Introduction This study aimed to evaluate if race impacted outcomes or risk of disease progression in men on active surveillance (AS) for prostate cancer. We present the results from our majority African-American cohort of men in an equal access setting over a 5-year follow-up period. Patients and Methods All patients who elected AS for prostate cancer at the Southeast Louisiana Veterans Health Care System are entered into a prospectively managed observational database. Patients were divided into groups based on self-reported race. Grade group progression was defined as pathologic upgrading above International Society of Urological Pathology Grade Group 1 disease on subsequent biopsies following diagnostic biopsy. All tests were 2 sided using a significance of .05. Results A total of 228 men met inclusion criteria in the study, including 154 non-Hispanic African American and 74 non-Hispanic Caucasian American men, with a median follow-up of 5 years from the initiation of AS. Race was not predictive of Gleason grade progression, AS discontinuation, or biochemical recurrence on Cox multivariate analysis (HR = 1.01, 0.94, 0.85, P = .96, .79, .81, respectively). On Kaplan-Meier analysis at 5 years, African-American progression-free, AS discontinuation free, and overall survival probability was comparable to their Caucasian American counterparts (P > .05 for all). Conclusions Active surveillance is a safe treatment option for low and very low risk prostate cancer, regardless of race. African-American and Caucasian-American men did not have any significant difference in Gleason grade group progression in our cohort with 5-year follow-up.

Men with normal penis size sometimes mistakenly believe they have below average penile dimensions and often seek out treatment. Many men suffer from significant anxiety regarding this perceived defect. In this review, we evaluate the current literature of psychological, medical, and surgical treatment options for men with a complaint of a small penis.To review the current practice for treatment of men presenting for penile augmentation surgery.A literature review was conducted, using PubMed to identify current studies regarding penile enhancement. Search terms included "penile enhancement," "small penis anxiety," "small penis syndrome," "body dysmorphic disorder," and "penile augmentation."The literature consistently reveals that men who seek out penile augmentation surgery usually have normal penile dimensions. There are limited published data on the practice of penile lengthening surgery or procedures to increase penile girth. New techniques have expanded on suspensory ligament release, such as tissue grafting and flaps. Structured psychological counseling continues to be the recommended initial standard of care for these men.Many social forces have increased the perception among men that their penis size is inadequate. This increases anxiety and can lead to psychological disorders such as Penile Dysmorphic Disorder and Small Penis Syndrome. Men who undergo penile enhancement are often not satisfied with the results and may develop complications. Soubra A, Natale C, Brimley S, et al.

Challenges to the accurate and precise measurement of testosterone include deficiencies in standardization, variable reference ranges, expenses related to gold standard equipment, and other challenges. Total testosterone remains the most accessible for standard laboratories, while free testosterone and bioavailable testosterone may be useful adjuncts, particularly in men with low borderline testosterone values. Mass spectrometry is the gold standard measurement modality for total testosterone, while equilibrium dialysis followed by direct assessment with a trusted method is the gold standard technique for measuring free testosterone. Although reference ranges may vary, efforts to adapt reference ranges to different populations include age-adjusted values.

Introduction Botulinum neurotoxin (BoNT) is a recognized therapeutic agent of modern medical care, routinely used to treat medical conditions affecting a variety of organ systems including the musculoskeletal, integumentary, and urological domains. Ongoing research is exploring BoNT's potential role as a therapeutic agent for a variety of male sexual pathologies. Objective To review and analyze the literature regarding BoNT as a treatment option for male sexual dysfunction. Methods A PubMed search was performed for English-language articles in peer-reviewed journals between 1970 and 2019 (with one article from 1897). Relevant articles referenced within these texts were also included. One article did not have an accompanied English full-text available. The following search terms were used: “Botox”, “Botulinum toxin”, “Botulinum toxin A”, “Onabotulinum A”, “Abobutlinum A”, “BoNT”, “BoNT-A”, “Male sexual health”, “Male sexual pathology”, “Peyronie's disease”, “Premature ejaculation”, “Scrotal Pain”, “Penile Retraction”, “Scrotox”, “Erectile Dysfunction”, and “Botox in Urology”. Results There is interest in the potential role of BoNT in the treatment of male sexual pathologies. We identified studies that used BoNT to treat chronic scrotal content pain, premature ejaculation, erectile dysfunction, Peyronie's disease, penile retraction, and more. However, despite preclinical/clinical data indicating some potential efficacy and safety in these settings, a lack of robust clinical trial data has resulted in no current Food and Drug Administration–approved indications for the use of BoNT in the treatment of male sexual pathology. As a result, much of the current use of BoNT by today's providers is “off-label,” and ongoing clinical trials aim to further elucidate the potential role of this therapeutic agent. Conclusion Current data suggest that BoNT could have a potential role as a treatment option for certain types of male sexual pathologies. However, more randomized controlled trial data regarding its long-term safety and efficacy are necessary before a widespread clinical adoption can take place. Reddy AG, Dick BP, Natale C, et al.

Introduction Collagenase Clostridium histolyticum (CCH) is an injectable agent used to treat Peyronie's disease (PD) by enzymatically degrading the interstitial collagen in plaques. CCH has been administered via multiple treatment protocols, in combination therapies, to patients with varying curvatures and in both the acute and stable phases of this condition. Objectives To review the current literature and provide an update on CCH as an injectable therapy for PD, as a singular therapy or in conjunction with combination therapies, and its associated complications. We provide a brief background of PD treatments, evaluate CCH efficacy in penile curvature reduction and subjective improvement in a variety of protocols, and compare combination therapies (penile traction, sildenafil), plaque location, and efficacy in both acute and stable diseases. Methods We performed a systematic review of the existing PubMed literature pertaining to CCH injection therapy in the treatment of PD and compared the effectiveness to different treatment modalities. Results CCH is a safe and effective injectable agent for all curvature directions in both acute and stable PD. It can be used in conjunction with multiple penile modeling techniques, in combination with sildenafil, and following a shortened administration protocol. Moderate to severe treatment-related adverse events occur at a rate of 9% and are typically managed conservatively. Conclusion Intralesional injections of CCH are FDA approved as a nonsurgical treatment for men with PD. The IMPRESS trials were instrumental in demonstrating the efficacy and safety of CCH and provided a standard protocol for administration. Additional studies are required to optimize treatment protocols and use in combination therapies. Further investigation of patients with ventral curvatures, hourglass deformities, and those in acute phase is needed. Natale C, McLellan D, Yousif A, et al.

Introduction The past 2 decades have witnessed an increased amount of research into botulinum neurotoxin (BoNT) as a treatment for various forms of sexual dysfunction and pain syndromes refractory to other medical therapy. BoNT is postulated to reduce pain sensation by inhibiting neuropeptide release in the presynaptic neuron. Dyspareunia, vaginismus, vestibulodynia, and persistent genital arousal disorder are female sexual dysfunctions with cryptic pathophysiology and limited treatment options. BoNT has emerged as a potential treatment for many of these afflictions in women. Objectives To review the literature regarding BoNT as a treatment for female sexual and genitourinary dysfunction. Methods A PubMed search for English-language articles was performed using the following terms: “Botox,” “botulinum toxin,” “botulinum toxin A,” “Onabotulinum A,” “Abobutlinum A,” “BoNT,” and “BoNT-A.” The main outcomes measured by each study were resolution of dysfunction. This entailed reduction of pain with intercourse for dyspareunia, reduction of pain for vestibulodynia, decreased arousal for persistent genital arousal disorder, and ability to tolerate penetration for vaginismus. Results A total of 12 human studies that evaluated BoNT as a treatment for female sexual disorders were included. Study types included prospective, retrospective, cohort, pilot, and open-label. Conclusion There is growing evidence suggesting that BoNT is a safe and efficacious treatment option for female patients suffering from various sexual and genitourinary disorders. However, more research is needed to develop a better understanding of the mechanisms through which BoNT treats these disorders. Dick B, Natale C, Reddy A, et al.

Erectile dysfunction (ED) is both a common and complex disease process. Existing ED treatments do not always achieve adequate results. There is clinical interest in employing regenerative therapies, including low-intensity extracorporeal shockwave therapy (Li-ESWT), platelet rich plasma (PRP), and stem cell therapy (SCT), in the treatment of ED as adjunct or alternative treatments. Here, we present evidence for emerging shockwave- and cell-based regenerative therapies for the treatment of ED following a thorough review of the existing PubMed literature pertaining to Li-ESWT, PRP, and SCT in relation to the treatment of ED. Li-ESWT causes microtrauma in tissue that hypothetically upregulates angiogenesis and recruits stem cells. Several large-scale systematic reviews and meta-analyses have reported that Li-ESWT improved ED in humans. Additionally, evidence has commenced to show that Li-ESWT may be effective against two recognized and complex etiologies of ED: diabetic and neurogenic. PRP delivers an autologous sample rich in growth factors to damaged tissue. Animal model studies have demonstrated improved erectile function recovery as well as preservation of cavernous nerve axons. Studies with PRP in humans are limited. SCT utilizes the regenerative potential of stem cells for healing of damaged tissue. In the treatment of ED, SCT has been used in the setting of diabetic and post-prostatectomy ED. Results of human studies are varied, although SCT treatments did result in increased erectile rigidity with some patients recovering the ability to achieve penetration. While these regenerative therapies show potential to augment the current treatment regimen for ED, there is a paucity of evidence to support the safety and efficacy of these treatments. Further research is necessary to define the role of these alternative therapies in the treatment of ED.

To review the current literature on acute management of traumatic penile fracture, with a specific discussion of those injuries following collagenase clostridium histolyticum (CCH) injections for the treatment of Peyronie’s disease. The immediate repair of traumatic penile fracture injury is associated with significantly better prognosis for long-term sexual health. Corporal disruption following CCH administration has several distinct features, and the trend is to manage these patients conservatively in the absence of urethral injury. Traumatic penile fracture repair continues to have excellent results when performed immediately following injury. The post-CCH treatment setting portends increased difficulty during surgical management and can be successfully managed in most cases by conservative measures.

To analyze the literature on current conservative treatment options for Peyronie’s disease (PD). Conservative therapy with intralesional collagenase clostridium histolyticum (CCH) is safe and efficacious in either the acute or chronic phases of PD. Combination treatment with penile traction therapy (PTT) can produce even better results. While most PTT devices require extended periods of therapy up to 8 h per day, the RestoreX® device can be effective at 30–90 min per day. A variety of conservative therapies are available for treatment of PD. The available literature does not reveal any treatment benefit of oral therapies. Intralesional therapy is the mainstay conservative treatment of PD. Intralesional CCH therapy is the first Food and Drug Administration-approved intralesional therapy and represents the authors’ preference for medical therapy. The most effective conservative management of PD likely requires a combination of therapies.

Introduction Although telemedicine (TM) has been available for several decades, the recent increase in its acceptance due to the COVID-19 pandemic has emerged as a valuable solution for the delivery of health care that provides easy, affordable, and convenient communication with urologic patients. Objectives The objective of this study was to highlight limiting factors and provide successful practical solutions to assist urologists in incorporating and maintaining TM in their practices. Methods A thorough literature review was conducted utilizing PubMed, Cochrane library, clinicaltrials.gov , Google Scholar, and Web of Science. Search terms and keywords included “telemedicine” and “urology.” Only articles written or translated into the English language were included. Results A total of 12 peer-reviewed articles were identified that discussed barriers for incorporation of TM in urology. Articles exclusive to the use of TM during the COVID-19 pandemic were also included, as well as American Urological Association and European Urological Association guidelines and Centers for Medicare & Medicaid Services statements and policies regarding TM pertinent to urological practice. Conclusion TM is currently a viable option and fills an unmet need for most practicing urologists, especially during the COVID-19 pandemic, offering insight to the relative ease of transition to online clinical practice.

Introduction Although testosterone therapy (TTh) is the standard practice in otherwise healthy hypogonadal men, this therapy has historically been contraindicated in men with a history of prostate cancer. Recent evidence suggests that there is minimal or no prostate cancer growth in the setting of TTh administration in men definitively treated for non-metastatic prostate cancer. Objective To review the evidence supporting the safety and efficacy of TTh in patients previously treated for localized prostate cancer. Methods A literature review of the PubMed database was performed to identify studies evaluating the safety and efficacy of TTh in patients with a history of prostate cancer. Search terms included Testosterone Therapy, Testosterone Replacement Therapy and Radical Prostatectomy, Radiotherapy, External Beam Radiation Therapy, EBRT, Brachytherapy; Prostate Cancer and Hypogonadism, Low Testosterone; Bipolar Androgen Therapy. Results Available literature provides evidence for the safe application of TTh in patients previously treated for prostate cancer with either radical prostatectomy or radiotherapy. Furthermore, there exists evidence that severely hypogonadal levels of testosterone may lead to worse oncological outcomes. More recent research has begun to elucidate the effectiveness of bipolar androgen deprivation therapy in the treatment of prostate cancer. This mechanism of action increases the level of evidence indicating that the traditional management of maintaining testosterone levels at low levels may no longer be standard of care. TTh likely has a role in improved erectile function and other quality-of-life concerns in patients developing testosterone deficiency after being treated for prostate cancer. Conclusions TTh should be offered to select hypogonadal patients who have a history of definitively treated prostate cancer. Adequately designed randomized controlled trials are necessary to confirm the safety and efficacy of TTh in this population. Natale C, Carlos C, Hong J, et al.

Background Postorgasmic illness syndrome (POIS) is a rare syndrome of unknown etiology where patients experience distressing physical and psychological after ejaculatory sequelae. Aim To better characterize the epidemiology, symptomatology, disease course, and treatment of POIS, with specific interest placed on examining relationships between disease presentation and measures of disease burden. Methods A 30-item questionnaire was distributed to an online community of patients with POIS from June 2019 to January 2020. We assessed diagnostic criteria and clusters of symptomatology described in prior studies. Outcome measures include self-reported measures of symptom severity, disease burden, and behavioral changes. Statistical correlations were assessed with Pearson's chi-squared (χ2) and ordinal regression analyses. Outcomes The main outcome measures of this study are self-reported measures of symptom severity, disease burden, and behavioral changes. Results The sample consisted of 302 men (mean age: 32.6 ± 11.4 years, mean age of onset: 19.1 ± 7.8 years) with 89% satisfying ≥3 diagnostic criteria. Common symptoms were difficulty concentrating (254, 84%), extreme fatigue (250, 83%), irritability (225, 74%), and muscle weakness (212, 70%). Common symptom clusters were general (219, 72%), muscle (137, 45%), and head (93, 31%). Common behavioral modifications were avoiding masturbation (215, 71%), schedule changes (213, 71%), and abstinence (186, 62%). Head and throat symptom clusters demonstrated worse disease burden outcomes. Professional medical advice was sought by 51% of participants. Attempted treatments included pharmacotherapy, vitamins, supplements, and herbs with variable efficacy. Clinical Implications This study further characterizes POIS, including how patients respond to the condition, how it is treated in the community, and presentations that may be associated with more severe disease. Strengths & Limitations This is the largest study to date that concerns patients suffering from POIS and includes a diverse, global population. Limitations include that the survey was only administered in English and within 1 online community, that results were self-reported, and that the response rate was low (32%). Conclusions Characterizing symptom cluster, but not number of diagnostic criteria, may offer prognostic value, and investigation to elucidate pathophysiology and potential treatments for POIS is necessary.

Introduction There is an increased prevalence of erectile dysfunction in patients with solid organ transplant (SOT) compared with the general population. Many of these patients may become refractory to medical treatment of erectile dysfunction and penile prosthesis (PP) is often recommended. Concerns regarding the safety of PP in patients with SOT are due to their immunosuppressed state. Objective We aim to review all current literature on the outcomes of patients with SOT who have received PP. Methods A PubMed search was performed to identify articles pertaining to the outcomes of PP in patients with SOT. Results We identified and included 14 studies that report on outcomes of PP placement in 143 patients with SOT and 191 non-SOT controls from interval period from 1979 to 2019. Studies included retrospective cohort studies, case series, and case reports. Compared with non-SOT controls who had PP, aggregate analysis demonstrated that patients with SOT who had PP did not develop significantly increased overall complications. However, they were significantly more likely to experience future surgical complications. Conclusion Our aggregate analysis demonstrated that patients with SOT are not at a significantly increased risk of overall complications when receiving a PP. Nevertheless, there is an increased risk of experiencing PP injury during subsequent surgeries, which may be mitigated by the earlier involvement of a urologist. Given the lack of recent data, large studies are prerequisite to further evaluate the safety and overall outcome of PP surgery in patients with SOT. Dick B, Greenberg JW, Polchert M, et al.

Background: Although emerging evidence demonstrates increased risk of secondary bladder cancer following pelvic radiotherapy, the aggressiveness of these tumors is not well-characterized. Materials and Methods: A search of the Surveillance, Epidemiology, and End Results (SEER) 18 Database, identified 25,734 patients diagnosed with bladder cancer following definitive therapy for previous pelvic malignancy. Kaplan-Meier curve analyses were utilized to determine overall survival with significance set at p

Introduction Although available treatments for erectile dysfunction (ED) have expanded, there has been a concomitant shift in the treatment paradigm. Newer treatment options focus on disease modification and improving overall erectile function. Objective The objective of this study is to review the evidence of 3 promising novel ED treatments. Methods A thorough review of the literature was divided into sections corresponding to low-intensity extracorporeal shockwave therapy (Li-ESWT), stem cell therapy (SCT), and platelet-rich plasma (PRP). Search terms included “erectile dysfunction” or “ED” plus “extracorporeal shockwave therapy”, “stem cell therapy” or “platelet rich plasma”. International Index of Erectile Function (IIEF) scores were the primary outcome measure. Secondary outcome measures included peak systolic velocity and intracorporeal pressure. Results Li-ESWT section includes 1 randomized controlled study, 2 prospective studies, 1 animal study, and 2 meta-analyses. IIEF score improvement was 3.54 (range 1.99–6.40). Authors concluded statistically significant short-term effect and improvement in erectile function (EF) with Li-ESWT. SCT section included 4 case series and 1 open-label study. Intraperitoneal, venous, and cavernosal SCT injections improved EF in animal models. 3 studies (n = 6–8) demonstrated 83–100% and 29–50% of patients regained erection and penetration ability, respectively. 2 studies (n = 12–16) found that all patients improved IIEF scores after SCT. Literature review for PRP yielded 3 animal, 1 retrospective, and 1 prospective study. Animal studies have shown that rats sustaining crush cavernosal injuries treated with PRP significantly improved EF and preservation of cavernous nerve axons. One retrospective analysis on humans showed mean improvement by 4.14 in IIEF scores. One prospective study on humans (n = 75) demonstrated improved peak systolic velocity (P = .005) and IIEF scores (P = .046) with PRP therapy. Conclusions This review reveals limited published evidence on current novel ED treatment options. Further research on Li-ESWT, SCT, and PRP therapy is necessary to elucidate the role of these therapies in ED treatment regimens. Raheem OA, Natale C, Dick B, et al.

The objective of this study was to characterize the demographic, prognostic, and treatment factors for patients with primary adenocarcinoma of the bladder by analyzing the impact of histologic subtype in a large sample size and interpreting newly released Surveillance, Epidemiology, and End Results (SEER) chemotherapy data.The SEER 18 Registry was utilized to identify cases of primary adenocarcinoma diagnosed from 1973 to 2015. Demographic data, tumor and disease characteristics, treatment information, and survival outcome data were collected. Overall survival and disease-specific survival were determined using Kaplan-Meier curve analysis. Univariate and multivariate Cox regression analysis were then completed using SAS JMP.A total of 2305 cases of primary adenocarcinoma of the bladder were identified. Overall survival at 2-, 5- and 10-year intervals was 54.8%, 36.1%, and 25.4%, respectively. Disease-specific survival at 2-, 5- and 10-year intervals was 62.0%, 47.1%, and 40.1%, respectively. Patients were treated with surgery (86.4%), chemotherapy (21.9%), and radiation (15.0%) (P .0001). Multivariate Cox regression analysis showed independent prognostic value for gender, stage, grade, primary tumor location, and histologic subtype. The urachus/dome location conferred survival advantage over non-urachal locations on univariable and multivariable Cox regression analysis. The papillary adenocarcinoma subtype conferred the best survival outcome, whereas signet cell carcinoma (hazard ratio, 2.069; P .0001) and unclassified adenocarcinoma (not otherwise specified) (hazard ratio, 1.524; P .0001) conferred the worst prognoses.This study utilized a population-based analysis to showcase the utility of various prognostic features in primary bladder adenocarcinoma cases. In characterizing treatments, we find the prevailing treatment remains surgical intervention, whereas a sizable minority receives chemotherapy and/or radiation, often in combination with surgery.

210 Background: The UroNav fusion biopsy system allows for the real time visualization of the prostate using multi-parametric MRI (mpMRI) data. This technology has become a valuable instrument for staging prostate cancer at the time of PSA elevation. However, data is still yet emerging over the use of this tool for patients currently being followed on an active surveillance (AS) protocol. In this study we sought to evaluate the efficacy of the UroNav system in patients on AS. Methods: Patients were enrolled into our prospective study, at a single center institution, approved by the Southeast Louisiana Veterans Health Care System (SLVHCS) IRB. Inclusion criteria for this study was men previously enrolled in an active surveillance protocol with a life expectancy ≥10 years. Statical analysis was performed using R 4.0.2 (Ann Arbor, MI). Results: A total of 103 patients were entered into this study for analysis. These patients had a median age of 67.1(62.8 - 70.8) and BMI of 28.6(25.5 - 32.3). The clinical profiles of these patients were median PSA of 6.36(4.65 - 8.89) with a velocity slope of (0.065 (-0.14 - 0.27), TRUS volume of 39.5(32.2 - 56.8), PSAD of 0.15(0.09 - 0.23), and a PI-RAD score of 4(3 – 5). A logistic regression was performed using upgrading on UroNav or Template bx as the outcome. Patients with an increased PSA were more likely to upgrade of Bx (OR = 1.2 (1.05 - 1.39)). Additionally, patients with decreasing MRI volumes were also more likely to upgrade on Bx (OR = 0.97 (0.94 - 0.98)). A total of 42 (40%) patients upgraded on either MRI or Template bx from their initial AS workup. MRI found 13 (12.6%) patients with an upgraded GG that displayed consistent or benign disease on template. Conversely, template also found 13 (12.6%) unique patients who upgraded but were found to have constant or benign disease on mpMRI. Conclusions: mpMRI guided biopsy is a useful tool that can further assist physicians in characterizing prostate cancer in patients being concurrently followed on an active surveillance protocol. MRI is able to find clinically significant cancer that would have otherwise been missed on traditional template biopsies. [Table: see text]
