Hello, Attached a CT scan report. Right kidney ~ 10.2 x 4.6 cm appears normal. Few (atleast 3) tiny concretions noted at all calyces of right kidney of average size ~1.5-2 mm. No evidence of hydronephrosis seen. Right ureter appears normal, no dilatation/calculus seen. No abnormal perinephric fat stranding / collections noted. Left kidney ~ 10.3 x 4 cm appears normal. A calculus of size 10.5 x 10.3 mm with a mean attenuation of ~1313 HU noted in mid pole calyx of left kidney. A tiny concretion of size ~2 mm noted in upper polar calyx. No evidence of hydronephrosis seen. Could you please suggest weather surgery is the option or some medicine will treat and remove stone?
