title: Conversion of low-flow to high-flow priapism: a case report and review (CME).
abstract: Priapism is defined as an erection lasting greater than 4 hours. It is grouped into three subtypes: ischemic (low flow), nonischemic (high flow), and stuttering priapism. We present an interesting case and review of the conversion from a low-flow to a high-flow priapism. This conversion has rarely been reported. It has resulted from treatment of low-flow priapism with minimally invasive procedures including injection therapy as well as more invasive distal and proximal shunt procedures. Penile Doppler ultrasound and angiogram are particularly important to the clinician in the diagnosis and treatment of this rare entity.
