Background and objectiveThe characteristic symptom of chronic prostatitis (CP) is pain. Patients with CP often complain of lower urinary tract symptoms (LUTS); however, the voiding domain of the Chronic Prostatitis Symptom Index of the National Institutes of Health (NIH-CPSI) is not sufficient to evaluate LUTS. Therefore, we studied the relationship between the International Prostate Symptom Score (IPSS) and NIH-CPSI scores in men.Materials and methodsWe reviewed 870 men who visited our health care center for a general health check-up and completed IPSS and NIH-CPSI questionnaires between January 2014 and January 2019. An NIH-CPSI pain score ≥4 was defined as the presence of a prostatitis-like symptom (Group 1), and an NIHCPSI pain score less than <4 was defined as the absence of a prostatitis-like symptom (Group 2). The relationship between IPSS and NIH-CPSI sub-scores was investigated. The associations between the IPSS total score and NIH-CPSI sub-scores were assessed using multiple linear regression analysis. ResultsThe mean IPSS total, voiding, storage, and quality-of-life (QOL) scores were higher in Group 1 than in Group 2. Group 1 had fewer subjects in the mild group and more in the moderate and severe groups than did Group 2. Among NIH-CPSI sub-scores, pain score showed the highest correlation between IPSS total (r=0.283), voiding (r=0.266), storage (r=0.237), and QOL score (r=0.263). In regression analysis, only the NIH-CPSI pain score was associated with the IPSS total score (B=0.962, p<0.001).ConclusionsThe NIH-CPSI pain score showed a weak but statistically significant correlation with the IPSS, but the NIH-CPSI voiding score did not. This finding suggests that patients with CP-like symptoms need to be surveyed using the IPSS questionnaire. It will also be helpful to screen for comorbidities of benign prostatic hyperplasia and CP.
Purpose: The association of lower urinary tract symptoms (LUTS) and erectile dysfunction has not been investigated comprehensively concerning which LUTS are associated with sexual function. Therefore, we investigated the association of each domain of the International Prostate Symptom Score (IPSS), nocturia, prostate volume, and uroflowmetry with each domain of the International Index of Erectile Function (IIEF)-5. Materials and Methods: The correlation of sexual function and LUTS was investigated in 365 men with benign prostatic hyperplasia. To measure the level of LUTS, the IPSS was calculated; uroflowmetry, residual urine measurement, and transrectal ultrasonography (TRUS) were performed; and the level of erectile dysfunction was assessed by the IIEF-5. Three months after treatment with α-blocker (tamsulosin 0.2 mg/day), IPSS, uroflowmetry, residual urine, nocturia, and IIEF-5 were assessed again to evaluate the effectiveness of treatment. Results: Erectile function deteriorated more in individuals with severe LUTS (IPSS＞20) than in those with mild LUTS (IPSS＜8), and IPSS, age, and nocturia correlated significantly with all IIEF-5 domains. The maximal urine velocity and the average urine velocity on uroflowmetry correlated significantly with all IIEF domains. After the administration of α-blocker for 3 months, the changed rates of the IPSS-obst domain, average uroflow, and quality of life (QoL) correlated significantly with the improvement in the total IIEF-5. Conclusions: Changes in the IPSS-obst domain, QoL, and average uroflow rate correlated significantly with changes in the total IIEF-5. Thus, it is expected that the improvement of obstructive symptoms could effectively
