Extracorporeal Transseptal Penile Prosthesis Implantation for Extreme Cases of Corporeal Fibrosis: Shaeer Implantation Technique

Abstract Background Penile prosthesis implantation into scarred corporeal bodies is one of the most challenging procedures in prosthetic urologic surgery, especially following infection and extrusion of a penile implant. Several instruments and techniques have been used for making dilatation of scarred corporeal bodies easier and safer in expert hands. Nevertheless, in some cases, implantation is not possible. Aim This work presents extracorporeal transseptal implantation as a last resort in such cases. Methods In 39 patients with extensive corporeal fibrosis, penile prosthesis implantation is attempted. After failure of alternative techniques, extracorporeal implantation is resorted to in 10 patients. The corpus spongiosum is identified and protected. Diathermy knife is used to cut a longitudinal window into 1 corpus cavernosum, through the septum and into the contralateral corpus cavernosum. A single semirigid implant rod is inserted through the window at the base of the penis, halfway through. The 2 limbs of the rod are bent upward toward the glans, to assume a U shape. The limbs of the U are brought together at midshaft by a gathering suture passed through the corpora cavernosa and septum. The tips of the U are anchored under the glans. Outcomes Achievement of acceptable coital relationship. Results The procedure allowed acceptable coital relationship and concealment in 9/10 cases. In 1 case, infection occurred. Reimplantation with the same method was performed 6 months later, and the implant survived adequately. Perforation, migration, and urethral injury were not encountered. Clinical Implications This technique may help salvage abandoned cases with corporal fibrosis, particularly when the necessary expertise for alternative techniques is unavailable or when such techniques fail. Strengths & Limitations The technique presented is fairly straightforward and safe. However, the number of cases and duration of follow-up are limited. Conclusion Extracorporeal transseptal penile prosthesis implantation can salvage cases with severe corporeal fibrosis when all alternatives fail.
