Common Complications of DJ Stents: Symptoms, Risks & Management

Summarize with: ChatGPT Perplexity Claude Google AI Grok

A Double J (DJ) stent is a thin, flexible tube placed inside the ureter, the tube that carries urine from the kidney to the bladder. The curled ends help keep the stent in place while allowing urine to drain properly.

A DJ stent may be used when urine flow is blocked or may become blocked, such as with a kidney stone, ureteral narrowing, or after certain urinary tract procedures. It is also commonly placed after kidney stone surgery to help the ureter heal and allow urine to drain freely.

Most people tolerate a DJ stent well, but it can cause some uncomfortable symptoms. Knowing what is normal and which symptoms need medical attention can help you feel more confident while the stent is in place.

DJ Stent Irritation

Stent-related irritation is common. Because the stent sits inside the urinary tract, it can irritate the bladder and ureter and cause symptoms such as:

These symptoms can be more noticeable after physical activity or while passing urine. They are usually temporary and often improve after the stent is removed.

If the pain becomes severe, does not improve with the medicine prescribed by your doctor, or is accompanied by fever or difficulty passing urine, contact your urologist.

Infection Risk

Having a DJ stent can be associated with urinary tract infection, although not everyone with a stent develops one. Symptoms that may suggest an infection include fever, chills, painful urination, worsening pain, or feeling generally unwell.

Antibiotics are not automatically needed just because a stent is present. If an infection is suspected, your doctor may recommend urine testing and prescribe antibiotics when appropriate.

After Stent Removal

Most people feel better after the stent is removed, but some may have temporary bladder or ureteral cramping, urinary urgency, or mild discomfort for a short time. These symptoms usually settle within a day or so.

A small amount of blood in the urine or mild discomfort can occur after removal. However, fever, severe or increasing pain, difficulty passing urine, or significant bleeding should not be ignored and should be reported to your doctor.

Kidney Stent Complication Symptoms

A DJ stent can sometimes cause problems such as blockage, displacement, or infection. Symptoms that need medical attention may include severe or worsening flank pain, fever or chills, vomiting, difficulty passing urine, or a significant increase in blood in the urine.

These symptoms do not always mean that the stent has failed, but they should be assessed by a urologist. Prompt treatment is particularly important if there is a blockage or infection affecting the kidney.

Encrustation and Blockage

If a DJ stent remains in place for a long time, minerals in the urine can build up on its surface. This is called encrustation and, when significant, can make the stent difficult to remove or interfere with urine drainage.

The risk increases the longer some types of stents remain in place. For this reason, it is important to follow the removal or replacement date given by your urologist and not leave a temporary stent in place longer than advised.

DJ Stent Failure Symptoms

A DJ stent may sometimes move out of its intended position or become blocked. Symptoms can include increasing flank or abdominal pain, difficulty passing urine, fever, worsening urinary symptoms, or significant blood in the urine.

These symptoms can have several causes, so they do not prove the stent has failed. Your urologist may need to examine you and, if necessary, perform urine tests or imaging to check the stent and urinary tract.

DJ stent Complications After Removal

Most people have few or no problems after a DJ stent is removed. Temporary cramping, urinary urgency, or mild discomfort can occur and usually settles quickly.

In some patients, the original urinary problem may still need treatment after the stent is removed. For example, if the stent was being used because of a ureteral narrowing or another blockage, your doctor may need to monitor the urine flow and kidney function.

Managing DJ stent Side Effects

Some discomfort is common while a DJ stent is in place, but there are ways to make it easier to manage. Drink fluids as advised by your doctor, take prescribed medicines as directed, and avoid activities that clearly make your symptoms worse.

Your urologist may prescribe medicines to reduce bladder discomfort or urinary symptoms when needed. It is also important to attend your follow-up appointment and have the stent removed or replaced at the time recommended.

Seek medical attention if you develop fever or chills, severe pain that does not improve with medication, repeated vomiting, difficulty or inability to pass urine, or a significant increase in blood in your urine.

Conclusion

DJ stents are commonly used to keep urine flowing from the kidney to the bladder when the ureter needs support. Some urinary urgency, frequent urination, mild bleeding, and discomfort are common while the stent is in place. Most of these symptoms improve after the stent is removed.
Following your urologist’s instructions for medicines, follow-up, and stent removal can help prevent complications. Contact your doctor promptly if you develop fever, severe pain, difficulty passing urine, or heavy bleeding.
