What is the urothelial lining?

What is the urothelial lining?

The urothelium is the lining of the lower urinary tract. It comprises multiple layers of cells (the exact number depends upon the species) that functions as a primary barrier as well as exhibiting signaling properties.

What does urothelial mean?

(yoo-roh-THEE-lee-um) The lining of the urinary tract, including the renal pelvis, ureters, bladder, and urethra.

Is urothelial carcinoma the same as transitional cell?

Urothelial carcinoma, also known as transitional cell carcinoma (TCC), is by far the most common type of bladder cancer. In fact, if you have bladder cancer it’s almost certain to be a urothelial carcinoma. These cancers start in the urothelial cells that line the inside of the bladder.

What are bladder lesions?

A lesion in the bladder is a general term that describes some abnormality that occurs in the bladder, the hollow container that holds urine until it’s ready to be expelled from the body. The key to understanding the question is the definition of a “lesion”. Various lesions may range from benign to serious.

What is urothelial carcinoma high grade?

High grade means your cancer is more likely to grow spread and come back after treatment. For example, if you have early (superficial) bladder cancer but the cells are high grade, you’re more likely to need further treatment after surgery. This is to reduce the risk of your cancer coming back.

What is the difference between pelvis and renal pelvis?

renal pelvis, enlarged upper end of the ureter, the tube through which urine flows from the kidney to the urinary bladder. The pelvis, which is shaped somewhat like a funnel that is curved to one side, is almost completely enclosed in the deep indentation on the concave side of the kidney, the sinus.

What is the anatomy of the foot?

The anatomy of the foot. The foot contains a lot of moving parts – 26 bones, 33 joints and over 100 ligaments. The foot is divided into three sections – the forefoot, the midfoot and the hindfoot. The forefoot. This consists of five long metatarsal bones and five shorter bones that form the toes (phalanges).

What does urothelium look like?

Urothelium shows basal cells, which are cuboidal, small, and attenuated, scattered along basement membrane Here the tip of a papilla (upper) is juxtaposed to the wall of the minor calyx (lower). The urothelium, reactive-appearing and lining the minor calyx, ranges from more normal thickness to quite attenuated .

What is the urothelium of the bladder?

The urothelium is the membrane lining the interior of almost the entire urinary tract from kidneys to proximal urethra. The vast majority of bladder tumors arise in the urothelium. In developed countries, approximately 90% of primary bladder cancer is urothelial.

What is the medial column of the foot?

The medial column is more mobile and consists of the talus, navicular, medial cuneiform, 1st metatarsal, and great toe. The lateral column is stiffer and includes the calcaneus, cuboid, and the 4th and 5th metatarsals. Figure 3: Columns of the Foot
