Surgical Technique for Complex Cases of Peyronie's Disease With Implantation of Penile Prosthesis, Multiple Corporeal Incisions, and Grafting With Collagen Fleece

Abstract

Introduction: Patients with Peyronie's disease (PD) and erectile dysfunction (ED) concomitant with shortening or other malformations benefit from prosthesis implantation and penile lengthening procedures.

Aim: To evaluate the safety and efficacy of a multi-incisional technique with penile prosthesis implantation with multiple corporeal incisions and collagen grafting for the surgical management of complex cases of PD with ED and severe penile shortening.

Methods: From February 2015-May 2018, 43 consecutive patients with complex PD were treated using this technique. Implantation of a penile prosthesis (malleable or inflatable [IPP]) together with multiple relaxing tunica albuginea incisions and grafting with a self-adhesive collagen-fibrin fleece (TachoSil, Baxter Healthcare) was performed in all patients by a single surgeon (J.I.M.S.).

Main outcome measure: Penile length and curvature correction, operative time, and incidence of postoperative complications were recorded as outcome measures. Functional outcomes were measured with questionnaires (International Index of Erectile Function-5, Erection Hardness Score, modified Erectile Dysfunction Inventory of Treatment Satisfaction questionnaire, PD Questionnaire) before and 3 and 6 months after surgery.

Results: With a median follow-up of 21 months (range 10-31), mean postsurgical penile lengthening was 2.5 (range 1-5) cm, with an improvement in the Bother domain of the PD Questionnaire of 4.4 (range 2-5) points. The average operative time was 86.7 and 71.6 minutes for the IPP and malleable penile prosthesis procedure, respectively. No glans ischemia was recorded; however, 1 IPP infection and 1 delayed distal corporeal erosion were recorded. Hematoma or bruising was observed in 23.2% of patients. The modified Erectile Dysfunction Inventory of Treatment Satisfaction questionnaire was completed by 39 (90.7%) patients. Overall, 89.7% would recommend this surgery. Patient satisfaction with straightness and length was 94.9% and 82.1%, respectively.

Clinical implications: The described technique helps restoration of penile length and erectile function in patients with complex PD.

Strengths & limitations: The strength of the study is that it offers a simple, easy-to-apply technique for surgeons to correct shortening and other malformations in patients with ED and complex PD. The study is limited by the small number of patients, the short follow-up period and the performance of the technique by a single high-volume implanter.

Conclusion: The implantation of a penile prosthesis (malleable or inflatable) together with multiple incisions of the plaque/tunica albuginea and grafting with a collagen fleece is a safe and efficient treatment for patients with complex PD in addition to ED and significant shortening.
