Worse urinary incontinence appears to be associated with worse sexual function in patients presenting with lower urinary tract symptoms (LUTS), according to a study presented at the 2021 American Urological Association Annual Meeting.1
“Patients with low urinary tract symptoms (LUTS) frequently complain [of] sexual dysfunction and sometimes even urinary incontinence (UI),” the authors wrote in their abstract.
For the cross-sectional study, the investigators retrospectively retrieved data from 938 patients older than 18 years of age seeking treatment for self-reported LUTS. Patients had to have a minimum International Prostate Symptom Score (IPSS) of at least 1 to be included. The cohort was stratified into categories as follows: no urinary incontinence (UI): International Consultation on Incontinence Questionnaire-Urinary Incontinence-Short Form (ICIQ-UI-SF) = 0; mild UI: ICIQ-UI-SF = 1-7; moderate UI: ICIQ-UI-SF = 8-13; and severe UI: ICIQ-UI-SF = 14-21. The Spearman correlation test was used to evaluate correlation between ICIQ-UI-SF and International Index of Erectile Function (IIEF) domain scores. Linear regression analysis tested putative risk factors associated with increased ICIQ-UI-SF scores.
Of the 938 patients studied, 589 (63%) had no UI, 247 (25%) had mild UI, 76 (8%) had moderate UI, and 36 (4%) had severe UI.
Although no substantial differences were found in total prostate-specific antigen levels and uroflowmetry levels among the groups, prostate volume, IPSS, and overactive bladder-questionnaire score were all higher as UI increased (P ≤ .03 for all).
The investigators also found a negative correlation between IIEF-Total (rho = –0.12; P < .001), IIEF-Erectile Function (rho = –0.15; P < .001), IIEF-Intercourse Satisfaction (rho = –0.1; P = .004), and IIEF-Overall Satisfaction scores (rho = –0.12; P < .001) and ICIQ-UI-SF scores. In addition, they reported that higher body mass index (Coeff 0.12; 95% CCI: .03-0.32, P = .011), diabetes (Coeff 1.76; 95% CI: .035-3.18, P = .015), and presence of comorbidities (Coeff 0.9; 95% CI: 0.06-0.174; P = .035) were all associated with higher ICIQ-UI-SF scores.
“In conclusion, we found that in patients presenting with LUTS, there is an association between urinary incontinence and [worse] sexual function,” said study author Giuseppe Fallara, MD, urology resident at San Raffaele Scientific Institute, Milan Italy, who worked on the study with Andrea Salonia, MD, and colleagues.
