Penile Extra-Tunical Graft Reconstruction of Peyronie's Disease Concavity Deformities

Extratunical grafting for minimally invasive management of complex Peyronie's disease deformities

BACKGROUND

Penile deformities due to Peyronie's Disease (PD) often significantly impair men's sexual health and quality of life.

AIM

In this article we discuss the extratunical graft (ETG) procedure as a management strategy for PD patients with hourglass or indent penile deformities.

METHODS

We compiled descriptions of surgical techniques and performed a review of the literature regarding ETG for PD.

OUTCOMES

The ETG procedure appears to have promising results in the management of indent/hourglass deformity of PD.

RESULTS

The findings of this review of the literature demonstrate that ETG is a safe and effective reconstructive technique for penile deformity with minimal side effects.

CLINICAL IMPLICATIONS

We recommend utilizing ETG with or without plication for PD patients with indent or hourglass deformities.

STRENGTHS AND LIMITATIONS

Strengths of ETG are the improvement in patients with tunical indents and hourglass deformities secondary to PD. Additionally, patients who underwent ETG maintained sexual function given no significant change in penile length and intact erectile function. Limitations, however, are that the procedure is relatively new, and data are limited to small cohorts.

CONCLUSION

The ETG procedure is a safe and effective for management of complex PD in the short- and intermediate-term follow-up cohort.

Grafts in Peyronie's surgery without the use of prostheses: a systematic review and meta-analysis

Peyronie's disease (PD) is characterized by abnormal penile curvature, and various surgical methods have been developed using different graft materials. However, there is currently no universal agreement on which type of graft is the best. The objective of this review was to evaluate the available literature and identify the most effective graft material for penile curvature correction in PD. A literature search was conducted using electronic databases, including PubMed, Scopus, and the Cochrane Library. The patients, intervention, comparison, and outcome (PICO) approach was used to define the eligibility of studies. Two authors independently selected studies, evaluated them, and extracted data. Random-effect models using the DerSimonian-Laird method were used. Most studies were single-arm studies and had a high risk of bias. Buccal mucosa grafts (BMG) were found to result in the highest penile straightening rates and were associated with the least de novo erectile dysfunction. TachoSil grafts demonstrated a high success rate in straightening despite a higher mean preoperative curvature, while Tutoplast grafts had a higher incidence of postoperative erectile dysfunction. BMG had the highest percentage of postoperative penile straightening. Overall, the TachoSil graft showed the best performance when preoperative curvature is taken into account. Based on the available literature, BMG appear to be the most effective for penile curvature correction in PD, but this is offset by the requirement for low preoperative curvature. The TachoSil graft shows the best overall performance when preoperative curvature is considered. Comparative randomized clinical trials are still needed to determine graft superiority.

Surgical management of complex curvature in Peyronie's disease

PURPOSE

About 10% of Peyronie's patients are complex cases with severe curvature (>60 degrees), ventral plaque, multiplanar curvature, hour-glass/hinge deformity, notching deformity, and ossified plaque. In patients with complex Peyronie's disease (PD), different techniques (shortening procedures, lengthening procedures, and penile prosthesis implantation (IPP)) may be necessary to achieve successful result. This review aims to analyze the various surgical techniques employed in the management of Peyronie's disease, with a specific focus on patients with complex deformity.

METHODS

Articles focusing on the surgical management of complex curvature in Peyronie's disease were searched in MEDLINE and PubMed published between 1990 and 2023.

RESULTS

Shortening procedures are linked to penile shortening and are not recommended for complex cases such as notching, hour-glass deformity, or ossified plaque. Lengthening procedures are suitable for addressing complex curvatures without erectile dysfunction (ED) and are a more appropriate method for multiplanar curvatures. Penile prosthesis implantation (IPP), with or without additional procedures, is the gold standard for patients with ED and Peyronie's disease. IPP should also be the preferred option for cases of penile instability (hinge deformity) and has shown high satisfaction rates in all complex cases.

CONCLUSION

While surgical interventions for complex curvature in Peyronie's disease carry inherent risks, careful patient selection, meticulous surgical techniques, and post-operative care can help minimize complications and maximize positive outcome.

Experience With Extra-Tunical Grafting and Tunica Albuginea Plication for Correction of Indentation Deformity in Men With Peyronie's Disease

OBJECTIVE

To further evaluate extra-tunical grafting (ETG), a relatively new surgical option to treat corporal indentation in those with Peyronie's disease without buckling or hinge effect, we report our experience, patient satisfaction, and surgical outcomes.

METHODS

Retrospective review of patients following ETG, including pre-operative deformity, type of graft, graft location (under or over Buck fascia), patient characteristics, and satisfaction. Overall cosmetic satisfaction with deformity correction between patients undergoing 2 different ETG locations and 3 different types of grafts, as well as perceived bother of graft visibility and palpability were assessed.

RESULTS

From 2018-2023, 35 patients underwent ETG and tunica albuginea plication (TAP) with 89.6% of patients having persistent correction on office examination at a median (interquartile range) follow-up of 23.5 (15.2) months. Overall satisfaction with penile appearance by grafting location via patient-reported questionnaires showed no statistical difference (P = .47). Patients undergoing TAP and ETG were satisfied with their erect appearance regardless of graft material. Patients reported grafting tissue was palpable (74.3%) and visible (48.6%) in the flaccid state as compared to the erect state (8.6% and 5.7%).

CONCLUSION

ETG presents a less invasive surgical option than traditional approaches to correct indentation deformities not associated with instability. Our experience shows high patient satisfaction rate following correction of indentation using graft tissue when placed under or over Buck fascia. At a median follow-up of almost 2 years, patients had persistent correction, and while some report visibility of the graft and palpability in the flaccid state, this tends to disappear in the erect state.
