A ureteral stent is a soft plastic tube with holes, temporarily inserted into a ureter to help drain urine into the bladder. One end goes into the kidney, and the other end goes into the bladder. A coil on each end keeps the stent in place. The stent can’t be detected from outside the body. It should not interfere with your normal activities. Your stent will be inserted by a urologist (physician trained in treating the urinary tract) or another medical specialist. The procedure is performed in the hospital or the Outpatient Surgery Center located in the St. Joseph Hospital Outpatient Pavilion. You’ll probably go home the same day.
When Is a Ureteral Stent Needed?
A ureteral stent may be needed:
- To bypass a blockage in a kidney or ureter.
- During the kidney stone removal.
- To allow a ureter to heal after surgery.
Before Your Procedure
Your doctor will give you instructions to prepare for the procedure. X-rays or other imaging tests of your kidneys and ureters may be performed beforehand.
During Your Procedure
- You receive medication to prevent pain and relax or sleep during the procedure. Once this takes effect, your procedure starts.
- The doctor will insert a cystoscope (lighted tool) through the urethra and into the bladder. This shows the opening to the ureter.
- A thin wire is gently threaded through the cystoscope, up the ureter and into the kidney. The stent is inserted through the wire.
- A fluoroscope (X-ray machine) is used to help position the stent.Once the sent is in place, the wire and cystoscope are removed.
While Having a Stent
- You may be prescribed medication to control pain or bladder spasms or to prevent infection. Take this as prescribed.
- Drink plenty of fluids to flush out your urinary tract.
- Your urine may be slightly pink or red. This is due to bleeding caused by minor irritation from the stent. This may happen on and off while you have the stent.
How Long Do You Need a Stent?
The stent is typically taken out after the blockage in the ureter is treated and has healed. This can take one to two weeks, or longer. If a stent is necessary for a long time, it may need to be changed every few months.
Call Your Doctor Should You:
- Have urine containing blood clots.
- Constantly leak urine.
- Have a fever greater than 100.4°F, chills, nausea or vomiting.
- Your medication does not provide pain relief.
- The end of the stent comes out of the urethra.
