RESUMEN
Hyperparathyroidism is a desease caused by increase of parathormone secretion, leading to a misfunction of calcium metabolism. Although not very common among population in general, it is frequently observed in patients with cronic renal disease. It can involve a slight syntomatic form, but as a whole, its main repercurssions occur in skeletic muscles, urinary and intestinal systems. The authors conduct a broad revision of the literature, focusing on the methods of diagnosis and spot checking before and during the operations of parathyroid glands. Surgical recommendations, tatic aspects and types of surgery to be implemented are discussed. A systematization for adequate surgical technics performed at the General Surgery Service of Clementino Fraga Filho Hospital of Federal University of Rio de Janeiro is fully discribed and recommended.
