Surgical Management of Peyronie’s Disease

Assessment of Conservative Combination Therapies for Active and Stable Peyronie's Disease: A Systematic Review and Meta-analysis

CONTEXT

In patients with Peyronie's disease (PD), oral, injected, or topical agents provide limited efficacy. In this setting, combination of two or more conservative treatments may improve symptoms further.

OBJECTIVE

To explore the effects of available conservative combination therapies for active and stable PD through a systematic review and meta-analysis.

EVIDENCE ACQUISITION

We searched multiple databases and sources of gray literature until June 2021. We included randomized or observational comparative studies assessing any conservative combination therapies for PD. We undertook a random-effect meta-analysis when at least two studies employed the same treatment modality (PROSPERO: CRD42021224517).

EVIDENCE SYNTHESIS

Overall, 13 studies on active PD and ten on stable PD (1962 participants) were included. Most included studies raised methodological concerns. In patients with active or stable PD, the available evidence is inconclusive to support the use of any combination treatment modality, such as intralesional verapamil injections, antioxidants, and other oral, injected, or topical agents. Based on data availability, we performed a meta-analysis to compare the effect of collagenase Clostridium histolyticum (CCH) plus adjunctive mechanical therapies (penile traction or vacuum pump) versus CCH monotherapy on penile curvature and length in patients with stable PD. CCH and adjunctive mechanical therapies resulted in an additional decrease of 0.3° in penile curvature (95% confidence interval [CI]: -3.97 to 4.49, I² = 0%) and in an increase of 0.5 cm in penile length (95% CI: -0.32 to 1.4, I² = 70%) compared with CCH monotherapy.

CONCLUSIONS

The available combination treatment modalities, including the addition of adjunctive mechanical therapies to CCH, do not improve symptoms further compared with monotherapy and should not be implemented in patients with active or stable PD. Further high-quality randomized trials combining only recommended treatments are mandatory.

PATIENT SUMMARY

Despite the interest in and optimism for combination treatment modalities, the road to an effective conservative therapy for Peyronie's disease still seems long.

Patient Attitudes Towards Surgical Management of Peyronie's Disease Prior to Men's Health Consultation

OBJECTIVE

To evaluate clinical characteristics associated with patient attitudes toward surgical treatment of Peyronie's disease (PD) prior to consultation in a high-volume male sexual health clinic.

METHODS

From 2014-2018 a prospective database was created of patients presenting to the sexual health clinic at our institution. Multivariable regression analysis was conducted to determine factors associated with pre-visit consideration of surgery.

RESULTS

Of 1359 men presenting to clinic, 342 had a chief complaint of PD. Prior to consultation, 79% of patients (n = 270) stated they were willing to consider surgery to correct their PD symptoms. Factors associated with consideration of surgery included younger patient age (mean 55.8 vs 60.0 years; P = .008), history of depression/anxiety (21% vs 8%, P = .01), greater penile curvature (43.3 vs 34.6 degrees; P = .002), penile shortening (64% vs 44%; P = .003), pain with erections (46% vs 33%; P = .05) and decreased ability to have penetrative intercourse (51.9% vs 65.3%, P = .04). On multivariable analysis, age, history of depression, penile shortening, and mean curvature remained significantly associated. Symptom duration and relationship factors were not associated with a difference in the stated preference to consider surgery prior to consultation (P >.05 for all).

CONCLUSION

Nearly 4 out of 5 patients reported willingness to consider surgical intervention for their PD-related symptoms prior to urologic consultation. On multivariable analysis, younger age, history of depression/anxiety, penile shortening, and curvature were associated with a greater likelihood of considering surgery. This information provides important insight into patient attitude toward undergoing surgery and will help drive patient counseling for men with PD.
