Ureteral stent implantation is a procedure to insert (implant) a flexible, soft, plastic tube (stent) into the ureter. The stent supports the ureter while it heals and helps to drain urine from the kidneys. You may have a ureteral stent implanted after having a procedure to remove a blockage from the ureter (ureterolysis or pyeloplasty). You may also have a stent implanted to open the flow of urine when you have a blockage caused by a kidney stone, tumor, blood clot, or infection.
The stent is placed so that one end is in the kidney, and one end is in the bladder. The stent is usually taken out after your ureter has healed. Depending on your condition, you may have a stent for just a few weeks, or you may have a long-term stent that will need to be replaced every few months.
Tell a health care provider about:
- Any allergies you have.
- All medicines you are taking, including vitamins, herbs, eye drops, creams, and over-the-counter medicines.
- Any problems you or family members have had with anesthetic medicines.
- Any blood disorders you have.
- Any surgeries you have had.
- Any medical conditions you have.
- Whether you are pregnant or may be pregnant.
- Allergic reactions to medicines.
- Damage to other structures or organs. Tearing (perforation) of the ureter is possible.
- Movement of the stent away from where it is placed during surgery (migration).
- Ask your health care provider about:
- Changing or stopping your regular medicines. This is especially important if you are taking diabetes medicines or blood thinners.
- Taking medicines such as aspirin and ibuprofen. These medicines can thin your blood. Do not take these medicines before your procedure unless directed by your health care provider.
- Follow instructions from your health care provider about eating or drinking restrictions.
- Do not drink alcohol and do not use any tobacco products before your procedure.
- You may be given antibiotic medicine to help prevent infection.
- Plan to have someone take you home after the procedure.
- If you go home right after the procedure, plan to have someone with you for 24 hours.
What Happens During The Procedure?
- An IV tube will be inserted into one of your veins.
- You will be given a medicine to make you fall asleep (general anesthetic). You may also be given a medicine to help you relax (sedative).
- A thin, tube-shaped instrument with a light and tiny camera at the end (cystoscope) will be inserted into your urethra. The urethra is the tube that drains urine from the bladder out of the body.
- The cystoscope will be passed into your bladder.
- A thin wire (guide wire) will be passed through your bladder and into your ureter. This is used to guide the stent into your ureter.
- The stent will be inserted into your ureter.
- The guide wire and the cystoscope will be removed.
- A flexible tube (catheter) will be inserted through your urethra so that one end is in your bladder. This helps to drain urine from your bladder.
Post Procedure Care
- Your blood pressure, heart rate, breathing rate, and blood oxygen level will be monitored often until the medicines you were given have worn off.
- You may continue to receive medicine and fluids through an IV tube.
- You may have some soreness or pain in your abdomen and urethra. Medicines will be available to help you.
- You will be encouraged to get up and walk around as soon as you can.
- You will have a catheter draining your urine.
- You will have some blood in your urine.
- Do not drive for 24 hours if you received a sedative.
