Sir I have one kidney. The right sided kidney was operated at the age of 5 months. I am 20 years old now. I have been living life normally till now. But a few months back I got a very little problem with my kidney. It was a mild hydronephrosis. I saw a good urologist. He tested all the tests he needed to do. He tested dtpa-renogram+lasix. There split function of my left kidney was 99.8%.my s. The creatinine score was 1. After all the tests he said there is nothing to worry about. He didn't gave me any medicine. Just kept me in observation for 6 months and gave one vitamin tablet. Now my question is what does the split function option in dtpa-renogram means? Does it indicate my kidney function? Is there anything to worry? If not then what about the mild hydronephrosis? Will it be cleared automatically? He suggested me to eat a bit less as I used to feel loin pain in left side after filling my stomach. Eating less doesn't cause that problem much. I am still tensed sir. I am a good looking man studying in a well reputed university. I got a life to live. Never felt this down and tense in 20 years!
