Ureteroscopy with laser lithotripsy is a minimally invasive procedure that uses a thin scope and a laser to break up kidney and ureteral stones from the inside, with no cuts on your skin. Most people go home the same day.
Kidney or ureteral stones that are too large to pass on their own, are blocking the flow of urine, or keep causing pain or infection.
Bleeding, infection and temporary stent discomfort; rarely, injury or later narrowing of the ureter. Risks are minimised by treating any urine infection first, careful patient selection and an experienced urology team.
Urine test for infection, CT or other imaging of the stone, a review of your medicines (especially blood thinners), anesthesia consultation, and fasting per your hospital's protocol.
Stent removal a few days to about 2 weeks after the procedure, a check-up (often with imaging) to confirm the stone has cleared, and advice on preventing new stones.
The name describes two steps done in one session. First, ureteroscopy: your urologist guides a narrow, telescope-like instrument β rigid or flexible β through your urethra and bladder up into the ureter or kidney, using a small camera to find the stone directly. Second, laser lithotripsy: a thin laser fiber is passed through the scope to the stone. Most urologists now use a holmium laser, which delivers short, precise pulses of energy that fragment or „dust” the stone without damaging the surrounding tissue.
This combined approach is one of the standard options in current urology guidelinesΒ for stones that are too large to pass on their own or that are causing a blockage.
A small stone often passes by itself. A stone that is larger, stuck, or causing trouble usually announces itself, and these are the signs people most often notice:
None of these proves you need a procedure. They are simply the reasons a urologist may look for a stone and, if it isnβt passing, suggest removing it.

If some of these symptoms sound familiar, take a breath: stones are common and very treatable. A simple urine test, a blood test and a scan are usually enough to show whether a stone is there, how big it is and whether it needs treatment. Many stones pass on their own, and for the ones that don’t, this procedure is routine and usually done as a day case. If the pain is severe, you have a fever, or you can’t pass urine, get medical help the same day. Otherwise, you can talk it through with a urologist at your own pace. Ready to take the next step?

Before you arrive
Your care team typically includes a urologist, an anaesthetist or nurse anaesthetist, nursing staff, and a scrub technician.
During the procedure
The main advantage of this treatment is that it reaches the stone through your body’s natural passages, so recovery is usually gentler than with surgery that involves a cut. The benefits people notice most:
In short, you get a precise, minimally invasive way to remove the stone and a clear picture of what to do next.
The treatment has risks and trade-offs to discuss with your care team. The information below comes from this treatmentβs data and trusted clinical sources.
Bleeding, infection and stent discomfort are the most common. Risks are minimised by treating any urine infection beforehand, careful patient selection and an experienced urology team.
Common side effects after the procedure are usually mild and settle within days:
Who it may not suit: Very large or complex stone loads may be better treated another way, such as percutaneous nephrolithotomy (PCNL). An untreated urine infection or blood-thinning medicines need to be dealt with first, and your team will plan around them. These are general cautions, not a personal verdict. A qualified clinician must assess your full medical picture before recommending or delaying treatment.

During. You’re asleep (or numb from the waist down) and feel nothing. The scope reaches the stone, the laser breaks it up, and the fragments are removed or left to pass. The procedure itself usually takes 1 to 2 hours, and a temporary stent is placed at the end in most cases.
Right after. You’ll be monitored in a recovery area for an hour or two as the anaesthesia wears off. Because this is an outpatient procedure, you go home the same day in the vast majority of cases β you won’t stay overnight unless your urologist has a specific reason to keep you in. Plan for about 4 hours at the hospital or surgery center in total. For the day-by-day picture once you’re home, see Recovery below.
Serious problems are uncommon, but it helps to know what your team watches for. Most can be treated if they’re spotted early, which is why you’ll be told exactly when to call.
This is general information, not a personal risk assessment. Your urologist can tell you which of these apply to your stone and health history.
New or severe symptoms require prompt medical advice. Do not wait for a routine appointment if you feel seriously unwell.
Most people feel back to normal within a few days of the stent coming out. Until then, recovery is mostly about managing stent symptoms and drinking plenty of water.
First 24β48 hours. Mild burning when you pee, pink or red-tinged urine, cramping and a frequent or urgent need to urinate are common. They usually settle within a day or two. Pain relief, fluids and warmth (a heating pad or warm compress) help.
While the stent is in. Expect more discomfort and tiredness than the first day alone would suggest; this is normal and temporary. Your urologist will tell you when the stent comes out, typically a few days to about two weeks after the procedure, either with a removal string or in a short visit.
The following weeks. It can take 8 weeks or longer for all stone dust and fragments to clear, so keep drinking water. A follow-up visit, sometimes with imaging, confirms the stone is gone, and if your stone was analysed your urologist will explain what it means for preventing new ones.

Not quite. Ureteroscopy is the scope-based procedure that reaches the stone; lithotripsy is the general term for breaking a stone apart. Here the scope gets your urologist to the stone and the laser breaks it up.
ESWL breaks stones from outside the body with focused sound waves and no scope. Ureteroscopy reaches the stone directly, so it can treat stones ESWL can't break well and confirm the stone is gone in the same session.
No. You're under general or spinal anesthesia, so you're either asleep or numb from the waist down and won't feel it.
Usually, yes. A temporary stent keeps the ureter open while it heals and is removed a few days to about 2 weeks later. Your urologist decides based on your stone and how the ureter looks.
Most people return to normal activities a few days after the stent comes out. Stone dust can keep clearing for 8 weeks or longer, so keep drinking water.
Yes, stones can recur. Analysing a stone fragment, drinking enough fluid and following your urologist's diet or medicine advice can lower the chance of new ones.
