Abstract
- The aim of this work is to assess the value of penile duplex in the prediction of intracavernous druginduced ischemic priapism. A total of 400 patients with erectile dysfunction were evaluated before and after diagnostic intracavernous injection of a trimix solution (papaverine þ phentolamine þ PGE1) using color Doppler sonography. In all, 29 patients experienced sustained rigid erections for more than an hour. Patients were further divided into two groups. Group A included patients with spontaneous resolution of their rigid erection within 3 h (10/29) and group B included patients with priapism (19/29) that did not resolve within 3 h. In group A, patients had minimal cavernous artery blood flow within the first hour postinjection, that increased with relief of their erection. Group B patients had no blood flow in their cavernous artery an hour after intracavernous injection and for 6 h later. The disappearance of blood flow in the cavernous artery after an hour of sustained rigid erection predicted priapism with 100% specificity and sensitivity. The persistent absence of cavernous artery blood flow for more than an hour, as detected by color Doppler ultrasound, is an objective predictor of priapism. This may guide early intervention to resolve the prolonged erection. International Journal of Impotence Research (2004) 16, 78–79. doi:10.1038/sj.ijir.3901152
