“…Colour Doppler ultrasonography (US) of the perineum and penis is not in routine use; however, in experienced hands, it can be useful to diagnose both ischaemic and non-ischaemic priapism [ 25 ] . Ischaemic priapism typically has minimal or no demonstrable arterial fl ow within the corpora carvenosa [ 25 ] .…”

Priapism is a disorder of persistent penile erection unrelated to sexual interest or desire. This pathologic condition, specifically the ischemic variant, is often associated with devastating complications, notably erectile dysfunction. Because priapism demonstrates high prevalence in patients with hematologic disorders, most commonly sickle cell disease (SCD), there is significant concern for its sequelae in this affected population. Thus, timely diagnosis and management are critical for the prevention or at least reduction of cavernosal tissue ischemia and potential damage consequent to each episode. Current guidelines and management strategies focus primarily on reactive treatments. However, an increasing understanding of the molecular pathophysiology of SCD-associated priapism has led to the identification of new potential therapeutic targets. Future agents are being developed and explored for use in the prevention of priapism.

Introduction: The objective of this study was to explore the role of intracavernous injection (ICI) and audiovisual sexual stimulation (AVSS) during real-time pharmacopenile Doppler ultrasonography (PDDU) in vasculogenic subtypes of erectile dysfunction. Materials and Methods: A total of 200 consecutive men with erectile dysfunction (ED) were enrolled. Each patient received 2 sessions of real-time PDDU. Session A was performed under ICI alone. Session B was performed under ICI plus AVSS. The interval between sessions was 7 days. Penile vascular parameters, including peak systolic velocity (PSV), end diastolic velocity (EDV) and resistive index, were monitored 5, 10 and 20 min after the start of the test. Patients were asked to describe the level of sexual arousal generated by choosing one of the pre-set answers. Results: In veno-occlusive ED, during session A, EDV at 10 min was significantly greater than at 5 and 20 min (p < 0.05). During session B, there was a significant difference regarding PSV in arteriogenic ED (p < 0.05). Mixed vasculogenic ED showed significant differences in PSV levels during session B, and EDV at 5 min was greater than at 10 and 20 min (p < 0.05). PDDU under ICI alone diagnosed 34 (17%), 35 (17.5%), 31 (15.5%) and 100 (50%) cases of arteriogenic, veno-occlusive, mixed vasculogenic and nonvasculogenic ED, respectively. The combination of ICI plus AVSS diagnosed 27 (13.5%), 44 (22%), 7 (3.5%) and 122 (60.7%) cases, respectively. Conclusions: Adding AVSS during PDDU improves the recording of physiologic erectile response and may help the physician to accurately evaluate the cause of ED.
