Summary
A new biodegradable ureteral stent made from poly(L-lactide-co-ε-caprolactone) shows promise for preventing complications from forgotten stents. This degradable stent material maintains strength for at least two weeks and is not toxic to cells.
Area of Science:
- Biomaterials Science
- Urology
- Polymer Chemistry
Context:
- Forgotten ureteral stents lead to significant complications in urology.
- Current ureteral stents often require a secondary procedure for removal.
- There is a clinical need for self-removing, degradable ureteral devices.
Purpose:
- To develop and characterize a novel biodegradable ureteral stent.
- To evaluate the mechanical properties and degradation profile of the stent material.
- To assess the biocompatibility of the new stent material.
Summary:
- A prototype biodegradable ureteral stent was synthesized using poly(L-lactide-co-ε-caprolactone).
- The material demonstrated adequate strength and elasticity for stent applications.
- Degradation analysis in artificial urine showed sustained strength for over two weeks, with no observed cellular toxicity.
Impact:
- This novel biomaterial offers a potential solution to the 'forgotten stent' problem.
- The developed stent material is suitable for further development and in vivo testing.
- Successful clinical translation could reduce patient morbidity and healthcare costs associated with ureteral stent management.

01:15Hydrolysis
Overview
Hydrolysis is a chemical reaction in which the addition of water breaks down a polymer into its simpler monomer units. For example, peptides break into amino acids, carbohydrates into simple sugars, and DNA into nucleotides. Enzymes often facilitate these processes.
Hydrolysis Reverses Dehydration Synthesis
Complex carbohydrates can be broken down by breaking the bonds between individual sugar units. The reaction breaks a glycosidic bond as water is added to the compound. The...

01:32Filtration and Urine Formation
The function of the kidneys is to filter, reabsorb, secrete, and excrete. Every day the kidneys filter nearly 180 liters of blood, initially removing water and solutes but ultimately returning nearly all filtrates into circulation with the help of osmoregulatory hormones. This process removes wastes and toxins but is also crucial to maintain water and electrolyte levels. Most of these functions are performed by the tiny but numerous nephrons contained within the kidneys.
02:24Comparative Excretory Systems
Animals have evolved different strategies for excretion, the removal of waste from the body. Most waste must be dissolved in water to be excreted, so an animal’s excretory strategy directly affects its water balance.
