Introduction: Peyronie’s disease affects three to nine out of 100 men and can have significant emotional and sexual effects on patients and their partners. Treatment options vary but once the disease becomes quiescent they are predominantly surgical. The type of surgery adopted is dependent on the degree of angulation although no single procedure is without its disadvantages. Plication corporoplasty is one approach but patients experience and often complain of loss of penile length. We set out to devise a mathematical model that would allow us to predict the loss of length based on erect penile dimensions. Methods: By considering the bend in the erect penis as an arc, utilising the degree of curvature and the penile circumference at maximum angulation, we have been able to derive a simple equation using parameters that are easily obtained in the clinic. Results: Where L=length lost, C=circumference at point of curvature, Y=angle of curvature as measured by a goniometer: L = CY/180. We have then been able to create a quick reference table based on the average penile circumference (12–13 cm±5 cm). Conclusion: This formula provides a more scientific and accurate means to predict potential loss of penile length in patients undergoing plication corporoplasty. Although we recognise that applying a rigid mathematical model to a biological non-uniform pathology creates inaccuracies this is somewhat better than ‘by sight’ estimates, and will allow more informed counselling and consent for patients. As far as we are aware this is the first attempt to create a mathematical model to aid counselling for plication corporoplasty.

Review Current

Corporoplasty is urological correction surgery for penile deviation that causes copulatory dysfunction or aesthetic discomfort. Penile deviation can be congenital or acquired (Peyronie’s disease, penile fracture). Congenital penile deviation is relatively rare and manifests in the curvature of erect penis ventrally and/or laterally, in most cases. According to many studies, patients with curvatures of 30° or more eventually seek surgical treatment. Congenital curvature may be mistaken for Peyronie’s disease for similar manifestations that, however, differ in aetiology and pathophysiology. Excisional, incisional corporoplasty or plication are commonly engaged to treat congenital curvatures, in various techniques and modifications. Augmentation transplantation (grafting) and penile prosthesis implantation with variant deviation treatment options are the usual practice in Peyronie’s disease. Unequivocal judgment of pros and cons in any particular technique is nevertheless implausible to make. This article aims to review current trends, protocols and their relative advantages in corporoplasty.

Nonsurgical Therapy

The purpose of our study was to outline the evaluation of the Peyronie's disease (PD) patient and review the available nonsurgical treatments. A review of the literature on oral, intralesional, external energy, iontophoresis, and mechanical therapies for PD was performed. PubMed was utilized to find all published articles, and several meeting abstracts were reviewed for data ahead of publication. Our medical evaluation of the PD patient is described. The published results of available treatment options are reviewed, with recommendation by the authors for appropriate nonsurgical management of PD. There are no available validated questionnaires for PD, but a thorough history and focused physical examination, including measurement of erect penile deformity, will help the clinician make the diagnosis and guide treatment options. Although there are many published reports that show efficacy of nonsurgical therapies for PD, there is a lack of large-scale, multicenter, controlled clinical trials, which makes treatment recommendations difficult. Careful review of the literature does suggest that there are treatment options that make scientific sense and appear to stabilize the disease process, reduce deformity, and improve function. Offering no treatment at all will encourage our patients to pursue alternative treatments that may do harm, and misses the opportunity to do some good. Clearly, further work is necessary to develop safe and effective nonsurgical treatments for PD.

State Of Art

In recent years, penile traction therapy (PTT) has gained considerable interest as a novel nonsurgical treatment option for men with Peyronie’s disease (PD) and short penises. The current published literature suggests that selected cases of PD may benefit from a conservative approach with PTT, resulting in increased penile length and reduction of penile deformity. It appears to be safe and well tolerated but requires a great deal of patient compliance and determination. This article reviews the current literature pertaining to the use of PTT in men with PD, short penises and in the setting of pre- and postprosthesis corporal fibrosis.
