Abstract
The urinary tract is designed to collect and transport the continuously produced urine volume. Storage and voiding are controlled voluntarily. This complex system has to fulfill various important functions: protection against ascending infection, prevention of crystallization and stone formation, and limitation of maximal pressure, which might disturb glomerular and tubular function. The pelvis, ureter, bladder, and urethra form an interesting physiological system. The calyx, pelvis, and proximal ureter collect the urine from the various papillae and collectively act as an intermediate storage space. When a certain amount of distension of the pyeloureteral junction is reached, an excitation wave from the calyces is conducted down the ureter by rhythmic peristalsis that does not completely empty the pelvis.
