<s>[INST] I m 56 years old Male. I have Parkinson s since 2014.. since then I pass 100 kidney stones. 8mm 6mm 5mm 4mm 3mm 2mm 1mm. Had ct and ultrasound done.. dont eat food high in oxalate..I did for 3 years from 2011 to 2014 but no more. Doctors here don t seem to worried as long as I keep passing them. But it is painful. What should I do [/INST] Hi, Most small stones in patients with relatively mild hydronephrosis can be treated with observation and acetaminophen. More serious cases with intractable pain may require drainage with a stent or percutaneous nephrostomy. Treatment of nephrolithiasis involves emergency management of renal (ureteral) colic, including surgical interventions where indicated, and medical therapy for stone disease. In emergency settings where concern exists about possible renal failure, the focus of treatment should be on correcting dehydration, treating urinary infections, preventing scarring, identifying patients with a solitary functional kidney. Hope I have answered your query. Let me know if I can assist you further. Take care Regards, Dr Iven Romic Rommstein, General Surgeon </s>
