A DTPA renal scan needs to be done to know the functional status of that kidney. If the scan shows a differential function of less than 10% with normal functioning opposite kidney, then it will be considered to be non-functional. I hope I have answered your query will be glad to answer any follow-up queries that you may havethanksDr</s>
