Variations of Biochemical and Cellular Urine Parameters among a Healthy Lebanese Group

Objectives: Urine analysis, a simple and inexpensive test, is the cornerstone in the evaluation of the kidney function and may reflect some pathophysiologies. Materials: A cross sectional study was carried out in Lebanese University of Lebanon. One hundred asymptomatic students and stuff were enrolled in this study. Urine samples were obtained from students and stuff and were tested by dipstick method and trypan blue for urine cell count. Results: Among all the samples, leukocyturia and hematuria were the most common abnormalities found with a prevalence of 39% and 24% respectively, followed by proteinuria (13%), nitrituria (8%) and glycosuria (8%). Urinary abnormalities were more common in females than in males. Number of living urine cells was associated to the presence of glucose, proteins and leucocytes in urine (p=0.001, p=0.049 and p=0.027 respectively). Urine viable cells were also significantly correlated with the gender (p=0.000), alcohol and theine consumption (p=0.023, p=0.034 respectively) and smoking status (p=0.003). Conclusion: Asymptomatic urinary abnormalities might be detected by urine screening. Our results confirm that gender and environment factors might affect urine composition.
