Treatment varies depending on the type of kidney or urinary disease present. In general, the earlier kidney or urinary disease is recognized, the more likely it is to be treatable. Dietary restrictions, drug therapy, and surgical procedures may be appropriate. If the kidneys can no longer effectively remove waste and water from the body, a dialysis machine used several times a week can take over kidney filtration. Kidney transplant surgery is another option when kidneys fail. If you have diabetes or hypertension, control of your blood pressure and blood sugar is extremely important to prevent or minimize kidney damage.
