I have a tiny calculus measuring about 0.2 cm at the interpolation region of left kidney. The right pevicalyceal system is compact .The ureter is normal in course and calibre. And there is a mild left hydrouretero-nephrosis due to a proximal left ureteric calculus measuring 0.5 cm and located 4.3 cm distal to the pelvic-ureteric junction. There is minimal left perinephric and periuretheric stranding on the left side. I am experiencing very mild burning sensation when I urinate. Can this situation be treated by medication? Thank you in advance.
