Normally, urine is made in the kidney and travels down a tube, the ureter, into the bladder. As the bladder fills, the normal ureter becomes compressed, not permitting urine to pass up into the kidney. If this valve does not work properly, reflux will occur. Reflux tends to run in families; therefore, your doctor may recommend that siblings of children with reflux should be checked for the condition as well. How is reflux treated?
