question: Hi doctor, My husband is having a severe pain in the stomach and spine for the past three days, and we took a scan today which says the right kidney measures 10.6 x 3.9 cm, left kidney measures 11.2 x 5.5 cm, calculus measuring 3 mm is noted in the left distal ureter, just proximal to the vesicoureteric junction, left distal ureteric calculus causing mild hydroureteronephrosis. Do this need surgery or can it be cured with medicine?
