Objectives: Prosthetic surgery for impotence has been transformed by t
he use of inflatable prostheses, superseding the old semi-rigid design
s. Our objective is to report the functional results and the complicat
ions of this type of surgery. Methods: 80 inflatable prostheses were i
mplanted between October 1987 and October 1994, The mean follow-up was
3 years and assessment of the objective (mechanical functioning of th
e prosthesis and complications) and subjective results (sexuality of t
he patients) was made in 68 patients, Results: There were: 54.5% funct
ional disturbances, 7% infections, and 27.5% prosthesis removals. Most
of the patients were satisfied, although only 65% returned to regular
sexual activity, Conclusions: The choice between an inflatable and a
semi-rigid prosthesis should be carefully discussed because of the fre
quent mechanical complications that have been reported for the sophist
icated designs. Inflatable penile prostheses nevertheless remain the d
esign of choice. Their reliability has been increasing since the manuf
acture of monobloc designs. Such a device is costly, and should be com
pared with that of intracavernous injections.
