Does climate impact inflatable penile prosthesis infection (IPP) risk? Assessment of temperature and dew point on IPP infections.

BACKGROUND: Variations in climate have been associated with a greater risk of surgical site infections, urinary tract infections, and changes in the skin microbiome; however, limited data exist on the impact of climate on inflatable penile prosthesis (IPP) infections. AIM: We sought to evaluate the impact of climate on the risk of IPP infections in a large international, multicenter cohort. METHODS: We performed a multi-institutional, retrospective study of patients undergoing IPP surgery. We then evaluated whether the month or season, during which surgery was performed, affected device infections. Implant infections were defined as infections requiring device explantation. A univariate logistic regression analysis was undertaken. OUTCOMES: Our primary outcome was implant infection. RESULTS: A total of 5289 patients with a mean age of 62.2 ± 10.8 years received IPP placement. There was a fairly even distribution of implants performed in each season. A total of 103 (1.9%) infections were recorded. There were 32 (31.1%) IPP infections in patients who underwent surgery in the summer, followed by 28 (27.2%) in the winter, 26 (25.2%) in the spring, and 17 (16.5%) in the fall. No statistically significant differences were recorded in terms of season (P = .19) and month (P = .29). The mean daily temperature (P = .43), dew point (P = .43), and humidity (P = .92) at the time of IPP placement was not associated with infection. CLINICAL IMPLICATIONS: These findings provide reassurance to prosthetic urologists that infection reduction strategies do not need to be tailored to local climate. STRENGTHS AND LIMITATIONS: Climate data were not directly recorded for each hospital, but rather based on the monthly averages in the city where the surgery was performed. CONCLUSION: The climate at time of IPP placement and time of year of surgery is not associated with IPP infection risk.

Subcoronal Incision for Inflatable Penile Prosthesis Does Not Risk Glans Necrosis.

PURPOSE: Glans vascular compromise had previously been considered a rare but devastating complication of the subcoronal incision for inflatable penile prosthesis surgery. Here, we describe the largest series of subcoronal implants to date to assess contemporary complication rates. MATERIALS AND METHODS: A retrospective review of subcoronal prosthesis placements by a single surgeon from Seoul, South Korea, was performed. Patients were randomly assigned either Coloplast Titan or AMS 700 device per institutional practice. RESULTS: A total of 898 patients who underwent subcoronal implants from May 2015 to March 2022 were analyzed. Median follow-up was 41 months (IQR 40). Preoperative patient comorbidities included diabetes (36.6%) and Peyronie's disease (4%). The most common complication was transient distal penile edema (74.7%). Transient incisional paresthesia (20.6%) was more common in patients with diabetes (31.9% vs 13.9%, P < .01). Five cases (0.5%) of distal penile skin necrosis were reported in patients who had previously been circumcised. Of these, 3 were managed successfully with wet-to-dry dressing, 1 required skin grafting, and 1 required device explant. Device infection without incisional compromise occurred in 2 cases (0.2%). There were no instances of glans necrosis or ischemia observed in this cohort. Of the first-time implants (817, 90.9%), most (62.3%) were successfully completed under local anesthetic alone, with the remainder of surgeries completed with the addition of adjunctive conscious sedation. CONCLUSIONS: Subcoronal incision for first-time or revision penile implant surgery is not a risk factor for glans ischemia or necrosis and can be safely completed under local anesthetic with or without conscious sedation.

Repair of penile prosthesis-induced impending erosion using xenograft during simultaneous inflatable penile prosthesis replacement.

BACKGROUND: Penile prosthesis (PP)-induced impending erosion is a rare complication that has not been well characterized. AIM: This study evaluates the role of prosthesis sizing and of the safety of xenograft windsock repair (AlloDerm, Tutoplast, ArthroFLEX) of impending erosion. METHODS: This was a retrospective review of xenograft use during inflatable penile prosthesis (IPP) replacement. Patient demographics, prior PP characteristics, and xenograft-augmented IPP characteristics were obtained. Paired-samples t tests were used to compare the PP cylinder size, rear tip extender size, and calculated PP length between the most recent prior PP and the xenograft-augmented IPP. Complications and follow-up data were obtained. OUTCOMES: The primary outcome was comparing the corporal body and device measurements between the PP presenting with impending erosion and the implanted xenograft-augmented IPP. The secondary outcome was evaluating the incidence of subsequent explantation. RESULTS: A total of 24 patients underwent xenograft repair with simultaneous IPP replacement from 2012 to 2022. The median number of prior PP was 1 (interquartile range, 1-2.75). The median time between the most recent prior PP and xenograft-augmented IPP placement was 21 (interquartile range, 14-79) months. The prior PP was significantly longer at the time of explantation compared with the measured corporal body length in both the left (21.4 cm vs 20.1 cm; P < .01) and right (21.4 cm vs 20.1 cm; P < .01) sides. However, there was no significant difference in length between the xenograft-augmented IPP length at the time of implantation and measured corporal body length in both the left (20.1 cm vs 20.0 cm; P = .67) and right (20.2 cm vs 20.1 cm; P = .56) sides. A total of 16 (66.7%) cases required bilateral xenograft corporal body use. Only 1 (4.2%) patient had an IPP infection requiring explantation within 90 days of xenograft-augmented IPP placement. A total of 2 (8.3%) patients had device malfunction and 1 (4.2%) patient had impending erosion recurrence requiring removal/replacement of their initial xenograft-augmented IPP in a median time of 56 months from placement. CLINICAL IMPLICATIONS: PP oversizing may increase risk of PP-induced impending erosion, which is a delayed process. STRENGTHS AND LIMITATIONS: This is the largest retrospective study of xenograft use during IPP replacement for impending erosion but does not have a control cohort. This study is limited by its retrospective nature, limited follow-up, and absence of a treatment comparison. CONCLUSION: PP-induced impending erosion may be due to PP oversizing but can be successfully repaired with xenograft windsock during simultaneous IPP replacement.

Delayed placement of an inflatable penile prosthesis is associated with a high complication rate in men with a history of ischemic priapism.

BACKGROUND: Corporal fibrosis is known to result from prolonged priapism; however, the impact of the timing of penile prosthesis placement after priapism on complication rates is poorly understood. AIM: We sought to evaluate the impact of timing of inflatable penile prosthesis (IPP) placement on complications in men with a history of ischemic priapism. METHODS: We performed a multicenter, retrospective cohort study of patients with a history of priapism undergoing IPP placement by 10 experienced implantation surgeons. We defined early placement as ≤6 months from priapism to IPP. We identified a 1:1 propensity-matched group of men without a history of priapism and compared complication rates between men who had early placement, late placement, and no history of priapism. OUTCOMES: Our primary outcome was postoperative noninfectious complications, and secondary outcomes included intraoperative complications and postoperative infection. RESULTS: A total of 124 men were included in the study with a mean age of 50.3 ± 12.7 years. A total of 62 had a history of priapism and 62 were matched control subjects. The median duration of priapism was 37 (range, 3-168) hours and the median time from ischemic priapism to IPP placement was 15 months (range, 3 days to 23 years). Fifteen (24%) men underwent early (≤6 months) IPP placement at a median time of 2 months (range, 3 days to 6 months) following the ischemic priapism event. The remaining 47 (76%) underwent placement >6 months following priapism at a median time of 31.5 months (range, 7 months to 23 years). The complication rate in the delayed placement group was 40.5% compared with 0% in the early placement group and control group. Cylinder-related complications such as migration or leak accounted for 8 (57%) of 14 of the postoperative noninfectious complications. Full-sized cylinders were used in all patients who had a cylinder related complication. CLINICAL IMPLICATIONS: Priapism patients should be referred to prosthetic experts early to decrease complication rates in those needing an IPP. STRENGTHS AND LIMITATIONS: This is a multicenter study from experienced prosthetic urologists but is limited by the retrospective nature and small number of patients in the early placement group. CONCLUSION: IPP complication rates are high in men with a history of ischemic priapism, especially when implantation is delayed beyond 6 months.

Delayed closed-suction drain removal following inflatable penile prosthesis placement: a multi-institutional experience.

BACKGROUND: There are little published data regarding longer percutaneous drain durations following inflatable penile prosthesis placement; despite this, drain proponents suggest reduced scrotal hematoma formation, while detractors cite the risk of retrograde device seeding. AIM: Here, we quantify the outcomes of a multi-institutional cohort with drain durations of 48 hours or greater. METHODS: Data were collected retrospectively for patients undergoing primary 3-piece inflatable penile prosthesis (IPP) placement who had a postoperative drain placed. Cases were performed by 3 surgeons at 3 high-volume centers between January 1, 2020, and March 31, 2022. It was the routine practice of these surgeons to leave percutaneous drains for an interval of 48 hours or greater. R software was used to perform statistical analysis and data visualization. OUTCOMES: Primary outcomes included rates of infection and hematoma formation. Secondary outcomes included device explantation. RESULTS: During the study period, there were 224 patients meeting initial inclusion criteria. Of these, 15 patients had their drains removed before 48 hours, leaving 209 patients for the analysis. Mean drain duration was 67 ± 24.7 hours. The mean follow-up interval was 170 days. Diabetes mellitus was present in 84 (40%) patients with a mean hemoglobin A1c of 7.2%. Penoscrotal and infrapubic approaches were employed (n = 114 [54.5%] vs n = 95 [45.5%]). Reservoir location was split between space of Retzius and high submuscular, with space of Retzius being more common (n = 164 [78.5%] vs n = 45 [21.5%]). Discrete hematomas were observed in 7 patients, with subsequent operative intervention on 2. Notably, both of these were infection cases. There were 3 (1.4%) total device infections. Revision for noninfection causes was required in 9 (4.3%) patients. Fisher's exact testing demonstrated significant association between hematoma formation and anticoagulation and/or antiplatelet therapy (P = .017). On multivariable logistic regression, only anticoagulation and/or antiplatelet therapy remained significant (P = .035). CLINICAL IMPLICATIONS: Maintaining percutaneous closed-suction bulb drains for >48 hours following IPP placement is safe. STRENGTHS AND LIMITATIONS: This multi-institutional study fills a hole in IPP perioperative literature, as there have been no previously published data regarding drain durations >48 hours. The primary limitations are the retrospective nature and lack of a control population. CONCLUSION: Maintaining closed-suction bulb drains for >48 hours following IPP implantation is safe and associated with infection rates comparable to other modern cohorts and a very low rate of hematoma formation.

Penile Prosthesis Placement by a Dedicated Transgender Surgery Unit: A Retrospective Analysis of Complications.

BACKGROUND: Penile prostheses may be used as a component of genital gender affirmation surgery for the purpose of achieving penile rigidity after phalloplasty, and transgender individuals experience higher complication rates than cisgender individuals. AIM: To observe complications with transmasculine penile prosthesis surgery over time and across surgical conditions. METHODS: Retrospective chart review of all transmasculine patients with phalloplasty undergoing penile prosthesis placement between 4/14/2017 and 2/11/2020 (80 patients). OUTCOMES: Independent variables include implant type, previous genital surgeries, and simultaneous genital surgeries. Dependent variables include prosthesis infection and mechanical complication (device malfunction, dislodgement, erosion). RESULTS: There was an overall complication requiring surgery rate of 36% and infection rate of 20% (15/67 for inflatable prostheses and 1/13 for semirigid), with 14% (11/80) experiencing infection requiring removal. Differences in infection rates appeared insignificant across categories of previous surgery or with simultaneous surgery, but we did notice a markedly lower rate for semirigid prostheses compared to inflatable. There was a significant relationship between infection and case number, with the probability of infection decreasing over time. Device loss at 9 months was 21% overall. Preoperative conditions of the neophallus such as prior stricture correction and perioperative factors such as simultaneous clean and clean-contaminated procedures seemed to pose no additional increase in complication rates. CLINICAL IMPLICATIONS: Type and number of prior and simultaneous non-prosthetic surgeries should not be considered as a risk factor for penile prosthesis after phalloplasty for transmasculine patients, even those that are clean-contaminated STRENGTHS & LIMITATIONS: Our cohort size is large compared to currently available studies, although not large enough to generate sufficient power for group comparisons. We have reported every genital surgical step between phalloplasty and penile prosthesis placement and recorded complications with subsequent devices after failure. Patient-reported outcomes were not collected. CONCLUSION: We demonstrate that preoperative conditions of the neophallus, such as prior stricture correction, and perioperative factors, such as simultaneous clean and clean-contaminated procedures, seem to pose no additional increase in complication rates. Our data suggest that surgical experience may further decrease complications over time. B. L. Briles, R. Y. Middleton, K. E. Celtik, et al.

A Rare Cause of Autoinflation after Penile Prosthesis Insertion: Case Series and Systematic Review.

BACKGROUND: In 2016, we reported the first case of high flow priapism and arteriocavernosal fistula caused by penile prosthesis insertion that mimicked device autoinflation. AIM: To raise awareness amongst implanters, we describe further cases from our institution and perform a systematic review of the literature to understand the rarity of this phenomenon. METHODS: Patient demographics, management and outcomes were extracted retrospectively. A systematic search of the EMBASE, PubMed and PubMed Central libraries for studies reporting arteriocavernosal fistula mimicking autoinflation since 1946 was performed. OUTCOMES: To identify and report all known cases of high flow priapism and arteriocavernosal fistula presenting as autoinflation of an inflatable penile prosthesis. RESULTS: Four patients in total (median age 56, range 46-60 years) were identified. Catastrophic bleeding (1.8L) occurred during revision surgery for presumed autoinflation in Patient 1 and subsequent ultrasound (US) confirmed a fistula which was embolized. Patient 2 redeveloped autoinflation following revision surgery. Ultrasound confirmed high flow priapism from an arteriocavernosal fistula. Patient 3 underwent penile magnetic resonance imaging (MRI) to investigate autoinflation and residual penile curvature. MRI showed a tumescent penis despite a deflated device and the fistula was embolized successfully. Patient 4 with sleep-related painful erections did not improve following insertion of penile prosthesis. Doppler US identified 2 fistulae that was embolized but with no resolution of symptoms. Subsequent embolization of both common penile arteries were done to control his symptoms. No other publications apart from the published abstract from 2016 reporting patient 1 was found. CLINICAL IMPLICATIONS: If considered prior to revision surgery, the fistula can be managed safely by minimally invasive percutaneous angioembolisation avoiding surgery which can potentially be associated with significant complications. STRENGTHS AND LIMITATIONS: The rarity of this phenomenon was supported by a systematic review. Our study however does present the findings from a small number of patients. CONCLUSION: Damage to the cavernosal artery during inflatable penile prosthesis insertion can create an arteriocavernosal fistula that mimics autoinflation, leading to catastrophic intra-operative bleeding or unnecessary surgery.

Prevention of Penile Prosthesis Infection.

INTRODUCTION: Management protocols for treatment of severe erectile dysfunction have changed little in the last 20 years. Most algorithms consider penile prostheses as the last option of treatment in patients who have failed medical management. Despite multiple advances in current devices, prosthetic infection remains the most feared complication by implanting surgeons and patients. This report tries to make a compilation of the factors that can be impacted to prevent penile implant infections, and to make penile implantation a safer and more reliable way to solve an erection deficit. PURPOSE OF REVIEW: List events related to the surgical act (pre-operative, intra-operative, and post-operative) that are related to the risk of infection to contextualize possible actions/measures used to avoid prosthetic infection. RECENT FINDINGS: The impact of coated implants on reduction of infection rates. The recommendation to use chlorhexidine-based solutions over iodine solution for preoperative skin preps. Appears to be no difference in infection rates according to the approach chosen by the surgeon (infrapubic vs penoscrotal). The change in the microbial colonies that are colonizing implants in recent years are dramatic. Lack of evidence of which solutions to use for salvage or revision washout surgery: Chemical eradication or mechanical lavage cleansing?. Despite the importance of metabolic control in the literature, there is a disparity in exact glycemic values ​prior to the intervention in our literature. Factors such as preparation of the operative site, presence of comorbidities or previous surgeries, surgical time, or additional maneuvers during surgery can negatively impact the final result of penile prosthetic surgery.

Novel Peyronie's algorithm at the time of penile implant.

INTRODUCTION: Peyronie's disease (PD) is a fibrous transformation of the tunica albuginea within the corpora cavernosa causing curvature of the penis while erect. This cannot only be painful but can also cause narrowing, shortening, an hourglass deformity and problems with penetrative intercourse. There are many means of management of Peyronie's disease at the time of penile implant. Modeling is a commonly used approach but leaves the penis without increased length. Multi-incisional techniques enhance length restoration, but risk significant vascular and neurologic compromise. Herein, we present our experience with a novel algorithm to approach Peyronie's disease with an effort to enhance and restore length without elevation of the neurovascular bundle. MATERIALS AND METHODS: A retrospective review was performed of an institutional review board approved database. Patients treated for Peyronie's disease and erectile dysfunction with penile implant from 8/16/18 to 8/20/2020 were evaluated. RESULTS: In our cohort of 33 patients there is an average of 1.9 cm average stretch difference in stretch penile length before and after management. There was a 2.15 cm difference in the cohort subset that utilized the Brock technique. We had no loss of sensation or glans ischemia. There was one patient with autoinflation. All patients had less than 10 degrees of residual curvature. CONCLUSION: With the proposed algorithm, we are able to safely maximize length restoration without elevation of the neurovascular bundle. More patients with longer follow up is needed to ensure the safety and validity of this algorithm.

[A clinical case of severe vascular complication during implantation of three-piece inflatable penile prosthesis].

Injury of iliac vessels is one of the most disastrous complications of penile prosthesis implantation. There are no detailed descriptions of such cases in world literature. In this article, we present the clinical case of injury to the external iliac vein during the implantation of a three-piece penile prosthesis with particular emphasis on the consequences of such complication in the postoperative period. The article comprises a brief review of the literature on the methods of ectopic placement of the penile prosthesis reservoir.

Management of Disastrous Complications of Penile Implant Surgery.

RATIONALE: Penile Prosthesis Implantation (PPI) is the definitive treatment for Erectile Dysfunction not responsive to conservative management strategies. Furthermore, it is a staple of surgical treatment of severe Peyronie's Disease (PD) and phallic reconstruction. Expert implantologists occasionally face disastrous complications of penile implant surgery which can prove to be very challenging. In this article we present a selected number of case reports which exemplify this kind of situations and discuss management strategies while also commenting on plausible aetiologies. PATIENTS' CONCERNS: The first case describes a PPI performed in end-stage fibrotic corpora after multiple instances of implantation/explant. The second and third cases show two diametrically opposed approaches to the management of glans necrosis after PPI in post-radical cystectomy patients. The fourth case describes the history of a diabetic patient suffering from glandular, corporal and urethral necrosis after a complicated PPI procedure. The fifth case reports the surgical treatment of a case of recurring PD due to severe scarring and shrinking of a vascular Dacron patch applied in a previous operation. DIAGNOSIS: Complication diagnosis in all patient was mainly clinical, intra- and postoperative, with Penile Color Doppler Ultrasonography performed when needed in order to demonstrate penile blood flow. INTERVENTIONS: The patients underwent complex surgical procedures that addressed each specific complication. Complex penile implants with fibrosis-related complications, penile prosthesis explant with and without surgical debridement of necrotic areas, penile prosthesis explant with necrotic penile shaft and urethral amputation with perineostomy, and complex corporoplasty with scar tissue excision and patch application with PPI were performed in the five patients. OUTCOMES: Penile anatomy and erectile function with PPI was achieved in 4 out of 5 patients. 1 of 5 patient is scheduled to undergo a total phallic reconstruction procedure at the time of this writing. LESSONS: Management of disastrous complications of penile implant surgery can be very challenging even in expert hands. In-and-out knowledge of possible PPI and PD complications is required to achieve an acceptable outcome. Bettocchi C, Osmonov D, van Renterghem K, et al. Management of Disastrous Complications of Penile Implant Surgery. J Sex Med 2021;18:1145-1157.

The Association Between Hemoglobin A1c Levels and Inflatable Penile Prosthesis Infection: Analysis of US Insurance Claims Data.

BACKGROUND: The association between elevated hemoglobin A1c (HbA1c) levels and the risk of postoperative infection after penile prosthesis surgery remains controversial. AIM: To examine the association between HbA1c levels and penile implant infections in men undergoing inflatable penile prosthesis (IPP) surgery for erectile dysfunction using a large insurance claims database. METHODS: This was a retrospective review using Optum's de-identified Clinformatics Data Mart Database. Male subjects 18 years and older with available laboratory data undergoing IPP insertion between 2003 and 2018 were included. Administrative diagnosis and procedural codes were used to assess subsequent penile implant revision surgery status for either infectious or noninfectious causes. Associated conditions were controlled for such as smoking status, hyperlipidemia, hypertension, obesity status, and Peyronie's disease. OUTCOMES: The main outcomes were risk of revision for infection and time to revision. RESULTS: A total of 2,363 individuals underwent initial IPP insertion and had available HbA1c data with a mean HbA1c of 6.9%. The overall IPP infection revision rate was 3.9% and the highest rate of 12.1% was seen in the highest HbA1c group (>10%). After adjusting for demographic and health factors, a higher HbA1c level was associated with a higher risk of revision for infection, with every 1 point increase in HbA1c conferring an increased risk of infection requiring revision by 29% (95% CI 17-42%). When infections did occur, they happened sooner in men with HbA1c > 10.0% with an average of 1.3 months vs 3.5 months in the HbA1c < 6.0% group. CLINICAL IMPLICATIONS: These findings provide insight into the potential relationship between HbA1c levels and postoperative risk of infection after penile prosthesis surgery and may aid in clinical decision-making. STRENGTHS AND LIMITATIONS: Strengths include the large sample size, length of data coverage, and real-world analysis of surgeries done across the United States. Limitations include the reliance on insurance claims data, the retrospective study design, and lack of additional relevant clinical variables that may impact infection rates. CONCLUSIONS: While the overall risk of penile prosthesis infection remains modest, the current report notes an increased risk of infection for diabetic men with poor glycemic control.

"Pumpology": the Realistic Issues Associated with Pump Placement in Prosthetic Surgery.

PURPOSE OF REVIEW: The goal of this paper was to discuss the issues and/or overt complications associated with the 3-piece inflatable penile prosthesis (3-IPP) pump. We also addressed how to resolve such issues with or without surgical intervention. RECENT FINDINGS: Numerous modifications of the 3-IPP pump have been introduced with multiple techniques to place the pump. These are largely dependent on the approach to place the 3-IPP. Pump issues may inevitably occur, and there are numerous special maneuvers that can be performed to resolve pump issues. It is important for urologists to know maneuvers for pump malfunctions to prevent unnecessary surgical procedures and pump revision. Several studies are reviewed regarding pump issues and patient satisfaction; however, a more structured prospective research project is warranted to further evaluate these issues.

Pain Management Strategies in Contemporary Penile Implant Recipients.

PURPOSE OF REVIEW: To review the most recent literature citing opioid-sparing multimodal analgesic strategies used to manage perioperative pain in patients who underwent inflatable penile prosthesis (IPP) surgery and to provide the penile implant surgeon a variety of non-opioid-based pain management strategies for IPP management. RECENT FINDINGS: Interventions performed in the pre-operative, intraoperative, and post-operative arenas have all been shown to effectively lower pain scores and reduce opioid consumption. Certain surgical techniques performed during IPP surgery have helped with post-operative discomfort patients may feel after surgery. Multimodal analgesia (MMA) protocols adopted from other surgical fields and other urologic subspecialties that are implemented in IPP surgery have promising results with regard to post-operative pain control and opioid consumption. Protocols that implement a combination of refined surgical technique and multimodal analgesia offer substantial benefit to patients undergoing IPP surgery. Further work is needed to assess long-term pain control and opioid use in patients that undergo IPP surgery using these innovative strategies.

A Review on Penile Length and Girth Issues in Penile Prosthetic Surgery.

PURPOSE OF REVIEW: The goal of this paper is to understand the reasons behind penile length and girth issues after penile prosthesis surgery and review the literature for current strategies employed to decrease these issues. RECENT FINDINGS: Measurement inconsistencies triggering further studies have shown there is a real loss of penile length and girth after prosthesis surgery. There have been varying hypotheses of why this happens, and numerous approaches have been proposed to help combat this in the preoperative, intraoperative, and postoperative settings. Erectile dysfunction prevalence is expected to increase; therefore it is important for urologists to understand the treatment options, including prosthesis surgery. Numerous techniques have been hypothesized and studied in smaller settings in the preoperative, intraoperative, and postoperative settings with regard to prosthetics surgery. However, larger studies are still needed to confirm these findings in order to help to counsel and educate patients preoperatively in addition to employing tactics to help minimize penile shortening.

State of the Reservoir: Current Concepts of Penile Implant Reservoir Placement and Potential Complications.

PURPOSE OF REVIEW: To discuss mechanical and surgical innovations in inflatable penile prosthesis (IPP) surgery and their implications on reservoir placement and patient outcomes. RECENT FINDINGS: The past decade has seen a new emphasis on optimizing outcomes and minimizing complications associated with IPP reservoirs. Innovations in device design have accordingly yielded safer, more durable IPP outcomes over the past four decades. Modifications in surgical approach for reservoir placement abound for both traditional space of Retzius and ectopic reservoir placement techniques. Surgical and medical history, patient anatomy, and patient preference should all be considered when choosing approach for IPP reservoir placement. Prosthetic urologists should be proficient in multiple approaches to provide the best care to their patients.

Current Status for Semirigid Penile Prosthetic Devices.

PURPOSE OF REVIEW: The goal of this paper was to evaluate the current use of semirigid penile prosthesis (SRPP), surgical techniques for insertion of SRPP, and how to prevent and approach surgical complications. RECENT FINDINGS: SRPP is a valid option for those who are refractory to medical therapy for erectile dysfunction (ED) and even more appropriate for specific subsets of patient populations. It is important for urologists to know which patient population SRPP is preferred for. Several studies have shown good patient outcomes and patient satisfaction with those who underwent SRPP.

Reservoir induced bladder rupture: a complication of inflatable penile prosthesis revision surgery.

Reservoir induced bladder rupture is a rare complication of inflatable penile prosthesis (IPP) revision surgery. Our aim is to review the literature and describe our experience with this complication using two case reports that involved reusing an in-situ reservoir. In each case, an episode of gross hematuria indicated that a bladder rupture had occurred. From our experience, we propose ways to possibly avoid and if necessary, manage this rare complication.

HbA1c over 8.5% is not predictive of increased infection rate following penile prosthesis implant surgery in diabetic patients with erectile dysfunction.

Diabetes mellitus is associated with increased risk of erectile dysfunction. Penile prosthesis implantation is an efficient therapeutic option for erectile dysfunction, but not without risk, as infection remains a prominent concern. This study investigates diabetes mellitus as a risk factor for penile prosthesis implantation infection and the relationship between haemoglobinA1c levels and infection rates. All diabetic patients with erectile dysfunction who underwent penile prosthesis implantation surgery between January 2012 and November 2019 at Hamad Medical Corporation, Qatar, were included in this retrospective observational study. A total of 599 diabetic patients with erectile dysfunction had penile prosthesis implantation. Mean age was 59.69 ± 31.19. Penile prosthesis implantation infection rate was 0.83% (5/599), while the mean haemoglobinA1c level was 7.58 ± 1.45 mmol/l (range: 4.1-12.6). A comparison between diabetic patients with penile prosthesis implantation infection and those without infection revealed no significant difference in the level of haemoglobinA1c between the two groups with mean haemoglobinA1c in patients with infected implants 7.14 and 7.59 for noninfected (p = 0.491). Limitations include retrospective single-centre design and low-infection rates reducing sample number. Penile prosthesis implantation infection rate in a large series of diabetic patients was low with no significant association between haemoglobinA1c level and penile prosthesis implantation infection observed.

Penile prosthesis implantation: A single center 25 years of experience.

OBJECTIVES: We analyzed the long-term results of malleable and inflatable penile prosthesis: the rates of complications, revision surgery and patient satisfaction. MATERIALS AND METHODS: Between January 1996 and December 2020, a total of 138 patients underwent implantation of a malleable or inflatable types penile prosthesis. The data of the patients were derived from the patient files and digital recording system. The patients were contacted face-to-face interaction if possible. If it is not possible, phone connection was made. RESULTS: The median age of patients was 56 (21-83) years. Fourteen (10.2%) 1-piece, 46 (33.3%) 2-piece and 78 (56.5%) 3-piece penile prosthesis were implanted. The mostly used perioperative antibiotic was teicoplanin+amikacin in 107 patients. Total complication rate was 30% (n=42). Prosthesis infection constituted 9% (n=13) of these complications. The total satisfaction rate was 89.1%. There was no correlation between the complications and antibiotic regimen or prosthesis type (P=0.488, P=0.454, respectively). The rate of infection showed a slight increase in 3-piece penile prosthesis without any statistically significance (P=0.633). The patients with complications expressed more dissatisfaction compared to those without complications (P=0.001). CONCLUSIONS: In our series, penile prosthesis implantation seems to be a recommended treatment method with high patient satisfaction in the treatment of refractory erectile dysfunction. LEVEL OF EVIDENCE: 4.
