from the engine to the tires. With CVT, diameters of the areas where the two pulleys meet the belt can be infinitely varied (Figure 1). Each pulley consists of two conical plates facing each other, which by moving closer or further apart, changes the diameter of the area meeting the belt (Figure 2).
What is Ureteropelvic Junction Stenosis (UPJ Stenosis)? It is one of the most common benign diseases causing renal pelvis dilatation. It mosttly occurs in children and is mainly congenital (from birth). Ureteropelvic junction (UPJ) is the point where the ureter meets the renal pelvis. Renal pelvis is like a 'sink' collecting urine produced by the kidney, while UPJ is the 'sink-trap' (siphon) through which the urine has to pass so that it will end to the bladder through the ureter.
The features observable on the inside of the bladder are the ureter orifices, the trigone, and the internal orifice of the urethra. The trigone (also known as the trigonum vesicae and as the trigone vesical)** is a smooth triangular region between the openings of the two ureters and the urethra.he bladder expels urine into a tube called the urethra that leads to the exterior of the body. Elimination of urine occurs by a process called micturition-which is also known as urination.
