Abstract

BACKGROUND: Peyronie's disease (PD) is a challenging clinical entity. To assist clinicians with diagnosis and management, four separate organizations have published PD guidelines over the past five years, but there remains a lack of consensus and data-driven recommendations for many aspects of diagnosis and treatment. AIM: To compare and contrast PD guidelines, highlighting key similarities and differences among the guideline panel recommendations and identify areas for further research. METHODS: We performed an extensive review to compare and contrast diagnosis and treatment recommendations from publically available published PD guidelines from four different organizations: American Urological Association, European Association of Urology, Canadian Urologic Association, and the International Society of Sexual Medicine. OUTCOMES: Key similarities and differences with regards to definition, evaluation, nonsurgical and surgical treatments were compared. RESULTS: Points of general consensus among the guideline panels included: History is adequate for diagnosis of PD, and intracavernosal injection is a gold standard to evaluate penile deformity prior to invasive intervention. Careful counseling with shared decision-making is required prior to treatment. In general, plication and incision and/or grafting surgery is reserved for patients with preserved erectile function whereas penile prosthesis implantation is the only surgical option for PD patients with erectile dysfunction. Overall, nonsurgical treatments have inferior evidence of efficacy with these being the main area of controversy; however, all societies recognize that intralesional injections may be used. 0Further research into the pathophysiology of PD may direct novel treatments targeted towards early intervention and rigorous outcomes research may direct best practices for the surgical treatment of PD in the future. CLINICAL IMPLICATIONS: PD is a challenging clinical entity. Direct comparison of the published PD guidelines highlights clear standards of care as well as areas where more research is needed to promote higher levels of evidence-based practice. STRENGTHS & LIMITATIONS: To our knowledge this is the first report to directly compare and contrast published guidelines pertaining to the diagnosis and management of PD. Limitations include the lack of evidence-quality review pertaining to individual guideline recommendations, although this was not the aim of this review. CONCLUSION: We highlight consensus of major urologic societies on many aspects of work up and management of PD with notable exceptions which may guide further research.

    Guidelines differ on how many months after symptom onset define stable disease, from six months in CUA and ISSM to more than 12 months in AUA.

    “In contrast, there is discrepancy regarding the number of months since symptom onset that defines stable disease, ranging from six-months (CUA, ISSM) to greater than 12-months (AUA).1, 26, 28”

      The AUA guideline’s “Active vs. Stable Disease” section defines stable disease as symptoms clinically unchanged for at least three months; it does not define it as more than 12 months since symptom onset. The >12-month duration in the Treatment section is an eligibility criterion for an interferon trial, not the guideline’s definition of stable disease. No page numbers are provided in our copy.

    The lack of consensus on stability duration underscores heterogeneity in urology patient populations and supports the need for a standardized definition for consistent results reporting in future intervention studies.

    “This lack of consensus underscores the heterogeneity in patient populations that is routinely seen within the urology literature, and supports the need for a more standardized definition to ensure consistent results reporting with subsequent intervention studies.”

  • The paper relies on this without support.

    Recommendations from the different guidelines can be meaningfully compared despite their different grading systems and terminology.

    “Each of the four guidelines were independently reviewed by three authors (MGM, LAW, MJZ) and pertinent data abstracted for comparison between guidelines.”
  • The paper relies on this without support.

    PD is benign.

    “and given the benign nature observation alone is an appropriate treatment decision when made by the adequately informed patient.”

    The bulk of the available Peyronie's disease literature has methodological and statistical flaws, poor study design, and inadequate power to assess treatment effect.

    “Moreover, the bulk of the available literature suffers from methodologic and statistical flaws with poor study design and inadequate power to assess treatment effect.”
  • The paper relies on this without support.

    Much of the data used to counsel Peyronie's disease patients comes from very low-level evidence, such as retrospective single-surgeon or single-center cohorts with limited follow-up and no controls.

    “Much of the data that we use to counsel our patients is based on very low-level evidence such as retrospective, single-surgeon or single-center cohorts with limited follow-up and absent controls.”
  • The paper relies on this without support.

    There is a paucity of rigorous, multi-center, long-term outcomes data comparing Peyronie's disease treatment strategies.

    “there is a paucity of rigorous, multi-center, and long term outcomes data comparing treatment strategies.”
  • The paper relies on this without support.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Claims read under definition version 3 (extract-v3) on 2026-09-28.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-09-28.

Cited sources are checked by gpt-6-sol.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
