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: -Urethra. This tube allows urine to pass outside the body. The brain signals the bladder muscles to tighten, which squeezes urine out of the bladder. At the same time, the brain signals the sphincter muscles to relax to let urine exit the bladder through the urethra.

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.

Detailed explanation-4: -Children with a duplex kidney (also called a duplicated collecting system) have two ureters coming from a single kidney. These two ureters can drain independently into the bladder or connect and drain as a single ureter into the bladder. Duplex kidneys can occur in one or both kidneys.
