RESUMEN
Hydronephrotic kidney with a differential renal function greater than 55% is defined as supranormal. The signification of this finding remains controversial. In this article, the authors reported a case of supranormal function in obstructive hydronephrosis. Differential renal functions were evaluated after administration of captopril and after pyeloplasty. The role of captopril renography as a prognostic factor for surgery is discussed.

Prolonged hypocalcemia following parathyroidectomy, called hungry bone syndrome, is a common complication of parathyroid surgery seen in 13-30% of cases. In this article, we report the case of a 48-year-old woman with bone pain and multiple brown tumors as the first manifestation of primary hyperparathyroidism due to a large parathyroid adenoma. After parathyroidectomy, the patient presented clinical signs of hypocalcemia consistent with hungry bone syndrome. Scintigraphic and radiographic modifications following parathyroidectomy are described.
