Hello Doctor , My Father having severe pain in his lower stomatch. Intially the doctors suggested that it could be due to acidity. However when the pain got severe, i was asked to take a scan. The scan report suggest that, He has Left Mild Hydroureteronephrosis. I am not sure of the technical word. Is this something to worry. Is it related to kidney stone. If yes, can the same be cured by tablets itself. How long woutd it take for my father get back to normal. Guess i am asking too many questions, reason being i am worried.
