Prognostic Model for Vasopressor Requirement After Retroperitoneal Adrenalectomy for Pheochromocytoma: A Retrospective Study.

Objectives: To evaluate the risk factors for postoperative vasopressor requirement among patients with pheochromocytoma undergoing retroperitoneal adrenalectomy. The primary outcome was postoperative hypotension requiring vasopressor support.

Design: A single-center retrospective observational study.

Persistence of primary hyperparathyroidism: a single-center experience.

Background: Parathyroidectomy is the only definitive treatment for primary hyperparathyroidism (PHPT). Precise localization of abnormal glands is a key to a successful surgery. Most patients are expected to be successfully treated with focused parathyroidectomy.
