Trans-corporal incision of Peyronie's plaques.

INTRODUCTION: Patients presenting with Peyronie's disease (PD) curvature and erectile dysfunction (ED) can achieve straightening and rigidity through penile prosthesis implantation and manual modeling and, if necessary, a relaxing tunical incision with or without grafting. Unfortunately, this maneuver will not correct PD-induced shortening. In addition, incision and grafting after the prosthesis has already been implanted adds to operative time and risk, and may indicate mobilization of the neurovascular bundle and, possibly, a secondary skin incision.

AIM: This work describes trans-corporal incision (TCI), a minimally invasive endoscopic approach for plaque incision from within the corpora cavernosa, restoring straightness and length to the penis, before calibration of the corpora cavernosa, allowing implantation of a longer prosthesis in a straight penis, with neither mobilizing the neurovascular bundle nor a secondary incision.

METHODS: Sixteen patients with PD deformity and refractory ED were operated upon. Intra-operative artificial erection demonstrated the deformity. Through a penoscrotal incision, the corpora were dilated. TCI was performed to incise Peyronie's plaques at the point of maximum deformity. Artificial erection was re-induced and correction of curvature evaluated. Length was measured before and after TCI. Implantation proceeded as usual.

MAIN OUTCOME MEASURES: Penile straightness and length.

RESULTS: Following implantation, the penis was straight in all cases. Pre-TCI length of the corpora was unequal on either side. Post-TCI, both corpora were of equal length with an average increase of 2.5 cm (11.9%) on the right side and 1.9 (9.1%) on the left.

CONCLUSION: TCI; corporoscopic incision of Peyronie's plaques upon implantation of penile prosthesis is a minimally invasive approach that restores both straightness and length to patients with PD and ED, with neither mobilization of the neurovascular bundle nor plaque incision and grafting.
