ABSTRACT: Low intensity shockwave
(LiSW) treatment is known to improve revascularization. The method has been
evaluated and is used to treat vasculogenic erectile dysfunction (ED). The
present study aimed to demonstrate the efficacy of a linear focused piezoelectric
shockwave device (Richard Wolf/ELvationPiezowave2) to treat patients
with vasculogenic ED using a novel linear shockwave tissue coverage LSTC-ED® technique. A total of 75 patients were treated using the Piezowave2 device and the LSTC-ED® technique. Patients’ erectile function
was evaluated using the modified IIEF-5 (International Index of Erectile
Function) scale at the beginning of treatment and at 1 month post treatment;
patients were additionally questioned using our own Treatment Satisfaction
Questionnaire (TSQ). The study also included a group of 50 patients treated by
placebo; the outcomes of both groups were compared. The average IIEF-5 score of
patients in the treatment group increased from 14.4 at baseline to 18.6 at 1
month post treatment. According to the IIEF-5 scale, treatment was successful
in 81.33% of patients (61/75). According to the Treatment Satisfaction
Questionnaire (answers 1 to 3 of the TSQ), treatment was successful in 77.3% of
patients (58/75). In the placebo group of 50 patients only 5 patients showed an
improvement based on IIEF score, and 8 reported an improvement based on their
answers to the TSQ. No significant adverse effects were observed during
treatment or in the follow-up period. The Piezowave2 device and the LSTC-ED®technique
proved to be suitable and effective to treat erectile dysfunction.
