Essential Guide To Ureteral Stents The Basics You Need To Know
By Dr. David Samadi
One of the most common procedures urologists perform is the placement of ureteral stents. The ureters, essential muscular tubes that facilitate urine transport from the kidneys to the bladder, can sometimes become narrowed or obstructed, impeding proper urine drainage. In such cases, urologists often turn to ureteral stents to maintain the openness of these vital pathways.
Ureteral stents are slender tubes typically made of flexible polyurethane or silicone. They measure approximately 10-15 inches long and about ¼ inches in diameter. A urologist inserts these devices to span the length of the ureter, ensuring it remains expanded and free from blockages.
What are the reasons why someone may require a ureteral stent?
The primary indication for a ureteral stent is to facilitate urine flow around kidney stones that obstruct normal passage. Additionally, they are employed to manage the passage of fragmented stones post-breakage. Stents can also alleviate blockages stemming from postoperative swelling of the ureter.
Furthermore, urologists prescribe ureteral stents for conditions such as:
- Blood Clots: Originating from various sources like bladder infections, prostate infections, or ureteral stones, blood clots in urine can lead to severe pain and hinder urination.
- Inflammatory Bowel Disease (IBD): Swelling in the ileum can exert pressure on the ureter, impeding proper drainage.
- Scar Tissue Build-Up: Whether due to surgical procedures, trauma, or health conditions like endometriosis or cancer, scar tissue can constrict the ureter, causing urine backup.
- Ureteropelvic Junction Obstruction: A congenital condition where narrowing of the ureter occurs, hindering urine flow.
What happens during and after the procedure
Regarded as a minimally invasive procedure, a ureteral stent placement is commonly performed on an outpatient basis, providing patients with the opportunity to recover in the comfort of their own homes on the same day. Anyone who’s just had a ureteral stent placed should not drive immediately post-operation due to anesthesia effects. The procedure itself is conducted under anesthesia to ensure patient comfort.
Following stent placement, patients are advised to increase water intake to support kidney and bladder function. It’s common to experience intermittent blood in the urine and mild discomfort initially, which typically resolves within a few days.
Generally, ureteral stents are temporary and removed within days to weeks after placement. In some cases, however, such as when managing tumors or prolonged obstructions, stents may remain for months or even years.
When to Consult a Specialist
Patients experiencing symptoms such as changes in urine production, abdominal or lower back pain, fever, nausea, vomiting, difficulty urinating, or recurrent UTIs should promptly consult a urologist. These specialists can diagnose ureteral obstructions through urine and blood tests, and imaging techniques like MRIs, CT scans, or ultrasounds.
Treatment may involve the use of medical devices like ureteral stents to alleviate symptoms and resolve underlying issues.
Seeking timely medical attention ensures effective management of ureteral blockages and associated urological concerns, enhancing overall health and well-being.
