the uroepithelium is an epithelial tissue that lines the distal portion of the urinary tract, including the renal pelvis, ureters, bladder, upper urethra, and glandular ducts of the prostate.

Urothelium is the lining of your urinary tract, including your renal pelvis (in your kidneys), ureters, bladder and urethra. It’s a type of epithelium that protects your blood and tissues from pee (urine) and germs. It also stretches and contracts with your bladder. It’s made of umbrella cells, intermediate cells and basal cells.

Sep 30, 2022 · In this review, we summarize the recent insights into urothelial structure, function, development, regeneration, and in particular the role of umbrella cells in barrier formation and maintenance....

The uroepithelium lines the inner surface of the renal pelvis, the ureters, and the urinary bladder, where it forms a tight barrier that allows for retention of urine, while preventing the unregulated movement of ions, solutes, and toxic metabolites across the epithelial barrier.

The uroepithelium sits at the interface between the urinary space and underlying tissues, where it forms a high-resistance barrier to ion, solute, and water flux, as well as pathogens.

The uroepithelium, or urothelium, lines the renal pelvis, ureters, bladder, upper urethra, and glandular ducts of the prostate and forms the interface between the urinary space and the underlying vasculature, connective, nervous, and muscular tissues (158).

Dec 9, 2003 · The uroepithelium lines the inner surface of the renal pelvis, the ureters, and the urinary bladder, where it forms a tight barrier that allows for retention of urine, while preventing the unregulated movement of ions, solutes, and toxic metabolites across the epithelial barrier.

Jun 10, 2009 · THE UROEPITHELIUM IS AN EPITHELIAL tissue that lines the distal portion of the urinary tract, including the renal pelvis, ureters, bladder, upper urethra, and glandular ducts of the prostate.

The uroepithelium (urothelium) is the interface between the lumen of the urinary tract and underlying tissues. The most superficial layer is composed of large, hexagonal umbrella cells, covered with uroplakins and connected by tight junctions. 1,2. Below is an intermediate cell layer and a basal cell layer connected to a basement membrane.

Nov 1, 2022 · The urothelium (sometimes referred to as uroepithelium) is a stratified, transitional epithelium that lines the renal pelvis, ureters, bladder, and proximal urethra 4. This mucosal surface layer plays an important barrier role, preventing absorption of urine's toxic substances such as acid and urea and defending against pathogen entry from the ...
