The Electrical Conductivity Of 24-H Urine Is Decreased In Patients With Calcium Oxalate Urolithiasis., Kamonchat Boonkam
Chulalongkorn Medical Journal
Background: Electrical conductivity (EC) of urine depends on the ionic substance-to-water ratio. Calcium oxalate (CaOx) is the most common type of urinary stone, and its formation is driven by decreased urine volume, increased lithogenic substances, and decreased stone inhibitory compounds (specifically citrate). Low urinary citrate excretion (hypocitraturia) is a prominent risk factor in Thai urolithiasis patients.
Objective: To measure the urinary EC, urinary calcium, and urine specific gravity in CaOx stone patients compared with non-stone forming (NSF) subjects.
Method: The urinary EC was measured in 24-h urine samples obtained from 42 CaOx stone patients and 121 NSF subjects. Urinary calcium …
