[Incidence of comorbid ED with LUTS and its risk factors in patients with BPH].

Abstract

Objective: To investigate the incidence of comorbid ED with lower urinary tract symptoms (LUTS) and its risk factors in BPH patients.

Methods: Based on inclusion and exclusion criteria, we selected BPH patients visiting the outpatient department of the Second Xiangya Hospital of Central South University from January 2020 to January 2023. We collected the general and clinical data from the patients, including age, height, body weight, abdominal circumference, hip circumference, blood pressure, blood routine, liver function, kidney function, blood lipids and fasting blood glucose, obtained their IPSS, quality of life (QOL) scores, and IIEF-5 scores by questionnaire investigation, and performed data processing and analysis with the SPSS 22.0 software.

Results: The incidence rate of comorbid ED with LUTS in the BPH patients rose with the increase of age, 36.46% in the 45－49-year group, 43.72% in the 50－54-year group, 53.66% in the 55－59-year group, 69.23% in the 60－64-year group, and 78.74% in the 65－70-year group. The lipid accumulation product (LAP), visceral adiposity index (VAI), triglycerides and glucose (TyG), hepatic steatosis index (HSI), body mass index (BMI), waist-to-hip ratio (WHR), waist-to-height ratio (WHtR), triglycerides (TG) and high-density lipoprotein cholesterol (HDL-C) were correlated positively with IPSS scores and negatively with IIEF-5 scores, while LDL-C and total cholesterol (TC) negatively with IPSS scores and positively with IIEF-5 scores.

Conclusion: The incidence of comorbid ED with LUTS in BPH patients increases with age. The risk factors for this comorbidity include hypertension, dyslipidemia, diabetes, BMI, and lifestyle, and the risk of the condition can be effectively assessed by LAP, VAI, TYG, HSI, BMI, WHtR, WHR, TG and HDL-C.
