Brief summary

Researchers are evaluating the efficacy of low intensity shockwave therapy (LISWT) via MoreNova in the treatment of erectile dysfunction (ED).

Detailed description

ED is broadly defined as the inability to achieve or maintain an erection sufficient for sexual intercourse or activity. Current treatment for ED consists of oral medications, intracavernosal injections and surgically placed penile prosthetics. In the literature this has been described as a Stepwise Approach, offering therapy beginning with the least invasive treatment option. The goal of LISWT is to restore natural erections and / or improve responses to oral medications (first line therapy). LISWT for ED is under evaluation in the USA. The European Association of Urology Guidelines on ED were recently updated to include LISWT for men with mild to moderate ED. The energy/pulse used in this application is approximately 10% of the energy used for disintegrating kidney stones; no serious side effects have been reported. Shock wave therapy for diabetic ulcers has recently been approved by the FDA.

MeasureTime frameDescription
Change in Right Resistive IndexTreatment 6 Final Shockwave treatment (pre-procedure, intra-procedure, post procedure) approximately 1 hourResistive Index (RI) is a measure of resistance to blood flow within the right penile arteries. Measured using a Color Duplex Doppler Ultrasound (CDDU) measured in cm/second Elevated values are associated with a poorer prognosis. Lower values are associated with a better prognosis.
Change in Right Peak Systolic VelocityTreatment 6 Final Shockwave treatment (pre-procedure, intra-procedure, post procedure) approximately 1 hourPeak systolic velocity (PSV): The maximum velocity of blood flow during erection. Measured using a Color Duplex Doppler Ultrasound (CDDU) measured in cm/second A PSV higher than 35 cm/sec is regarded as normal, a 25-35 cm/sec may indicate moderate-to-mean arterial damage, and a PSV lower than 25 may indicate the presence of severe arteriopathy.
Change in Right Diastolic VelocityTreatment 6 Final Shockwave treatment (pre-procedure, intra-procedure, post procedure) approximately 1 hourDiastolic Velocity (DV) represents the velocity of right-side blood flow during the resting phase of the cardiac cycle. A DV less than 5 cm/s is considered normal (better). A DV less considered abnormal (worse). Measured using a Color Duplex Doppler Ultrasound (CDDU) measured in cm/second
Erection Hardness Score (EHS)Treatment 6 Final Shockwave treatment (pre-procedure, intra-procedure, post procedure) approximately 1 hourMeasured using a self-reported Erection Hardness Score (EHS) scale options from 0 (minimum) to 4 (maximum). 0- Penis does not enlarge, 1- Penis is larger but not hard, 2- Penis is hard but not hard enough for penetration, 3- Penis is hard enough for penetration but not completely hard, or 4-Penis is completely hard and fully rigid. A lower score indicates a worse outcome. A higher score indicates a better outcome.
International Index of Erectile Function (IIEF - EF) QuestionnaireTreatment 6 Final Shockwave treatment (pre-procedure, intra-procedure, post procedure) approximately 1 hourMeasured using a self-reported International Index of Erectile Function questionnaire (IIEF - EF) consisting of 6 questions regarding the participants erectile function for the past 4 weeks. The questionnaire utilizes a scale of 0 (minimum) to 5 (maximum). A lower score indicates a worse outcome. A higher score indicates a better outcome. Questions 1-2 scale: 0=No sexual activity, 1= Almost never/never, 2= A few times (much less than half the time),3= Sometimes (about half the time), 4= Most times (much more than half the time),5= Almost always/always Questions 3-4 scale: 0=Did not attempt, 1=Almost never/never, 2= A few times (much less than half the time), 3= Sometimes (about half the time), 4= Most times (much more than half the time), 5= Almost always/always Question 5 scale:0=Did not attempt intercourse,1= Extremely difficult, 2=Very Difficult, 3=Difficult, 4= Slightly Difficult, 5= No Difficult Question 6 scale: 1= Very low, 2=Low, 3=Moderate, 4=High, 5= Very high
Sexual Encounter Profile (SEP) QuestionnaireTreatment 6 Final Shockwave treatment (pre-procedure, intra-procedure, post procedure) approximately 1 hourMeasured using a self-reported Sexual Encounter Profile (SEP) Questionnaire consisting of 2 questions. The questionnaire utilized Yes or No response options. No, indicates a worse outcome. Yes, indicates a better outcome.
Global Assessment QuestionnaireTreatment 6 Final Shockwave treatment (pre-procedure, intra-procedure, post procedure) approximately 1 hourMeasured using a self-reported Global Assessment Questionnaire consisting of 2 questions. The questionnaire utilized Yes or No response options. No, indicates a worse outcome. Yes, indicates a better outcome.
Change in Left Peak Systolic VelocityTreatment 6 Final Shockwave treatment (pre-procedure, intra-procedure, post procedure) approximately 1 hourMeasured using a Color Duplex Doppler Ultrasound (CDDU) measured in cm/second A Peak Systolic Velocity of 25-35 cm/s or higher is considered normal. This reflects the maximum velocity of blood flow during erection.
Change in Left Diastolic VelocityTreatment 6 Final Shockwave treatment (pre-procedure, intra-procedure, post procedure) approximately 1 hourDiastolic Velocity (DV) represents the velocity of left-side blood flow during the resting phase of the cardiac cycle. A DV less than 5 cm/s is considered normal (better). A DV less considered abnormal (worse). Measured using a Color Duplex Doppler Ultrasound (CDDU) measured in cm/second
Left Resistive IndexTreatment 6 Final Shockwave treatment (pre-procedure, intra-procedure, post procedure) approximately 1 hourResistive Index (RI) is a measure of resistance to blood flow within the left penile arteries.
