The relation between symptom scoring (Boyarsky symptom severity score) and their outcome of the treatments for the patients with prostatodynia were evaluated. The patients with poor outcome were examined by uroflowmetry. Twenty-two of the 236 patients with prostadodynia complained of severe symptoms of voiding (score over 7) at the first presentation. Since those patients fell into the poor outcome category by the conventional treatments (p < 0.01), there may be some possibility that this group suffered from conditions other than prostatitis or other unknown causes. The 9 patients with severe voiding symptoms and poor outcome indicated abnormal uroflowmetric results such as abnormal peak flows in 8 patients and abnormal uroflow curves in all 9 patients. This strongly suggests that these patients have lower urinary tract dysfunctions. In conclusion, measurement of Boyarsky symptom severity scores and uroflowmentry is a useful screening method for the patients with prostatodynia with severe voiding symptoms to rule out the lower urinary tract dysfunctions.
