Thanks for your query Your friend has pain in left lumbar region and her USG revealed mild Dilatation of Ureter
and pelvis This is suggestive of a obstruction in ureter mostly due to a calculus Since this was done in Jan please repeat it again to locate the site of a stone now. In the meanwhile take antibiotics ciprofloxacin
an antispsmodics for 5 days.Drink plenty of water.Consult some Urologist
for further treatment.
