Purpose: Oral phosphodiesterase type 5 inhibitors (PDE5Is) is the most popular treatment modality for erectile dysfunction (ED). We investigate the influence of low intensity shockwave therapy (LiESWT) on patients initiating PDE5I therapy.
Materials and Methods: A total of 42 volunteer ED patients in a single hospital are enrolled in the study. They are randomly assigned into two groups: Group A take Tadalafil 5mg per day for 12 weeks, and one LiESWT session per week for the first 6 weeks. Group B take Tadalafil 5mg per day for 12 weeks, and one LiESWT session per week for the last 6 weeks. Study International Index of Erectile Function questionnaire (IIEF), Ankle-brachial Pressure Index (ABI), Erectile Hardness Scale (EHS) are recorded and compared between two groups.
Results: The study is still ongoing. According to present response from the subjects, group A (PDE5I + LiESWT) is better than group B (PDE5I alone, then add-on LiESWT later).
Conclusions: Concurrent PDE5I therapy and LiESWT is probably more effective than PDE5I therapy alone.
