Primary hyperoxaluria: report of four cases and review of the literature

In this paper we will present four cases of primary hyperoxaluria. All patients had a significant past medical history of polyuria [with or without microscopic hematuria] and polydypsia. All patients had a family history of their parents being cousins. Initial evaluation of all patients by ultrasound and plain abdominal films revealed nephrocalcinosis. Their clinical courses showed gradual loss of renal function over the follow-up years. We will also review primary hyperoxalurias and their management in this report
