Preservation of erectile function by artery sparing dilation of the corpora cavernosa in prolonged priapism

Prolonged low-flow priapism causes structural impotence. We describe a case where potency has been preserved by off-centre corporal dilation to spare the cavernosal arteries. The patient suffered from idiopathic priapism lasting more than 72 hours before presentation. Corporoglanular shunts were performed thrice over a period of six days, twice also performing off-centre corporal dilation along the inside of the tunica. The idea was not to damage the central cavernosal arteries. Corporal blood supply spontaneously improved. Successful intercourse was possible after six months. Artery sparing cavernosal dilation techniques might improve spontaneous recovery in select cases.
