J Neurosurg ; The anti-diuretic hormone arginine-vasopressin AVP is released from the pituitary and regulates water reabsorption in the principal cells of the kidney collecting duct.

The shortage or deficit of antidiuretic hormones provokes the elimination of a great volumen of hypotonic diluted and tasteless urine; this disorder is known as insipid diabetes.

Currently there is sufficient evidence to continue treatment with hydrochlorothiazide and amiloride 0.

The variables considered for analysis include invasion and resection grades. Due to risk of developing extended urinary bladders due to polyuria, the bladder should be emptied regularly to ensure the maximal bladder capacity is maintained within the normal range.

This disorder is caused by the failure of the posterior pituitary to secrete adequate amounts of arginine vasopressin AVPalso called antidiuretic hormone neurogenic or central diabetes insipidusor by the inability of the kidney to respond to circulating AVP nephrogenic diabetes insipidus.

Introduction Diabetes insipidus is a disease characterized by the elimination of high volumes of very dilute urine. The defect of urine concentration is present from birth so that the clinical manifestations could be observed from the first weeks of life. These induce, paradoxically, increase in the activity of cAMP, independently of the action of the AVP, with the phosphorylation of aquaporin-2 and its insertion in the tubular membrane of the nephron.

With these urine samples the osmolality and density and the amount of urine will be determined.

Anatomic insiipida in the renal medulla are frequently seen in patients with primary tubulointerstitial nephropathies, which modify the osmolar gradient dependent on the action of the mechanisms of the multiplication of the countercur-rent and cause the development of polyuria.
