Hello Dr. Rynne my child was diagnosis with pelviectasis I didnt not get factual info has what cause s this & can it be treated permanently also how to prevent this from recurring, if possible I am just needing to know will this cause serious kidney issue s thanks.
HY Chat Doctor.  It is generally caused due to a blockage along the babies urinary tract, making urine backflow into the kidneys and making it dilated in the process. It may hamper kidney function and even render it ineffective unless steps are taken to relieve the obstruction. If the obstruction is removed, there is less chance of recurrence. However, the damage already done may not be undone. Recurrence in case of your subsequent baby is unrelated, and you need not worry about it.
