I have 4 mm stone at upper pole of right kidney and 6.5 mm stone at vuj along with condition of hydronephrosis and hydroureter. My kft, urine culture and x-ray kub were normal (test done on 11th may). Doctor advised me to have deflazacort 30 for 7 days and urimax .4 mg for 3 weeks. It's been 10 days since I started taking medicines (10urimax &7 deflazacort) still stones are not flushed out. How much time is required in general to pass the stones thru urine, what is the success rate and if not successful what should be the next step, is there any other medications which can help.
