Hello and welcome to Chat Doctor. As a Urologist, let me opine, that your scan report shows, 1. A 7 mm stone in lower part of Right kidney.2. A 6.5 mm stone in the upper part of Left kidney.3. The right upper part of tube Chat Doctor.  This will need treatment, as they're large. The right ureteric stones must be cleared first, as that side kidney is blocked, and kidney function will be affected. This can be done with endoscopic surgery.(URS-lithotripsy). If you've any other doubts, you may contact me with a direct question.
