What side effects are associated with this type of intervention?

Common side effects of treatments for ureteral disease, including degradable stents like the ADVA-Tec Uriprene® Degradable Temporary Ureteral Stent, typically include discomfort, urinary frequency, urgency, hematuria, and infection. While degradable stents aim to minimize long-term issues, they may still cause initial discomfort, urinary symptoms, and potential for incomplete degradation, which can lead to obstruction or infection. Severe complications are rare but can include significant pain, stent migration, and ureteral injury.

What prior FDA approvals exist?

Ureteral stents are commonly used to maintain ureteral patency in cases of obstruction. Traditional stents made from materials such as silicone or polyurethane require removal after a certain period. Degradable stents, like the ADVA-Tec Uriprene® Degradable Temporary Ureteral Stent, are designed to maintain patency and then degrade over time, potentially eliminating the need for a second procedure to remove the stent. While specific FDA approvals for degradable ureteral stents are not detailed, the development of such stents represents an advancement in reducing patient discomfort and the need for additional interventions.

What other types of research exist?

Promising alternatives to the ADVA-Tec Uriprene® Degradable Temporary Ureteral Stent for ureteral disease patients include: 1) Biodegradable stents made from materials like polylactic acid (PLA) that gradually dissolve, reducing the need for a second procedure to remove the stent. 2) Drug-eluting stents that release medications to prevent infection and reduce inflammation, potentially improving patient comfort and outcomes. 3) Smart stents equipped with sensors to monitor ureteral patency and detect complications early, allowing for timely medical intervention.

Ureteral Stent

Degradable Ureteral Stent for Ureteral Disease (URIPRENE Trial)

Q: What is the mechanism of action of this treatment?

Common treatments for ureteral disease include the use of ureteral stents, which are designed to maintain ureteral patency and ensure urine flow from the kidney to the bladder. The ADVA-Tec Uriprene® Degradable Temporary Ureteral Stent, for example, works by providing temporary support to the ureter, preventing obstruction and allowing for healing or resolution of the underlying condition. Over time, this stent degrades and is naturally eliminated from the body, reducing the need for a second procedure to remove it. This mechanism is particularly beneficial for patients as it minimizes the risk of long-term complications, reduces the need for additional surgeries, and improves overall patient comfort and outcomes.

URIPRENE Trial Summary

This trial is testing a new type of degradable stent for safety and performance.

Who is the study for?

This trial is for adults aged 21-80 with unilateral ureteral or renal stones who've had a successful, uncomplicated ureteroscopy. They must be able to fit one of the specified stent sizes and not have urinary tract abnormalities, active infections, severe kidney dysfunction, or certain other medical conditions. Women must use reliable contraception.Check my eligibility

What is being tested?

The Uriprene® Degradable Temporary Ureteral Stent's safety and performance are being tested in this non-randomized study across multiple centers. The stent is designed for patients following an uncomplicated procedure to remove kidney stones.See study design

What are the potential side effects?

While specific side effects aren't listed here, typical risks may include discomfort during insertion or removal of the stent, potential irritation while it's in place, urinary symptoms like frequency or urgency, and possible infection risk.
