Nephrolithiasis during pregnancy secondary to primary hyperparathyroidism.

Nephrolithiasis secondary to primary hyperparathyroidism infrequently complicates pregnancy. It can cause severe maternal and fetal complications. We present a case of a pregnant woman with nephrolithiasis and primary hyperparathyroidism. We reviewed the management of nephrolithiasis due to primary hyperparathyroidism during pregnancy. We believe that early recognition and timely intervention can significantly reduce the incidence of complications.
