A minimally invasive temporary cavernoso-saphenous shunt in the management of priapism after failed conservative treatment

Abstract

Priapism is an urological emergency with detrimental consequences, if not managed expeditiously. Though a rare condition with an incidence between 0.3 and 1.5 per 100,000 population, its management options are limited and decision making could be challenging. We present a case of late presenting priapism for which the initial routine clinical care (aspiration, intracavernosal injection, and distal shunt) failed to relieve erection. Subsequently, the patient was successfully treated by a temporary cavernoso-saphenous shunt using carotid shunt and repeated heparin flushes. This novel surgical treatment offers an alternate method of relieving priapism, avoiding the long-term undesired effects associated with permanent proximal shunts such as cavernoso-venous grafts. Moreover, interval flushes (and/or repeated aspirations) with heparin ensures patency of this new shunt during the perioperative period. The patient recovered without any complications and the shunt was removed after one week. He has regained partial erection, however refused to have further treatment. Temporary cavernoso-saphenous shunt using carotid shunt offers an alternate option of management of priapism in patients with failed initial conservative treatment and distal shunts.
