[External devices: for which patients?].
Vacuum therapy is a reversible, non-invasive form of treatment for partial impotence, with great success in USA. The story of vacuum therapy begins about 1960, when Osbon developed a vacuum tumescence device which he personally used for more than 20 years. The device was made commercially available many years ago and has been marketed under several names. The newer systems have incorporated a negative pressure pump to achieve vacuum. Osbon's system was patented in 1983, sale is permitted by the U.S. Food and Drug Administration, and it is available by prescription only. More than 10,000 units have been sold. There are four different types of vacuum therapy: 1) loading cone + constriction band; 2) external splint + negative pressure; 3) Negative pressure + constriction band; 4) Negative pressure + intracavernous injections, without the use of constriction band. Each basic system will be described. The authors make a comparison between the use of negative pressure devices plus tension band and the use of negative pression devices without tension band (plus C.I.D. with vaso-active agents). In the second case there's a sort of synergistic action between vaso-active agents and vacuum therapy, representing a sort of "vaso-active exercise" of the erectile tissue. There are no absolute contraindications to use of external penile devices and potential contraindications are few. The external penile devices described represent a reversible therapeutic modality that can augment an inadequate erection and they should prove useful in any man who needs erectile enhancement. These devices appear to be particularly effective in men with partial impotence in whom only erectile enhancement is needed.
