Changing diagnostic and therapeutic concepts in high-flow priapism.
High-flow priapism (HFP) is defined as pathological increased arterial influx into the cavernosal bodies. Since 1960, 202 cases have been published in the literature. This study evaluates the effect of the changing diagnostic and therapeutic concepts. The data of 202 cases of HFP was evaluated regarding diagnostic and therapeutic procedures and long-term results. Success was defined as restored erectile function without recurrent priapism. The major etiology of HFP is trauma, especially in children or young adults; in older men, HFP is a rare event mainly caused by malignoma. Cavernosal blood-gas analysis, color-Doppler ultrasound and angiography were the most effective diagnostic tools to distinguish high- from low-flow priapism. The success rate was 20% for shunt operations and 89% for arterial embolization. In conclusion, embolization was effective in the majority of cases of traumatic HFP, while shunt surgery remained disappointing. For HFP caused by inherited diseases and malignoma conservative therapy is mandatory.
