Summary
Ureteroscopy for ureterolithiasis is effective, but late complications like vesicoureteral reflux and ureteric stricture can occur. Stone size and density, especially in the lower ureter and above 1000 HU, increase complication risk.
Area of Science:
- Urology
- Endourology
- Nephrology
Background:
- Ureteroscopy is a minimally invasive procedure for ureterolithiasis.
- Contact lithotripsy is often used with ureteroscopy.
- Understanding late postoperative complications is crucial for patient outcomes.
Purpose of the Study:
- To analyze the causes and characteristics of late postoperative complications after ureteroscopy with contact lithotripsy.
- To identify risk factors associated with these complications.
Main Methods:
- Retrospective analysis of 1372 patients undergoing ureteroscopy with contact lithotripsy or lithoextraction.
- Evaluation of complication rates, types, stone characteristics (size, location, density), and patient outcomes.
Main Results:
- A 6.9% complication rate (96/1372 patients) was observed.
- Vesicoureteral reflux (84.4%) and ureteric stricture (15.6%) were the primary late complications.
- Complications were more frequent with lower ureter stones ≥1.0 cm and stones with density ≥1000 HU.
Conclusions:
- While ureteroscopy is generally safe, late complications can occur.
- Stone size and location, along with stone density, are significant risk factors for postoperative complications.
- Further research may focus on preventative strategies for high-risk patients.

When a solid is dipped inside a liquid, the liquid surface becomes curved near the contact. For some solid–liquid interfaces, the liquid is pulled up along the solid, while for others, the liquid surface is convex or depressed near the solid surface. This phenomenon can be explained using the concept of cohesive and adhesive forces.
The adhesive force is the molecular force between molecules of different materials, that is, between the molecules of the solid and the liquid. The cohesive...

01:19Contact-dependent Signaling
47.0K
Contact-dependent signaling, as the name suggests, requires that communicating cells be in direct contact with each other. This is achieved either through receptor-ligand interactions or by specialized cytoplasmic channels that allow the flow of small molecules between cells. In animal cells, channels called gap junctions facilitate contact-dependent signaling in certain tissues, whereas, plasmodesmata perform a similar function in plants.

821
DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...

For most patients, experiencing several weeks of polyuria, polydipsia, fatigue, and significant weight loss may indicate the presence of diabetes. Furthermore, adults displaying the phenotypic appearance of type 2 diabetes (particularly those who are obese and not initially insulin-requiring), may have islet cell autoantibodies, suggesting autoimmune-mediated β cell destruction and a diagnosis of latent autoimmune diabetes of adults (LADA). The categorization of glucose homeostasis is...
