The purpose of this study was to assess treatment-seeking behavior and to identify the factors that affect treatment-seeking behavior of men having lower urinary tract symptoms. One hundred thirty-two men working at public institutions or visiting the public institutions were included for this study. Data were collected through a structured questionnaire survey done from October to November, 2016. Data were analyzed using SPSS/WIN 18.0 program. The treatment-seeking behavior was found only in 55.6% (n=79) with lower urinary tract symptoms. The factors that affect treatment-seeking behavior in men with lower urinary tract symptoms significantly were economic status, subjective health status, autonomy, and competence. Results of this study provided fundamental data for developing the program to promote treatment-seeking behavior in men with lower urinary tract symptoms.

This study aimed to investigate variables affecting subjective memory impairment in the elderly with benign prostatic hyperplasia. We used 179 survey data collected from the urology department of two metropolitan general hospitals. The subjects were patients with benign prostatic hyperplasia. T-test, one-way analysis of variance, and $Scheff{\acute{e}}^{\prime}s$ test were performed to identify differences among variables. Pearson's correlation-coefficient and stepwise multiple regression were used to identify variables that affect subjective memory impairment. This study revealed that lower urinary tract symptom and activities of daily living were statistically significant variables, with an explanatory power of 30.0%. The lower urinary tract symptom was due to the benign prostatic hyperplasia increasing the risk of subjective memory impairment. Treatment of the lower urinary tract symptom was delayed because as the elderly got older, they increasingly recognized benign prostatic hyperplasia as a reasonable symptom. Timely intervention and early screening are necessary to prevent lower urinary tract symptom. Finally, programs to reduce the incidence of lower urinary tract symptom and educate nurses to assess, evaluate, perform intervention for subjective memory impairment should be developed.

This study aimed to explore the effects of brain-derived neurotrophic factor (BDNF), produced by engineered immortalized mesenchymal stem cells (imMSC), on lower urinary tract symptoms (LUTS) in a rat model with neurogenic bladder (NB). Forty-eight Sprague-Dawley (SD) rats were randomly divided into the following groups: Sham control, LUTS, LUTS+imMSC (treated with immortalized MSC), and LUTS+BDNF-eMSC (treated with BDNF-expressing MSC) groups. LUTS was induced by a crush injury to the major pelvic ganglion (MPG). Bladder function was tested under anesthesia, and bladder tissue strips were collected thereafter for contractility test and western blot analysis. Western blot results showed that the expression of both Angiopoietin 1 (Ang 1) and platelet-derived growth factor (PDGF) increased with MSC injection. The effect of treatment with BDNF-eMSC on LUTS was also evaluated, and the results were found to be better than those with imMSC (P<0.05). BDNF-eMSC prevented fibrosis in the bladder tissue and significantly reduced caspase-3 levels. In conclusion, high expression of BDNF in vivo resulted in recovery of bladder function and contractility, along with the inhibition of apoptosis in a rat model.

Purpose: The purpose of this study was to find out lower urinary tract symptoms (LUTSs), self-management and quality of life (QOL) in middle aged men and to investigate how these factors are correlated with one another. Methods: The participants in this study were 217 men in G City. Data were collected using a questionnaire from October 23 to November 11, 2009. LUTSs were measured by IPSS, self-management by a self-management Likert scale, and QOL by the Korean-version WHOQOL-BREF. The collected data were analyzed through chi-square test, one-way ANOVA, and Pearson's correlation coefficient. Results: LUTS categories divided according to severity were none (10%), mild (57%), moderate (28%), and severe (5%). The mean score of self-management was 3.14 and that of QOL was 3.27. Self-management and QOL were significantly different according to LUTS. LUTS was negatively correlated with self-management and QOL. Self-management was positively correlated with QOL. Conclusion: In order to develop nursing interventions for middle aged men, comprehensive understanding of LUTS is needed.

Purpose: This study was performed to investigate the effects of lower urinary tract symptoms on depression and quality of life among women in urban areas. Methods: The participants in this study were 306 women in P city. Data were collected using a questionnaire from May 1 to June 6, 2008. Lower urinary tract symptoms (LUTS) were measured with BFLUTS-SF and categorized into voiding, filling and incontinence. The data were analyzed through t-test, one-way ANOVA, Fisher exact test, and multiple regression. Results: Age, filling and incontinence, and all of the subcategories of LUTS explained 16% of variance in depression. Older women, LUTS with incontinence, filling and incontinence, and all the problems including filling, voiding and incontinence lowered the quality of life. Conclusion: In order to develop nursing interventions for women with urinary tract symptoms, comprehensive understanding of LUTS is needed.

Purpose: The purpose of this study was to find out lower urinary tract symptoms, daily life inconvenience, and sleep quality in elderly community woman. Methods: Participants were 140 elderly women. Data collection was conducted from September 1 to October 30, 2017. Data were analyzed using descriptive statistics and t-test with the SPSS program. Results: The rate of urge incontinence was 25.0%, stress incontinence 36.4%, unexplained incontinence 15.7%, and nocturnal incontinence 9.3%. Those participants with urge incontinence presented significantly higher daily life inconvenience scores; urge incontinence, stress incontinence, and unexplained incontinence were significantly associated with lower sleep quality scores. Furthermore, frequent urination, nocturia, and incomplete emptying were significantly higher daily life inconvenience scores; and frequent urination, nocturia, hesitancy, straining, intermittent stream, burning, incomplete emptying, bladder pain, and abnormal strength of stream were significantly related to lower sleep quality scores. Conclusion: It is necessary to develop intervention strategies considering incontinence and urination symptoms to reduce daily life inconvenience caused by lower urinary tract symptoms and improve sleep quality in elderly women.

Purpose: This study aimed to identify the prevalence of lower urinary tract symptoms (LUTS), evaluate factors affecting LUTS among community-dwelling older adults, and provide basic data for a community-based LUTS management program. Methods: A community-based cross-sectional study was conducted from April to November 2010 by using a structured questionnaire. Participants were 157 individuals recruited from 5 community senior centers. Results: The mean LUTS score of the older adults was 9.4 (International Prostate Symptom Score range 0-35). For each LUTS (range 0-5), nocturia was the highest (2.3). Of all older adults, 24.8% had experienced urinary incontinence more than once a month during the past 6 months. Urinary incontinence was found to be an important factor associated with LUTS. Conclusion: A community-based management program for both LUTS and urinary incontinence in community-dwelling older adults should be implemented.

Purpose: The purpose of this study was to investigate the degree of LUTS (Lower Urinary Tract Symptoms) and factors affecting LUTS in patients with prostate cancer. Methods: Fifty-four patients with prostate cancer participated and they completed a structured questionnaire at a hospital in Seoul. The LUTS level was measured by using the International prostate symptom score (1992) and the data were analyzed by Wilcoxon rank sum test and Kurskal-Wallis test. Results: Most subjects obtained a higher than moderate LUTS score. The participants who had a lower perceived health status and did not drink alcohol were more likely to had a lower LUTS score than other patients who had higher perceived health status and drink alcohol. In addition, eye diseases were significantly associated with the LUTS score. In LUTS, all the patients received higher IPSS-QOL (International prostate symptom score quality of life) and frequency, nocturia. Conclusion: For proper nursing care related to LUTS, nurses should focus on the factors identified when performing nursing assessments and should develop nursing intervention programs for symptoms management.

Purpose: The purpose of this study was to analyze the relationship between lower urinary tract symptoms and urodynamic parameters to investigate the characteristics of mixed urinary incontinence (MUI) and stress urinary incontinence (SUI). Methods: The subjects were 318 women with MUI and 128 women with SUI. Data were collected retrospectively from electronic medical records including Bristol Female Lower Urinary Tract Symptoms-Scored Form (BFLUTS-SF), Incontinence Quality of Life Instrument (I-QOL), voiding diaries, and urodynamic parameters. Results: Compared with the SUI group, the MUI group was older and showed lower I-QOL and more severe urinary tract symptoms. The MUI group had more urinary frequency, more nocturia, and a higher urgency score than the SUI group. In the correlation analysis, the greatest difference between the two groups was that urgency was associated with Qmax, maximal cystometric capacity, and detrusor overactivity only in the MUI group (r = -.175, p= .004; r = -.281, p< .001; r= .232, p< .001, respectively). Conclusion: As a result of this study, we propose that a customized management program that emphasizes the control of urgency for the MUI group, and one that effectively strengthens the weak pelvic floor for the SUI group.

Purpose: This study was performed to identify lower urinary tract symptoms (LUTS), and to evaluate the factors affecting LUTS in patients with type 2 diabetes mellitus (T2DM). Methods: The cross sectional study was used with a structured questionnaire to collect data through interviews with 181 T2DM patients and their clinical data from a university hospital diabetes clinic from October 2010 to April 2012. LUTS were measured using the International Prostate Symptom Score (IPSS), depression using the Center for Epidemiologic Studies Depression Scale (CES-D), and glycosylated hemoglobin (HbA1c) from the clinical data. Results: Of all patients with T2DM, the mean IPSS of LUTS was $9.34{\pm}6.86$. Concerning the reported severity of LUTS, 53.6% of the subjects were in the moderate and severe group. In each symptom score of LUTS (range 0-5), nocturia was the highest 2.04, weak stream 1.62, and frequency 1.45. LUTS was significantly predicted by HbA1c and depression, and 14.3% of the variance in LUTS was explained. Conclusion: HbA1c and depression were found to be very important factors associated with LUTS in T2DM patients.
