Understand Kidney Stones and Shockwave Lithotripsy

Clear, patient-friendly education to help you understand kidney stones, SWL treatment, preparation, recovery, and prevention.

Understanding Kidney Stones

Kidney Stone Basics

Kidney stones are hard mineral deposits that form inside your kidneys and can cause pain when they move through the urinary tract. Understanding what causes them — and how they affect your body — is the first step toward confident care.

About Shockwave Lithotripsy

What is SWL

SWL is a non-invasive treatment that uses focused sound waves to break kidney stones into smaller fragments, making them easier to pass naturally. It’s safe, effective, and often the first-line treatment.

Day of Procedure

Getting Ready

On the day of your treatment, you’ll check in, meet your care team, and go through the procedure in a relaxed, monitored setting. Here’s what your day will look like, from start to finish.

During SWL

During Procedure

During the procedure, sound waves are precisely targeted at your stone to fragment it. The process is typically quick and performed under mild sedation or anesthesia for your comfort.

Recovery After SWL

Aftercare Tips

Recovery is usually fast, with most patients returning to normal activities within a day or two. We’ll guide you on pain relief, hydration, and what symptoms are normal as you heal.

Stone Fragmentation and Passage​

Passing Stones

After SWL, your body naturally passes the broken stone pieces through urine. Learn what to expect during this process, including tips to ease discomfort and track your progress.

Risks & Complications

Possible Risks

Like any medical treatment, SWL has some potential risks — from blood in urine to rare complications. Knowing what’s normal (and what’s not) helps you stay safe and reassured.

Follow-Up & Prevention

Staying Stone-Free

Regular follow-up is essential to monitor stone clearance and prevent recurrence. We’ll also share proven lifestyle and dietary tips to help you stay stone-free for the future.
