Cavernospongiosum shunt in management of priapism: is it a reliable method?
The efficiency of cavernospongiosum shunt in the management of priapism was evaluated in 10 patients. Technical details such as the "Z" perineal incision and the opening followed by closure of the contralateral corpus cavernosum, at the time of corpora evacuation, can improve the local exposure and permits a more complete drainage of the corpus cavernosum, but did not improve our results when they were compared with other techniques for treatment of priapism. Penile flaccidity and preservation of sexual potency occurred in 6 (60%) and 5 (50%) patients, respectively, and no surgical complications were observed. Immediate penile flaccidity and regaining of physiologic erection were, however, not complete even in the successfully treated patients. The cavernospongiosum shunt does not seem to represent the definitive form of treating priapism. New knowledge about mechanisms involved in priapism has to be obtained, in order to improve the approach and the prognosis of this disabling condition.
