Hai.with most of the stronger investigation done already ur neurological, abdominal system look normal.my strong suspicion is regarding juvenile diabetes (iddm),or any kifney disorder.U can go for these investigations:fasting blood sugars, hba1c, post prandial levels, serum creatinine, blood urea,Ct kub to rule any obstructionSerum electrolytes, Most probably the diagnosis could be kidney parenchmal disease, relating to diabetes.Good luck take care
