My father is having frequent urination problem for the past 20years. He goes for urination every 2hrs even though he doest feel this as much problem till date. Recently he is telling that he couldn't sleep well in night due to dis problem.so we visited a urogist ch.subbarao in jagadaba,after seeing tests results he told that there much problem. No need to use any medication it's due to age. But in the test results it's mentioned that "renel parenchymal disease". Is there any better solution for my father's problem?
