High-flow priapism after T-shunt and tunneling in a patient with ischemic priapism

Abstract

Priapism is defined as an erection lasting for more than 4 hours without sexual stimulation. It is grouped into 3 subtypes: ischemic (low-flow), nonischemic (high-flow), and stuttering priapism. Herein we describe a rare event of high-flow state as a result of conversion from a delayed ischemic priapism after a T-shunt with tunneling. To our knowledge, there is a paucity of reported cases, and the pathophysiology is still unclear. Clinicians should be aware of this uncommon but known scenario in case of penile tumescence after shunting procedure for ischemic priapism; penile Doppler ultrasound and selective pudendal angiography represent essential tools for diagnosis and treatment of this rare condition. In delayed ischemic priapism persisting for >36 hours, patients should be counseled about the irreversible damages of the cavernosal muscle and erectile dysfunction to consider an early penile prosthesis implantation with a satisfactory long-term functional outcome, decreasing the risks related to a distal shunt procedure.
