PREPUBERTAL HIGH FLOW PRIAPISM: INCIDENCE, DIAGNOSIS AND TREATMENT

Purpose: We reviewed the literature of the last 40 years and report our experience with treating high flow priapism with fistula embolization in prepubertal boys.Materials and Methods: Two boys had blunt perineal trauma and 1 had penile trauma (ages 6, 6 and 10 years). Painless priapism developed within 24 hours and lasted for 4 to 7 days before the patients presented to the hospital. Primary diagnosis was made on color Doppler ultrasound. When high flow priapism was diagnosed angiography of the internal iliac artery and embolization of the arteriocavernosal fistula were performed. Mean followup was 26 months.Results: Color Doppler ultrasound revealed bilateral arteriocavernosal fistulas in 2 boys and a unilateral fistula in 1. Angiography showed fistulas of the branches of the internal pudendal artery in 2 patients and fistulas of the bulbourethral artery in 1. Microcoils were used in the bulbourethral artery and a gelatin sponge was used in other penile arteries. Complete detumescence with restored erec...
