An year back I was detected with a calculi in my right kidney.  They installed a stint and did lythotripsy to remove it.  In the final sonography report they said that the calculi was completely removed but I had a mild hydronephrosis which will go away in around 6 months.  Now, after an year I had another sonography and found that there was a moderate hydronephrosis still there.  They suggested I get my blood creatinine test done.  This test suggested normal level of blood creatinine.  Please suggest what should I do now? What could be the reason for Hydronephrosis?
HIIT is possible that you might have formed new stones in your kidney and one of them had Chat Doctor. In the first instance you will need CT scan of the kidneys to find the cause.
