Two-piece inflatable and semi-rigid penile implants: an effective alternative?

Penile prostheses (PPs) are an excellent treatment to be considered for patients suffering from erectile dysfunction (ED), refractory to oral medications, or unwilling to consider intracavernosal injections or other therapeutic strategies. Nowadays the market is dominated by three-piece inflatable penile prosthesis (IPP), which are considered the best option available. However, in some specific cases three-piece IPP may be superseded by semi-rigid penile prosthesis (SRPP) and two-piece IPP. Despite the advantages of these implants, the literature is quite scarce, not robust and rarely takes into consideration the partner's satisfaction. This clearly affects the strength of our conviction. Most of the studies confirm that SRPPs and two-piece IPPs can be considered a valid alternative in patients with hand dexterity issues, refractory ischaemic priapism, neophallus and in cases of complex anatomies. In addition, the ease of placement and the high confidence level of surgeons make them a powerful tool in the armamentarium of urologists.
