Hydronephrosis in Infants is the enlargement, or dilation, of the renal pelvis - it is the central part of the kidney where urine collects. Hydronephrosis can occur in one or both kidneys. Child’s hydronephrosis can be mild, moderate, or severe — based on how much the kidney is stretched and how much the urinary flow is impaired — and will tell you whether your child’s hydronephrosis affects one kidney (unilateral) or both kidneys (bilateral). More than half of the cases resolve by the time the baby is born or soon after. Prioritise your Newborn's Urological Health at the right time! Book your Appointment Today!
