Ureteral stents help keep the ureter open, allowing urine to flow smoothly from the kidney to the bladder. They are commonly used to treat ureteral blockages caused by kidney stones, tumors, or other conditions. In most cases, these stents are temporary and need to be removed after a certain period. (1)

In this article, we’ll explore how ureteral stents are removed, what to expect during the procedure, and the essential steps for preparation and recovery.

How Is a Ureteral Stent Removed?

A ureteral stent is removed once the blockage or swelling in the ureter has resolved. This can be done in two ways: (2)

1- Removal Using a Cystoscope (Bladder Scope)

The most common method for stent removal is with a cystoscope, a quick and simple procedure where a small, flexible scope is inserted through the urethra to reach and remove the stent. The entire process typically takes 2-3 minutes.

• Before the procedure, a numbing gel is applied to the urethra to minimize discomfort.
• No general anesthesia is required, so you can eat and drink normally before and after the procedure.
• The procedure is safe and straightforward, meaning you can attend the appointment alone without needing a companion.

Preparation for Stent Removal with a Cystoscope (an hour before):

Your doctor may advise you to:
- Drink 3-4 cups of water.
- Take prescribed pain relievers and medications to relax the ureter before the procedure as per his instructions.

2- Self-Removal Using an Attached String

In some cases, the stent comes with a small string extending from the urethra, allowing you to remove it yourself at home. However, this should only be done following your doctor’s instructions. Your doctor will inform you of the right time to remove it and provide clear guidelines for a safe and smooth removal.

Preparation for Self-Removal (one hour before):

Your doctor may recommend:

• Drinking 3-4 cups of water.
• Taking pain relievers and other medications to relax the ureter as recommended by your doctor, just like in the cystoscope procedure.

How to Remove the Stent at Home:

• It’s best to remove the stent in the morning.
• You can do this while showering or sitting in a bathtub.
• Gently and steadily pull the string until the stent is fully removed.
• After removal, examine the stent to ensure it is intact and undamaged.

What If the Stent Doesn’t Come Out?

In rare cases, the string may break, or the stent may not come out easily. If this happens, do not force it. Instead, contact your doctor immediately, as they can safely remove it using a cystoscope.

When Is a Ureteral Stent Removed?

In most cases, a ureteral stent is temporary and is removed once the ureter blockage has resolved. This usually happens within a few days to several weeks after placement.

In rare cases, some patients may need to keep the stent for a longer period, sometimes for several months or even years. In such situations, the doctor will typically replace the stent every 3 to 6 months to prevent complications like urinary tract infections (UTIs) or kidney stone formation. (3)

Possible Side Effects After Stent Removal

After the stent is removed, you may experience some mild and temporary side effects, including: (4)

• Pain or discomfort
• Blood in the urine
• Increased urge to urinate
• Burning sensation while urinating

Recovery and Recommendations: After Removal

Recovery after ureteral stent removal typically takes a few days, during which you may experience mild discomfort or side effects that gradually improve over time. To promote a smooth recovery, consider following these essential tips: (2)(4)

• Drink 2 to 3 liters of water daily to flush out the urinary tract and help prevent infections.
• Take pain relievers – Use any pain medications or other prescribed drugs as recommended by your doctor to ease discomfort.
• A warm bath can help relax the ureter and relieve cramps.
• Your doctor may suggest a mild laxative for the first few days to prevent constipation
• Incorporate fruits, vegetables, and juices into your diet to support digestion.
• Stick to scheduled check-ups to ensure proper healing.

When Should You See Your Doctor?

It’s normal to feel some discomfort after your ureteral stent removal, but if you notice any of the following, it’s important to reach out to your doctor: (4)

• Pain in your kidney area
• Fever above 38.6°C 
• Body aches and chills
• Cloudy or unusually murky urine

These could be signs of a urinary tract infection (UTI) that might need IV antibiotics.
