Shaeer's infrapubic technique for penile prosthesis implantation through a single midline corporotomy: A single-center pilot study.

BACKGROUND

With the infrapubic approach (IPA) for penile prosthesis implantation, lateral corporotomies carry the risk of injury to the laterally coursing dorsal nerves.

AIM

We sought to describe for the first time Shaeer's IPA, a modification of the IPA whereby malleable penile prosthesis cylinders are implanted through a single midline corporotomy in the bed of the deep dorsal vein, anatomically off the course of the dorsal nerves of the penis.

METHODS

We compared semirigid penile prosthesis implantation via the single midline corporotomy IPA (IPA-S, n = 11) to the classic IPA with laterally placed dual corporotomies (IPA-D, n = 11) and to the penoscrotal approach (PSA; n = 13). Shaeer's IPA is performed through an infrapubic incision. A 3- to 5-cm length of the deep dorsal vein is stripped. A single 3- to 5-cm midline corporotomy is cut along the bed of the vein. Dilation, sizing, and implantation are performed through the single corporotomy on either side of the midline septum. Patients are discharged the same day and are allowed to bend the implant after 2 weeks and to commence intercourse after 3 weeks.

OUTCOMES

Operative time, postoperative satisfaction, International Index of Erectile Function 5 (IIEF-5), and possible complications were recorded.

RESULTS

There were no statistically significant differences in age, postimplantation IIEF-5, or satisfaction between the 3 groups. Average operative time for the IPA-S group was 21.8% shorter than that for the IPA-D group, and 34.5% shorter than for the PSA group. Those differences were statistically significant. No complications were recorded in the IPA-S group. Infection occurred in 1 PSA case, and partial hypoesthesia in 1 IPA-D case.

CLINICAL IMPLICATIONS

The midline corporotomy confers an anatomical advantage that may help avoid nerve injury, thereby increasing the safety of the IPA.

STRENGTHS AND LIMITATIONS

The main limitation of this study is the limited sample number, considering that this is a pilot study.

CONCLUSION

The Shaeer's Midline-Corporotomy IPA is a minimally invasive technique for implantation of a semirigid penile prosthesis, with an anatomical advantage that may decrease the possibility of dorsal nerve injury.
