Review
INTRODUCTION
Peyronie's disease is a common, benign condition characterized by an acquired penile abnormality due to fibrosis of the tunica albuginea. This may lead to penile curvature, deformity, discomfort, pain, and erectile dysfunction, resulting in emotional and psychosocial effects on patients. Therefore, it is important for urologists to thoroughly evaluate the extent of the patient's bother and discuss treatment goals, therapeutic options, and expectations.
MATERIALS AND METHODS
We provide a review of the current landscape for the diagnosis, management, and treatment of Peyronie's disease, including oral, topical, intralesional, external energy, and surgical therapies.
RESULTS
The hallmark of managing Peyronie's disease is attentive patient counseling. Patients may be hesitant to discuss their symptoms unless inquired directly and may not be aware that treatments exist. It is not uncommon for Peyronie's disease to be diagnosed incidentally during a routine or unrelated healthcare visit, with reported rates of incidental diagnosis as high as 16%. Treatment options are stratified by disease phase which is defined by whether symptoms (e.g. penile deformity and discomfort) are actively changing or have stabilized. Conservative therapy is the most common recommendation during the active phase with more invasive treatments reserved for the passive phase. Conservative therapy may include oral or topical medication, intralesional injection, and external energy therapy. These treatments may also have a role in improving symptoms during the passive phase prior to undergoing more definitive surgical treatment. Surgical interventions include tunical plication, plaque incision or excision with or without grafting, and penile prosthesis implantation. Despite the variety of treatment options available to patients, each has a distinct efficacy and adverse effect profile, warranting thorough discussion to meet patients' goals and manage expectations.
CONCLUSION
Peyronie's disease is a common condition that is underdiagnosed and undertreated. Patients with Peyronie's disease will benefit from a comprehensive evaluation and in-depth counseling so that they may become familiar with the natural disease course and have appropriate expectations of each treatment option.

INTRODUCTION
Although the literature of the positive effects of penile low intensity extracorporeal shockwave therapy is meanwhile substantial, there are substantial differences regarding both the sources of energies and extracorporeal shockwave therapy (ESWT) devices.
OBJECTIVES
To provide an overview on the energy range and energy differences of the 6 currently marketed ESWT devices along with personal ESWT experiences in 350 patients.
METHODS
This review includes all published preclinical and clinical penile ESWT studies with evaluation of the technical differences of the 6 ESWT devices and the personal experiences with these 6 devices in ED and PD. The main outcomes measures were success rates in ED (International Index of Erectile Function-erectile function change, conversion of phosphodiesterase type 5 inhibitors non-responders) and PD (change in deviation and plaque size), differences of used sources of energy, and energy flux densities (EFDs).
RESULTS
3 different sources of energies are used, that is electromagnetic, electrohydraulic, and piezoelectric .The devices markedly distinguish in the available spectrum of the EFD ranging between 0.09 and 0.55 mJ/mm². In terms of the biological effects, the relevant energy parameters are -6 dB and the 5 MPa focus, which differ substantially between the ESWT devices. In addition, a great variability in the treatment protocols and applied energy is obvious. The preliminary own experiences with low intensity extracorporeal shockwave therapy in 160 ED non-responders and 190 patients with PD with success rates of 45% and 47%, respectively, are reported.
CONCLUSION
Positive results were published with all 6 ESWT devices in question in patients with organic ED but with huge differences regarding the EFD and the total energies applied. There is growing evidence that concentrated treatment protocols and increasing energies may yield better results. In this context, it may be argued that at least some of the published studies were markedly underpowered .Owing to the paucity of published studies, the literature of the effects of ESWT in PD and for penile rehabilitation after pelvic surgery is currently not conclusive.

Review
Penile concerns include erectile dysfunction (ED) and Peyronie disease (PD). Restorative therapies including Stem Cell Therapy (SCT) and Platelet Rich Plasma (PRP) injections are proposed to treat these concerns. SCT encompasses the harvesting and injection of mesenchymal stem cells or stromal vascular fractions from various tissue sources. PRP is derived autologously from a patient's plasma and is then injected into the penile tissue. These therapies repair damaged penile tissue and promote both new cellular and vascular growth, as demonstrated in basic science studies. Human trials on SCT and PRP for both ED and PD and have yielded promising results with few side effects. While encouraging, small cohort size and lack of blinding or placebo control limit these studies' external validity. Recently, the first double-blinded randomized controlled trial on PRP for ED was published, providing significant evidence of efficacy. With the rapid commercial availability of SCT and PRP for ED and PD, it is imperative to perform more randomized and placebo-controlled trials with standardized procedures and preparations to evaluate efficacy and safety. This narrative review will summarize the available literature on these penile restorative therapies to date.

OBJECTIVE
To systematically review the literature in order to investigate the efficacy and safety of surgical and non-invasive penile enhancement procedures for aesthetic and therapeutic purposes.
METHODS
A systematic search for papers investigating penile enhancement procedures was performed using the MEDLINE database. Articles published from January 2010 to December 2019, written in English, including >10 cases, and reporting objective length and/or girth outcomes, were included. Studies without primary data and conference abstracts were excluded. The main outcome measure was objective length and/or girth improvement. The review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement.
RESULTS
Out of 220 unique records, a total of 57 were reviewed. Eighteen studies assessed interventions for penile enhancement in 1764 healthy men complaining of small penis. Thirty-nine studies investigated 2587 men with concomitant pathologies consisting mostly of Peyronie's disease and erectile dysfunction. Twenty-five studies evaluated non-invasive interventions and 32 studies assessed surgical interventions, for a total of 2192 and 2159 men, respectively. Non-invasive interventions, including traction therapies and injection of fillers, were safe and mostly efficacious, whereas surgical interventions were associated with minor complications and mostly increased penile dimensions and/or corrected penile curvature. Overall, the quality of studies was low, and standardized criteria to evaluate and report efficacy and safety of procedures, as well as patient satisfaction, were missing.
CONCLUSION
The quality of the studies on penile enhancement procedures published in the last decade is still low. This prevents us from establishing recommendations based on scientific evidence regarding the efficacy and safety of interventions that are performed to increase the penis size for aesthetic or therapeutic indications.

Review
This article reviews the anatomy and magnetic resonance imaging (MRI) appearance of the penis. The recommended technique for MRI of the penis is outlined, with discussion of the benefits and drawbacks to imaging the penis after artificial erection. Common penile pathologies are reviewed, with a summary of their clinical features, MRI appearance, and treatment. The ability to demonstrate the erectile bodies and vasculature helps to evaluate vascular pathologies such as priapism, Mondor disease, and cavernosal thrombosis. MRI is also a useful tool to assess for traumatic abnormalities of the penis, with the depiction of soft tissue anatomy and fascial layers allowing for evaluation of penile fracture and penile contusion. Malignant disease of the penis is also reviewed, including squamous cell carcinoma, urethral carcinoma, metastases, and rare neoplasms. Staging of these neoplasms is addressed, with discussion of how MRI can be used to assess the extent of tumor involvement. MRI also clearly demonstrates the tunica albuginea, which allows for evaluation of Peyronie's disease.

Review
: Peyronie's disease (PD) is a disorder of the tunica albuginea from disordered and excessive deposition of collagen resulting in a palpable scar, pain, erect penile deformity and erectile dysfunction that significantly impacts patients both physically and emotionally.: Several treatment options have been described for PD, including shockwave therapy, traction therapy, both oral and intralesional pharmacological options, and surgery. This review seeks to examine the data for different types of non-surgical treatments for PD. We review how various treatment modalities impact several relevant clinical endpoints for Peyronie's disease, including effects on pain, penile curvature, plaque formation, and erectile function. We performed a literature search using PubMed and SCOPUS while referencing AUA, EAU, and CUA guidelines for management of Peyronie's Disease for studies published 1980-2020.: Intralesional collagenase injections have the strongest evidence and are the only FDA approved intralesional treatment for PD. Penile traction therapy (PTT) is low risk and may be beneficial in patients willing to invest significant time using the devices. Furthermore, oral combination therapy with other modalities may provide some benefit. Further investigation is required to better understand pathophysiology of PD and clarify the therapeutic utility of existing treatments, potentially with a multimodal strategy.
