A kidney stone. The stones can form anywhere in the urinary system.Chronic kidney disease is the slow decrease in kidney function that may lead to permanent kidney failure. A person
who has lost kidney function may need to get kidney dialysis.Kidney dialysisis the process of filtering the blood
of wastes using a machine. A dialysis machine (Figure1.71) filters waste from the blood by pumping the blood
through a fake kidney. The filtered blood is then returned to the patient’s body.
Urinary tract infections (UTIs)
Urinary tract infections(UTIs) are bacterial infections of any part of the urinary tract. When bacteria get into the
bladder or kidney and produce more bacteria in the urine, they cause a UTI. The most common type of UTI is a
bladder infection. Women get UTIs more often than men. UTIs are often treated with antibiotics.
