[Development and clinical application of the Chinese-made inflatable penile prosthesis].
OBJECTIVE
To study the effect and safety of the Chinese-made inflatable penile prosthesis in the treatment of erectile dysfunction (ED).


METHODS
According to the anatomy and physiology of Chinese men, an inflatable penile prosthesis was developed in China, consisting of an innovated pump, a reservoir, and a pair of penile cylinders, which were connected by tubes to form a complete system. It was authorized to be used clinically by State Food and Drug Administration (SFDA). Forty-five cases of organic ED were selected for penile prosthesis implantation. Penoscrotal approach was used to implant the cylinders into the corpus cavernosum, the pump into the scrotum and the reservoir into the prevesical space.


RESULTS
Surgical problems and mechanical failures were not found in the subjects. Post-operative complications occurred in 3 cases (6.6%), but did not affect the intercourse. Satisfactory intercourses were achieved 10-12 months later and the intercourse duration averaged about (20 +/- 6) min.


CONCLUSIONS
The Chinese-developed inflatable penile prosthesis was safe and effective for patients with ED, with low rate of mechanical failures. Its long term effect has yet to be further studied.
