Intracavernous injections and vacuum constrictor devices have been used for the nonoperative management of impotence and sexual dysfunction. Although most men are able to use these methods successfully, it currently is well known that up to 30 to 35 per cent of the patients may have only a partial response to the injections. We observed 22 men with partial tumescence after an intracavernous injection of papaverine (15 to 30 mg.) and phentolamine (0.5 to 1.0 mg.). The penis was not rigid and the buckling pressures never exceeded 50 mm. Hg after 20 minutes of observation. In each case we immediately applied a vacuum constrictor device because these devices had been used successfully by other men with similar diagnoses. A total of 21 men responded within 30 to 60 seconds and achieved a rigid erection with buckling pressures of greater than 100 mm. Hg (16) and 60 mm. Hg (5). These findings indicate that a vacuum constrictor device may be used to augment a partial response to an intracavernous injection and that the availability of injections and vacuum constrictor devices provides these men with a more complete nonoperative program.
