Priapism due to glyceryl trinitrate in adult intensive care unit: A case report

Priapism is a prolonged penile erection without sexual stimulation. Two forms of priapism are recognized: veno-occlusive or low-flow priapism and arterial or high-flow priapism. High-flow (arterial) priapism is usually the result of straddle injury. Treatment of high-flow priapism may be elective Low-flow priapism is usually related to sickle cell disease, haemoglobinopathies, neoplastic syndrome, psychotropic medication, anticoagulant therapy, or idiopathic causes. Low-flow priapism is a case of urologic emergency and priapism must be treated as emergency. A 52-year-old man was admitted to the neurology intensive care unit with the diagnosis of stroke. Glyceryl trinitrate was applied to the patient for the treatment of hypertension. In our case, Low-flow priapisms were completely due to glyceryl trinitrate therapy applied at the insensive care. We report a case of prolonged low-flow priapism induced by Glyceryl trinitrate. In literature, this is the first report of glyceryl trinitrate-associated priapism.
