PURPOSE: Much attention has been focused in recent decades on the effects of erectile dysfunction (ED) secondary to lower urinary tract symptoms (LUTS), potentially underestimating its effects in men without LUTS. This study aimed to compare the prevalence and predictors of ED in men with and without LUTS. MATERIALS AND METHODS: The International Index of Erectile Function questionnaire was administered to 303 patients between January 2014 and June 2016. Within this sample, 147 patients with LUTS (cases) were compared to 156 men without LUTS who were matched for age, level of education, and occupation (controls). RESULTS: The mean age was 66.03±9.64 years and 65.78±8.61 years for the cases and controls, respectively. The prevalence of ED was 64.6% and 73.7% (odds ratio [OR], 1.54; 95% confidence interval [CI], 0.94∼2.51) in the case cohort and controls, respectively (p=0.086). There was no difference in the prevalence of impaired erectile function (p=0.067), impaired orgasmic function (p=0.108), impaired sexual desire (p=0.291), impaired intercourse satisfaction (p=0.869), or impaired overall satisfaction (p=0.191). Multivariate logistic regression analysis showed that being currently employed was a significant predictor of ED both in men with LUTS (OR, 8.08; 95% CI, 1.51∼9.27; p=0.004) and in men without LUTS (OR, 7.00; 95% CI, 1.49∼14.51; p=0.008). Being married only predicted for impaired EF in men without LUTS (OR, 6.34; 95% CI, 1.40∼15.20; p<0.05). CONCLUSIONS: ED was not found to be more prevalent in men with LUTS. Being employed was a predictor of ED in both groups of men, while being married was also a predictor of ED in men without LUTS.

OBJECTIVETo investigate the correlation between subjective assessment from clinician and patients and the objective measurement from active posterior rhinomanometry and acoustic rhinometry.

METHODSClinician and patients' assessment of nasal patency was achieved by visual analogue scale (VAS). Objective measurement included active posterior rhinomanometry and acoustic rhinometry. The mean of clinician's assessment and patients' VAS was compared by using paired-samples t-test. The correlation between unilateral nasal airflow resistance and unilateral nasal airway volume, unilateral minimal cross section area, and also subjective assessment and objective measurement of nasal patency were analysed by using Spearman correlation analysis in total patients.

RESULTSIn total of 316 patients, pre-decongestion and post-decongestion, unilateral nasal airflow resistance and unilateral nasal airway volume, unilateral minimal cross section area had significant negative correlation respectively (P = 0.000). The mean of clinician's assessment and patients' VAS had significant difference (P < 0.001) before and after decongestion. Clinician's assessment had significant positive correlation with patients' VAS, nasal airflow resistance, and significant negative correlation with nasal airway volume, minimal cross section area of nasal cavity before and after decongestion (P = 0.000). Patients' VAS had significant positive correlation with nasal airflow resistance, and significant negative correlation with nasal airway volume, minimal cross section area of nasal cavity before and after decongestion (P = 0.000). The correlation coefficients from clinician's assessment and objective measurements were greater than those from patients VAS and objective measurements.

CONCLUSIONSThe parameter of active posterior rhinomanometry had significant negative correlation with the parameters of acoustic rhinometry. Clinician assessment of nasal patency had significant positive correlation with patients' VAS; both of them had significant correlation with the parameters of rhinomanometry and acoustic rhinometry. Clinician's assessment was more objective and reliable to the parameters of objective measurement than patients' VAS.
