Defining predictors of response to intralesional verapamil injection therapy for Peyronie's disease.
ABSTRACT • To assess factors that predict penile curvature responses to intralesional verapamil (ILV) injection therapy for men with Peyronie's disease (PD).
• Men with PD for <1 year were assessed at baseline and after 3 months of bi-monthly ILV-injection therapy. Curvature was assessed at the time of maximum penile rigidity. • Univariate relationships were tested with correlation or chi-square analyses. • Multivariate analyses included logistic and linear regression. • We analysed curvature improvement, defined as a decrease of ≥10 ° from baseline. Additionally, the relationship between curvature outcomes and patient age and degree of baseline penile curvature were assessed.
• Data from 131 men were included and the rates of penile curvature change were:26% improved, 12% worsened, and 62% stable. • Age (r=-0.24, P < 0.01) and larger baseline penile curvature (r= 0.33, P < 0.01) were associated with improved curvature on univariate analysis. • On multivariate analysis (logistic regression), both age [odds ratio (OR) 0.93, P < 0.01, 95%CI 0.89-0.97] and larger baseline penile curvature (OR 1.07, P < 0.01, 95%CI 1.04-1.11) were associated with improvements in curvature after ILV-injection therapy. • Improvements in curvature were associated with age (≤40 years vs >40 years; OR 0.27, P < 0.05, 95%CI 0.10-0.75) and degree of penile curvature at baseline (≤30 ° vs >30 °; OR 9.12, P < 0.01, 95%CI 1.94-42.84) when dichotomized as indicated.
• Younger age and larger baseline penile curvature were predictive of favourable curvature outcomes. • Analysis of dichotomized variables suggests that age and baseline curvature thresholds may be important to consider when deciding on ILV as a therapeutic strategy for PD.

ABSTRACT: Peyronie disease is a common cause of penile deformity and sexual dysfunction. Although surgery is regarded as the definitive management for this condition, there are many medical and minimally invasive therapies available, with widely varying efficacy reported in the literature. The purpose of this review is to describe the current state-of-the-art for each of the most commonly used as well as several developing non-surgical treatments. Further, we hope to offer perspectives that will aid practitioners in deciding among these treatments that are either already in use or have the potential to be used as alternatives to surgery in the management of this frustrating disease.The world journal of men's health. 12/2013; 31(3):183-192.

ABSTRACT: The aim of the current study was to provide an overview about the surgical and medical management of acquired and congenital penile's curvature. A systematic review of the literature was done from the PubMed database by searching the following keywords alone or in combination: Congenital penile curvature; Congenital penile deviation; Acquired penile curvature; Acquired penile deviation; Peyronie's disease. The treatment of congenital curvature is only surgical. The most common technique is the Nesbit's technique which consists in making elliptical excisions of the tunica albuginea. There are also incison or plication procedures which are efficient as well. Acquired curvature is most of the time represented by the Peyronie's disease or is post-traumatic. Among oral treatments available, the Potaba is the only drug which has proved a significant reduction in penile plaque size. Injections of interferon and nicardipine have also shown their efficacy. Ionotophoresis and extracorporeal shock-wave therapy may be beneficial for penile pain. Other therapies (vacuum, traction devices, topical Verapamil) can be interesting but other studies are necessary to recommend them. Surgical treatment is recommended during the fibrotic phase. The most common technique is also the Nesbit's technique. In case of severe curvature (curve superior to 60°), small penis, major deformations, graft techniques can be used. Moreover, if there is a sexual dysfunction, penile prosthesis is recommended. Other studies are necessary to prove the efficacy of most of the drugs already available in the treatment of the penile curvature. It seems to be interesting to combine the different treatments to improve the results of those therapies.Progrès en Urologie 03/2014; 24(3):203-11. · 0.80 Impact Factor
