3-3. THE URETERS
Each ureter is a continuation of the cuplike calyces and renal pelvis. The ureter extends from the renal pelvis to the base of the bladder as a cylindrical tube. Each tube is about 25 to 30 cm long (10 to 12 inches) and 4 to 5 mm (1/5 inch) in diameter. Each consists of three layers: an outer adventitial layer, a muscular layer, and an inner epithelial lining. See figure 3-5.
