Dear Sir/ Madam, In my CT scan kub report there was a 1) Right kidney approx. 8.8 cm. Calculus of size 10 mm in right lower ureter which shows mild hydronephrosis & hydroureteric changes. Mild stranding of right perinephric fat is seen. I never felt any pain before or any symptoms which occurred in just 2 days. 2) Left kidney 9.5 cm shows calculus of size 7 mm at lower pole. Rest things are normal. Two days back surgeon operated a URS of right kidney & standing. What precautions I should take to avoid surgery of left kidney calculus & medicines which dissolve or break calculus of 7 mm. There is no pain in my left side so far. Pls advise best supplements to avoid these stones in future. Looking forward your best suggestions, medicines. Thanks Nitin kumar.
