title: Urolithiasis and psoas abscess in a 2-year-old boy with type 1 glycogen storage disease.
abstract: We report on a pyogenic psoas abscess secondary to an impacted calcium oxalate ureteric stone in a 2-year-old boy with glycogen storage disease type 1 (GSD-1). The patient had a drainage of the abscess through a flank incision followed by percutaneous nephrostomy and open ureterolithotomy. Metabolic acidosis, hyperuricemia, hypocitraturia, and hypercalciuria appear to be significant in the pathogenesis of urolithiasis in patients with GSD-1. Regular ultrasonography of the abdomen along with optimal metabolic control may delay or prevent urolithiasis and its complications in GSD-1 patients.
