NCT05823506

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.

Outcome Measures

Primary Outcomes (1)

  • IIEF-5

    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.

    60 days

Secondary Outcomes (4)

  • PGI-I

    14 days,30 days, 60days.

  • Likert scale (7-point preferably) satisfaction questionnaire

    14 days,30 days, 60days.

  • Therapy comfort survey

    14 days,30 days, 60days.

  • Number of successful intercourse per week

    14 days,30 days, 60days.

Study Arms (2)

Medication group

ACTIVE COMPARATOR

PDE5 inhibitor tadalafil in dosage 5 mg daily by 1 month

Drug: PDE5 inhibitor (tadalafil)

Combination group

EXPERIMENTAL

PDE5 inhibitor tadalafil in dosage 5 mg daily by 1 month plus Device BTL-6000 fSWT: 6 sessions with EFD 0,09 mJ/mm2 by 5000 impulses per session in 5 points in corpora cavernosa penis

Combination Product: PDE5 inhibitor (tadalafil) and BTL-6000 fSWTDrug: PDE5 inhibitor (tadalafil)

Interventions

The mechanism of low-intensity shockwave therapy in patients with ED based on the effect on the endothelium of the cavernous arteries, the release of NO and the enhancement of vascularization due to release of angiogenic factors.

Combination group

Tadalafil improves erectile function by inhibiting PDE5 isoenzyme, thereby blocking cGMP degradation. As a result, the PDE5 inhibitors act synergistically with NO to markedly increase the levels of cGMP, which in the presence of sexual stimulation, lead to an erection. In the absence of sexual stimulation, NO is not released locally and the PDE5 inhibitors do not affect the penis. Thus, sexual stimulation is needed to initiate the erectile mechanism for the PDE5 inhibitors to take effect.
