Suggest Treatment For Pus Cells In Urine

Already i am having kidney stone in left and right kidneys.45 days back i was suffering from chillness, fever for one week, then i got stomack pain, it was uncontrolable so i went one urologist he made surgery through scope to remove stone and pus cells. But still in urine pus cells are there.Doctor told me that to take a scan for left kidney furnction. So i want to ask you how many days will take to cure the pus cells and also ask you if kidney function is not proper the pus cells will not cure. is it true. Already i made surgery to remove the stone in left kidney before 3 years.
