Hydronephrosis is a common condition that may be diagnosed while your child is still in the womb or after birth. It may resolve itself soon after delivery, but sometimes it may cause problems as your child grows. If there is a blockage present in your child’s urinary system, the kidneys can swell from a backup of urine, known as reflux. If you have been told your child has hydronephrosis, our pediatric urologists and nephrologists can diagnose and manage the cause of your child’s condition. We work with your prenatal team to plan for your child’s assessment and treatment, if needed, after delivery.

Expert Care for Hydronephrosis

Finding the cause of your child’s hydronephrosis is the first step in his or her treatment. It may be caused by a blockage in the flow of urine at some point in your child’s urinary tract. Your child may have an abnormal or unusual kidney or a problem with the valve in the ureter that causes urine to flow backward from the bladder (reflux).

These conditions may be initially diagnosed on an ultrasound during a routine pregnancy exam. Or your child may experience symptoms that will prompt your pediatrician to refer you to a pediatric urologist. In either case, you are in good hands. The pediatric urologists in our nationally ranked program work closely with OB-GYNs, pediatricians, and nephrologists to provide your child with the comprehensive care he or she needs.

Surgery is usually not needed for hydronephrosis, but if your child needs surgery, you can feel confident knowing your child will receive the most effective, least invasive care possible.
