Secondary Oxalosis



Secondary Oxalosis


Lynn D. Cornell, MD










Oxalosis and chronic renal failure developed 1 year after gastric bypass surgery in a 69-year-old woman (Cr 2.7 mg/dL). Focal interstitial fibrosis and tubular atrophy image, along with calcium oxalate crystals, are evident.






Oxalate crystals are easily appreciated with polarized light, as shown here in a biopsy performed for chronic renal failure after gastric bypass.
