title: Struvite staghorn calculi in crossed fused ectopia.
abstract: Two patients with a struvite staghorn calculus in crossed fused renal ectopia are described. The susceptibility of these patients to urinary tract infection is discussed as is the anomalous extrarenal arterial vasculature to the ectopic and non-ectopic kidneys. Both patients were treated successfully with anatrophic nephrolithotomy and each has remained free of recurrent calculous disease to date.
