Summary
Ureteral stents are evolving beyond traditional double-J designs. New materials and self-expanding options offer improved solutions for ureteral obstructions and future drug delivery applications.
Area of Science:
- Urology
- Biomaterials Engineering
- Medical Device Innovation
Background:
- Conventional ureteral stents (double-J stents) have been standard for nearly 30 years.
- Ongoing advancements are prompting significant changes in stent materials, designs, and applications.
Purpose of the Study:
- To review recent developments and future trends in ureteral stent technology.
- To highlight innovations addressing limitations of conventional ureteral stents.
Main Methods:
- Review of recent literature on ureteral stent advancements.
- Analysis of new stent designs and their clinical implications.
Main Results:
- Advances in ureteroscopy have decreased the need for double-J stent insertions.
- New stent types, including coiled metal and self-expanding stents, are emerging for malignant ureteral obstructions.
- Stent-based drug delivery represents a future application.
Conclusions:
- The field of ureteral stenting is rapidly evolving, moving beyond traditional double-J stents.
- Next-generation ureteral stents will offer personalized solutions tailored to individual patient needs.

01:25Urinary Tract Calculi VI: Surgical Management
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...
01:22Imaging Studies V: Intravenous Urography and Retrograde Pyelography
IntroductionIntravenous Urography (IVU) and Retrograde Pyelography (RP) are important diagnostic imaging techniques used to evaluate the urinary system. These methods help identify structural abnormalities, obstructions, and functional issues in the kidneys, ureters, and bladder. Both procedures use iodine-based contrast media to enhance the visibility of urinary tract structures on X-ray images, though they differ in their methods and indications.1. Intravenous Urography (IVU)Intravenous...
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)...

AssessmentSubjective Data: Obtain a detailed health history, including any recent or chronic urinary tract infections, periods of immobilization, previous episodes of renal calculi, and medical conditions such as gout, benign prostatic hyperplasia, or hyperparathyroidism. Review the medication history for drugs that may influence stone formation, including allopurinol, analgesics, loop diuretics, or thiazide diuretics. Document the use of long-term indwelling catheters and any past surgical...
01:22Ureters
The ureters are retroperitoneal tubes located on either side of the vertebral column. They are responsible for transporting urine from each kidney to the urinary bladder. These tubes have thick walls and are approximately 25-30 cm long. Their diameter is around 10 mm at the renal pelvis, gradually narrowing to 1 mm as the ureter obliquely enters the posterior bladder wall through the ureteric orifices. The shape of these orifices is slit-like, which helps to prevent urine backflow toward the...
