Clinical Trial Summary

The purpose of this project is to verify the relationship between low intensity shock wave treatment (LI-SWT) and increased scores in self-assessment regarding to erectile function (ED) and sexual intercourse, in patients, who has undergone a radical prostatectomy (RP). The data will be obtained from patients using international accepted sexual questionnaires prior to the LI-SWT and 5, 12 and 24 weeks following treatment.


Clinical Trial Description

Extracorporeal shockwave therapy (ESWT) has been used for many years in different fields. In 1980, the clinical use of extracorporeal shockwave lithotripsy as a treatment for stone disease in the upper urinary tract began and proved effective. Throughout the years, ESWT has been modified for use in other specialties, such as in the treatment of gallstones, sialolithiasis and Peyronie's disease. Animal studies have demonstrated neoangiogenesis in myocardial tissue and skin flaps as well as regeneration of nervous tissue. Gotte et al. found that shock waves can, under suitable conditions, lead to non-catalytic synthesis of physiologically relevant quantities of NO. These pioneering findings corroborate our hypothesis that ED due to RP, can likely be treated by LI-SWT.

It is well known that patients radically operated for prostate cancer subsequently develop erectile dysfunction (ED) and /or urinary incontinence. A meta-analysis from 2009 found that the overall erection recovery rate after prostatectomy were 58%, meaning that a certain amount of patients still suffer from ED in the postoperative lifespan.

The investigators want to investigate in a randomized trial whether LI-ESWT is efficient in ED patients, who has undergone RP, regarding to sexual function. These data will be assessed by changes in outcome of sexual questionnaire regarding to sexual function and erection hardness. This hypothesis has previous been tested in a Danish pilot study. The study design was a prospective cohort study with 16 participants all suffering from ED due to nerve sparing RD. The participants received two series of LI-ESWT per week in a 3-week period. The results indicated a gradual increase in erectile function at the 1 month follow up, evaluated by cross matching the IIEF-15 scores before and after treatment. However, the effect was damped off at the last follow up one year later. The pilot study concluded that more research had to be done in a larger population group.

The study design is decided to be a prospective, blinded, randomized placebo-control follow up design. The total enrol of participants are estimated to be sixty-four divided into a placebo group and an active group.

The participants who meet the inclusions criteria (see section below) will be randomly assigned to either a control group (P) or an active group based (V) on a randomization list.

The treatment sessions will take place at the outpatient clinic of the department of urology L, OUH. The shock wave device used for this study is a duolith® SD1 T-Top from Storz Medical (see fig. 2). The device is set at 0.15 mJ/mm2, 5 Hz, with a total of 3000 impulses, and a total energy of 12.8 J per treatment. LI-ESWT will be performed in six positions on the penis (distal, center and proximal part of each cavernous body) and given by a therapist educated for the purpose. The cap used to prevent LI-SWT in the placebo group will be positioned by the Head of the Department to ensure valid blinding.

Prior to the treatment, the participants will be asked to fulfil questionnaires (EHS, IIEF-15 and DAN-PSS) to assess data on lower urinary tract symptoms, sexual dysfunction and erection hardness. At the first treatment session (baseline function), the investigator reviews the questionnaires in cooperation with the participant to ensure no conflicts and misunderstanding in questions.

There will be a total of 5 treatment sessions during a 5-week period. Shortly after treatment, the participants will be asked to fill in the questionnaires once again. The questionnaires will be mailed to the participants home addresses together with a prepaid return envelope and asked to be reposted at 5th, 12th and 24th week respectively. ;
