Audiovisual sexual stimulation (AVSS) has been suggested to help improving PDU performance.<\/jats:p><\/jats:sec><jats:sec><jats:title>Aim<\/jats:title><jats:p>To evaluate the use of AVSS as a tool to improve diagnostic accuracy of PDU studies.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A total of 40 men (mean age: 61.8 \u00b1 10.2 years) with ED were enrolled. PDU sessions were performed in a randomized fashion as follows: session A under intracavernous injection (ICI) alone and session B under ICI and AVSS with 7-day interval between sessions. Peak systolic velocity (PSV), end-diastolic velocity (EDV), and resistive index (RI) were measured 5, 10, 15, and 20 minutes after ICI.<\/jats:p><\/jats:sec><jats:sec><jats:title>Main Outcome Measure<\/jats:title><jats:p>Comparisons between PSV, EDV, and RI values were performed with and without AVSS. Univariable and multivariable analyses including clinical and demographic parameters were performed to evaluate predictors of an abnormal PDU.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>23 patients performed the first session without AVSS, and 17 performed the first session with AVSS. EDV and RI were better in AVSS session (p\u00a0= 0.022 and 0.019). PSV was not influenced by AVSS (p\u00a0= 0.768). The proportion of patients whose diagnosis was changed because of the AVSS was 4 of 40 (10.0%, 95% confidence interval [CI]: 2.8\u201323.7%). Of 12 patients with venous leak observed on the PDU without AVSS, 3 turned into normal after AVSS (25.0%, 95% CI: 5.5\u201357.2%). Of 4 men with arterial insufficiency observed on the PDU on ICI alone, 1 became normal after AVSS (25.0%, 95% CI: 0.6\u201380.6%). International Index of Erectile Function-5 scores were lower in patients with abnormal PDU (6.3 \u00b1 3.3 vs 12.0 \u00b1 5.8, p=0.003). On multivariable analysis, DM and International Index of Erectile Function-5 scores were the only independent predictors of abnormal PDU studies.<\/jats:p><\/jats:sec><jats:sec><jats:title>Clinical Implications<\/jats:title><jats:p>False diagnoses of venous leak during PDU with ICI could be a result of an increased adrenergic discharge during the examination. Routine AVSS may be helpful to avoid error in diagnosis.<\/jats:p><\/jats:sec><jats:sec><jats:title>Strength &amp; Limitations<\/jats:title><jats:p>The study has randomized the use of AVSS in different session orders. Only one previously published study has used this strategy to control the accommodation effect in repeat studies, a common source of bias in the PDU literature. The main limitation is the absence of a rigidity assessment and a redosing protocol.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Adding AVSS during PDU improves ICI
