International Prostate Symptom Score and Quality of Life Index for Lower Urinary Tract Symptoms Are Associated with Aging Males Symptoms Rating Scale for Late-Onset Hypogonadism Symptoms.

purposeAlthough patients with late-onset hypogonadism (LOH) often experience lower urinary tract symptoms (LUTS), LUTS are not generally included in LOH symptoms. No study has examined the direct relation of the Aging Males Symptoms rating scale (AMS) and the International Prostate Symptom Score (IPSS) with the quality of life (QOL) index. We analyzed the relation between the IPSS and QOL index and various factors including the AMS in patients with LOH syndromes. MATERIALS AND

methodsThis study comprised 1,688 men with LOH symptoms who visited our hospital or affiliated clinic. Factors associated with the IPSS were assessed in terms of age, scores of several questionnaires including the AMS, endocrinological variables, and serum concentration of PSA. Among these same factors, those associated with the QOL index were also evaluated. Finally, the same analyses were repeated in 187 patients with low serum testosterone concentration (<3.0 ng/mL).

resultsIn a multivariate analysis using the significant items from the univariate analysis, AMS, age, and Erection Hardness Score correlated significantly with the IPSS. A trend analysis using items other than the AMS as adjustment factors also confirmed the relationship between an increase in QOL index and an increase in AMS. Similar results were obtained in the analysis of patients with low serum testosterone concentration.

conclusionsWe revealed that the relation of IPSS with the QOL index for LUTS is closely associated with the AMS for LOH, regardless of testosterone level. When patients complain of LOH symptoms, a careful, detailed inquiry into LUTS is required.
