Hello and thanks for the query
According to your USG report you have written it seems that their is obstruction may be due to ureter
stone (not seen in USG) which is causing Hydronephrosis
and hydro Ureter. But the problem is you have been not diagnosed yet for the cause of obstruction.
The further investigation you needs are IVP in which a die in given through i.v. line and X-ray of KUB are taken at regular intervals.
If IVP can't help your doctor to get to a diagnosis than you may need CT Abdomen. This will surely help you.
I don't know any doctor in Jaipur but you can search for Urologist
in Jaipur in google. Hope this will help you.
Best Wishes and have a speedy recovery.
