hello,
thanks for your query
Pain on the right side of abdomen and
hydronephrosis on
ultrasound are only demonstrative of an obstruction in your
urinary tract on the right side. A DTPA renal scan needs to be done to know the functional status of that
kidney.If the scan shows a diffential 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
I will be glad to answer any follow-up queries that you may have
thanks
Dr
