The issue is related to my father aged 59 years. He has been diabetic patient from past 20 years and in the year 2019, his CABG surgery was operated. Now, in recent report, it was found that he has calculus of 8mm at the right ureter with mild upstream hydrouteronephrosis. I request your kind consideration & help. It was reported in August his creatinine level was at 2.5 and on 9th Sept his creatinine was at 3.5(calculus effect) and on 21st Sept it was at 3.25. Please kindly provide us kind inputs what should be done with the report attached.
