[Non-surgical management of Peyronie's disease: State of current knowledge]

Abstract

Background: Peyronie's disease is an inflammatory disorder of the penis, where scar tissue creates a plaque at the level of the albuginea, limits its extension, and leads to a bent and shorter penis during erections. There are no international standards for the evaluation and the treatment of the disease. The aim of this article is to review the current knowledge about the management of Peyronie's disease and to suggest an algorithm to help physicians evaluate and manage this condition.

Material and methods: A literature review was conducted through PubMed database following PRISMA guidelines using the Mesh terms: Peyronie, disease, treatment and diagnosis. Results are presented in a descriptive manner.

Results: Multiple treatment strategies have been proposed, but no conclusive randomized clinical trial is done to assess their efficacies. The oral treatment was shown to be more beneficial in the setting of a multi-modal approach to treat the acute phase. The non-steroidal anti-inflammatories and the potassium para-aminobenzoate are superior to the other molecules of oral therapy for pain management. Local treatment with topical verapamil, iontophoresis and intra-lesional injection of verapamil, interferon alfa-2b and collagenase clostridium histolyticum (CCH) revolutionized the management of the disease by the modification of the plaque size and angulation. Alternative treatments using extra-corporeal shock wave or traction devices are promising. Intra-lesional injection of CCH is the only therapy approved by the Food and Drug Administration for this condition after the stabilization of the disease. The channeling of the plaque before CCH injections is making better results than the initial protocol, concerning angulation improvement.

Conclusion: Multiple therapeutic strategies exist for the management of the Peyronie's disease, but they lack evidence based data. Further randomized clinical trials are needed to evaluate the current practices and to study more efficient treatments.
