Penile Elastography Versus Penile Duplex Ultrasonography in Diagnosing Non-Responders to Intracavernosal Injection: A Prospective Cohort Study. JOURNAL OF ULTRASOUND IN MEDICINE : OFFICIAL JOURNAL OF THE AMERICAN INSTITUTE OF ULTRASOUND IN MEDICINE 2024; 43:77-84. [PMID: 37782750 DOI: 10.1002/jum.16339] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/24/2023] [Accepted: 09/08/2023] [Indexed: 10/04/2023]
Abstract
OBJECTIVES The current study aims to investigate the value of penile elastography in assessing the fibrotic changes in the corpora cavernosa. PATIENTS AND METHODS Eighty participants were included in the study. These were divided into two equal groups: a study group (group 1) included patients with ED who did not respond to intracavernosal injection (ICI), and an age-matched control group (group 2) included age-matched subjects with normal erection. All subjects answered an International Index of Erectile Function-5 (IIEF-5) questionnaire. The first group was evaluated by two ICI trials of 1 mL Quadmix, each took place 1 week apart, followed by a color duplex/Doppler ultrasonography (CDDU) scan using also a 1 mL Quadmix. All the above was done a week before the penile shear wave elastography (SWE) scan. It comprised a 12-section scan of both corpora cavernosa. Each corpus was scanned in three different segments (proximal, mid-shaft, and distal), and in both longitudinal and transverse axes. RESULTS Comparisons of the laboratory data were non-significant, apart from the glycosylated hemoglobin which proved significant (P value <.001) in both groups. Also, the IIEF-5 scores were significantly lower in the study group (P value <.001). Significantly higher SWE readings (indicating higher fibrotic) were found in the study group compared with the control group in almost all of the scanned segments and their combinations (P value <.05). CONCLUSION SWE can effectively assess the fibrotic changes occurring in the corpora cavernosa. Hence, SWE could be utilized as a modality that helps diagnose patients with ED.

Abstract
The aim of this article is to review the utility of elastography in the day-to-day clinical practice of the urologist. An electronic database search was performed on PubMed and Cochrane Library with a date range between January 2000 and December 2021. The search yielded 94 articles that passed the inclusion and exclusion criteria. The articles were reviewed and discussed by organ, pathology and according to the physical principle underlying the elastographic method. Elastography was used in the study of normal organs, tumoral masses, chronic upper and lower urinary tract obstructive diseases, dysfunctions of the lower urinary tract and the male reproductive system, and as a pre- and post-treatment monitoring tool. Elastography has numerous applications in urology, but due to a lack of standardization in the methodology and equipment, further studies are required.

Abstract
This study sought to investigate the correlation between Helicobacter pylori (Hp) and arteriogenic erectile dysfunction (ED). This study included 30 patients diagnosed with ED due to penile arterial insufficiency, in accordance with the International Index of Erectile Function scores and penile Doppler ultrasonography results, and 30 healthy individuals without ED in the control group. The levels of fasting blood glucose, serum lipid and C-reactive protein (CRP) were recorded. Enzyme-linked immunosorbent assay revealed that the levels of Hp-specific Immunoglobulin G (IgG) antibodies in the patient and control groups were 39.7 ± 23.2 and 21.0 ± 19.8 arbU/ml, respectively (p = .001); the mean CRP levels were 0.3 ± 0.2 and 0.1 ± 0.1 mg/dl, respectively (p = .01). A positive correlation was detected between ED and the levels of Hp-specific IgG and CRP. Further comprehensive studies supporting these preliminary results may facilitate the use of Hp seropositivity as an auxiliary marker in the diagnosis of ED. These findings may also guide future research on the clinical benefits of Hp eradication strategies for the prevention and treatment of ED.

Abstract
INTRODUCTION Erectile dysfunction (ED) is a condition that is very common all over the world, concerns about men and causes very important social problems. The aim of this study is to perform quantitative penile corpus cavernosum (CC) stiffness measurements by using SWE for patients with both types of vascular ED. METHODS In our study, we handled the data of 101 participants in total. The average age of the participants was 56.36. We divided the participants after color Doppler US (CDUS) into three groups: normal group (n = 30), arterial insufficiency (n = 51), and venous insufficiency (n = 20). SWE measurements were made in both groups in the CC flaccid (f) and rigid (r) positions, and the results were noted. International Index of Erectile Function (IIEF-5) questionnaire and Erection score (ES) were evaluated. RESULTS The mean CC f SWE and r SWE measurement values were 20.2 ± 0.8 and 17.15 ± 0.54 kPa, 3.84 ± 0.13 and 2.78 ± 0.11 m/s in the arterial insufficiency group; 15.72 ± 0.58 and 12.52 ± 0.33 kPa, 2.88 ± 0.06 and 2.09 ± 0.11 m/s in the venous insufficiency group; 14.75 ± 0.51 and 13.41 ± 0.36 kPa, 2.63 ± 0.1 and 2.34 ± 0.11 m/s in the control group, respectively. The CC measurement of f SWE and r SWE values as kPa showed significant differences between the groups (P < .001). CONCLUSION SWE can provide quantitative data with high specificity and sensitivity while evaluating CC penile stiffness noninvasively. It seems to contribute to the radiological evaluation of ED cases with useful data.

Role of shear wave elastography (SWE) in erectile dysfunction patients for evaluation of daily tadalafil treatment outcome. Andrologia 2022; 54:e14359. [PMID: 35019157 DOI: 10.1111/and.14359] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/22/2021] [Revised: 12/16/2021] [Accepted: 12/18/2021] [Indexed: 11/26/2022] Open
Abstract
The purpose of this study was to evaluate and anticipate the outcome of daily use of tadalafil in patients with erectile dysfunction using elastography. 183 volunteers and 183 patients with erectile dysfunction were included. Pretreatment SWE readings for our patients were calculated with a linear probe. IIEF score Q was measured once at the start of the study for volunteers and twice for patients, one prior to the start of tadalafil administration and the other on one year of 5 mg daily tadalafil after the second post-washout (one month post-treatment stopped). There was no significant difference between patients and volunteers in mean age or risk factors except in SWE values as mean SWE of volunteers was 14.03 ± 1.54 kpasc, while mean SWE of patients was 21.278 ± 8.228 kpasc. The presence of comorbid diabetes, severe disease and pre-SWE ≥23.635 was significantly associated with poor outcome. We conclude that penile SWE could be useful to select probable good responders for a continuous tadalafil use, thus avoiding the unnecessary cost and time in non-responders.

Abstract
Erectile dysfunction is a condition associated with increasing age. Patient evaluation and management should follow a comprehensive, stepwise approach. The aim of this article was to report our experience with the complete study for erectile dysfunction, including intracavernous injection rigidity test, biothesiometry and colour duplex Doppler ultrasound. Data were collected and analysed prospectively. The primary end point was to determine whether treatment decision-making was eased by the CompED test. Secondary end points were to establish which clinical variables prior to the study could impact the results of the CompED test, to finally improve patient selection for the study. 187 patients were recruited, 31.2% of the patients had an axial rigidity below 50%, 28.5% had a peak systolic velocity <25 cm/s, 13.2% had an end-diastolic velocity >5cm/s and 27.5% had an abnormal biothesiometry. The factors that best predicted an abnormal result in any of the tests were age >70 years, IIEF domain A < 14 points, and previous radical prostatectomy or radiotherapy. The CompED test stands as a new alternative for the evaluation of patients with erectile dysfunction, being less time consuming, aiding in a more accurate determination of the aetiology and guiding treatment decision-making.

Abstract
OBJECTIVES To explore the feasibility of shear wave elastography (SWE) in the evaluation of arterial erectile dysfunction (ED). METHODS From November 2018 to November 2019, 26 patients with arterial ED and 30 patients with non-vascular ED were prospectively included. SWE values of corpus cavernosum penis (CCP) and the flow velocity of cavernous artery for all patients in both before intracavernous injection (ICI) (flaccid state) and after ICI (erectile state) were measured. Performance of SWE value in assessing arterial ED was studied. Correlation between SWE value of CCP and the age of patients was also investigated. RESULTS ICI significantly reduced SWE values in both arterial and non-vascular group (from 19.57 ± 6.33 KPa to 12.17 ± 3.64 KPa in the first, and from 19.91 ± 6.69 KPa to 8.04 ± 3.13 KPa in the former, both P < .001). SWE values of CCP after ICI in arterial ED were significantly larger than that in non-vascular ED (P < .001). SWE values of CCP before ICI negatively correlated with age of patients in arterial ED (r = - 0.601, P < .001). With a cutoff value of 7.75 KPa, the area under curve, specificity, sensitivity, PPV, and NPV of SWE values of CCP after ICI in distinguishing arterial ED from non-vascular ED were 0.810, 63.3%, 96.2%, 96.2%, and 70%, respectively. CONCLUSIONS SWE was expected to be a potential technique for the noninvasive, simply operated, repeatable and quantitative evaluation of arterial ED.

Shear wave elastography as a new, non-invasive diagnostic modality for the diagnosis of penile elasticity: a prospective multicenter study. Ther Adv Urol 2021; 13:17562872211007978. [PMID: 33953801 PMCID: PMC8058793 DOI: 10.1177/17562872211007978] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2020] [Accepted: 03/15/2021] [Indexed: 12/13/2022] Open
Abstract
Objective: Shear wave elastosonography (SWE) could be used to evaluate the elasticity of penile tissue. Few studies in the literature, however, have investigated its use in patients with erectile dysfunction (ED) or have attempted to correlate findings with International Index of Erectile Function (IIEF-5) scores. The primary aim of this study was to evaluate the characteristics of erectile tissue using SWE and to determine possible relationships with IIEF-5 and Erection Hardness Scale (EHS) scores. The secondary aim was to establish a cut-off SWE examination value over which cavernous tissue stiffness could contribute to a subsequent organic alteration. Methods: This prospective study included male patients 18−80 years of age who attended two general andrology clinics and underwent SWE. Subjects were divided into groups according to IIEF-5 score, and correlations between SWE and IIEF-5 and EHS questionnaire scores were explored. Results: A total of 270 subjects (mean age 46.7 ± 16.9 years) were included. ED was reflected by low IIEF-5 and EHS scores and a decrease in the mean elasticity of the corpora cavernosa according to SWE, although the difference between the left and right corpora cavernosa was not statistically significant. No statistically significant correlation was found between measurements of the corpora cavernosa (in kPa) and age. The optimal cut-off identified was 24.75 kPa. Conclusion: Results demonstrated that the mean elasticity of the corpora cavernosa according to SWE was correlated with IIEF-5 score and EHS score.

Abstract
Background This study aimed to evaluate the efficacy and safety of holmium laser enucleation of prostate (HoLEP) by using en-bloc and bladder neck preservation technique on benign prostatic hyperplasia (BPH) and assess the influence of this procedure on urinary and sexual functional outcomes. Methods A total of 704 patients with BPH undergoing HoLEP were retrospectively analysed. Amongst them, 213 who met the sexual function assessment criteria were further assessed the influence of the technique on sexual functional outcomes. Results The mean operative time, resected prostate weight and mean estimated blood loss were 69.3±14.8 min, 53.4±17.6 g and 62.1±23.7 mL, respectively. The mean duration of catheterization after surgery and mean hospital stay were 2.1±1 and 5.4±3.6 days, respectively. The post-void residual volume, maximum urinary flow rate, international prostate symptom score and quality of life score were all significantly improved postoperation (P<0.05). Amongst the 213 patients with normal antegrade ejaculation before surgery, postoperative international index of erectile function scores slightly improved, although the difference was insignificant (P>0.05). The difference in the Erection Hardness Grading Scale before and after surgery was statistically insignificant (P>0.05). A total of 25 (11.7%) patients had retrograde ejaculation after surgery. Conclusions HoLEP by an en-bloc and bladder neck preservation technique can obtain good functional outcome with small injury and high efficiency, especially for patients who need to preserve normal sexual function and anterograde ejaculation.

Abstract
Background and Aims: Erectile dysfunction (ED) is an inability to achieve and maintain erectile rigidity sufficient for satisfactory sexual performance. It is either organic or psychogenic in origin. This study was aimed at establishing vasculogenic causes among patients being evaluated for ED using Penile Doppler Ultrasound. Methods: Fifty-two consecutive patients with the clinical diagnosis of ED were evaluated with color Doppler ultrasound scan using a 7.5 MHz high-frequency linear transducer between July 2016 and June 2019. The examination was commenced 3 min after an intracavernosal injection with 10-20 μg of PGE1 and continued for 30 min. The measurements were obtained alternately from both deep penile arteries. The variables analyzed were the peak systolic velocity (PSV), end-diastolic velocity (EDV) and resistive index (RI), calculated as (PSV-EDV)/PSV. Erection Hardness was evaluated subjectively using the EH Score (EHS), a 5-point response score denoting how the patient would rate his erection. ED was subjectively assessed using the International Index of Erectile Function (IIEF-5) questionnaire. In patients with a diagnosis of vasculogenic ED, intracavernosal PGE1 injection was started with a 5 μg dose and then increased in 5 μg increments until the final dose of 20 μg was reached. Results: PSV of cavernosal arteries (CA) varied between 19.2 and 106.2 cm/s (mean: 43.8 ± 18.2) among the entire patients and between 19.7 and 80.2 cm/s (mean: 42.6 ± 11.3) among patients with arteriogenic ED. Arteriogenic ED was found in 8 patients (15.3%), while venogenic ED was observed in 12 patients, which constituted 23% of the entire study population and mixed arteriogenic-venogenic ED was found in 6 patients (11.5%) of the study population. DICC performed on patients diagnosed with venogenic ED on color Doppler ultrasonography revealed venous leakage and no statistically significant differences between results of DICC and color Doppler ultrasonography were found in EDV, RI, and PI measurements (P< 0.005). Among patients with venogenic ED and mixed arteriogenic-venogenic ED,2 patients had a normal erectile response and the remaining 16 received 2 mg phentolamine. A significant increase in PSV between baseline and 20 mg PGE1 (P < 0.001) was observed in all cases. Following phentolamine, there was a significant increase in grade of erection (P = 0.0001) and a significant reduction in the EDV (P = 0.0001). A reduction of the EDV to below 0.0 cm/s was observed in 12 patients. In patients with arteriogenic erectile dysfunction, mean (±standard deviation) duration of erection for consecutive doses of PGE15 μg, 10 μg, 15 μg, and 20 μg were 42.2±18.4, 55.4±24.1, 66.1 ± 31.1, and 83.3±36.7 minutes, respectively, with significant increase for each dose. In patients with veno-occlusive dysfunction, mean durations of erection significantly increased from 9.1±8.0 minutes at 10 μg to 19.2±9.8 minutes at 20 μg. Conclusion: In the current study, 50% of patients had vasculogenic ED and “false-positive’’ diagnosis of venous leakage was unmasked by phentolamine re-dosing. It is therefore imperative that patients with ED benefit from duplex color Doppler ultrasonography which is safe, cheap and non-ionizing diagnostic modality before initiating therapy as ED treatment is cause specific.

Abstract
RATIONALE Priapism is a common urologic emergency, but high-flow penile priapism (HFP) caused by trauma is very rare. Therefore, HFP diagnosis and treatment are still not standardized. PATIENT CONCERNS A 29-year-old man was admitted to the urology department of our hospital on August 01, 2019, due to "persistent penile erection caused by a straddle injury." DIAGNOSIS On July 17, 2019, the patient underwent Doppler ultrasonography, which indicated swollen corpus cavernosum. INTERVENTIONS The patient took over-the-counter anti-inflammatory drugs but the erectile state of the penis remained unchanged. A second perineal injury resulted in hospital admission. Multimodality magnetic resonance imaging (MRI) scan showed nodular abnormal signals at the right corpus cavernosum root. Subsequently, selective arterial interventional angiography confirmed the MRI findings. Spring coils were then inserted for embolization, and the pseudoaneurysm, fistula, and priapism disappeared. OUTCOMES Two months after surgery, sexual stimuli could normally cause penile erection, with normal hardness. The patient's sexual life returned to normal 3 months after surgery. CONCLUSION Multimodality MRI is very effective in detecting high blood flow priapism. Its application would improve the clinical management of this ailment.

Abstract
Erectile dysfunction (ED) is defined as the persistent inability to achieve and/or maintain an erection for a satisfactory sexual activity. It is secondary to several organic, psychogenic, and combined causes, and represents a serious health dilemma affecting both men and their partners. The diagnostic approach to erectile dysfunction has significantly changed in the last years with the advent of phosphodiesterase-5 (PDE5) inhibitors, and with the recognition that surgical treatment of both arterial insufficiency and penile venous leak have poor long-term clinical outcomes. Although imaging modalities have diminished in importance, differentiating among causes of erectile dysfunction remains mandatory in good medical practice, and ultrasound (US) still remains the cornerstone of the diagnostic workup. US provides an objective, minimally invasive evaluation of penile hemodynamics. Moreover, it provides an excellent depiction of the penile anatomy and of its changes in pathological conditions such as in patients with Peyronie's disease, priapism, and posttraumatic erectile dysfunction.
