“…In order to avoid these disadvantages, measuring PSV in the flaccid state were applied. The correlation of the PSV value between flaccid state and erectile state were found by their study (Souper et al., 2017). A study showed that flaccid PSV <13 cm/s predicts reduced dynamic PSV with an accuracy >80% (Corona et al., 2008).…”

The gold‐standard method for diagnosing arteriogenic erectile dysfunction (AED) is the penile Doppler ultrasonography. We proposed a novel method for predicting AED using ultrasonic shear wave elastography (SWE) considering that the former was invasive and variable. A total of 98 male patients were enrolled in our study, referred for ED between December 2018 and October 2020. For comparison, we also included 42 volunteers from the Healthy Physical Examination Center of our hospital. The Penile Doppler Ultrasonography (PDU) and SWE were performed for all patients with the intracavernosal injection (ICI). We named three groups as AED group, nonvascular ED group and healthy controls group. No statistically significant differences were found among the three groups in terms of demographic and clinical characteristics. There were no significant differences in IIEF‐5 between AED and nonvascular ED. A significant (r = 0.642, p < 0.0001) positive correlation between flaccid and erectile SWE was observed. With a cut‐off value of 13.45 KPa, the area under curve, specificity, and sensitivity of the SWE values under the flaccid state in distinguishing AED from healthy subjects were 0.867, 0.786 and 0.896 respectively. The SWE value in the flaccid state can distinguish the AED from healthy subjects.

“…Combined audiovisual sexual stimulation and intra-cavernous injections would not only increase the objective response of penile erection but also improve subjective sexual arousal and satisfaction by providing a comfortable environment (40). Although there is a consensus in guidelines to use CDDU to detect dynamic parameters after intra-cavernous injections (41), recent studies have claimed that PSV in a flaccid state also has a good predictive value for arterial dysfunction (51,52). A study of 1,346 male patients found that the diagnostic accuracy of PSV with 13 cm/s as the threshold in flaccid state was more than 80% (53).…”

Vascular erectile dysfunction (ED) is closely related to cardiovascular events, and early diagnosis of vascular ED may be helpful to predict the occurrence of cardiovascular events and improve prognosis.At present, there are many approaches to diagnose ED, but each method has its advantages and limitations.This study retrospectively reviewed all available literature focusing on the diagnosis of vascular ED through a systematic PubMed and EMBASE search. According to the different application scenarios, the main methods for the diagnosis of vascular ED are divided into four categories. Intra-cavernous injection of vasoactive drugs is the earliest method used in the diagnosis of vascular ED and is a basic test. For the diagnosis of arterial ED, color duplex Doppler ultrasound, selective penile angiography, magnetic resonance imaging, and computed tomography are more commonly used. While for the diagnosis of venous ED, shear wave elastography, dynamic infusion cavernosometry and cavernosography are more accurate. Endo-peripheral arterial tonometry (PAT) has also been used to detect vascular endothelial function. Although various existing examinations are widely used for the evaluation of vascular ED, they still have some shortcomings, such as invasiveness, contingency, high false positive (negative) rate. New methods of long-term dynamic detection are needed.
