The penile brachial index involves measuring penile pressure and comparing it with arm pressure. It has limited clinical utility because the data are based on superficial and deep penile arterial pressure, whereas erectile function depends on the deep arteries exclusively. Duplex ultrasonography allows for refined assessment of the penile circulation. The information it provides, however, is operator dependent and rarely alters patient management. Selective pudendal arteriography combined with intracavernous injection of a vasoactive drug should be limited to the small group of patients who are candidates for penile revascularization surgery. These patients include nonsmoking men less than 40 years old with a history of pelvic trauma who have sustained a penile arterial disruption.30 Doctors at the Rambam Medical Centre in Haifa, Israel, recruited 20 men with an average age of 56 to take part in the trial.
