i m suffering from frequent urination problem , from last 1 year , in diagnosis i came to know that i have 2 stones in kidney calculus but doctor suggest me that it is not due to stone, even i have already done urodynamic test, in result it has shown that my bladder is perfectly alright, my urologist told me that it is all due to stress, is it so??? please give me any suggestions?? one main point is that mostly i dont feel urgency during night when i am sleeping .
