My mom had several stomach pain and upon checking CT KUB,we were said that mild hydroureteronephrosis,calculus measuring about 6mm in right VUJ,slightly Edemaous in right VUJ,caculus of 3mm in mid pole,Right
kidney measures 10.3 x 4.7cm. The doctor was literally threatening us that my mom need to undergo surgery immediately else it will lead to kidney failure. But when I consulted another doctor he said that it doesn't require surgery and could be cured by medicines itself. Attached the CT report. Please advise.
