Symptoms of Vesicoureteral Reflux
Sometimes a child with VUR has no symptoms. If a child does have symptoms, the most common is a UTI. When urine flows backward, as it does with VUR, bacteria can grow more easily in the child’s urinary tract, causing a UTI.

Problems with bladder or bowel function can sometimes be related to VUR. A child with VUR is more likely to have

UTIs, including bladder or kidney infections
other bladder problems, such as urinary incontinence, bedwetting, and urinary retention
bowel problems, such as constipation

Most children with VUR who get a UTI recover without other problems. However, in some cases, UTIs can lead to kidney scarring, also called renal scarring, or permanent scars on the kidney. A child is more likely to have kidney scarring if he or she is not treated at all-or not treated fast enough-for a UTI, repeat UTIs, or a high grade of VUR.
