Objective To evaluate the significance of conductivity examined by UF-100 urine sediment automated analyzer in determination of renal function of concentration and dilution.
Methods The conductivities of 140 random urine samples and 23 urine samples from a patient with diabetes insipidus was examined by UF-100 urine sediment automated analyzer,and the osmotic pressure of these urine samples was examined by micro-cryoscopic osmometer.
