Grade IV vesicoureteric reflux - Ganzer Fall bei Radiopaedia
The urinary system consists of the kidneys, ureter, bladder and urethra. With the exception of the urethra, this is the same in both males and females. It spans the abdomen and pelvis, from the upper abdomen to the extreme pelvis, being inextricably linked with the genital system.
The urinary system's prime purpose is the filtration of blood and in so doing, the production, transit, storage and disposal of urine. It is also serves a key role in the regulation of body pH and blood pressure.
