Multiple plaque incisions with or without grafting for Peyronie's disease.

Objectives: To assess novel surgical techniques in management of Peyronie's disease. Subjects: Forty-three men underwent corrective surgery using either partial plaque incision and nongraft (PPING) or multiple plaque incisions and graft (MPIG). The technique used was determined intra-operatively. Patients were assessed at baseline and follow-up based on Peyronie's disease questionnaire patient-reported outcome measure (PDQ-PROM) and erectile function. Results: The two groups were well matched in age and erectile function. At baseline MPIG group had greater deformity and poorer patient-reported outcome. Penile curvature improved from 67.9° to 10.5° in the PPING group and 77.9° to 7.1° with MPIG. PDQ-PROM improved from 29 to 13 in those who underwent PPING and 38.5 to 17.6 in those undergoing MPIG. Erectile function was preserved in both groups. Conclusions: These novel surgeries are effective in restoring penile shape and length while preserving erectile function. This is reflected in improved patient-reported outcomes. These findings should be verified by multi-institutional study.

The Virtue quadratic male sling for postradical prostatectomy urinary incontinence: 3-Year outcome measurements and a predictive model of surgical outcome from a European prospective observational study.

AIMS: This prospective multicenter observational study evaluated postprostatectomy incontinence treatment outcomes with Virtue male sling at 12 and 36 months. METHODS: Objective assessment was based on a 24-h pad weight test with improvement defined by a decrease >50% and cure by less than 1.3 g. Subjective assessment was based on the patient global impression of improvement and International Consultation on Incontinence Questionnaire-urinary incontinence-short form (ICIQ-UI-SF) questionnaires. Subgroups were analyzed by baseline severity of incontinence on a 24-h-pad test, body mass index (BMI), and pads usage. Factors associated with treatment response were assessed using logistic regression at Months 36. Complications were reported. RESULTS: We analyzed data from 117 men. Objective and subjective improvement were achieved in 54% and 35% and 51% and 34% at 12 and 36 months, respectively. Twenty-one percent and 19% were considered cured, respectively, at 12 and 36 months. No differences per baseline incontinence severity, BMI and pads usage were found at 36 months. Mean ICIQ-UI-SF score decreased from 15 to 9. Predictive factors were BMI, postvoid residual urine, number of nighttime urination, and ICIQ total score. Seven Clavien-Dindo Grade III (5.1%) including four Virtue sling revisions were reported. The most frequent Grade II complications were overactive bladder symptoms and pain reported in 10.3% and 2.9%, respectively. No complications required explantation. CONCLUSIONS: Virtue male sling is safe and effective in males with mild to severe postprostatectomy urinary incontinence over 36 months. Virtue could be considered an interesting option for postradical prostatectomy urinary incontinence with positive results over time even in patients with high BMI. The predictive model should be validated by further studies.

The association of Coronavirus Disease-19 mortality and prior bacille Calmette-Guerin vaccination: a robust ecological analysis using unsupervised machine learning.

Population-level data have suggested that bacille Calmette-Guerin (BCG) vaccination may lessen the severity of Coronavirus Disease-19 (COVID-19) prompting clinical trials in this area. Some reports have demonstrated conflicting results. We performed a robust, ecologic analysis comparing COVID-19 related mortality (CRM) between strictly selected countries based on BCG vaccination program status utilizing publicly available databases and machine learning methods to define the association between active BCG vaccination programs and CRM. Validation was performed using linear regression and country-specific modeling. CRM was lower for the majority of countries with a BCG vaccination policy for at least the preceding 15 years (BCG15). CRM increased significantly for each increase in the percent population over age 65. A higher total population of a country and BCG15 were significantly associated with improved CRM. There was a consistent association between countries with a BCG vaccination for the preceding 15 years, but not other vaccination programs, and CRM. BCG vaccination programs continued to be associated with decreased CRM even for populations < 40 years old where CRM events are less frequent.

The role of the urologist, BCG vaccine administration, and SARS-CoV-2: An overview.

OBJECTIVES: To summarize the available literature regarding bacillus Calmette-Guerin (BCG) administration, severe acute respiratory syndrome conoravirus-2 (SARS-CoV-2), and the resulting clinical condition coronavirus disease (COVID-19) in light of recent epidemiologic work suggesting decreased infection severity in BCG immunized populations while highlighting the potential role of the urologist in clinical trials and ongoing research efforts. MATERIALS AND METHODS: We reviewed the available literature regarding COVID-19 and BCG vaccination. Specifically, the epidemiologic evidence for decreased COVID-19 morbidity in countries with BCG vaccination programs, current clinical trials for BCG vaccination to protect against COVID-19, potential mechanisms and rationale for this protection, and the role of the urologist and urology clinic in providing support and/or leading ongoing efforts. RESULTS: Epidemiologic evidence suggests that the crude case fatality rates are lower for countries with BCG vaccination compared to those without such programs. Four prospective, randomized clinical trials for BCG vaccination were identified including NCT04348370 (BADAS), NCT04327206 (BRACE), NCT04328441 (BCG-CORONA), and NCT04350931. BCG administration may contribute to innate and adaptive immune priming with several opportunities for translational research. CONCLUSIONS: The urologist's expertise with BCG and the infrastructure of urologic clinics may afford several opportunities for collaboration and leadership to evaluate and understand the potential role of BCG in the current COVID-19 pandemic.

COVID-19 and Bacillus Calmette-Guérin: What is the Link?

The debate around the role of vaccination with Bacillus Calmette-Guérin has revived right in the time of the Coronavirus disease 19 pandemic. Since Bacillus Calmette-Guérin is one of the most commonly delivered therapies in urology, in this editorial we discuss some points that we think will be of interest and guidance to practicing urologists during this public health emergency.

Advances in Penile-Preserving Surgical Approaches in the Management of Penile Tumors.

Penile-preserving surgery offers a revolutionary alternative to more traditional radical surgery. It offers better sexual, functional, and psychological results and evidence suggests it achieves this without sacrificing oncological outcomes. We examined the evolving nature of such surgeries, addressing controversies such as safe margins and survival outcomes and discussing more conventional techniques, including laser. At our UK center, we treat a high volume of penile cancer and here, based on such experience, we describe our glans resurfacing, glansectomy, and partial penectomy techniques; their application by disease stage; and the limitations of such surgeries.

Penile cancer: organ-sparing techniques.

To compare the oncological safety of treating patients with penile cancer with conservative techniques developed to preserve function, cosmesis and psychological well-being with more radical ablative strategies. We conducted an extensive review of the literature of penile-preserving and ablative techniques and report on the oncological as well as functional outcomes. There were no randomised studies comparing penile-preserving and ablative techniques. Most studies consisted of retrospective cohorts. The quality of evidence was level 3 at best. Cancer-specific survival is similar in penile-preserving and ablative approaches for low-stage disease. Penile preservation is better for functional and cosmetic outcomes and should be offered as a primary treatment method in men with low-stage penile cancer.

Primary prevention and vaccination for penile cancer.

The outcome of penile cancer is proportional to the stage at presentation. Strategies aimed at primary prevention would have a clear advantage, both for the individual and in terms of health economics. A number of preventative measures could be employed, including circumcision, smoking cessation, education on hygiene and human papillomavirus (HPV) prevention. There is a high prevalence of HPV infection associated with penile cancer worldwide. The recent development of HPV vaccines has facilitated interest in their use for the prevention of penile cancer. In this article we review the literature surrounding penile cancer prevention and HPV vaccination in men.

Fibroblast growth factor receptor 3 is a rational therapeutic target in bladder cancer.

Activating mutations of fibroblast growth factor receptor-3 (FGFR3) have been described in approximately 75% of low-grade papillary bladder tumors. In muscle-invasive disease, FGFR3 mutations are found in 20% of tumors, but overexpression of FGFR3 is observed in about half of cases. Therefore, FGFR3 is a particularly promising target for therapy in bladder cancer. Up to now, most drugs tested for inhibition of FGFR3 have been small molecule, multityrosine kinase inhibitors. More recently, a specific inhibitory monoclonal antibody targeting FGFR3 (R3Mab) has been described and tested preclinically. In this study, we have evaluated mutation and expression status of FGFR3 in 19 urothelial cancer cell lines and a cohort of 170 American patients with bladder cancer. We have shown inhibitory activity of R3Mab on tumor growth and corresponding cell signaling in three different orthotopic xenografts of bladder cancer. Our results provide the preclinical proof of principle necessary to translate FGFR3 inhibition with R3Mab into clinical trials in patients with bladder cancer.

ICUD-EAU International Consultation on Bladder Cancer 2012: Screening, diagnosis, and molecular markers.

CONTEXT AND OBJECTIVE: To present a summary of the 2nd International Consultation on Bladder Cancer recommendations on the screening, diagnosis, and markers of bladder cancer using an evidence-based strategy. EVIDENCE ACQUISITION: A detailed Medline analysis was performed for original articles addressing bladder cancer with regard to screening, diagnosis, markers, and pathology. Proceedings from the last 5 yr of major conferences were also searched. EVIDENCE SYNTHESIS: The major findings are presented in an evidence-based fashion. Large retrospective and prospective data were analyzed. CONCLUSIONS: Cystoscopy alone is the most cost-effective method to detect recurrence of bladder cancer. White-light cystoscopy is the gold standard for evaluation of the lower urinary tract; however, technology like fluorescence-aided cystoscopy and narrow-band imaging can aid in improving evaluations. Urine cytology is useful for the diagnosis of high-grade tumor recurrence. Molecular medicine holds the promise that clinical outcomes will be improved by directing therapy toward the mechanisms and targets associated with the growth of an individual patient's tumor. The challenge remains to optimize measurement of these targets, evaluate the impact of such targets for therapeutic drug development, and translate molecular markers into the improved clinical management of bladder cancer patients. Physicians and researchers eventually will have a robust set of molecular markers to guide prevention, diagnosis, and treatment decisions for bladder cancer.
