of finding a duplex kidney (duplicated collecting system) is not uncommon. Duplicated collecting systems are almost always asymptomatic incidental findings. Duplication of a ureter might be partial or complete. The kidneys go through a complicated series before you are born. When one of those steps are missed or performed in an unusual manner it can cause an abnormality. We present a case for review in which the patient was experiencing flank pain that turned in to kidney stones lodged in a
