While speculations regarding the pathogenesis of this occurrence have been published, heterotopic ossification is still poorly understood. We report the finding of extraosseous bone formation in the renal pelvis of a 30-year-old male patient with a history of kidney stones. Histologic sections of the ureter and renal pelvis showed submucosal nodules of woven bone.
