Priapism is a persistent penile erection lasting longer than 4 hours, without sexual stimulation. Priapism in people is categorized as either nonischemic (arterial, high flow) or ischemic (veno-occlusive, low flow). Nonischemic priapism, caused by increased arterial inflow through the corpus cavernosa, is often caused by trauma, but may also be the result of vasoactive drugs and neurological conditions. Ischemic priapism, caused by venous congestion to the penis and enhanced blood viscosity, is often associated with sickle cell disease, hematological dyscrasias, hemodialysis, parenteral nutrition, heparin therapy, vasoactive drugs, neoplasia, and neurological conditions such as spinal cord injury and anesthesia. A 10-month-old intact male German Shepherd dog was presented our clinics with the complaints of swelling in bulbus glandis, penile hyperemia and penile protrusion of 6 months’ duration. After the physical and neurologic examination, laboratory examination (complete blood count, serum biochemistry, cytological evaluation of venous blood, blood gas examination which was taken from corpus cavernosum penis), doppler ultrasonography and spinal MRI examination were performed. According to the findings, the patient was evaluated as non-ischemic priapism case and medical treatment was started in the light of literature. No significant improvement was observed in the patient after medical treatment. After all diagnostic procedures and medical therapy interventions, we concluded that previous publications suggesting that non-ischemic priapism can be succesfully treated with medical therapy in dogs must be evaluated in suspicion.
