Penile duplex: clinical indications and application

International Journal of Impotence Research volume 31, pages 298–299 (2019)Cite this article

Butany et al. [1] report the results of a 30-question electronic survey distributed to members of the International Society for Sexual Medicine (ISSM). The survey assessed the variability in the current Penile Duplex Ultrasonography (PDU) practice patterns, technique and interpretations. Although the response rate was only 9.5%, the cohort consisted of 190 respondents of which 126 (66%) had been practicing for greater than 10 years. The authors report significant heterogeneity in the practice patterns of PDU.

Penile ultrasonography is a non-invasive imaging modality that evaluates macroscopic penile anatomy including assessment of penile vascular flow thus providing information pertaining to functional status of an erection [2]. The American Institute of Ultrasound in Medicine (AIUM) in conjunction with the American Urological Association (AUA) published the AIUM Practice Parameter for the Performance of an Ultrasound Examination in the Practice of Urology in 2011 [3]. The indications for penile ultrasound in urological practice ranged from evaluation of priapism, dorsal vein thrombosis, and penile tumors. In 2015, the AUA published their guidelines on Peyronie’s Disease (PD), which states an in-office intracavernosal injection (ICI) test with or without PDU should be performed prior to invasive intervention (expert opinion) [4]. Most recently, the AUA published their 2018 guidelines on ED and described that PDU may provide information differentiating primary psychogenic versus organic etiology of ED, identification of men with severe veno-occlusive dysfunction resulting in ED who are unlikely to respond to medical therapy and identify men who may be candidates for penile revascularization procedures [5].
