Case Discussion
Case of horseshoe kidney
Most common renal fusion anomaly.
More common in males.
IVU is a useful method for diagnosis, however the isthmus may not be well visualized ; a diagnosis can be made on the basis of secondary sign.
CT is more definitive and the level of fusion can also be determined.
