Prostate Dimensions and Their Impact on LUTS and Erectile Function: Is Length the Missing Link?

Area of Science:

• Urology
• Andrology
• Gerontology

Background:

• Prostate health significantly impacts male quality of life, affecting urinary and sexual functions.
• Age-related changes in prostate volume and associated symptoms are common in aging men.
• Understanding correlations between prostate dimensions, lower urinary tract symptoms (LUTS), and erectile function (IIEF) is crucial for patient management.

Purpose of the Study:

• To investigate the relationship between prostate volume, dimensions (width, height, length), LUTS, and IIEF.
• To assess the influence of risk factors (hypertension, diabetes, cardiovascular disease, smoking, alcohol, PSA) on LUTS and IIEF.
• To determine which prostate dimensions correlate with LUTS and sexual function.

Main Methods:

• Retrospective multicenter study of 943 male patients over 40.
• Evaluation of LUTS using IPSS and QoL questionnaires.
• Assessment of sexual function with IIEF-15, PSA levels, and prostate dimensions via ultrasound.

Main Results:

• Prostate-Specific Antigen (PSA), IPSS, and prostate volume increased with age, while IIEF declined.
• IPSS positively correlated with prostate volume and age; IIEF negatively correlated with prostate volume and age.
• Prostate length showed a significant correlation with IPSS (p=0.011), while width and length correlated with IIEF.
• Cardiovascular disease significantly impacted IPSS and IIEF in patients with moderate to severe symptoms.

Conclusions:

• Prostate volume, IPSS, and IIEF are correlated, with prostate length being a significant factor for both.
• PSA levels increase with age, and prostate volume impacts urinary and sexual function.
• Hypertension, diabetes, smoking, and alcohol consumption did not significantly affect LUTS or erectile function, unlike cardiovascular disease.
