3 year old with growing kidney cyst

Posted By JM on February 18, 1999 at 16:59:53:







My three year old had reflux surgically corrected when she was two.  In a follow-up ultrasound her pediatric urologist found a cyst on her kidney that was growing.  He knew it was growing because he returned to her pre-surgical films and found the previously undetected cyst, very tiny at the time.
I have read alot about kidney cysts (from your site and others) and it appears that simple kidney cysts in children are very rare.  Is this true?   Do you have any statistics on this subject?  We hope that hers is a simple kidney cyst but also want to be well-prepared for dealing with the possibility or probability of polycystic kidney disease if necessary.
Thanks for your time.
