No significant differences in age (p = 0.1), comorbidities (all p > 0.05), CRP (p = 0.4), WBC (p = 0.9), residual urine (p = 0.9), fever at admission (p = 0.4), LOS (p = 0.3), abscess operation during inpatient treatment (p = 0.3) nor recurrence of epididymitis (p = 0.3) were recorded. This evidence concerns the gene CRP and epididymitis.
