title: [Priapism associated with risperidone use: Report of one case].
abstract: The use of drugs with α-adrenergic antagonistic effect is one of the most prominent etiologies of priapism. We report a 32-year-old schizophrenic male in treatment with risperidone who consulted in the emergency room for a painful priapism. A low flow priapism was diagnosed. Medical treatment was unsuccessful and the patient was subjected to a proximal corporo-spongiosal shunt (Quackels technique), with good results. The patient was discharged in good conditions.
