In case of females the result showed (17.6%) and (5.1%) in cases with and without UTI. Chi square test revealed statistically significant difference in the proportion of prevalence between subjects with and without UTI with (p < 0.01) in males and (p < 0.001) in females. Males had higher incidence of RS than females with a prevalence of (p < 0.0001). The higher occurrence of RS was observed in age group between 21-40 years for both genders.
