All other prescription medications
Continue unless directed otherwise. Take approved medications on the morning of surgery with a small sip of water.
Fasting Instructions
Nothing to eat or drink for 8 hours before your arrival time
This includes no gum chewing or hard candy. Follow this rule strictly — eating or drinking before surgery may require postponing your procedure.
Blood thinners: do not stop without contacting your prescribing provider
If you have been prescribed aspirin or blood thinners by a cardiologist or other physician, contact that provider before making any changes. Do not stop on your own. Examples include: Warfarin (Coumadin), Plavix, Lovenox, Xarelto, Eliquis, and over-the-counter aspirin. If your blood thinner cannot be stopped for the required timeframe, contact your surgeon to discuss.

About the Procedure
What Happens During Surgery
How the procedure works
Once you are asleep under general anesthesia, a small flexible scope is passed through the urethra and bladder into the ureter — the tube that carries urine from the kidney to the bladder. The scope is advanced until the stone is located. A laser is used through the scope to break the stone into small fragments.
Stent placement
A stent (a small flexible tube) will likely be placed to allow stone fragments to pass in the urine. A stent may also be placed if swelling, inflammation, or narrowing is found in the ureter. In approximately 5% of cases the stone cannot be accessed due to a narrow ureter — in that case a stent is placed and a second surgery is scheduled to treat the stone.
Recovery
What to Expect After Surgery
Urinary burning
A burning sensation when urinating is common and temporary.
Blood in urine
Small amounts of blood in the urine are expected. This should improve within a few days.
Urinary frequency
You may feel the need to urinate more frequently than normal.
Stent discomfort
If a stent was placed, mild back or flank discomfort when urinating is common. Your stent removal appointment will be scheduled before discharge.
After Surgery
When to Call Your Doctor
Contact your care team if you experience any of the following after discharge:
Fever
Temperature over 101°F
Wound concerns
Redness, warmth, swelling, or drainage from the incision or surgical site
Breathing / chest
Shortness of breath or chest pain
After hours
Call (865) 305-9254 and follow prompts for the on-call provider. For emergencies, go to your nearest ER or call 911.
