Kidney Stent Side Effects

Doctor and Kidney Stent Patient

Kidney stent side effects are usually mild but can, in some cases, be severe.  In the majority of patients, kidney stents are required for only a short period of time. This could typically range from a few weeks to a few months.  When the underlying problem is not a kidney stone, the stent can stay in for several months.  


While side effects are usually mild, a stent can sometimes be very uncomfortable.

Some Kidney Stent Side Effects

Some typical side effects of kidney stent include the following:

  • An increased frequency of passing urine;


  • The need to rush to pass urine (urgency);


  • A small amount of blood in the urine. This is quite common and the situation can improve with greater fluid intake.

  • Stents can also result in a sensation of incomplete emptying of the bladder.

  • Very occasionally, especially in women, there is a slight risk of urinary incontinence episodes.

  • Patients with a stent in place will be aware of its presence most of the time.

  • Discomfort or pain, commonly in the bladder and kidney (loin) area. Sometimes this can affect other areas such as the groin, urethra and genitals. The discomfort or pain may be more noticeable after physical activities and after passing urine.

Kidney stent side effects

A patient may experience one or some of these symptoms, especially soon after the ureteric stent is inserted. There is a tendency, however, for some of these symptoms, such as pain while passing urine and blood in the urine, to improve with time.

Kidney Stent and urinary tract infection

The presence of a stent, along with the underlying kidney problem, makes it more likely that a urinary tract infection can develop. If a patient develops urinary tract infection, some of the symptoms may include raised body temperature, increased pain or discomfort in the kidney or bladder area, a burning sensation while passing urine and feeling unwell. This usually requires treatment with antibiotics.

It is essential for patients with a ureteric stent to drink at least 1.5 to 2 liters of fluids (mainly water) every day.  This will help to minimize the risk of infection and will reduce the amount of blood in the urine.  It will also help with the treatment of kidney stones.

Any patient with a stent who experiences bothersome pain can take painkillers for relief, on the advice of a doctor.  If the stent has a thread coming down from the urethra and extends outside the body, then extra care should be taken, to avoid dislodging the thread.

If you have a kidney stent or are about to have one inserted, you should talk to your doctor about all the implications, including side effects and restriction of any activities. Check with your doctor, immediately, if you experience any severe symptoms or if the stent gets dislodged or falls out.
