INTRODUCTION: Secondary hyperparathyroidism (SHP) is a common and serious complication of chronic kidney disease (CKD), with a negative impact on morbidity and mortality. Despite advances in the clinical management of SHP, treatment failure still occurs in a significant number of patients. In such cases, parathyroidectomy (PTx) is indicated. OBJECTIVE: To have an overview of the prevalence of severe SHP and of its surgical treatment in hemodialysis (HD) patients in Brazil. METHODS: This was an observational and descriptive study. Data were obtained from questionnaires posted to 660 dialysis units (DU). RESULTS: Results are expressed in absolute values and percentages, or means and standard deviation, as appropriate. 226 (34%) DU answered the questionnaire, providing data about 32,264 HD patients. The prevalence rate of severe SHP (PTH > 1,000 pg/mL) was 10.7 % (n = 3,463). 68 hospitals countrywide perform PTX. Around 40% of them are university centers. 49 (21.7%) DU reported not to have a specialized medical center to refer their patients with severe SHP. 74 (33%) DU reported that the time interval between surgery indication and its performance was over 6 months. The main recognized obstacles to surgery performance were: difficulty to perform the preoperative exams, lack of head and neck surgeons and the long waiting time. CONCLUSIONS: Although severe SHP is highly prevalent in Brazil, a significant number of patients do not have access to PTx. Better public health policies and liaison between nephrologists and head and neck surgeons are urgently required to change this reality.
