hi thambi, you have stones in both kidneys and one lodged in your right upper ureter. luckily the stones are 6 mm or smaller. so medical treatment is preferrable. take lots of fluids (unless you have any heart/kidney or liver problems). take citrus juice (lemon/mausambi/orange). your family physician or a urologist may prescribe you medicines to decrease pain/avoid infection/ help expell the stones. flush therapy can aslo be given if fluid intake is less. get a repeat sonography done after 7-10 days. if you have severe pain/vomiting/fever or if the ureteric stone refuses to move even after 10-15 days of flushing, endoscopic surgery may be needed. good luck.
