High-flow priapism complicating ischemic priapism following iatrogenic laceration of the dorsal artery during a Winter procedure.

We report a case of a patient who developed high-flow priapism following a Winter procedure performed for the treatment of low-flow ischemic priapism. During the creation of bilateral cavernosal-glandular shunts, the tip of the left dorsal artery was accidentally lacerated. A fistula developed through the shunt between the torn artery and the cavernosal sinusoids of the tip of the left corpus cavernosum.

Color Doppler imaging of posttraumatic priapism before and after selective embolization.

High-flow priapism usually follows perineal or penile trauma with disruption of an intracavernosal artery. Angiographic embolization of the lacerated artery is currently considered the treatment of choice. The contribution of gray-scale and color Doppler ultrasonography (US) in diagnosis and treatment of 10 patients with high-flow priapism was investigated.

High-flow priapism: treatment and long-term follow-up.

Objectives: To determine the long-term follow-up of treatment of high-flow priapism, we reviewed the case records of 10 patients who were examined by the Urologic Clinic in Trieste from 1995 to 1998. High-flow or arterial priapism is a fairly rare dysfunction, generally resulting from penile or perineal trauma. In some cases, the etiology remains unknown.
