My daughter had corrective surgery for kidney reflux in 2002 at the age of 5. She is now 11 and has been infection free since surgery until a month ago. She was able to get rid of the bacteria with antibiotics, but still has blood in her urine and crystals are also present. Because of her history, and scarring to her kidney, she is being sent to a kidney specialist. My question is: is it possible for surgery to be required again? Is it possible for the "correction" to reverse or be outgrown? Her pediatrician is concerned with her being high risk for kidney stones with the crystals present and also concerned with what is causing the blood.
