Summary
Ureteral stents cause discomfort and infection risks for many patients. New stent designs and materials aim to reduce these common, bothersome side effects and complications.
Area of Science:
- Urology
- Biomaterials Science
- Medical Device Engineering
Background:
- Ureteral stents are crucial in managing various urological conditions.
- Indwelling ureteral stents frequently lead to patient discomfort and increased urinary tract infection (UTI) risk.
- Stent encrustation is a significant complication, causing patient morbidity.
Purpose of the Study:
- To review current challenges associated with ureteral stents.
- To explore advancements in ureteral stent technology.
- To highlight strategies for mitigating stent-related complications.
Main Methods:
- Review of existing literature on ureteral stent complications.
- Analysis of emerging biomaterials and coating technologies.
- Examination of drug-eluting technologies for stent applications.
Main Results:
- Ureteral stents are associated with a high incidence of bothersome symptoms.
- Urinary tract infections and stent encrustation are common complications.
- Novel biomaterials, coatings, and drug-eluting technologies show promise in addressing these issues.
Conclusions:
- Ongoing research focuses on improving ureteral stent design.
- New technologies aim to enhance patient comfort and reduce complications.
- Future developments seek to minimize the adverse effects of ureteral stenting.

01:30Urinary Tract Calculi III: Medical Management
The diagnosis of renal calculi involves several imaging techniques, including non-contrast CT scans and ultrasound. These methods help visualize kidney stones, assess their size and location, and detect possible obstructions. Additionally, Measuring urine pH is useful for diagnosing specific stone types, such as struvite (alkaline pH) and uric acid stones (acidic pH). Cystine stones are primarily linked to cystinuria, a genetic condition. A urinalysis helps detect blood in the urine (hematuria)...

Procedures for Kidney StonesMedical intervention is necessary when kidney stones or renal calculi are too large to pass spontaneously (typically greater than 5 millimeters) when stones are accompanied by symptomatic infection (such as fever or pyelonephritis), when they impair kidney function, or when they cause persistent symptoms like severe pain, nausea, or urinary retention. Additionally, patients with only one kidney or those who cannot be treated with medical management also require...
