A Contemporary Evaluation of Peyronie's Disease During Penile Prosthesis Placement: MOST, MUST, and More.

PURPOSE OF REVIEW: The use of penile implant for the treatment of both erectile dysfunction and Peyronie's disease has changed little in the last 40 years, primarily limited to modeling and plaque incision. In the current review, I explore the history of Peyronie's treatment at the time of penile prosthesis placement and explore new surgical options that help resolve several of the issues that were not treated with the traditional approaches. RECENT FINDINGS: Advancements have been made in the area of graft material, lengthening procedures, and transcorporal techniques. The goal of these operations is not only to correct curvature, but also to restore length. Not surprisingly, the more complex and aggressive the attempt to correct the curvature, the more complications are possible. While modeling has a low rate of urethral injury, complex lengthening procedure with neurovascular bundle and urethral mobilization may lead to the dreaded complication of glans necrosis. Meanwhile, transcorporal techniques seem to offer a more modest improvement for length and curvature restoration with fewer risks than those seen in more aggressive lengthening procedures. The main limitation to the historical treatment of Peyronie's disease during penile prosthesis, modeling, and plaque incision is there is often no resolution to the penile length-as the maneuvers are made after the implant is already in place. Newer lengthening procedures are promising, however carry increased risks and complexity.

A Surgeon's Guide to the Various Antibiotic Dips Available During Penile Prosthesis Implantation.

PURPOSE OF REVIEW: Inflatable penile prosthesis (IPP) is a treatment for erectile dysfunction. IPPs have undergone improvements; however, post-surgical infections still occur. Furthermore, the type of pathogens infecting the implants has changed recently from Gram-positive to Gram-negative bacteria and fungi due to advances in antibiotic dips targeting the skin flora. To protect against infection, the AMS 700 is pre-coated with InhibiZone (mixture of Rifampin/Minocycline) and the Coloplast Titan, with several antibiotic dip options of differing efficacies. This review discusses strategies to decrease the infection rates in implant surgery, focusing on antibiotic dips. RECENT FINDINGS: Current research endorses the use of rifampin/gentamicin as the most studied combination; however, some studies have utilized different dips for additional coverage including the InhibiZone on the AMS 700. With the increasing prevalence of diabetes and Gram-negative organisms, there is a need to develop strategies for increased coverage against infections. Controlled studies with different antibiotic combinations are needed to identify the ideal cocktail to decrease infection.

The Evolution and Utility of the Small-Carrion Prosthesis, Its Impact, and Progression to the Modern-Day Malleable Penile Prosthesis.

INTRODUCTION: Erectile dysfunction has plagued humanity for millennia. For years, treatment had been in the hands of mental health professionals. It was not until the 1970s that urologists created a modality that was marketable, reproducible, and consistently successful at treating impotence, the Small-Carrion Penile Prosthesis. AIM: We present the evolution of the malleable/semi-rigid penile prosthesis, concentrating our efforts reviewing and critiquing the pivotal article published by Drs. Michael P. Small, Hernan M. Carrion, and Julian A. Gordon. We then discuss its continued advancement, current-day utilization, and the future of the malleable prosthesis. METHODS: From the early 1900s, surgeons have been toying with the idea of creating a penile implant. These initial attempts utilized rib cartilage, and eventually synthetic materials, including acrylic, silicone, and polyethylene. RESULTS: In 1975, Drs. Carrion and Small presented their initial experience of 31 patients utilizing their silicone implant. In their manuscript titled, "The Small-Carrion Penile Prosthesis: New Implant for the Management of Impotence," they discuss their technique, perioperative management of complications, and results. CONCLUSIONS: The malleable penile prosthesis continued to evolve throughout the years to the current day Genesis and Spectra. Although the current market is dominated by the inflatable penile prosthesis, there are specific situations where the malleable is ideally utilized. The pivotal article by Drs. Carrion and Small helped pave the way for the "New Era" of penile prosthetics and still remains one of the most impactful contributions to the management of erectile dysfunction.
