Kidney stents, also known as ureteral stents, are small, flexible tubes inserted into the ureter to treat or prevent blockages that impede urine flow from the kidney to the bladder. They are commonly used to address kidney stones, strictures, or tumours causing obstructions. The placement of kidney stents is typically performed in hospitals or surgical centres, but what about their removal? Is it also done in hospitals, and what is the process like? The removal of kidney stents can be done in hospitals, but it can also be performed in a doctor's office or even at home under the guidance of a healthcare team. The method of removal depends on the type of stent and the patient's condition. The procedure typically involves either pulling on a string attached to the stent or using a cystoscope to grasp the coil in the bladder and pull it out through the urethra. While the process is usually quick and relatively painless, some discomfort and pain may be experienced afterward.

What You'll Learn
Kidney stent removal is typically done in a hospital
Kidney stents, also known as ureteral stents, are small, flexible tubes inserted into the ureter to treat or prevent blockages that impede the normal flow of urine from the kidney to the bladder. The most common reason for placing a kidney stent is to treat kidney stones.
Kidney stents are typically temporary, and a urologist will remove them after the patient's condition improves. Most people have stents in for a few days or weeks, but some need them for months or years. The length of time a stent remains inside a patient's ureter depends on the reason for its placement.
In some cases, kidney stents with a string attached can be removed at home by the patient following the guidance of their healthcare team. The patient simply pulls on the string, which hangs outside the urethra and may be taped to the skin. It is recommended to drink water and take pain-relief medication 30 minutes before removing the stent to reduce discomfort.

The procedure takes 1-2 minutes
The procedure for kidney stent removal, also known as ureteral stent removal, typically takes just a few minutes. This procedure is usually carried out in a hospital or surgical centre, and patients are often required to fast for at least eight hours beforehand.
The stent is a thin, hollow tube that is placed in the ureter to allow urine to drain from the kidneys to the bladder. During the removal procedure, a thin, flexible tube called a cystoscope is inserted through the urethra and into the bladder. If the stent has a string attached, the urologist will gently pull on it to remove the stent. If there is no string, a tool called a scope is used to grasp the coil in the bladder and pull it out through the urethra. The patient is then asked to urinate to clear the area.
The procedure itself is not usually painful, but many people experience some discomfort afterward. Local anaesthesia is typically applied to the urethra before the procedure, and patients are advised to drink lots of water in the following days to aid kidney and bladder function.
Most people can resume their usual activities about a day after the procedure, although some may need an extra day or two of rest if they feel tired or experience kidney pain.

Patients may be discharged on the same day
A ureteral stent is a flexible plastic tube inserted into the ureter to treat or prevent blockages that impede urine flow from the kidney to the bladder. The coiled end of the stent sits in the kidney, while the looped end rests in the bladder. In most cases, ureteral stenting takes less than 30 minutes to complete. However, patients may be in a hospital or surgical centre for a few hours while healthcare providers prepare them for surgery and ensure they are healthy before discharging them.
Ureteral stenting is typically a minimally invasive urological surgery and is usually an outpatient procedure, meaning patients can go home on the same day as the procedure. The stent is often removed in a hospital, and the procedure usually takes 1 to 2 minutes. However, in some cases, patients may be able to remove the stent at home by carefully pulling it out via the string attached. If this is a safe option, a urologist will provide specific directions and indicate when to remove the stent.
The removal process typically involves a urologist gently pulling on the string attached to the stent to remove it. If there is no string, a tool called a scope is used to grasp the coil in the bladder and pull it out through the urethra. The patient is then asked to urinate to clear the area. The whole process is usually quick and takes only a few minutes. Local anaesthesia is typically administered during the procedure, and patients can often eat and drive as usual before and after the procedure.
After the stent is removed, patients may experience some pain and discomfort for a few days. It is recommended to drink plenty of water to aid kidney and bladder function and prevent constipation. Most people can resume their usual activities about a day after the procedure. However, if patients feel very tired or experience pain in the kidney area, they may need to rest for an extra day or two before resuming intense activity.

There are different methods for removal
Kidney stents, also known as ureteral stents, are flexible plastic tubes inserted into the ureter to treat or prevent blockages that impede urine flow from the kidney to the bladder. They are typically placed temporarily, for about 3 to 6 weeks, while a patient recovers from a surgical procedure.
There are different methods for the removal of kidney stents:
Cystoscopy
The most common method for removing a kidney stent is cystoscopy. After numbing the area, a urologist will place a thin, flexible tube called a cystoscope through the urethra. This procedure usually takes place in a hospital and, in rare cases, is performed in an operating room under general anesthetic.
String Removal
Some ureteric stents have a string attached, which makes removal quicker and less invasive. The string hangs outside the urethra and may be taped to the skin. To remove the stent, a person simply pulls the string. This can be done at home, following the guidance of a healthcare team.
In-Office Removal
A healthcare practitioner typically removes the thin, hollow tube in the office. To minimize pain, a topical anesthetic is applied to the urethra, and general anesthesia can be requested.
Regardless of the method used, the procedure for removing a kidney stent takes 1 to 2 minutes. Many people experience moderate discomfort or pain after the removal, which usually goes away after a few days.

Removal can be done at home in some cases
A ureteral stent is a flexible plastic tube inserted into the ureter to treat or prevent blockages that impede urine flow from the kidney to the bladder. This procedure is usually performed in a hospital or surgical center by a urologist while the patient is under general anesthesia. The stent is typically placed temporarily for about 3 to 6 weeks, after which it can be removed.
While ureteral stent removal typically takes place in a hospital, it can sometimes be done at home in certain cases. Some ureteric stents have a string attached, which makes removal quicker and less invasive. If this is a safe option for the patient, the urologist will provide directions and specify when to remove the stent. The patient can then carefully pull out the stent by its string, preferably in the morning while taking a bath or a shower.
To reduce discomfort, it is recommended to drink 3 cups of water and take pain-relief medication, such as acetaminophen, 30 minutes before removing the stent. A 2023 study found that most people who self-removed their stents using strings found the procedure easy and had low complication rates. However, there may still be mild discomfort for a few days after the procedure, which can be managed with over-the-counter pain relief.
After stent removal, patients can usually resume their normal activities within a day. However, if they experience symptoms such as severe tiredness or pain in the kidney area, they may need to rest for an extra day or two. In the unlikely event that the string breaks or the stent does not come out, patients should contact their urologist immediately.

Frequently asked questions
A kidney stent, also known as a ureteral stent, is a small, flexible, plastic tube inserted into the ureter to treat or prevent a blockage that impedes urine flow from the kidney to the bladder.
Kidney stones are the most common reason for placing a kidney stent. Other reasons include stricture, or abnormal narrowing of the ureter, and outside forces such as a tumor pushing on the ureter and causing a blockage.
The length of time a kidney stent remains inside the ureter depends on the reason it was placed. Most kidney stents are temporary and are removed once the blockage has cleared. They are typically placed for 3 to 6 weeks, but some people need them for months or years.
Some kidney stents have a string attached, which hangs outside the urethra and may be taped to the skin. If your stent has a string, your doctor may advise you to remove it at home by pulling gently on the string. However, you should never attempt to remove a stent without this string on your own, as it can cause more harm than you might assume.
The procedure itself shouldn't be painful, but many people report feeling some level of pain and discomfort afterward. A 2015 study found that the average pain reported for the removal process was 4.8 out of 10, with 57% of participants reporting moderate to severe pain levels.
