Not Applicable
Recruiting
Conditions
Erectile Dysfunction
Interventions
Drug: PDE5 inhibitor (tadalafil)
Combination Product: PDE5 inhibitor (tadalafil) and BTL-6000 fSWT
Registration Number
NCT05823506
Lead Sponsor
Saint Petersburg State University, Russia
Brief Summary

The goal of this trial is that using tadalafil plus low-intensity extracorporeal shockwave therapy (li-ESWT) is more effective than using tadalafil alone in improving erection rigidity and sexual function. The efficacy of the combination of li-ESWT and tadalafil has been confirmed by a number of studies, including in patients after radical prostatectomy. However, this method is still not a "first-line" method in young primary patients and its benefits in combination with drugs for these patients are not obvious.

The investigators assume that the combination of tadalafil plus low-intensity extracorporeal shockwave therapy (li-ESWT) will improve the subjective state of patients assessed by points of validated questionnaires and Number of successful intercourse per week.

Detailed Description

The aim of the study is to test the hypothesis that using tadalafil plus shockwave in primary patient with ED treatment in more effective in improving erection rigidity and sexual function, then using tadalafil alone.

Primary Outcome Measures
NameTimeMethod
IIEF-560 days

IIEF-5 (International Index of Erectile Function-5) is validated erectile function assessment questionnaire. The possible scores for the IIEF-5 range from 5 to 25, with lower values representing poorer sexual function.

Secondary Outcome Measures
NameTimeMethod
PGI-I14 days,30 days, 60days.

The Patient Global Imression of Improvement (PGI-I) is a global index that may be used to rate the response of a condition to a therapy. This is a transition scale that is a single question asking the patient to rate their urinary tract condition now, as compared with how it was prior to before beginning treatment on a scale from 1-Very much better to 7-Very much worse.

Likert scale (7-point preferably) satisfaction questionnaire14 days,30 days, 60days.

Likert Scale questions offer a range of answer options from either end of the spectrum for the respondents to choose from, where 1-extremely dissatisfied, 7- extremely satisfied

Therapy comfort survey14 days,30 days, 60days.

Modified scale indicating how comfort patients feel about therapy, where 1is totally uncomfortable, and 7 is very comfortable.
