A ureteric stent is a specially designed hollow tube, made of a flexible plastic material that is placed in the ureter. The length of the stents used in adult patients varies between 22-30cm long
It is designed to stay in the urinary system by having both ends coiled; the top end coils in the kidney and the lower end coils inside the bladder to prevent its displacement. Stents are flexible enough to withstand various body movements. Stents are temporarily placed in the kidney to prevent or relieve obstruction.
They allow urine to pass down the ureter, can help to relieve pain (e.g. from a stone/stone fragments), drain infection or help with kidney function if the kidney is obstructed. Having a stent in place will allow the ureter to heal.
In the majority of patients, stents are required for only a short duration. This may be just a few days. However, a stent can stay in for up to three months without the need to replace it. When the underlying problem is not a kidney stone, the stent can stay in even longer. There are special stents, which may be left in for a much longer time. Your Urologist will tell you how long the stent is expected to remain in place.
A cystoscopy is a procedure where a telescope is used to inspect the urethra (water-pipe), the prostate (in men), and the bladder. A very clear and magnified view can be achieved. A stent is placed during a cystoscopy and could also be inserted as an additional part of an operation in the ureter and kidney (e.g. Ureteroscopy).
On occasions, the stent may need to be placed from the kidney down to the bladder using special x-ray techniques. Radiological contrast dye is injected via a small tube in to the ureter.
A ureteric stent can be removed either with the help of sedation or anaesthesia, or in many cases with flexible cystoscopy and a local anaesthetic lubricant. Sometimes a stent can be left with a thread attached to its lower end that stays outside the body through the urethra. Doctors or patients can remove such stents by pulling this thread.
If there is no thread in place, the Urologist will use a flexible cystoscope to view the ureteric stent and then use special graspers to take it out.
It is a short procedure to remove the stent using a flexible cystoscope. No preparation is required. Please continue to take all your usual medications. You do not need to fast if no anaesthesia is used. There is no restriction on driving after this procedure.

It is common to have some side affects with a ureteric stent. You may experience discomfort or pain in the bladder and kidney (flank) area, but sometimes in other areas such as the groin, urethra and genitals. This discomfort or pain may be more noticeable after physical activities and after passing urine. Bending from the abdomen is often worse.
There might also be an increase in frequency of passing urine, the need to rush and pass urine urgently, a sensation of incomplete emptying of the bladder, or burning/stinging when passing urine. You may also experience a small amount of blood in the urine. This is quite common and the situation can improve with a greater fluid intake. Do not drink excessively. Aim to keep your urine a pale yellow or straw colour.
If you find your urinary symptoms are not improving or become worse, then you could have an infection. You can contact our office or see your GP to organise a urine test.
However, if any of the following symptoms occur then immediately contact our office, your GP or present to a hospital emergency department for assessment;
Excessive bleeding or blood clots in the urine making it difficult to urinate
If you develop a high temperature or begin having flu-like symptoms
Begin vomiting or have ongoing sharp pains that do not respond to pain relief
You should be able to recommence most of your usual activities shortly after surgery. Please avoid heavy lifting or straining. Sexual activity can be recommenced once the bleeding settles.
You should try to drink about 2L of fluids, mainly water, each day the stent remains in place. This will help to cut down the risk of getting an infection and will reduce the amount of blood in your urine. You can take some pain relief (Panadol or Nurofen) on a regular basis. You may want to try some Ural sachets (available from the chemist) 2-3 per day if needed.
You should not drive for at least 24 hours after having sedation / general anaesthetic(or as instructed by your Urologist). You can drive after having stent removal with local anaesthetic only.
Patients who are travelling outside the metropolitan area are required to check when they are able to travel, and will be required to stay in the metropolitan area for 24 hours (or as instructed by your Urologist).
In the event of an emergency, call our office within business hours and speak to our Practice Nurse. If out of hours, please call our office to contact our On-Call Urologist, or present to your nearest Emergency Department.
