ABSTRACT
Part I: THE URINARY SYSTEM AND URETERIC STENTS The Urinary System and the Ureter The kidneys produce urine. Normally there are two kidneys situated in the upper part of the abdomen, towards the back. The urine formed in the kidney is carried to the bladder by a fine muscular tube called a ureter. The urinary bladder acts as a reservoir for the urine and when it is full it is emptied via the urethra (water passage).
