[Intracavernous injection: a treatment modality for erectile dysfunction].

A 56-year-old man presented with a 12-year history of erectile dysfunction, which caused him extreme distress with episodes of depression. Attempts with sildenafil did not improve his erections. We tried intracavernous injection of alprostadil which enabled the patient to achieve a moderate erection. Thus, we instructed the patient for self-injection, which led to sufficient erections over the following months. We then restarted with tadalafil as a monotherapy which then was successful.
