Baseline Lower Urinary Tract Symptoms and Sexual Dysfunction in Men with Newly Diagnosed Localized Prostate Cancer

Abstract

We evaluated baseline lower urinary tract symptoms (LUTS) and sexual dysfunction in patients with newly diagnosed localized prostate cancer. Data were obtained from a cohort registry of patients with localized prostate cancer scheduled for radical prostatectomy. Before surgery, patients completed a 3-day voiding diary; International Prostate Symptom Score (IPSS), International Index of Erectile Function-5 (IIEF-5), and Expanded Prostate Cancer Index Composite (EPIC) questionnaires; and a urodynamic study. Data were analyzed according to benign prostatic hyperplasia treatment status and age group. In total, 380 patients (median age, 67 years) were enrolled in this study. On the IPSS, 10.8% of patients had severe symptoms. On the IIEF-5, 8.7% of patients did not have erectile dysfunction and 52.9% had moderate-to-severe erectile dysfunction. On the EPIC, 3% of patients indicated that they did not have urinary control and only 13% responded that their erectile function was good or very good. The mean IPSS and IIEF-5 scores showed significant differences among age groups. Thus, patients with localized prostate cancer show various LUTS and sexual dysfunction at baseline, and these symptoms worsened with increased age.
