Penile Plication for Peyronie's Disease: The Iterative 8-Dot Technique.

INTRODUCTION: Penile plication is a minimally invasive and effective technique for managing mild to severe curvature from Peyronie's disease. METHODS: Retrospective chart review of all patients undergoing penile plication for Peyronie's disease by one surgeon at one academic institution from November 2016-December 2020 was conducted. Those occurring during IPP placement were excluded. Technical aspects of surgery were detailed and intraoperative video footage was made to illustrate the technique including papaverine injection, incision and variations, tissue dissection, iterative 8-dot plication with absorbable suture, and post-operative evaluation. Primary outcomes were intra-operative and long-term success. RESULTS: A total of 66 patients were included. Median age was 58 years old (Range 24-73 years old). Average preoperative curvature was 45 degrees (Range 20-90 degrees). Curvature direction included 64% dorsal, 20% dorsolateral, 8% ventral, 5% ventrolateral, 3% lateral. Overall, 55% had complex deformities (biplanar curvature (38%), curvature of >60 degrees (50%), or both (11%)). Hinge effect was present in 14% of patients. Erectile dysfunction was present in 57% of patients. Ventral minimally invasive incisions were most common (64%) followed by circumcising incisions (24%), only 9% of patients had concurrent circumcision. Median number of 8-dot plication sutures used was 3 (Range 1-12). Intraoperative success, defined as completely straight was 97%. The 2 technical failures were directly related to ability to maintain intraoperative erection. Mean follow up was 4.5 months (IQR 1.1-4.2) and 91% of patients reported straight erections at follow up. No patient with hinge effect had a intraoperative failure or recurrence. There were no major complications. Rate of minor complication (superficial dehiscence, hematoma) was 6%. There were no revision plication procedures or patients who proceeded to penile implant surgery. CONCLUSIONS: This iterative approach to penile plication with absorbable suture is an effective, minimally invasive, and reproducible technique for correcting acquired penile curvature.

Factors Impacting Postoperative Opioid Use Among Patients Undergoing Implantation of Inflatable Penile Prosthesis.

BACKGROUND: While there is an increasing burden of chronic postoperative opioid use and opioid abuse in the United States, opioid use following inflatable penile prosthesis (IPP) surgery has not been well described. AIM: Describe postoperative opioid use following IPP surgery. METHODS: Seventy-four consecutive patients undergoing IPP implantation by a single surgeon were enrolled. Self-reported diaries tracked the type and amount of medication taken for 2 weeks following IPP surgery. High opioid consumers were defined as those consuming more than the median amount (10 mg) of opioids during the first 2 weeks postoperatively. Multivariate analyses were performed using stepwise backward elimination. OUTCOMES: Quantification of opioid use postoperatively and factors related to high opioid use. RESULTS: Fifty-six patients were included after 7 were excluded for preoperative opioid use and 11 were excluded for inability to contact. Median age was 67.5. Devices used were Boston Scientific (41, 73%) and Coloplast (15, 27%). All patients received local anesthetic. Most surgeries (44, 79%) were performed as outpatient. Preoperative analgesia with acetaminophen, celecoxib, and pregabalin was administered in 44 (78%), 44 (78%), and 28 (50%) of cases respectively; 32 (57%) of patients received 2 medications, 21 (36%) received three medications. In hospital median morphine equivalents was 7.5 (interquartile range [IQR] 0-7.5). Oxycodone prescribed at discharge was 50 mg (29, 52%), 75 mg (4; 7%), and 100 mg (23; 41%). Median milligrams of oxycodone used was 10 mg (IQR 0-23.5) at 7 days and 10 (IQR 0-37.5) at 14 days postdischarge. On univariate analysis, factors associated with an increased likelihood of high opioid use were morphine equivalents utilized in hospital (odds ratio [OR] 1.13, P < .05) and milligrams oxycodone prescribed at discharge (OR 1.05, P < .001) while patient demographics, procedure characteristics, and analgesic types were not found to be predictive of high opioid use. On multivariate analysis, milligrams oxycodone prescribed at discharge (OR 1.04, P < .005) were associated with an increased likelihood of high opioid use after discharge. CLINICAL IMPLICATIONS: Increased understanding of opioid use after IPP surgery may improve prescribing patterns after discharge. STRENGTHS & LIMITATIONS: This study quantified post discharge opioid use over the first 14 postoperative days. It is limited by single surgeon, small sample size, and retrospective design. CONCLUSION: Provider opioid prescribing patterns were associated with high opioid consumption postoperatively and a substantial amount of opioids prescribed at discharge remain unused by patients, suggesting that we can reduce or replace the amount of opioids that are prescribed.

Orchidopexy and Split-thickness Skin Graft for Scrotal Defects After Necrotizing Fasciitis.

OBJECTIVE: To demonstrate a technique for performing orchidopexy and split-thickness skin graft for patients with deficient scrotal skin after debridement for Fournier's gangrene. This is an alternative strategy to healing by secondary intention, flaps, or testicular thigh pouches. METHODS: Orchidopexy was performed after initial debridement using interrupted Vicryl sutures to bring the testicles and inferior penis together. During this procedure, the testicles and spermatic cord were mobilized, and redundant spermatic cord was coiled under the abdominal wall. Once patients were medically stable with no additional planned debridement, a split-thickness skin graft at a depth of 18/1000 inch and meshed 2:1 was applied to the scrotum. The graft was covered with a bolster dressing that was sutured to the scrotum for 5 to 7 days. An inpatient stay was not required after skin graft and bolster placement. Patients were evaluated for cosmetic appearance, pain, and need for revision. RESULTS: From 2017-2021, 10 patients underwent orchiopexy and split-thickness skin graft to the scrotum. Etiology of Fournier's gangrene included diabetes (5), urethral stricture (2), alcohol abuse (2), unknown (1). Median age was 56 years and median BMI was 30 kg/m2. Median length of stay after orchidopexy and skin graft were 18 and 9 days respectively. At a median follow-up of 8 months, there were no issues with chronic pain, discomfort, or need for further intervention. CONCLUSION: Orchidopexy and split-thickness skin graft to scrotum is a feasible method of scrotal reconstruction that leads to acceptable clinical and cosmetic results, and does not result in prolonged inpatient hospitalization. Future research should focus on long term sexual function and quality of life outcomes.

Systematic Review and Meta-Analysis of Cycling and Erectile Dysfunction.

INTRODUCTION: Conflicting evidence exists on the relationship between bicycle riding and erectile dysfunction (ED). A major limitation to several prior studies is the lack of a validated measure of ED. OBJECTIVE: To assess the relationship between cycling and clinically validated ED based on existing literature. METHODS: We searched several major databases from database inception through 2018 using a variety of search terms relating to "cycling" and "erectile dysfunction." Studies were included if they were written in English, reported original data, compared ED between cyclists and non-cycling controls, and used a validated measure of ED, such as the International Index of Erectile Function or the subset Sexual Health Inventory for Men (SHIM). Age, SHIM score, and comorbidities were extracted for all groups. Primary outcomes for each group were mean SHIM score and presence of ED (SHIM ≤ 21). A generalized linear mixed-effects model was used to fit the collected data for meta-analysis. Main outcome measures were unadjusted odds ratios of ED for cyclists and non-cyclists, mean SHIM score difference between cyclists and noncyclists, and both of these measures adjusted for age and comorbidities. RESULTS: After a systematic evaluation of 843 studies, 6 studies met our inclusion criteria, encompassing 3,330 cyclists and 1,524 non-cycling controls. When comparing cyclists to non-cyclists in an unadjusted analysis, there were no significant differences in the odds of having ED or mean SHIM score. However, when controlling for age and comorbidities, cyclists had significantly higher odds of having ED (odds ratio: 2.00; 95% confidence interval: 1.57, 2.55). CONCLUSIONS: Limited evidence supports a positive correlation between cycling and ED when adjusting for age and several comorbidities. Heterogeneity among studies suggests that further investigation into certain populations of cyclists that may be more vulnerable to ED may be beneficial. Gan ZS, Ehlers ME, Lin FC, et al.

A national cross-sectional survey of financial toxicity among bladder cancer patients.

OBJECTIVE: Financial toxicity (FT) has been defined as the patient-level impact of the costs of cancer care. Our objective was to better characterize FT among bladder cancer patients as well as oncologic, demographic and insurance characteristics related to FT. METHODS: We conducted a cross-sectional survey of the Bladder Cancer Advocacy Network Patient Survey Network using the validated COST (COmprehensive Score for financial Toxicity) questionnaire. Our primary outcome was relative degree of FT, with lower COST scores corresponding to worse FT. Wilcoxon rank sum tests and multiple regression were used to evaluate differences in demographic, diagnostic and treatment characteristics as they related to degree of FT. RESULTS: Among 226 patients, median age was 68 years with 64% male, 83% married, and 49% with Medicare with supplemental insurance. Respondents reported an average of 65 months since diagnosis, with 62% reporting noninvasive disease. Mean COST was 28.4 (range 0-44). On multivariable analysis, patients who were younger, with a household annual income less than $50,000, not retired, or with insurance that was neither Medicare nor employer paid were significantly more likely to have worse FT. A majority of respondents (63.5%) agreed or strongly agreed that they would be interested in discussing cost in the context of their treatment preferences, independent of COST score (P = 0.24). CONCLUSIONS: A national cross-sectional survey demonstrated high prevalence of FT which was worse among younger patients with lower incomes, not retired, and without employer-paid or Medicare insurance. Most patients preferred to discuss treatment costs with their bladder cancer provider.

Challenging Ethical Scenarios in the Surgical Treatment of Erectile Dysfunction: A Survey of High-Volume Penile Prosthesis Surgeons.

OBJECTIVE: To investigate how surgeons approach ethically challenging scenarios that arise in penile prosthesis surgery and identify patient-related factors that impact their approach. METHODS: A survey was distributed to the Society for Urologic Prosthetic Surgeons membership consisting of 6 ethically challenging scenarios: an HIV+ patient, a patient with cognitive disability, a registered sex offender, a nonverbal patient, a litigious patient, and an uncontrolled diabetic patient whose insurance will lapse soon. Additional clinical information was provided to assess how the likelihood to offer surgery might change. The primary outcome was the likelihood of offering surgery in each scenario. RESULTS: The response rate was 15.6% (n = 29). When compared to the baseline patient, respondents had a lower likelihood of offering surgery in all scenarios except the HIV+ patient, with the lowest likelihood of offering surgery to a sex offender (P < .01). Within each scenario, factors associated with an increased odds of offering surgery included knowledge that a patient with Down Syndrome is high functioning (odds ratio [OR] 5.0, confidence interval [CI]: 1.4-17.8), that a prior sex offender is currently married (OR 16.5, CI:3.5-99.8), that a litigious patient sued a surgeon for a retained sponge (OR 6.3, CI:1.7-24.3), and that a nonverbal patient had expressed prior interest in penile prosthesis surgery (OR 4.5, CI: 1.3-16.2). CONCLUSION: Ethical principles, including respect for autonomy, nonmaleficence, beneficence, and justice, are appropriately applied by urological prosthetic surgeons when ethical challenges arise. While the likelihood of offering penile prosthesis surgery is decreased with most ethical dilemmas, specific clinical factors often augment decision-making.

Excision and Circumferential Buccal Graft for Severe Meatus and Fossa Navicularis Strictures.

OBJECTIVE: To demonstrate our technique for glans sparing transurethral excision and circumferential buccal graft for severe strictures of the meatus and fossa navicularis. MATERIALS AND METHODS: Key steps of the procedure are use of a fixed retractor and stay sutures to retract the glans skin laterally, preplacing urethral sutures to improve visualization, and dividing the buccal graft in half so that dorsal and ventral portions of the anastomosis can be performed separately. RESULTS: As demonstrated in the video, this approach allows for the effective treatment of challenging meatus and fossa navicularis strictures while avoiding postoperative glans dehiscence and minimizing disruption of glans vasculature and sensation. CONCLUSION: Glans sparing transurethral excision and circumferential buccal graft is an effective technique for severe strictures of the meatus and fossa navicularis.

Innovating Incrementally: Development of the Modern Inflatable Penile Prosthesis.

PURPOSE OF REVIEW: The inflatable penile prosthesis (IPP) was introduced in 1973. Since that time, the fundamental design of the IPP has not changed, but numerous improvements to the device, surgery, and peri-operative management have resulted in a modern IPP with excellent reliability, infection control, safety profile, and user experience. RECENT FINDINGS: We describe important modifications to the IPP and review available data assessing the impact of these changes. We also discuss possible changes to the IPP that would result in continued improvement. Since its introduction in 1973, changes to the penile prosthesis have resulted in significant improvements in reliability, infection control, safety, and user experience. Design changes are anticipated to continue, resulting in a better and more versatile penile prosthesis.

Preoperative Ultrasound-Guided Wire Localization of the Lateral Femoral Cutaneous Nerve.

BACKGROUND: Difficulty and sometimes inability to find the lateral femoral cutaneous nerve (LFCN) intraoperatively is well known. Variabilities in the course of the nerve are well documented in the literature. In a previous paper, we defined a tight fascial canal that completely surrounds the LFCN in the proximal thigh. These 2 factors sometimes render finding the nerve intraoperatively, to treat meralgia paresthetica, very challenging. OBJECTIVE: To explore the use of preoperative ultrasound to minimize operative time and eliminate situations in which the nerve is not found. METHODS: Since 2011, we have used preoperative ultrasound-guided wire localization (USWL) in 19 cases to facilitate finding the nerve intraoperatively. Data were collected prospectively with recording of the timing from skin incision to identifying the LFCN; this will be referred to as the skin-to-nerve time. RESULTS: In 2 cases, the localization was incorrect. In the 17 cases in which the LFCN was correctly localized, the skin-to-nerve time ranged from 3 min to 19 min. The mean was 8.5 min, and the median was 8 min. CONCLUSION: Preoperative USWL is a useful technique that minimizes the time needed to find the LFCN. For the less experienced surgeon, it is extremely valuable. For the experienced surgeon, it can identify anatomical abnormalities such as duplicate nerves, which may not be readily recognizable without ultrasound. Collaboration between the surgeon and the radiologist is very important, especially in the early cases.

Immunohistochemical assessment of rat nerve isografts and immunosuppressed allografts.

OBJECTIVE: Autologous peripheral nerve grafts are commonly used clinically as a treatment for peripheral nerve injuries. However, in research using an autologous graft is not always feasible due to loss of function, which in many cases is assessed to determine the efficacy of the peripheral nerve graft. In addition, using allografts for research require the use of an immunosuppressant, which creates unwanted side effects and another variable within the experiment that can affect regeneration. The objective of this study was to analyze graft rejection in peripheral nerve grafts and the effects of cyclosporine A (CSA) on axonal regeneration. METHODS: Peripheral nerve grafts in inbred Lewis rats were compared with Sprague-Dawley (SD) rats to assess graft rejection, CSA side effects, immune responses, and regenerative capability. Macrophages and CD8+ cells were labeled to determine graft rejection, and neurofilaments were labeled to determine axonal regeneration. RESULTS: SD rats without CSA had significantly more macrophages and CD8+ cells compared to Lewis autografts, Lewis isografts, and SD allografts treated with CSA. Lewis autografts, Lewis isografts, and SD autografts had significantly more regenerated axons than SD rat allografts. Moreover, allografts in immunosuppressed SD rats had significantly less axons than Lewis rat autograft and isografts. DISCUSSION: Autografts have long been the gold standard for treating major nerve injuries and these data suggest that even though CSA is effective at reducing graft rejection, axon regeneration is still superior in autografts versus immunosuppressed allografts.

Basic techniques for long distance axon tracing in the spinal cord.

The regeneration of axons after a spinal cord injury or disease is attracting a significant amount of interest among researchers. Being able to assess these axons in terms of morphology, length and origin is essential to our understanding of the regeneration process. Recently, two specific axon tracers have gained much recognition; biotinylated dextran amine (BDA) 10 kDa as an anterograde tracer and cholera toxin-B as a retrograde tracer. However, there are still several complexities when using these tracers, including the volume that should be administered and the best administration site so that a significant amount of axons are labeled in the area of interest. In this article, we describe some simple procedures for injecting the tracers and detecting them. We also quantified the number of axons at different locations of the spinal cord. Our results show axons labeled from motor cortex injections traveled down to the lumbosacral spinal cord in 2 weeks, while BDA injections into the lateral vestibular nucleus and reticular formation took 3 weeks to label axons in the lumbosacral spinal cord. Moreover, this protocol outlines some basic procedures that could be used in any laboratory and gives insight into the number of axons labeled and how procedures could be tailored to meet specific researcher's needs.
