title: [Urine specific gravity and osmolarity in hypertension patients with dehydration].
abstract: Results are reported from the comparative investigations of kidney concentration function by urine specific gravity and its osmolatity of 58 patients with arterial hypertension. Significant differences were found in more of the half of the patients. On the base of certain theoretical prerequisites and possibilities of technical errors was concluded that the determination of the maximal urine osmolality is a more reliable and more accurate index for the actual renal concentration ability. Urine specific gravity can be used in the everyday clinical practice due to the more convenient and easier determination. Urine osmolality must be used predominantly in scientific-clinical studies.
