My mother was facing stomach and back pain since last 3 days so we undergo her blood test in which her eGFR is down but urea and
creatinine is high. So doctor recommended for ultrasound in which left renal calculi with left side moderate hydronphrosis and a calculus measuring 9 mm at lower calyx and a 14 mm in left pelviureteric junction was found. Now doctor recommended for PCLN surgery for calculus. Pls suggest.
