Patient: My mother is 50 years old and has left kidney stones, mild effusion, gallstones, kidney stones, and gallstones that have been treated surgically, and in June this year, she had painful kidney stones and went to the hospital to have them treated by percutaneous nephrolithotomy. 3 months after the treatment, she felt that there were still stones and painful recurrence. The largest stone is 1.0*0.8 and is accompanied by hydronephrosis. I would like to ask what measures should be taken since there are still stones and recurrence after surgery. Should we consider medication for stone removal or laser lithotripsy and what should we pay attention to in our daily life?
