[Highflow priapism : diagnostic evaluation, contribution of ultrasound and recommendations].

The high flow priapism (HFP) is a very rare pathology. It must be distinguished from the low flow which is a real urologic emergency. The diagnosis of HFP (most often post-trauma) remains clinical, but penile color Doppler ultrasound can confirm, identify and track the evolution of the lesion. Conservative treatment is effective and remains the first line treatment. However the different therapeutic modalities (selective embolisation, surgery) should be explained to the patient and be considered case by case.
