Ureteric Stent Insertion

A ureteric stent is a soft, flexible tube placed inside the ureter to help urine drain from the kidney to the bladder. It helps protect the kidney from pressure, infection, and long-term damage.

What is ureteric stent insertion?

Ureteric stent insertion is a procedure where a thin, flexible tube is placed inside the ureter (the tube between the kidney and the bladder) to keep it open. If it becomes blocked, even briefly, urine can build up in the kidney, increasing pressure and raising the risk of infection or lasting kidney injury.

A stent creates a temporary channel for urine to flow freely. It’s commonly used when:

  • there’s a blockage, such as from a kidney stone or a narrowing (stricture)

  • the ureter may become swollen after surgery near the urinary tract

  • an instrument has been passed into the urinary system during another procedure

  • the kidney needs protection while inflammation settles

Most stents remain in place for a few weeks to a few months, depending on the cause of the blockage and your recovery. In some cases, long-term stenting is needed when a chronic obstruction cannot be fixed.

At Welbeck, our urologists are highly experienced in inserting and removing ureteric stents using minimally invasive techniques, and use stents with the latest designs and coatings to minimise discomfort. Your care will take place in our dedicated Urology centre, where you’ll receive clear, personalised aftercare advice to help you feel comfortable and confident as you recover at home.

More information

A ureteric stent insertion is usually carried out under general anaesthesia, although you may have it under spinal anaesthetic, or sedation, depending on your overall health.

During the procedure, a thin telescope called a cystoscope is passed through the urethra (the tube you urinate through) and into the bladder. Once the opening of the ureter is found, your surgeon gently threads the stent up into the kidney through the cystoscope, so no incisions are needed.  An X-ray is used to check that the stent is in the correct position before the procedure is finished.

After the procedure, you’ll be able to recover from the anaesthetic in private, comfortable surroundings until you feel well enough to go home. If you’ve had a general anaesthetic you’ll need someone to collect you and you won’t be able to drive for 24 hours.

Before leaving you’ll be given advice on aftercare and how long the stent needs to stay in place.  This is usually a few weeks to a few months, although for some patents it may be a long-term option for kidney drainage. 

Your team will arrange a follow-up appointment to check on your recovery and plan when the stent can be safely removed.

A ureteric stent is generally safe, but some people may notice symptoms while it’s in place.

Common stent-related symptoms include:

  • discomfort or pain in the bladder, kidney area, groin, or genitals

  • mild stinging when passing urine

  • small amounts of blood in the urine

  • feeling the need to urinate more often or urgently

  • the sensation of not fully emptying the bladder

These symptoms often worsen after physical activity or after urinating, but usually settle once the stent is removed.

Possible, but less common, complications include:

  • stent infection

  • stent encrustation (mineral build-up on the stent)

  • stent blockage

  • stent migration (movement out of position)

Your consultant will give you personalised instructions if there's any preparation needed before your procedure.  

Preparation may include:

  • stopping food and drink for a set number of hours before the procedure

  • adjusting, or temporarily stopping any blood-thinning medication

  • having a urine test to rule out infection

  • arranging for someone to take you home if you have a general anaesthetic

Recovery from ureteric stent insertion is usually quick. Most people feel back to normal within a few days, although mild stent-related symptoms may continue until the stent is removed. It’s normal to feel some discomfort in the lower tummy, back, or bladder region, especially when passing urine. Drinking plenty of water can help ease these symptoms and keep the urine clear.

You may notice small amounts of blood in the urine for a few days, especially after activity. This is normal and improves with rest and hydration.

You should avoid heavy lifting, strenuous exercise or long periods of activity for a short time after the procedure, as these can worsen stent discomfort. Most people can return to work within a day or so, depending on their job and how they feel.

Your consultant will arrange follow-up care and explain how long the stent needs to stay in place based on your individual situation.

Stent removal is a quick, minor procedure that usually takes just a few minutes. It’s typically performed under local anaesthetic using a flexible cystoscope. In some cases, a thread is attached to the lower end of the stent and sits just outside the urethra so that your urologist can remove the stent by simply pulling the thread.

Frequently asked questions

Most people can return to work and drive within a day or so, depending on how comfortable they feel and the type of work they do. If you’re taking strong pain relief or still experiencing significant discomfort, it’s best to wait until you feel fully safe and confident before driving or resuming normal activities. Your consultant will be able to give you specific advice on what to expect.

Ureteric stents are around 24cm to 30cm in length and have a small curl at each end — one sitting inside the kidney and the other in the bladder. These curls act like anchors, helping keep the stent securely in place so it can drain the kidney properly.

Stent removal is a quick procedure, and most people can return to their normal activities later the same day. You may feel some mild stinging or notice that you need to pass urine more often for a short time, but this usually settles quickly. If you feel uncomfortable, it’s sensible to take things gently and build back up to your usual routine as you feel ready.

Most ureteric stents are made from soft, flexible, medical-grade plastics such as polyurethane or silicone. These materials are designed to be gentle on the urinary tract, reduce irritation, and stay comfortably in place while the kidney drains. Your urologist will choose the stent material best suited to your condition.
