Right kidney is fully active normal size and modern hydronephrosis seen through out last 6 years in several check up.in ultrasound. Dtp scan. Uria Creatine also normal. No protein in urine. 6 years ago post void urine is 180 ml. But now it is 60 ml. 60 ml post void is normal? Such hydronephrosis is harmful for my right kidney? No vur no blockage seen in right one.in MCU test 6 years ago. I got ultrasound in every year. And urea creatinine for check up all are normal. Bt hydronephrosis is not reduce. It is constant from last 6 year. Neither reduce nor increase. Such hydronephrosis is normal for my right kidney in future? And 60 ml post void. I take dynapres 0.4.mg and listen 50 daily. As per my urologist. By bp 135/85. Please sir tell my problem. And what can I do. Please give me details.
