you can weigh the options with your urologist.

When a kidney stone needs a procedure

Small stones often pass without treatment. Cleveland Clinic estimates that about 90% of stones smaller than 6 mm pass on their own, compared with about 60% of larger ones.

Waiting is reasonable when the pain is tolerable, there are no signs of infection, and the kidney is working well. The Urology Care Foundation says this period can last up to six weeks, and a medicine such as tamsulosin can relax the ureter to help a stone pass.

A procedure such as ureteroscopy is usually considered when:

• the stone fails to pass
• the pain is too severe to wait
• the stone is affecting how well the kidney works
• the stone causes repeated urinary infections

The main methods for kidney stone removal

When people search for the "4 methods for kidney stone removal," they usually mean medication to help a stone pass plus three procedures. The NIDDK describes the three procedures:

• Shock wave lithotripsy breaks the stone from outside the body.
• Ureteroscopy reaches the stone with a thin scope passed through the urinary tract.
• Percutaneous nephrolithotomy (PCNL) removes the stone through a small cut in the back.

Most decisions come down to ureteroscopy vs lithotripsy. PCNL is mostly for large kidney stones.

Shock wave lithotripsy

In shock wave lithotripsy (SWL), the urologist uses X-ray or ultrasound to aim shock waves at the stone from outside your body. The waves break the stone into small pieces that you pass in your urine over the following days to weeks. The lithotripsy procedure usually takes about an hour, and you go home the same day.

StatPearls describes SWL as a first-line treatment for kidney and ureteral stones smaller than 2 cm, with stone-free rates approaching 75%. Cleveland Clinic notes that success rates vary widely, from 30% to 90%.

Several things make lithotripsy for kidney stones a weaker choice:

• pregnancy, which rules it out
• a bleeding disorder or blood thinners that can't be paused
• a body mass index over 30, which lowers the success rate
• stones larger than about 15 to 20 mm, or stones over 10 mm in the lower part of the kidney

Compared with ureteroscopy, SWL needs no scope inside the body, but it is more likely to need a second session.

Ureteroscopy with laser lithotripsy

In ureteroscopy, the urologist passes a very thin scope through the urethra and bladder, up the ureter and, if needed, into the kidney. There are no incisions. Once the stone is in view, the urologist can grab it with a tiny basket or use a laser to break it into fragments or dust. This laser lithotripsy is what most people mean by laser kidney stone removal.

You're asleep under general anesthesia, and ureteroscopy usually takes an hour or two. Most people go home the same day.

According to the StatPearls chapter on ureteroscopy, it suits stones in the middle or lower ureter of any size and kidney stones smaller than 20 mm. Cleveland Clinic puts its usual range at 5 to 20 mm. It's also considered safe during pregnancy, and it can often be done in people taking blood thinners.

The trade-off is a stent. Many patients go home with a soft tube in the ureter for a few days.

Ureteroscopy vs lithotripsy: how urologists choose

There's no single winner. StatPearls reports that ureteroscopy has higher initial success and fewer repeat treatments than SWL, while SWL has fewer complications: one comparison it cites found 0% with SWL and 3.2% with ureteroscopy.

Ureteroscopy tends to fit when:

• the stone is in the lower ureter
• you're pregnant or take blood thinners
• the stone is hard, or you have a larger body size
• you want the best chance of being stone-free in one treatment

Shock wave lithotripsy tends to fit when:

• the stone is under about 1.5 cm and isn't in the lower part of the kidney
• you'd rather avoid a scope and a stent
• you accept a higher chance of needing a second session

Ask your urologist which of these factors drives their recommendation. If two urologists disagree, our guide to getting a second opinion before surgery explains when one is worth it.

PCNL for large kidney stones

Percutaneous nephrolithotomy is usually reserved for stones that are too big for ureteroscopy or SWL. Cleveland Clinic says the best candidates for percutaneous nephrolithotomy have stones 2 cm or bigger, or irregular stones that are hard to pass.

The surgeon makes a half-inch incision in the back or side and removes the stone through a tube placed directly into the kidney. PCNL has a reported success rate of about 75% to 98%. Most people stay in the hospital for one night, and many return to work in about a week.

Recovery after kidney stone surgery

Recovery depends on the procedure:

• Lithotripsy recovery: most people return to usual routines within a few days, while passing fragments for days to weeks.
• Ureteroscopy recovery: normal activities in 2 to 3 days, per the Urology Care Foundation. A kidney stone stent usually comes out within 4 to 10 days, and StatPearls cites 5 to 7 days after an uncomplicated case.
• PCNL: normal activities in 1 to 2 weeks per the Urology Care Foundation, and full recovery in 2 to 4 weeks per Cleveland Clinic.

A stent can cause discomfort and tiredness until it comes out. For tips on getting ready, read how to prepare for surgery.

Talk to a urologist about your options

The right kidney stone procedure depends on where the stone is, how big and hard it is, and your own health. Bring your imaging report and a list of your medications, including blood thinners, and use our questions to ask your surgeon to compare ureteroscopy and lithotripsy. Our guide to how health insurance works helps with planning.
