Follow-up
Complications
- All forms of hyperoxaluria are associated with recurrent urolithiasis.
- Primary hyperoxaluria may result in renal failure due to nephrocalcinosis.
Prognosis
- The prognosis of enteric and mild hyperoxaluria is favorable if medical management and dietary modifications are followed. Periodic retesting using 24-hour urine assessments should be performed regularly to monitor compliance and treatment effectiveness.
- The prognosis of primary hyperoxaluria depends on early treatment and management of hyperoxaluria and associated renal deterioration. If medical treatment cannot help the patient maintain a normal oxalate level, nephrocalcinosis may develop, with subsequent renal failure. In this situation, combined liver-renal transplantation is necessary for cure.
