Nonischaemic priapism associated with selective serotonin-3 receptor antagonist

Abstract

Priapism is a rare but severe urological emergency of erection of penis in the absence of physical and psychological sexual stimulation. Priapism is often idiopathic and is commonly associated with medications and underlying medical or traumatic causes. In this report, we present a case of a 70-year-old White Caucasian man who developed priapism after the administration of ondansetron, which is a selective serotonin type-3 (5-HT3) receptor antagonist. This case is unique, because, to date, there are only two presented cases in literature. The objective of this case report is to highlight the importance of recognising the possibility of priapism with ondansetron because this condition is not commonly seen in clinical practice to be associated with ondansetron and may go unrecognised. Also, potential pathophysiological mechanisms involved in the development of ondansetron-induced priapism are presented.

Spontaneous detumescence and full restoration of erection in a patient with high-flow priapism with persistent arterial-lacunar fistula after repeated selective embolisation-A case report

“…In some cases, high‐flow priapism could occur after intracavernous injections or shunting procedures for low‐flow priapism (Lutz, LaCour, & Hellstorm, ). High‐flow priapism due to malignant erosion of penile vessels or after drug administration is extremely rare (Kilciler, Kilciler, Kadihasanoglu, & Atahan, ).…”
