Derivación safeno-cavernosa en un caso de priapismo de flujo bajo

Priapism is the painful, pathologically prolonged erection of the penis not related to sexual stimuli. It exists in two distinct forms: ischemic (low-flow) and non-ischemic (high-flow), both with different causes and treatment. Surgery is reserved as the last option and consists of distal or proximal systemic-cavernosal shunts. The case of a 22-year-old man with ischemic priapism and a history of use of antipsychotic drugs is presented. He was treated initially with cavernosal aspiration and injection of sympatomimetic drugs. We performed a Winter’s procedure without success and a sapheno-cavernous shunt which resolved the priapism. At a 9month follow up he maintained potency.
