If you’ve ever had a kidney stone, you know how quickly the focus shifts from “What is this?” to “How do I make it stop?”
Once a stone is diagnosed, the next step is choosing how to treat it. Many patients are surprised to learn there isn’t just one solution. Depending on your situation, your doctor may recommend one of three main approaches: letting the stone pass naturally, removing it with a minimally invasive procedure, or using non-invasive shockwave technology.
The right option depends on several factors, including the size and location of the stone, your symptoms, and your overall health. Here’s a straightforward look at how each approach works and when it may be considered.
Watchful Waiting (Observation)
For smaller stones, your doctor may recommend allowing the stone to pass on its own. This approach is often supported with pain management, hydration, and sometimes medication to help relax the ureter
Watchful waiting is typically considered when:
- The stone is small (often under 5 mm)
- Pain is manageable
- There are no signs of infection
- The stone is not blocking kidney function
What to expect: Passing a stone can take anywhere from a few days to several weeks. Your doctor may recommend drinking plenty of fluids and, in some cases, prescribe medications such as an alpha-blocker to help the stone move more easily.
Things to keep in mind: Even small stones can be painful, and there’s no exact timeline for when they will pass. If symptoms worsen or the stone does not pass, another treatment may be needed.
Ureteroscopy (URS)
Ureteroscopy is a minimally invasive procedure that allows a physician to directly access and treat the stone. A small scope is inserted into and passed through the urinary tract to locate the stone, which can then be removed or broken into smaller pieces using a laser.
Ureteroscopy is often used for:
- Stones that have not passed on their own
- Stones located in the lower ureter
- Stones that are unlikely to respond to shockwave treatment
What to expect: This procedure is typically performed under anesthesia. Patients can sometimes go home the same day. Noteworthy, though, is that in many cases, a temporary ureteral stent is placed to help with healing and urine flow. A second procedure is required to later remove the stent.
Things to keep in mind: Ureteroscopy often clears the stone in a single procedure. However, because it involves instruments entering the urinary tract, recovery may include temporary discomfort, especially if a stent is placed.
Extracorporeal Shockwave Lithotripsy (ESWL)
Lithotripsy is the only non-invasive kidney stone treatment option. It uses targeted shockwaves to break a kidney stone into smaller fragments, which can then pass naturally through the urinary system.
ESWL is commonly used for:
- Stones in the kidney or upper ureter
- Small- to medium-sized stones (typically under 2 cm)
- Stones that are likely to respond well based on their composition and density
What to expect: During the procedure, you lie on a treatment table while shockwaves are directed at the stone from outside the body. The treatment typically takes about 45–60 minutes, and patients go home the same day.
Over the following days or weeks, the broken fragments pass naturally.
Things to keep in mind: Lithotripsy does not require incisions or scopes, making it the only non-invasive treatment option for kidney stones. In some cases, more than one treatment may be needed, and passing fragments can cause mild, temporary discomfort.
A Quick Comparison
| Watchful Waiting | Ureteroscopy | Lithotripsy (ESWL) | |
|---|---|---|---|
| Invasiveness | None | Minimally invasive | Non-invasive |
| Anesthesia | None | Typically required | Sedation or anesthesia, depending on the case |
| Recovery | Varies | Several days to a week | Usually same day |
| Best for | Small stones | Lower ureter or complex stones | Kidney/upper ureter stones |
| Stone removal | Natural passage | Removed or fragmented | Fragmented, then passed |
So, Which Option Is Right for You?
There’s no one-size-fits-all answer.
Each treatment option has a role, and the best choice depends on your specific situation. Factors like stone size, location, composition, and your personal preferences all play an important part in the decision.
Ureteroscopy may be recommended when immediate removal is needed or when stones are unlikely to pass or break easily. Watchful waiting can be appropriate for smaller stones that are likely to pass on their own.
For many patients, however, lithotripsy offers an effective, lower-impact alternative to surgery when the stone is a good candidate. Because it is non-invasive and typically allows for a quicker return to normal activities, it’s absolutely worth discussing with your provider.
The Bottom Line
If you’ve been diagnosed with a kidney stone, you have options. The most important step is making sure you understand them.
Talk with your doctor about what approach makes the most sense for your specific case, and don’t hesitate to ask whether lithotripsy is a viable option for you.
When you’re informed, you’re in a better position to make the decision that’s right for your health, your comfort, and your lifestyle.
