Ureteroscopy
URS (Ureteroscopy) surgery is recommended if you have a large stone in your kidney or ureter. The surgery typically takes around 30 minutes and is often done as an outpatient procedure. Most patients can return to normal activities within two to three days.
Treatment Procedure
After you are under anesthesia, a telescope-like instrument called a ureteroscope is inserted through the urinary tract and into the bladder — without any surgical cuts or incisions. The scope is used to examine your urinary tract (kidneys, ureters, and bladder), locate the kidney stone, and either:
- Break it apart using laser energy
- Remove it using a basket-like device
To help manage swelling and allow proper urine drainage, a small plastic tube known as a ureteral stent may be inserted at the end of the procedure. This stent will be removed during a follow-up appointment.
Before Surgery
Please inform your care provider about the following:
- All prescription medicines, vitamins, supplements, herbs, and over-the-counter drugs you are taking
- Any known drug allergies, especially to contrast agents used in X-rays
- If you may be pregnant
You may be advised to:
- Undergo an EKG, X-rays, and blood/urine tests
- Discuss medications like aspirin, ibuprofen, warfarin, and NSAIDs with your doctor (some may need to be paused)
- Take prescribed antibiotics to prevent infection
- Confirm which medications you can take on the day of surgery — only with a small sip of water
- Avoid food or drink after midnight before surgery
- Arrange for someone to drive you home after the procedure
After Surgery
You may experience the following temporary side effects:
- Nausea or occasional vomiting
- Pain in the kidneys, lower back, abdomen, or sides (especially during urination)
- Blood in urine – color may vary from pink to reddish to brownish, but urine should remain translucent
- Urinary urgency and frequency
- Burning sensation during urination or movement
- Bladder spasms
If bleeding increases significantly, seek immediate medical attention or visit an emergency room.
Managing the Ureteral Stent
- The stent helps stone fragments pass and reduces risk of urinary blockage
- Some fragments may only pass after the stent is removed
- The stent is usually removed 4–7 days after surgery (or longer depending on individual recovery)
