Objective: To present a case report of crossed fused renal ectopia treated with percutaneous nephrolithotomy at our hospital and to perform a literature review.

Methods/results: We present the case of a male with renal calculi in a crossed ectopic and fused kidney, treated satisfactorily with percutaneous nephrolithotomy in a one-stage surgery through an upper pole access

Conclusions: Percutaneous nephrolithotomy is a minimally invasive procedure with good results and low morbidity in this kind of patients. It is technically demanding and requires surgeon's ability and experience.
