Hi My self Kavya, from Bangalore Age 25 years. I have only one kidney (right) from birth. I had undergone surgery for 2 times pyeoplasty. First surgery in 1999 & 2nd in 2004. After 13 years got a pain in the place of surgery. I had completed all the necessary tests which prescribed by urologist. In the Ultra sound scan the impression is Mild Hydronephrosis is diagnosed. Could anyone suggest me what are the treatment required. Is it mandatory to undergo a surgery again. Is there any permanent solution for this. Waiting for the response at the earliest.
