The aim of our study is to evaluate correlation coefficients of surface tension and viscosity with specific gravity, pH and volume in calcium oxalate stone formers and controls. The study was conducted on 50 patients divided into two groups- Group I consist of 25 stone formers and Group II consists of 25 controls i.e. non stone formers. 24-hour urine is collected from each patient and control. The Correlation coefficient of surface tension with specific gravity for group-I & Group-II comes out to be -0.207 & 0.329, surface tension with pH for group-I & Group-II comes out to be 0.151 & -0.184, and surface tension with volume for group-I & Group-II comes out to be 0.158 & 0.122. The Correlation coefficient of Viscosity with specific gravity for group-I & Group-II comes out to be 0.088 & 0.385, Viscosity with pH for group-I & Group-II comes out to be 0.387 & -0.204 and Viscosity with volume for group-I & Group-
II comes out to be 0.166 & -0.202. We can conclude from the values of coefficient coefficients that there exists no correlation between various physical properties of urine studied in relation to renal stone disease.
