Santi D, Spaggiari G, Simoni M, Granata AR. Accurate and time‐saving, two‐step intracavernosal injection procedure to diagnose psychological erectile dysfunction. Andrology 2022; 10:852-862. [PMID: 35279959 PMCID: PMC9311207 DOI: 10.1111/andr.13175] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2022] [Revised: 02/28/2022] [Accepted: 03/07/2022] [Indexed: 11/29/2022]
Abstract
Background The recognition of the erectile dysfunction pathogenesis is essential to identify the appropriate erectile dysfunction management. As vascular erectile dysfunction could be a manifestation of a systemic arterial damage, the watershed in the erectile dysfunction diagnostic framework is the discrimination between psychological erectile dysfunction and vascular erectile dysfunction. However, reliable tools to directly diagnose psychological erectile dysfunction are currently lacking. Objective To identify which parameters could predict psychological erectile dysfunction. Moreover, we suggest a new intracavernosal injection procedure to optimize the erectile dysfunction diagnostic workup. Materials and methods A retrospective, real‐world analysis was carried out including all men who underwent intracavernosal injection procedure at the Modena Andrology Unit from 2018 to 2021. A first intracavernosal injection procedure with 5 µg of prostaglandin E‐1 (PGE‐1) was performed. In the absence of a full drug‐induced erection (immediate or delayed), an echo‐color Doppler penile evaluation after administration of PGE‐1 10 µg was conducted, measuring intracavernosal blood flows, to document a possible vascular etiology. Hormonal evaluations were performed. Results Out of 179 enrolled patients, 70.4% showed psychological erectile dysfunction, 21.7% vascular erectile dysfunction, and 7.8% hormonal genesis. Multinomial logistic regression analysis identified absence of cardiovascular disease (p = 0.017), presence of spontaneous morning erections (p = 0.018), and normal penile erections with masturbation (p = 0.035) as predictors of psychological erectile dysfunction. Clinically, normal intracavernosal injection test response was detected in 86 patients and abnormal response in 93 subjects. Among the latter, 54 patients experienced a delayed response. The combination of intracavernosal injection test with late penile erections evaluation was able to diagnose psychological erectile dysfunction (sensitivity 97%, specificity 100%), avoiding unnecessary retesting. Discussion We propose a two‐step intracavernosal injection procedure that allows to recognize psychological erectile dysfunction with a high sensitivity/specificity, saving costs and time, and limiting adverse events. Moreover, the presence of spontaneous morning erections and valid penile erections after masturbation could guide the diagnostic workup, indirectly identifying those patients deserving of a deeper evaluation of vascular health.

Abstract
ResumenEl objetivo del presente artículo es mostrar una serie de alteraciones peneanas que, aunque frecuentes en la consulta de medicina sexual, son minimizadas, la mayoría de las veces por desconocimiento de los terapeutas, aunque para los pacientes que las padecen sean genuinas tragedias personales. Hemos revisado la literatura disponible sobre un grupo de seis patologías venosas especificas del pene que configuran el grupo más representativo. Se incluyen las frecuentes e indolentes venas superficiales tortuosas, los cirsoceles o flebectasias, las fugas venosas dorsales, que suelen ser una patología congénita, las deformantes malformaciones venosas del glande, la desconcertante y enigmática enfermedad de Mondor, y las fístulas arteriovenosas, con su riesgo de priapismo de alto flujo implícito. Todas se consideran alteraciones patológicas que requieren intervenciones menores en su tratamiento, excepto ciertos casos de fugas venosas y de fístulas, cuyo manejo es invasivo, y que, en conjunto, buscan una mejor comprensión de los hallazgos cotidianos en este órgano.

Abstract
BACKGROUND Because it is a superficial structure, the penis is ideally suited to ultrasound imaging. A number of disease processes, including Peyronie's disease, penile fractures and tumors, are clearly visualized with ultrasound. Baseline and dynamic assessment of cavernosal arterial changes after pharmaco-stimulation with alprostadil allows standardized diagnosis of arterial and venogenic causes of erectile dysfunction (ED). OBJECTIVE To illustrate how to correctly perform flaccid and dynamic penile duplex ultrasound (D-PDU) and in which patients to recommend it. MATERIALS/METHODS An extensive search of the literature was carried out on Pubmed with the insertion of the following Medical Subjects Headings (MeSH) terms and keywords "penile color Doppler ultrasound" "peak systolic velocity" "end-diastolic velocity", "acceleration time", "resistance index". EVIDENCE In our experience, arterial erectile dysfunction is identified after standardized intracavernous injection (ICI) of alprostadil (10 mcg) when values of peak systolic velocity (PSV) are <35 cm/s and, in the most severe forms, for values <25 cm/s. Arterial insufficiency can also be identified by increased acceleration time (AT) values (>110 ms) and/or by a lack of visualization of helicine arteries at power Doppler mode along with incomplete achievement of penile rigidity. The veno-occlusive incompetence is determined when end-diastolic velocity (EDV) values are >4.5-5 cm/s or in the case of resistance index (RI) values <0.75. The assessment of additional surrogate markers of endothelial dysfunction, that is, intima-media thickness, mean platelet volume (MPV), endothelial progenitor cells (EPC), endothelial cell specific molecule-1(endocan) are also useful in assessing the patient's cardiovascular risk but are still considered investigational in the interpretation of D-PDU results. CONCLUSION D-PDU scan after ICI with vasoactive drugs is a safe procedure and represents the gold standard for the diagnostics of penile pathologies and should be performed in men with ED not responding to oral conventional therapies and/or in those requiring accurate stratification of cardiovascular risk.

Abstract
AIMS Erectile dysfunction (ED) is a frequent microvascular complication of type 2 diabetes mellitus (T2DM). Hormonal derangements such as hypogonadism and hyperestrogenism are common in T2DM. Our aim was to investigate the relationship between estrogens and ED in diabetic patients. METHODS We performed a retrospective study on 57 patients with T2DM suffering from ED. ED was assessed with the International Index of Erectile Function questionnaire (IIEF-5) and penile color-doppler ultrasound (PCDU). Blood tests included glycated hemoglobin, lipid profile, total testosterone (T), and estradiol (E2). RESULTS E2 was negatively correlated with IIEF-5 score after correction for age, diabetes duration, BMI, HbA1c, LDL- and HDL-cholesterol, T and PSA (r = -0.457, p < 0.01). Patients in the higher E2 quartile, had statistically higher probability of severe ED (61.5%). In the same patients, the PCDU demonstrated a statistically longer Acceleration Time (120.0 ± 24.5, p = 0.048) indicating an impaired arterial flow. CONCLUSIONS In diabetic patients, higher E2 is associated with worse erectile function and impaired cavernous arterial flow. Diabetic patients with high E2 are more prone to severe ED. It could be suggested to include estradiol measurement in the hormonal assessment of ED in patients with T2DM.

Abstract
INTRODUCTION The vascular evaluation of the erectile function through Color Duplex-Doppler Ultrasound (CDDU) of the penis can benefit the therapeutic decision-making process. Unfortunately, there is no standard procedure for CDDU conduction, a fact that results in high result-interpretation variability. OBJECTIVE The aims of this review are to promote greater standardization during CDDU of the penis and discuss the fundamental principles for its accurate conduction. METHODS CDDU is initially conducted with the penis in the flaccid state; the whole penis must be assessed (images at B mode) with a high-frequency linear transducer (7.5-18 MHz). Intracavernous injection of vasodilating agents (prostaglandin E1, papaverine, phentolamine) is performed to induce a rigid erection. Serial measurements at different times should be taken during the CDDU session and penile rigidity must be assessed in each evaluation. RESULTS It is important to monitor the erection response after the vasoactive agent (hardness scale), and scanning during the best-quality erection should be contemplated. Manual self-stimulation, audiovisual sexual stimulation (AVSS), and vasoactive agent re-dosing protocols must be taken into account to reduce the influence of psychogenic factors and to help the patient to get the hardest erection possible. Such measurements contribute to the maximal relaxation of the erectile tissue, so the hemodynamic parameters are not underestimated. CONCLUSIONS CDDU is a relevant specialized tool to assess patients with erectile dysfunction; therefore, this guideline will help to standardize and establish uniformity in its conduction and interpretation, taking into consideration the complexity and heterogeneity of CDDU evaluations of the penis.

A novel method for hemodynamic analysis of penile erection. Int J Impot Res 2020; 34:55-63.

Abstract
Measurement of blood flow velocity through the cavernosal arteries via penile color Doppler ultrasound (PDUS) is the most common objective method for the assessment of erectile function. However, in some clinical cases, this method needs to be augmented via the invasive intracavernosal pressure (ICP) measurement, which is arguably a more direct index for erectile function. The aim of this study is to develop a lumped parameter model (LPM) of the penile circulation mechanism integrated to a pulsatile, patient-specific, bi-ventricular circulation system to estimate ICP values non-invasively. PDUS data obtained from four random patients with erectile dysfunction are used to develop patient-specific LPMs. Cardiac output is estimated from the body surface area. Systemic pressure is obtained by a sphygmomanometer. Through the appropriate parameter set determined by optimization, patient-specific ICP values are predicted with only using PDUS data and validated by pre- and post-papaverine injection cavernosometry measurements. The developed model predicts the ICP with an average error value of 3 mmHg for both phases. Penile size change during erection is predicted with a ~15% error, according to the clinical size measurements. The developed mathematical model has the potential to be used as an effective non-invasive tool in erectile function evaluation, expanding the existing clinical decision parameters significantly.

Abstract
PURPOSE To investigate a possible relation between penile Doppler ultrasound examination (PDUE) parameters and efficacy of chronic therapy with tadalafil (TAD) combined with a protocol of aerobic physical activity (PA) in patients with late onset hypogonadism (LOH). METHODS The study evaluated 30 patients consecutively enrolled with LOH and erectile dysfunction which present contraindication to hormonal replacement therapy for concomitant prostate disease. These patients were subjected to a combined protocol with phosphodiesterase V selective inhibitors (TAD 5 mg daily) and aerobic PA. RESULTS After three months, we observed significant improvements in erectile function [IIEF-5, median (IQR) = 13.0 (7.0-18.0) versus 6.0 (5.0-6.75); p < 0.01] and of the main metabolic [homeostatic model assessment index, median (IQR) = 2.5 (1.62-3.37) versus 3.0 (2.0-3.75); p < 0.01; body mass index, median (IQR) = 27.0 (24.0-28.75) versus 27.5 (24.0-29.5)] and vascular parameters [peak systolic velocity, median (IQR) = 29.5 (24.25-31.0) versus 28.0 (23.0-24.25); acceleration time, median (IQR) = 114 (105.25-134.0) versus 115.0 (106.5-134.0)], assessed by PDUE. CONCLUSION PA in association with phosphodiesterase V inhibitors could compensate the effects of hypogonadism on erectile function and facilitate the clinical response to these drugs even in the absence of adequate serum concentrations of total testosterone.

Abstract
BACKGROUND The low pharmacological response to phosphodiesterase type 5 inhibitors represents an expression of higher endothelial damage in certain categories of patients with erectile dysfunction and high cardiovascular risk. The present study evaluated this objective in type 2 diabetic patients with erectile dysfunction, classified as "non responders" to Sildenafil. METHODS Eighteen "responder" and twelve "non responder" type 2 diabetic patients were evaluated, relatively to different levels of endothelial damage, through the diagnostic use of a new immunophenotype of circulating endothelial progenitor cells (CD45neg/CD34pos/CD144pos) and endothelial microparticles (CD45neg/CD144pos/Annexin Vpos), recently developed and published by our group. RESULTS "Non responder" patients showed a significant higher severity [8.0±3.0 (International Index of Erectile Function-abbreviated version with 5 questions) vs 14.0±3.0] and duration (10.0±2.0 vs 7.0±2.0 years) of erectile dysfunction, higher level of penile arterial insufficiency (peak systolic velocity=13.0±16.0 vs 28.0±26.0cm/s; acceleration time=153±148 vs 125±128 mm/s) and finally a significant higher level of endothelial apoptosis [0.15±0.13 vs 0.05±.0.03% (serum concentrations of endothelial microparticles)] associated with higher serum concentrations of circulating late immunophenotype of endothelial progenitor cells (0.40±0.35 vs 0.12±.0.10%). CONCLUSIONS The results of this study corroborate the clinical value of the low clinical response to phosphodiesterase type 5 inhibitors in the treatment of erectile dysfunction in the patients with high cardiovascular risk profile, such as diabetics. In addition, the markers used in this study confirm their potential application in clinical practice as useful indicators of endothelial alteration. However, in the future we will have to assess a larger number of patients and for a longer period of observation in order to better understand the causal and temporal relations.

Abstract
We have recently demonstrated the diagnostic value of a new immunophenotype of blood endothelial progenitor cells (EPCs=CD45neg/CD34pos/CD144pos) and endothelial microparticles (EMPs=CD45neg/CD144pos/AnnexinVpos) in patients with arterial erectile dysfunction (ED) according to severity of cavernous arterial insufficiency evaluated through penile Doppler. The aim of this study was to evaluate both EPCs and EMPs in patients with arterial ED and metabolic syndrome (MetS), comparing these patients with another group of patients without MetS and ED and a third group with MetS but without ED. For this study 50 patients with arterial ED and MetS were selected (age: 55.0±3.0 years; range: 47-60). A group of age-matched (age: 54.0±2.0 years; range: 44-60) patients without arterial ED and MetS (n=30), and another group of age-matched (age: 57.0±4.0 years; range: 40-62) patients with MetS but without ED (n=20) represented the control groups. EPCs and EMPs were significantly higher in patients compared with other groups (P<0.01). Both EPCs and EMPs correlated positively with the age, body mass index, and score of international index of ED (version five items) and with the following cavernous artery indices: peak systolic velocity, acceleration time and intima-media thickness. Among control groups patients with MetS but without ED showed serum concentrations of EPCs and EMPs significantly higher (P<0.05) compared with patients without MetS and ED. Patients with arterial ED and MetS have higher EPCs and EMPs compared with patients with MetS but without ED and patients without MetS and ED.

Abstract
OBJECTIVE Physical activity (PhA) has proven to be a protective factor for normal erectile function. The aim of this study was to evaluate the effects of a standard protocol of aerobic PhA on quality of erectile dysfunction (ED) in patients with arterial ED. MATERIALS AND METHODS Fifty patients (48-62 years) were selected and underwent to standard protocol of aerobic PhA: 150 min of moderate intensity aerobic activity per week (group A). Twenty patients, matched aged, with vascular ED who did not accept to undergo the standard PhA's protocol, represented the control group. All patients were evaluated, by IIEF-5 questionnaire administration, penile eco color doppler and flow-cytometric analysis for detection of serum concentrations of original immunophenotype endothelial progenitor cells (EPCs) = CD45neg/CD34pos/CD144pos and endothelial microparticles (EMPs) = CD45neg/CD34neg/CD144pos. RESULTS After 3 months, group A showed IIEF 5 score and peak systolic velocity significantly higher (p < 0.05) compared to controls, and significantly lower values (p < 0.05) of acceleration time, in addition serum concentrations of EPCs and EMPs were significantly lower (p < 0.05) in group A compared to controls. CONCLUSIONS PhA improves quality of arterial ED, without other pharmacological approach, probably by reduced endothelial apoptosis. This study characterises the study of endothelial dysfunction by new cell circulating markers.

Abstract
OBJECTIVE Blood endothelial progenitor cells (EPC) and microparticles (EMP) have been proposed as markers of endothelial dysfunction. Aim of this study was to evaluate a new immunophenotype of EPC and EMP in patients with arterial erectile dysfunction (AED) compared to psychogenic erectile dysfunction (PED). MATERIALS AND METHODS One hundred patients (63.2±2.6 yr) with AED were enrolled in this study. Their EPC and EMP concentrations were compared to those of 40 patients with PED (64.2±2.7 yr). EPC (CD45(neg)/CD34(pos)/ CD144(pos)) and EMP (CD45(neg)/CD144(pos)/AnnexinV(pos)) blood concentrations were evaluated by flow cytometry. RESULTS Patients with AED had significantly higher blood pressure, triglycerides, homeostasis model assessment index of insulin resistance, and cavernous artery acceleration time and intima-media thickness than PED; whereas international index of erectile function 5 score, HDL-cholesterol, and cavernous artery peak systolic velocity was lower than PED. Both EPC and EMP were significantly higher in patients with AED compared to patients with PED. CONCLUSIONS Patients with AED showed worse metabolic parameters, cavernous artery parameters, and higher EPC and EMP compared to patients with PED. This suggests that AED is an expression of endothelial dysfunction and that EPC and EMP may be considered predictors of endothelial dysfunction in patients with AED.

Abstract
OBJECTIVE Blood endothelial progenitor cells (EPCs) and endothelial microparticles (EMPs) have been proposed as markers of endothelial dysfunction. Aim of this study was to evaluate an original immunophenotype of EPCs and EMPs in patients with isolated arterial erectile dysfunction (ED) and late onset hypogonadism (LOH) before and after androgen replacement therapy. MATERIALS AND METHODS Fifty patients (50-64 years) with ED and LOH were selected. EPC (CD45(neg)/CD34(pos)/CD144(pos)) and EMP (CD45(neg)/CD34(neg)/CD144(pos)) blood concentrations were evaluated by flow cytometry. Thirty patients received androgen replacement therapy (Tostrex® ProStrakan) for 6 months (group A), other 20 patients not received androgen therapy for the contraindications in their clinical history (group B). RESULTS After 6 months, group B showed IIEF-5 score, peak systolic velocity and acceleration time significantly worse than group A; in addition EPCs and EMPs were significantly higher in group B compared to group A. CONCLUSIONS Patients with isolated arterial ED and LOH not treated with androgen therapy showed worst vascular parameters measured by penile Doppler and higher EPCs and EMPs compared to treated hypogonadal patients, hence, LOH appears to be an additional vascular risk factor, and these markers may be considered as predictors of cavernous artery disease. Finally, androgen therapy improves endothelial dysfunction.

Abstract
BACKGROUND The prevalence of erectile dysfunction (ED) in men with systemic sclerosis (SSc) can be considered a manifestation of endothelium damage. Aim of the study is to investigate ED in SSc patients by color Doppler ultrasound examination and to correlate it with disease severity and digital vascular damage. METHODS In 20 males SSc patients blood flow velocity in the cavernous artery was determined with Duplex ultrasonography. Naifold videocapillaroscopy, Sexual Health Inventory for Men (SHIM) and Medsger Disease Severity Scale (DSS) were performed. Arteriogenic ED was defined by the presence of a reduced peak systolic velocity (PSVs), while diastolic velocity (EDV) and the resistive index (RI) were estimated to evaluate venocclusive dysfunction. SSc patients are classified by capillaroscopic pattern and vascular domain of DSS into two groups: low vascular damage (early or active capillaroscopic pattern and score of vascular domain of DSS≤2) and high vascular damage (late capillaroscopic pattern and score of vascular domain of DSS≥3). RESULTS In all SSc patients a reduction of SHIM is present (mean 13.5±6.3). Patients with less vascular damage have a significantly (p<0.001) higher score of SHIM than patients with greater vascular damage (19.2±2.4 vs 7.9±2.7). No significant difference (p>0.5) between the two groups of vascular damage was found in PSVs. Venocclusive dysfunction was present only (p<0.001) in the group with high vascular damage. CONCLUSION We can assert that there is a relationship between SSc vascular digital damage and ED.

Abstract
Endothelial cells have numerous endocrine functions and contribute to a variety of processes, including penile erection and vasodilation. Endothelial dysfunction is associated with cardiovascular risk factors and has been implicated in the pathogenesis of atherosclerosis and ED. This study reviews endothelial function, in addition to endothelial dysfunction and its role in atherosclerosis and ED. Measurement of endothelial function is reviewed, including catheter-based methods, venous occlusion plethysmography, high-frequency ultrasound, peripheral arterial tonometry, digital pulse amplitude tonometry, digital thermal monitoring, the L-arginine test and measurement of compounds released by endothelial cells. Therapy and medications that improve endothelial function are reviewed. As the scientific community learns more about the importance of the endothelium, it is increasingly important for the clinician to understand endothelial function, dysfunction, measurement of endothelial function and therapies that affect this remarkable cell type.

Abstract
INTRODUCTION In the era of orally active agents, dynamic penile color-duplex ultrasound (D-PCDU) is not considered a necessary first screening for all patients with erectile dysfunction (ED). Various parameters, such as peak systolic flow velocity, end diastolic velocity, resistance index, acceleration time, and degree of arterial dilatation, have been suggested for the diagnosis of vascular ED by D-PCDU. AIM To highlight the clinical utility and evidence-based interpretation of D-PCDU criteria. METHODS Extensive, unsystematic PubMed literature search reviewing relevant data on D-PCDU in the evaluation of male ED. RESULTS The advantage of ultrasound is the minimally invasive nature of the procedure and the ability to screen patients to identify a normal arterial response of cavernous arteries. Men with sexual dysfunctions above 55 years of age and comorbidities are more likely to have multi-organ vascular dysfunction and may necessitate further testing because erectile failure may be the first presenting symptom requiring investigation and treatment even in the absence of cardiovascular risk factors. All patients affected with Peyronie's disease and younger men with persistent ED, a history of pelvic traumas, or fractures of the penile shaft should be offered ultrasonographic penile blood flow studies before referral to surgery or more invasive vascular investigations. CONCLUSIONS In the near future, D-PCDU may be used in preference to patients presenting with or without vascular risk factors, particularly those not responding to first-line orally active drugs and seeking an explanation as to why these agents failed.

Abstract
BACKGROUND Erectile dysfunction is a common and potentially treatable problem. Other than psychological, anatomical and metabolic factors, vasculogenic causes also play an important role in erectile dysfunction. Among the various diagnostic tools available for the diagnosis of vasculogenic causes, colour Doppler sonography is noninvasive, simple and promising. METHODS This preliminary prospective study was conducted on 40 patients with erectile dysfunction, coming from a rural background to a hospital situated in a semi-urban setting. RESULTS It was found that a cut-off value of 10 cm/second for peak systolic velocity in flaccid penis had the best accuracy among three chosen cut-off values, i.e. 5, 10, 15 cm/second, for detecting arterial insufficiency with sensitivity of 94.1%, specificity of 93.6%, negative predictive value of 98% and positive predictive value of 80%. CONCLUSION Doppler sonography may be used as a good predictor of clinical response to intracavernosal injection of a vasodilating pharmacological agent.

Abstract
The aim of this study was to investigate the relationship between penile color Doppler sonography (CDS) findings and sonographic endothelial parameters in patients with erectile dysfunction (ED), including intima-media thickness (IMT) of common carotid arteries (CCA) and flow-mediated dilatation (FMD) of brachial artery. Fifty-six ED patients were included in the study. Penile CDS, IMT of CCA and FMD of brachial artery were performed in all patients. According to penile CDS findings, 27 (48%) patients had non-vasculogenic and 29 (52%) patients had vasculogenic ED. Among 29 patients, 17 (30%) patients had cavernous veno-occlusive disease (CVOD) and 12 (22%) patients had arterial/combined insufficiency (AI). Median (interquartile range) FMD values of non-vasculogenic ED, CVOD and AI were 12.50 (6.54)%, 12.82 (7.41)% and 6.25 (7.17)%, respectively. FMD was found to be impaired significantly in AI group when compared to the other groups. FMD values of CVOD group were lower when compared to non-vasculogenic group, but the difference was not statistically significant. IMT values of vasculogenic ED patients were higher than non-vasculogenic ED patients (P<0.05). Although IMT values were higher in AI group when compared to CVOD, the difference was not statistically significant. The combined use of IMT and FMD established the diagnosis of vasculogenic ED with 100% sensitivity and 59.2% specificity. The positive predictive value was 72%, negative predictive value 100% and accuracy 80%. The combined use of brachial artery FMD and carotid arteries IMT measurements may be suggested as an alternative method to evaluate vasculogenic ED.

Abstract
INTRODUCTION A lack of standardization of the recording techniques of corpus cavernosum electromyography (CC-EMG) and objective criteria to characterize the recorded signals (CC-potentials) are the main difficulties hindering the clinical application of this method. These difficulties have been recently overcome by revising the recording and interpretation methodology of CC-EMG AIM: To assess if CC-EMG performed with the revised methodology is discriminative for well-defined clinical conditions in patients with erectile dysfunction (ED). METHODS Based on blinded clinical diagnosis, ED patients were catalogued into five subgroups: severe penile fibrosis, cavernous arterial insufficiency (CAI), cardio-vascular comorbidity (CVCM) without proven CAI, post-radical retropubic prostatectomy (RRP), and psychogenic ED. With four electrodes placed on the penile shaft bilaterally, CC-EMG was recorded monopolarly for 30 minutes during flaccidity. After evaluation of the recordings by visual inspection, CC-potentials were analyzed using cross- and autocorrelation techniques. The parameters evaluated were amplitude, duration, dominant frequency (DF), and maximum cross-correlation coefficient (Rmax) of CC-potentials recorded from proximal and distal parts of the CC. MAIN OUTCOME MEASURES Comparison of the values of parameters amplitude, duration, DF, and Rmax between patient and control groups. RESULTS A total of 119 patients with ED and 43 men with reported normal erectile function were studied. Thirteen out of 14 patients with severe penile fibrosis did not show any distinguishable CC-potential. Patients with CAI had significantly decreased amplitude compared with the potent controls, as well as the patients with CVCM but without proven CAI. Significantly decreased amplitude and Rmax were detected in ED patients following RRP compared with the controls. CONCLUSIONS Corpus cavernosum electromyography performed with the revised methodology is able to discriminate ED patients with conditions that are associated with cavernous smooth muscle degeneration and/or autonomic neuropathy from men with reported normal erectile function.

Abstract
INTRODUCTION Systemic sclerosis is a connective tissue disease characterized by Raynaud's phenomenon, degenerative changes and vascular lesions in the presence of thickened, sclerotic skin lesions determined by cellular proliferation, and excess of extracellular matrix production. The role of ultrasound in the investigation of penile pathology is well established as vasculogenic impotence accounts for more than 30% out of overall causes. AIM In this article, we report for the first time the extent of penile vascular damage in a series of 15 sclerodermic patients (mean age 47 +/- 12.5 SD) under current treatment for their disease irrespective of their sexual dysfunction complaints. METHODS After disease classification (mean duration of disease 7.2 +/- 5.1 years), all patients were interviewed about the presence or absence of erectile dysfunction (ED) by using the Sexual Health Inventory for Men (SHIM) questionnaire, and then blood flow velocity in the cavernous artery following standardized pharmacostimulation was determined with Duplex ultrasonography along with the intima media thickness (IMT) of the common carotid artery, a valid index for atherosclerosis. RESULTS Mean SHIM scores revealed the presence of moderate-to-severe ED (mean 13.3 +/- 6.3). Interestingly, in all patients diffuse hyperechoic "spots" inside the corpora cavernosa along with thickening of the tunica albuginea were found. Severely impaired mean peak systolic velocities (20.2 +/- 5.5 cm/second) in the presence of mild venous leakage as expressed by mean end diastolic velocities (4.6 +/- 2.9 cm/second) were found along with normal IMT (0.065 +/- 0.010 cm) and acceleration time (92.3 +/- 32.7 cm/second). CONCLUSION Penile fibrosis almost invariably occurs in sclerodermic patients and this determines incomplete penile arterial and smooth muscle cell relaxation and ED despite the absence of indirect signs of early atherosclerosis, that is, abnormal IMT and acceleration time.

Abstract
Erectile dysfunction (ED) is the consistent inability to achieve and maintain an erection sufficient for satisfactory sexual activity. Erectile dysfunction affects as many as 30 million men in America, with an increasing prevalence with age. Erectile dysfunction is secondary to organic, psychogenic and combined causes. The first part of this review article describes the guidelines for evaluation and treatment plans for men with ED. It also describes the normal sonographic anatomy of the penis, sonographic technique for evaluation of ED and the normal phases of erection.

Abstract
Male sexual dysfunction-a term that is commonly used to refer to erectile dysfunction, premature ejaculation, decreased libido and impaired orgasm-is the primary complaint encountered by many urologists. Despite the high prevalence and bothersome nature of these complaints, they are frequently neglected in clinical practice. This paper highlights clinical situations in which urologists should systematically evaluate male sexual functioning. These include men who present with several common urologic disorders, such as pelvic trauma, malignancies, and lower urinary tract symptoms associated with benign prostatic hyperplasia, neurologic disorders and infertility. Studies have shown that erectile dysfunction might be a clinical marker of endothelial dysfunction, and consequently of undetected diabetes, hypertension, dyslipidemia, coronary artery disease and depression. We also address the question of whether urologists should adopt wide-ranging screening regimens for sexual dysfunction.

Abstract
A number of disease processes of the penis including Peyronie's disease, priapism, penile fractures and tumors are clearly visualized with ultrasound. Diagnostic evaluation of erectile dysfunction (ED) by penile dynamic colour-duplex Doppler ultrasonography (D-CDDU) is actually considered a second level approach to ED patients because of the fact that intracavernous injections test IV with prostaglandin-E(1) may provide important information about the patients' erectile capacity. However, no direct vascular imaging and a high percentage of false negative diagnoses of vasculogenic ED are its major pitfalls and subsequent treatment decisions remain quite limited. The occurrence of ED and its sentinel relationship to cardiovascular disease has prompted more accurate vascular screening in all patients even in the absence of cardiovascular risk factors. The sonographic evaluation of the intima-media thickness of the carotid arteries may sometimes represent an early manifestation of diffuse atherosclerotic disease and endothelial damage. This latter finding is often the cause of failure to oral agents, i.e. phosphodiesterase inhibitors, because of inability of the dysfunctional endothelium to release nitric oxide. D-CDDU represents an accurate tool to investigate cavernous artery inflow and venous leakage when compared with more invasive diagnostic techniques i.e. selective arteriography and dynamic infusion cavernosometry along with cavernosography.

Abstract
INTRODUCTION Impaired perfusion of the corpora cavernosa is considered an important causal factor of erectile dysfunction (ED) in the aging male with atherosclerosis. Aim. On the basis of this notion, we hypothesized that inhibition of angiotensin-converting enzyme (ACE) may have a structural beneficial effect on cavernosal perfusion and subsequently on erectile function in men with impaired cavernosal perfusion. METHODS A total of 59 men with atherosclerotic ED (mean age, 60.0 +/- 6.8 years) and impaired cavernosal perfusion, as demonstrated with penile-pharmaco duplex ultrasonography, were randomized between an ACE inhibitor and placebo treatment arm. The minimum period of intervention was 26 weeks (26-46 weeks). The goal of the study was to demonstrate an improvement of (i) cavernosal arterial perfusion demonstrated by a decrease of blood flow velocity waveform; and (ii) erectile function in the erection domain of the International Index of Erectile Function. RESULTS Cavernosal perfusion improved significantly (paired samples t-test, P < 0.05) in both study arms, but the improvement did not differ significantly (anova, P > 0.05) between both arms. The number of sexually active men increased, and the severity of ED decreased in both groups. CONCLUSION Although a persisting improvement of cavernosal perfusion by at least a 6 month-administration of an ACE inhibitor in men with advanced atherosclerotic ED could not be demonstrated in this pilot study, the beneficial effect on cavernosal perfusion, sexual activity, and erectile function in all participants of this study is remarkable. This pilot study warrants a follow-up study in sexually more active men with ED and less advanced atherosclerosis to show that ACE inhibition may result in persisting improvement of cavernosal perfusion.

Abstract
OBJECTIVES To assess the role of measuring cavernosal artery blood flow as a screening tool for ischemic heart disease in patients with erectile dysfunction (ED). METHODS A total of 303 male patients with ED were enrolled in this study. Patients were interviewed for ED using the International Index of Erectile Function. The penile vasculature was assessed using color Doppler ultrasonography and the Digital Inflection Rigidometer. All patients were referred to a cardiologist for evaluation of ischemic heart disease (IHD). All patients underwent routine laboratory investigations, plus total testosterone and prolactin assessments. RESULTS Seventy-six percent of the patients had organic causes of ED. Of the 303 patients, 31.4% had different degrees of IHD. A statistically significant association was found between the presence of IHD and arteriogenic causes of ED, a poor response to intracorporal injection, poor rigidity in the Digital Inflection Rigidometer, and low peak systolic velocity (PSV) in the cavernosal arteries (P <0.05 for each). No statistically significant association was found between the presence of IHD and increasing end-diastolic velocity values or decreasing resistive index in the cavernosal arteries (P >0.05 for each). A statistically significant association was found between a higher grade of IHD and a decreasing PSV value (P <0.05). CONCLUSIONS The results of this study established that a reduced PSV of the cavernous artery is associated with IHD. Determining the PSV could be a reliable screening tool for the detection of IHD in patients with ED.

Abstract
PURPOSE OF REVIEW This is an update of recent developments in the investigation of erectile dysfunction in the period since March 2002. RECENT FINDINGS Three developments in the field of medical sexology redirected the approach towards the investigation of erectile dysfunction. First, the emergence of oral pharmacological therapy; second, the notion that sexual relationship issues have an important impact on the successful outcome of pharmacological therapy; and finally, the concept that erectile dysfunction is often a sequel or even a sentinel of cardiovascular disease. Consequently, the current evaluation of men with erectile dysfunction may be divided into two steps: a basic diagnostic evaluation for the majority of men, and specific diagnostic procedures for a small minority. The basic evaluation is aimed at the identification of the underlying pathological condition and erectile dysfunction-associated risk factors. Such screening may diagnose reversible causes of erectile dysfunction and also unmask medical and psychological conditions that manifest with erectile dysfunction. The basic evaluation consists of a comprehensive medical, sexual and psychosocial history and a physical examination. Patients who have failed first-line treatment or complicated cases qualify for specific diagnostic procedures, traditionally performed by urologists. SUMMARY Current research into the investigation of erectile dysfunction emphasizes the notion that erectile dysfunction is often a result of an interplay between medical and psychosexual conditions. Recognition of the underlying conditions and an estimation of their relative contribution to the patient's and his partner's sexual problem are key issues in the current evaluation of the man with erectile dysfunction.

Abstract
OBJECTIVES Erectile dysfunction (ED) is a common disorder of aging male and about 50% of the ED sufferers consult a physician in the Netherlands. As ED is strongly correlated with cardiovascular diseases, we explored how many patients with ED aged 40 to 69 years will develop cardiovascular disease in the Netherlands and, philosophize if and which preventive measures are available to reduce cardiovascular risks in this specific population. METHODS 158 patients were included and were comprehensively evaluated. All patients underwent a penile-pharmaco duplex ultrasonography to evaluate the penile vascular status and a cut-off value for acceleration time of 100 ms was used to distinguish between patients with and without cavernous arterial insufficiency. Framingham risk functions were used to determine the 4 to 12 year coronary heart disease risk. The results were extrapolated to the Dutch ageing male population. RESULTS In the age group 40 to 49 years and 60 to 69 years no significant difference was detected in coronary heart disease risk between patients with and without cavernous arterial insufficiency. In the age group 50 to 59 years patients with cavernous arterial insufficiency showed a significantly increased risk to develop coronary heart disease. It is estimated that in total, more than 25,000 ageing men with ED will develop coronary heart disease within 4 years and increases to almost 75,000 men within 12 years in the Netherlands. CONCLUSIONS Screening on cardiovascular risk factors and taking preventive measures is recommended in men with ED. Men with cavernous arterial insufficiency aged 50 to 59 years are especially prone to develop coronary artery disease.
