question: Dear Doctor Chawla, I just had the result of my kidney scan. I don't really understand what it means "both kidneys showed prominence of the pelvi-calyiceal collecting system wich persisted after micturition (however, no hydro nephrosis)" "No obvious renal, ureteric or bladder calculi seen ( however a small fragmented calculi cannot be excluded)" .Could you please explain it to me? is likely there is an infection then? will I need more investigations? what kind of treatment is advised?
