RESUMO
Peyronie's disease is a common condition resulting in penile deformity, psychological bother, and sexual dysfunction. Erectile dysfunction is one common comorbid condition seen in men with Peyronie's disease, and its presence significantly impacts treatment considerations. In a man with Peyronie's disease and significant erectile dysfunction who desires the most reliable treatment, penile prosthesis placement should be strongly considered. In some instances, such as those patients with relatively mild curvature, prosthesis placement alone may result in adequate straightening. However, many patients will require additional straightening maneuvers such as manual modeling, penile plication, and tunica albuginea incision with or without grafting. For patients with severe penile shortening, penile length restoration techniques may also be considered. Herein, we provide a comprehensive clinical review of penile prosthesis placement in men with Peyronie's disease. Specifically, we discuss preoperative indications, intraoperative considerations, adjunctive straightening maneuvers, and postoperative outcomes.

The opioid epidemic continues to be a serious public health concern. Many have pointed to prescription drug misuse as a nidus for patients to become addicted to opioids and as such, urologists and other surgical subspecialists must critically define optimal pain management for the various procedures performed within their respective disciplines. Controlling pain following penile prosthesis implantation remains a unique challenge for urologists, given the increased pain patients commonly experience in the postoperative setting. Although most of the existing urological literature focuses on interventions performed in the operating room, there are many studies that examine the role of preoperative adjunctive pain medicine in diminishing postoperative narcotic requirements. There are relatively few studies looking at postoperative strategies for managing pain in prosthetic surgery with follow-up past the immediate hospitalization. This review assess the various strategies employed for managing pain following penile implantation through the lens of the current state of the opioid crisis, thus examining how urologists can responsibly treat pain without contributing to the growing threat of opioid addiction.

Inflatable penile prostheses are an important tool in the treatment of medically refractory erectile dysfunction. One of the major complications associated with these prostheses is infections, which ultimately require device explanation and placement of a new device. Over the past several decades, significant work has been done to reduce infection rates and optimize treatment strategies to reduce patient morbidity. This article reviews the current state of knowledge surrounding penile prosthesis infections, with attention to the evidence for methods to prevent infection and best practices for device reimplantation.

Penile prosthesis implantation is the gold standard of surgical therapy for patients with medication-refractory erectile dysfunction. However, this umbrella definition includes significant heterogeneity and associated risk profiles that should be candidly discussed and addressed perioperatively. Factors associated with operative success and patient satisfaction are often surgery specific; however, risk profiling via patient selection, preoperative optimization, proper device selection, and intraoperative consideration are highly correlated. Some examples of common risk profiles include comorbidity(ies) such as cardiovascular disease, diabetes mellitus, prior abdominal surgery, Peyronie's disease, and psychological risk factors. Similarly, integration of surgeon- and patient-amenable characteristics is key to decreasing risk of infection, complication, and need for revision. Finally, patient risk profiling provides a unique context for proper device selection and evidence-based intraoperative considerations.

The field of prosthetic urology demonstrates the striking impact that simple devices can have on quality of life. Penile prosthesis and artificial urinary sphincter implantation are the cornerstone procedures on which this specialty focuses. Modern research largely concentrates on decreasing the rates of complication and infection, as the current devices offer superior rates of satisfaction when revision is not necessary. These techniques are also able to salvage sexual function and continence in more difficult patient populations including female-to-male transgender individuals, those with ischemic priapism, and those with erectile dysfunction and incontinence secondary to prostatectomy. This review summarizes modern techniques, outcomes, and complications in the field of prosthetic urology.

ABSTRACT Purpose We present a novel AUS implantation technique using a single perineal incision for single device placement or in combination with an inflatable penile prosthesis (IPP). Urinary and sexual dysfunction following the management of prostate cancer has a significant impact on the quality of life of our patients. While there are marginal changes in the prosthetic devices, we strive to reduce post-operative morbidity while maximizing efficacy. Materials and Methods We retrospectively reviewed the outcomes of 6 patients who underwent single perineal incision placement of a virgin AUS in 2014, 3 with simultaneous IPP placement. In all cases, the pressure regulating balloons (PRB) were placed in a high sub-muscular ectopic position and the pumps were placed into a sub-dartos pouch through the perineal incision, which was also validated using a cadaveric model. Results The mean patient age was 61 (SD, 7.5 years) with mean body mass index of 31 (SD, 5.9). The average pre-operative pad usage was 7.7 (SD 1.63) pads per day. The mean follow-up was 13.9 months (SD 9.45). Four out of the six patients reported utilizing ≤1 pad daily at follow-up. The one patient who was not initially dry required downsizing of his cuff to 3.5cm; the remaining patient was lost to follow-up. There were no identifiable perioperative or post-operative complications. Conclusions We present our initial report of using a single perineal incision for AUS implantation with a validated sub-dartos pump location, which is safe and effective for implantation of an AUS as a single or double implantation in well-selected patients.

A circumcising incision to deglove the penis for penile prosthesis (PP) implantation can increase the risk of ischemic injury to the glans penis. In order to avoid vascular complications, we describe a novel technique utilizing a ventral incision to perform the PP implantation and a double-dorsal patch graft, or “sliding technique” (ST), in patients with severe Peyronie's disease (PD). Three patients with severe PD and erectile dysfunction at our institution underwent ST and PP implantation through a ventral incision. This new approach was not only successful in facilitating the ST and PP implantation in these patients but also allowed for adequate exposure of the penile shaft with no reported loss of sensation. We also conducted a review of current literature regarding the approaches for PD. While ischemic complications of PP implantation and ST are rare, there are reports of ischemic injury in patients undergoing a circumcising incision. The combination of a circumcising incision and a patient's underlying peripheral artery disease potentially raises a patient's risk of this rare complication. Our innovative ventral incision provides an alternative method for PP implantation and ST in order to avoid ischemia of the penis, while still allowing for adequate exposure.

Penile prostheses are subject to a continuous development and have gained better mechanical reliability and safety during the last decades. In this study, we aimed to investigate the outcomes and satisfaction rates of inflatable penile prosthesis (IPP) and semirigid penile prosthesis (SPP) implantation.
From August 2001 to June 2012, 257 men with erectile dysfunction (ED) underwent penile prosthesis implantation (PPI) at our institution. Of the 257 patients, 118 underwent implantation of IPP and 139 underwent SPP implantation. The pre-operative and post-operative erectile status of the patients were assessed by international index of erectile function (IIEF) questionnaire. The satisfaction of patients and partners were evaluated by a telephone interview using the erectile dysfunction inventory of treatment satisfaction (EDITS) questionnaire and EDITS partner survey.
The overall major complication rate was higher in IPP group. PPI led to a significant improvement in IIEF scores in both groups. For IPP and SPP groups the average EDITS scores were 78±11and 57±8, respectively, and that for the partners were 72±10 and 49±7, respectively (p<0.05).
Although the IPP implantation have better satisfaction rates, the SPP implantation is still a viable treatment option in the surgical treatment of ED because of low cost and high durability with acceptable satisfaction rates.

Penile implant usage dates to the 16th century yet penile implants to treat erectile dysfunction did not occur until nearly four centuries later. The modern era of penile implants has progressed rapidly over the past 50 years as physicians' knowledge of effective materials for penile prostheses and surgical techniques has improved. Herein, we describe the history of penile prosthetics and the constant quest to improve the technology. Elements of the design from the first inflatable penile prosthesis by Scott and colleagues and the Small-Carrion malleable penile prosthesis are still found in present iterations of these devices. While there have been significant improvements in penile prosthesis design, the promise of an ideal prosthetic device remains elusive. As other erectile dysfunction therapies emerge, penile prostheses will have to continue to demonstrate a competitive advantage. A particular strength of penile prostheses is their efficacy regardless of etiology, thus allowing treatment of even the most refractory cases.

PURPOSE: Today, we find that the implant of malleable prostheses still plays a leading role in the surgical treatment of erectile dysfunction. These may involve patients for which the cosmetic advantages of inflatable devices are not as important as low cost, the easier use and less incidence of mechanical complications in the malleable implants. This paper demonstrates infrapubic approach as a technical option for this kind of implant. SURGICAL TECHNIQUE: It offers technical resources and emphasizes the facility in using the method, reducing cutaneous exposure, which diminishes risks of contamination. COMMENTS: As occurs in inflatable implants, when implanting malleable prostheses through the infrapubic access, care must also be taken regarding the possibility of lesion to the vascular-nervous bundle. On the other hand, the approach through the dorsal surface of the corpora cavernosa has a natural capacity for anatomical protection of the urethra, not requiring transurethral catheterization. This benefit is of the utmost importance when considering possible causes of per and postoperative morbidity. Accordingly, we can consider that the infrapubic approach is an effective method and prevails as a technical option for implanting malleable prostheses.

PURPOSE: We performed a retrospective study to analyze the effectiveness of implantable penile prostheses in the treatment of erectile dysfunction. MATERIALS AND METHODS: This study included 249 patients who received implants between 2001 and 2008. A total of 139 patients who underwent penile prosthesis implantation were interviewed. RESULTS: Approximately half of patients had previously used oral drugs before implantation of the prosthesis. About 45 percent had diabetes, 25.9 percent had previously undergone radical prostatectomy (RP), and 64 percent had hypertension. Exchange was performed in 5.7 percent for fracture, inadequate size, or extrusion. A total of 24.5 percent of men had immediate postoperative pain, 7.9 percent had local infection, and 8.6 percent had other complications. Patients who had previously undergone RP were 3.2 times more likely to experience a postoperative complication than patients who had not (p = 0.061). Eighty-nine (64 percent) patients returned to having sex as they had before being diagnosed with ED. Ninety-two of the men (66.2 percent) had sexual intercourse one to two times per week. One hundred twenty patients (86.3 percent) rated their level of satisfaction as good, excellent or very good, which was similar to the percentage of partners. The mean follow-up was 40 months. CONCLUSION: Higher rates of postoperative infections and mechanical problems with the implant were found in this study as compared to other studies, which was probably associated with the relative lack of experience of the trainees who were performing the surgeries. Patients with a history of RP or diabetes mellitus prior to implantation were at higher risk of postoperative complications.

Dezoito novilhos de diferentes raças, com idade de 18-24 meses foram submetidos a remoção do ligamento apical para ocasionar desvio de pênis. Decorridos 60 dias os animais foram colocados em presença de fêmeas em estro, sendo verificado desvio ventral e lateral direito do pênis, com incapacitade de cópula. Os animais foram submetidos ao transplante autólgo de um segmento da cartilagem do pavilhão auricular, sobre a túnica albugínea, substituindo o ligamento apical do pênis removido. Os bovinos quando em presença de fêmeas em estro não apresentaram desvio de pênis e alteração do comportamento sexual. Notou-se a presença de poucas células mononucleares, polimorfonucleares e células gigantes e formação de tecido conjuntivo fibroso, ocasionando aderências resistentes e capacidade de sustentar a extremidade livre do pênis. O método cirúrgico mostrou-se eficiente para corrigir desvios ventral e lateral de pênis de bovinos.
Eighteen 18 to 24-month-old mixed breed bullocks were submitted to removal of the apical ligament of the penis to induce penile deviation. After 60 days from the surgery the steers were put together with cows in heat. A ventral and right lateral penis deviation leading to incapacity to copulate was observed. The bullocks were then submitted to an autolgous transplant of a cartilage segment from the ear pinna placed on top of the tunica albuginea, replacing the penile ligament apical tha had been removed. The implanted material was well tolerated; histologically with only infiltration few mononuclear cells, polymorpho nucleated cells and giant cells, and fibrosis, which caused strong adherence and provided ability to sustain the free penile extremity. The bullocks that were cows in heat did not show any degree of penile deviation nor any change in sexual behavior. The surgical method described here was shown to be satisfactory as to be indicated for correction of ventral and right lateral penile deviation in bullocks.

Purpose: This paper is the first, to our knowledge, to propose the use of a bovine pericardium graft in corporoplasty for penile prosthesis implantation. The advantages of bovine pericardium graft have been demonstrated by its use in cardiac surgery, including low cost, biocompatibility, impermeability, resistance to dilatation, flexibility, low likelihood of retraction, absence of antigenic reaction and natural absorption of the tissue. In this paper, we propose the use of this heterologous material graft in corporoplasty for penile prosthesis implantation. Materials and Methods: Five patients with a history of erosion, infection and fibrosis, mean time of follow-up 32 months (range 9-48 months). Bovine pericardium was used to cover large areas of implanted penile prostheses when use of the tunica albuginea was unfeasible. Results: The surgical procedure resulted in no complications in all patients. Conclusions: Bovine pericardium may substitute synthetic and autologous material with the additional advantages of lower cost and greater availability.

A técnica mostrou ser eficaz, podendo ser indicada para corrigir desvio de pênis ventral e lateral de bovinos.
In this experiment, 18 hybrid steers, from the ages between 16 and 20 months, were submitted to the removal of the penis apical ligament to provoke a penis deviation. After passed 30 days, to be tested, the animals were put together to the females that were in heat. It was verified the formation of the ventral and right lateral penis deviation with incapacity of the copula. The bovines were submitted to the autologous implant from the one following superficial portion tendon from the superficial flexor fingers muscle, on the top of albuginea tunic, replacing the apical penis ligament removed. The material implanted was well tolerated, appearance a few inflammatory cells and formation of the fibrous conjunctive tissue, causing resistant adherence and capacity of sustaining the free penis extremity. The bovines, when were among the females that were in heat, did not show a penis deviation nor sexual behavior modification. The method revealed itself satisfactory and it can be indicated to correct ventral and right lateral penis deviation in bovines.
