    Urinary osmolality was measured with a density test (specific gravity) using the Atago refractometer PAL-10S BLT/A+W (Atago, Tokyo, Japan). The refractive index is a ratio of the velocity of light in air to the velocity of light in solution, which is directly proportional to the number of dissolved solids in urine.

    Urinary dipstick (Siemens, Marburg, Germany) was applied to the first thaw of the urine samples either by dipping in the residual urine volume after aliquoting or by dropping urine on the dipstick to screen for signs of infections in the urine and to measure leukocytes, nitrite, proteins, glucose, and blood presence in the urine.
