title: [Priapism: Current diagnostics and therapy].
abstract: Priapism is characterized by involuntary persistent penile erection after or independent of sexual stimulation. The diagnostic clarification, including patient history, physical findings, duplex ultrasonography and analysis of blood gases is decisive for the underlying pathophysiology and the appropriate therapeutic procedure. Non-hypoxic and non-acidotic blood gas parameters enable a conservative approach, hypoxic, hypercarbic and acidotic parameters may lead to fibrosis of the corpora cavernosa and, in turn, to a loss of penile function. Low-flow or ischemic (veno-occlusive) priapism is an emergency situation and can lead to irreversible erectile dysfunction within 4 h. Treatment consists of blood aspiration and possibly intracavernosal injection of sympathomimetic drugs. A distal shunt is necessary in the case of treatment failure (in rare cases a proximal shunt). Management of recurrent priapism (stuttering) includes self-injection of sympathomimetic drugs and preventive long-term administration of erection inhibitory and erection promoting substances. This concept still needs to be validated. High-flow or non-ischemic priapism does not necessitate immediate treatment measures and should be kept under observation. In cases of a detectable fistula selective artery embolization is often a successful option.
