Initial good effect of shock wave for erectile dysfunction is not stable over time
In this recent study, the long-term efficacy of penile low-intensity shock wave treatment was evaluated after an initially successful outcome among 156 patients.
The researchers found that the treatment was immediately successful in 99 patients (63.5%), but during follow-up, a gradual decrease in efficacy was observed. At 2 years, the beneficial effect was maintained in only 53.5% of patients. Over follow-up, the treatment effect was lost in all patients with diabetes who initially had severe erectile dysfunction. However, for patients with milder forms of erectile dysfunction without diabetes, there was a 76% chance that the beneficial effect of low-intensity shock wave treatment would be preserved after 2 years.
Low-intensity shock wave treatment is effective in the short term but treatment efficacy was maintained after 2 years in only half of the patients. In patients with milder forms of erectile dysfunction, without diabetes, the beneficial effect is more likely to be preserved.
