Introduction: The numbers of male lower urinary tract symptoms (LUTS) and sexual dysfunction (SD) are increasing worldwide including Malaysia. Both disorders caused significant effects on quality of life. Most men assume both disorders as age-related problem and opt to go untreated. Exploring the prevalence of both disorders and their effects on males’ quality of life in Sarawak by nurses is highly relevant. There has to be a significant change in the way these two health problems are assessed and managed by the nurses often with little or no medical participation. This study was aimed to determine the occurrence of LUTS and SD in men, and their effects on quality of life in Sarawak. Methods: A cross-sectional, survey-based study was used involving 162 male outpatients of age 40 years, recruited at outpatient clinics in Sarawak General Hospital. Questionnaires on International Prostate Symptoms Score; Danish Prostatic Symptoms Score-Sex and International Index for Erectile Function; and quality of life - Short Form-36 were given to eligible participants. Results: Results revealed that the occurrence of moderate to severe LUTS among male respondents attending non-urological clinics were14.8% and most common in 60-69 years old males. 84.6% of them experienced nocturia. 47.83% had severe erectile dysfunction and most common in 70-79 years old males. LUTS were also positively associated with erectile dysfunction. However, the findings on quality of life showed that both diseases were negatively associated with physical and mental composite summaries in Short Form-36. Con- clusions: The results implied that prevalence of both disorders and their effects on men’s quality of life is significant and have impacts on clinical practice. Contributing factors to male LUTS and SD were identified and need to be addressed accordingly to minimise the occurrence and complications of both disorders to men.
