Suggest Treatment To Arrest Additional Growth Of Left Pelvic Kidney Pipe

Hi, Since the birth of my daughter I was advised to do routine urine test. The pre-birth scans detected some extra growth of left pelvic kidney Pipe(dont know the medical name). even after delivery at 3 months and 6 months we did similar scans. 3 months scan was okay. 6 months scan again detected growth of that tube. On Surgen's and Dr's suggestion we did some special PET scan. Since then we have been regulary consulting surgen and padeatrician on monthly basis after doing urine test. Everything was ok and under control. But suddenly this month test revealed puscells to be 18-20 HPF which were required to be in a range of 0-5 HPF. On Surgens guidance we have repeated immediate some special urine test, of which results are awaited in three days time. Just want to understand, in worst case my 10 months daughter will need to undergo sergical operations. We are giving her sporidex on daily basis to control the infection, if any.
