Dilemma of oxalosis in end stage renal failure: isolated kidney allograft or hemodialysis.
We report the case of a 10-year-old girl who received a cadaveric kidney transplant for oxalosis after a period of 12 months on hemodialysis. The donor was a 6-year-old child. Cold ischemia was four hours. Diuresis occurred immediately in the operating room. Mean daily diuresis was maintained at 8 liters: first by i.v. perfusion, then by nocturnal continuous nasogastric hydration. In addition to the usual immunosuppressive drugs, she received pyridoxine, sodium citrate, phosphate, hydrochlorothiazide and magnesium. Daily hemodialysis was performed from Day 1 to Day 9 and four additional sessions every other day. The postoperative course was satisfactory. Oxaluria was elevated initially at 1074 mg/24 h (normal < 50 mg/24 h). One year later, mean daily diuresis is still 8 liters, renal function is normal and oxaluria is at 296 mg/24 h. Repeated graft sonography showed no nephrocalcinosis, but mild oxalate deposits are noted on renal biopsy. Isolated renal transplantation was successful in our patient. It allowed us to stop hemodialysis and to avoid extra-renal accumulation of oxalate. Despite this success, we are convinced that long term prognosis is uncertain and liver transplantation should be realized to correct definitely the biochemical defect.
