INTRODUCTION: Over 25% of the more than 725,000 cases of nosocomial infection in the United States are related to an implantable device. Despite the standard typical strategies available, infection rates for breast implants, cerebrospinal shunts, and penile implants remain unacceptably high. This paper will review use of a "no-touch" technique in varied surgical procedures from orthopedic fracture repair, cerebrospinal fluid shunt placement, and breast reconstruction/augmentation to penile prosthesis implantation...

Pomegranate (POM) juice may benefit the erectile process, but the scientific evidence is lacking. This study evaluates the molecular characterisation and confirmation of POM's action on human corpus cavernosum (HCC) obtained from patients (n = 16) undergoing penile prosthesis implantation. After phenylephrine contraction, the relaxant effects of POM with various inhibitors in the presence and absence of palmitic acid (PA)-induced acute oxidative stress were investigated. Electrical field stimulation (EFS)- and acetylcholine (ACh)-induced relaxation were performed using organ bath preparation...

OBJECTIVES: Patients who are not responding to injectable and/or vacuum oral pharmacological treatments can receive a penile prosthesis. Three types of penile prostheses are used in France: rigid, semi-rigid and inflatable prostheses 3-piece or 2-piece. We have assessed the National surgical insertion practices between 2006 and 2013 (number of prostheses insertions, types, procedure locations, number of surgeons and distribution [public or private sectors]). MATERIALS AND METHODS: Data analysis from the French Technical Agency of Information on Hospitals (ATIH) (2006-2013) using the common classification of medical acts (CCAM) and after code extractions related to this surgery (JHLA002, JHLA003, JHLA004)...

A 75-year-old male had failed to respond conservative therapy for erectile dysfunction and had undergone insertion of a malleable penile prosthesis in 1995. Twenty years after the initial implant he presented with right-sided prosthesis localized in the buttock. There was no infection. The prosthesis was extracted through an incision in the right hip. As in the recent case, mechanical failures in malleable penile prosthesis models, can occur. Penile implant migration back to the buttock without a curve deformity is an extremely rare complication...

In the current era of the early diagnosis of prostate cancer (PCa) and the development of minimally invasive surgical techniques, erectile dysfunction (ED) represents an important issue, with up to 68% of patients who undergo radical prostatectomy (RP) complaining of postoperative erectile function (EF) impairment. In this context, it is crucial to comprehensively consider all factors possibly associated with the prevention of post-RP ED throughout the entire clinical management of PCa patients. A careful assessment of both oncological and functional baseline characteristics should be carried out for each patient preoperatively...

BACKGROUND: The 3-piece inflatable penile prosthesis was introduced in 1973 as a treatment for men with erectile dysfunction. Consisting of 2 corporal cylinders, 1 pump, and a fluid-filled reservoir, the prosthesis is placed by blunt dissection into the retropubic space. The dissection for the reservoir is performed blindly into a space juxtaposed with nerves, vessels, and the bladder. OBJECTIVE: To propose a novel approach for inflatable penile prosthesis reservoir placement involving gentle dilation of the retropubic space using a Foley catheter balloon...

The malleable prosthetic implant is widely accepted among patients and physicians owing to a lower degree of surgical complexity, its rare mechanic failures and lower cost. We have compared the degree of satisfaction with malleable prosthetic implant in 60 patients, 36 with Spectra (AMS) and 24 with Genesis (Coloplast). For assessment purposes, we implemented the Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS) satisfaction questionnaire adapted for penile prosthetic implants. The mean age and follow-up was 61...

REVIEW
Veronika K Jaeger, Ulrich A Walker
Erectile dysfunction (ED) is a major issue in systemic sclerosis (SSc) as it is observed in around 80 to 90 % of men with this connective tissue disease. ED greatly impacts the quality of life and should be actively addressed as a common complication. Whereas ED in the general population is usually associated with risk factors for atherosclerosis as well as cardiovascular disease, the main aetiology of ED in SSc is microangiopathic. In SSc, the blood flow is reduced in the small penile arteries due to corporal fibrosis and myointimal proliferation...
