PATHOLOGY

Detailed explanation-1: -The ureters are bilateral thin (3 to 4 mm) tubular structures that connect the kidneys to the urinary bladder, transporting urine from the renal pelvis into the bladder. The muscular layers are responsible for the peristaltic activity that the ureter uses to move the urine from the kidneys to the bladder.

Detailed explanation-2: -Urine travels from each kidney through a fine tube called a ureter to the bladder, where it is stored.

Detailed explanation-3: -The ureterovesical junction is located where the ureter (the tube that drains urine from the kidney) meets the bladder. Ureterovesical junction (UVJ) obstruction refers to a blockage to this area.
