My mother was having Hematuria for several weeks accompanied by severe pain in right loin, fever and sudden chills at night. USG report and other blood reports came perfectly normal but investigating it further by doing a CECT KUB had the following findings: - Calculus (6.3x4.7mm) in lower major calyx of right kidney - mild dilation of right pelvicalyceal system with a vessel seen passing over the right pelviureteric junction Now, hematuria has stopped but mild pain in loin area still persists. Currently continuing Potrate SF solution twice daily. Is RIRS and laser lithotripsy required for the stone removal?
