Kub ultrasound finding of anechoic focus at the middle pole measuring 1.5x1.5cm, left kidney. minimal pelvocaliectasia right kidney.what treatment?

Probably nothing: Anechoic means a cyst. Simple anechoeic cysts are benign. Mininal pelvicaliectasis is also of doubtful significance but somewhat depends on what is going on with you.

Probably benign: A description of an anechoic focus in the kidney typically refers to a cyst or a cystic lesion. Minimal pelvocaliectasis typically refers to very mild dilatation of the pelvis & calyces which is where urine drained into before it flow out into the ureter. These findings do not sound concerning as pelvocaliectasis may occur when you have a full bladder. Please check with your doctor to be sure.
