1.1 Current evidence on the safety and efficacy of angioplasty and stenting to treat peripheral arterial disease causing refractory erectile dysfunction is inadequate in quantity and quality. Therefore, this procedure should only be used in the context of research.
1.2 Further research should provide clear details of patient selection. Efficacy outcomes should include procedural success (as measured by arterial imaging and blood‑flow measurement), validated scoring systems of erectile dysfunction, and the duration of treatment effect. All complications should be reported. NICE may update the guidance on publication of further evidence.
