Minimally Invasive Approaches for Stone Clearance in Crossed Fused Renal Ectopia.

Crossed fused renal ectopia (CFRE) is a rare fusion anomaly of the kidneys, with a predisposition to calculus disease. Management of renal calculi in CFRE is not standardized because of paucity of literature. We managed a 32-year-old man with left to right CFRE with multiple stones in both the kidneys by percutaneous nephrolithotomy for the right moiety and laparoscopic pyelolithotomy for the crossed moiety.
