I checked residual urine twice and the results were 7ml and 1ml. But I doubt these results because I heard a urologist should check residual urine when the patient urinate more than 150ml, but I didnt. Last night I urinate again(150ml) 30 minutes after last urination (200ml). I'm afraid whether this means residul urine in my bladder.
Plus, I urinate 150-200ml per void. Is this normal?
