Overview
abstract
BACKGROUND: Intracavernosal injection therapy (ICI) is an effective intervention used to treat erectile dysfunction (ED). It has been proposed that caution should be exercised when prescribing ICI to patients currently taking anticoagulants (AC) due to the theoretical increased risk of bleeding, however, there is limited literature describing complication rates of actively anticoagulated patients utilizing ICI. AIM: We sought to determine whether there was a difference in bleeding and other complications in a cohort of patients using ICI therapy with or without concurrent AC use. METHODS: We reviewed our institutional electronic health record and identified 168 patients who were seen in our clinic from January to August 2020 who had either currently or previously utilized ICI therapy for ED treatment. These patients were surveyed regarding their ICI therapy as well as given the erectile dysfunction inventory for treatment satisfaction questionnaire. Data from 85 patients was obtained; 43 concurrently using AC during ICI therapy and 42 with no AC use. Fisher's exact test for categorical variables and a 2-tailed t-test were used with P < .05 considered to be significant. OUTCOME: Documented bleeding events (eg, bruising, hematoma), complications, and mean erectile dysfunction inventory for treatment satisfaction scores were compared between the 2 groups. RESULTS: There were more absolute bleeding complications in the AC group vs the no AC group, with 3 of 43 AC patients (7%, 95% confidence interval: 2.4-18.6) and 0/42 no AC patients (0%, 95% confidence interval: 0-8.4) experiencing some type of bleeding complication on ICI. However, there was no statistically significant difference found in overall or stratified documented bleeding events and complications between the 2 groups. CLINICAL IMPLICATIONS: Patients with concurrent AC usage on ICI therapy reported a higher rate of absolute bleeding complications than our non-AC group. STRENGTHS AND LIMITATIONS: The strength of this study is addressing question of safety of ICI therapy in patients with concurrent AC usage. Limitations include single-center retrospective study design and underpowered sample size limiting confidence with which conclusions from data should guide future patient counseling regarding ICI risks. CONCLUSION: Findings from a single-center cohort of patients suggest that ICI therapy may be a safe and effective treatment modality for ED in patients with concurrent anticoagulant usage, however, given the higher rate of absolute bleeding events in our AC cohort, future assessment in a higher-powered study is warranted in determining a more accurate estimation of risk or propensity for bleeding complications in patients on AC using ICI therapy.
