<s>[INST] hi doctor i have the stone in upper cylax 6mm and 5mm in kidney.there is often little bit burning in a penis. i have checked the last month urine test. there was 2-3 rbc and now i have again checked the urine test again. there are 2-3 pus cells found. i am treating the stone with lithotripsy. but i want to know there is any concern to my health. does pus cells effect my health or not.i am taking exercise very hard for 35 minutes.i am worried about the pus cells.i have been going through this for six month. [/INST] Thanks for asking on Chat Doctor. The pus cells in the report are not alarmingly high. These few pus cells and RBC can come from the stone rubbing against the epithelium. Burning pain could be due to the stone or slight infection which is due to stone and obstruction in urine flow. Stones can be formed due to deny Chat Doctor.  Sometimes parathyroid secrete high parathormone which increases calcium in blood causing stones. Some stones made of service could be due to some ammonia splitting bacteria. The best way out is to take in a lot of water to keep salts from accumulating in the tubes. Hope it helps </s>
