RESUMO
PURPOSE: The American Urological Association (AUA) Annual Meeting serves as the premier platform for presenting unpublished research in urology. Among selected abstracts, podium presentations represent the most impactful submissions. While podium presentations receive a large audience through conference attendance and social media posts, it is unclear how often they manifest as publications in peer-reviewed journals. MATERIALS AND METHODS: Podium presentations from the 2017 AUA Annual Meeting were reviewed. Abstracts were assessed for publication between January 1, 2015 and May 31, 2020 allowing for a 3-year window of publication and accounting for publications prior to the submission deadline. Abstract authors were individually searched with key terms being added sequentially until <30 results were generated in PubMed®. Abstracts were deemed published if at least 1 author and 1 conclusion matched a manuscript. Publication rate, time to publication, and 2019 journal impact factor were collected. Statistical analysis was performed by linear and logistic regression. RESULTS: Of 872 podium presentations, 453 (51.9%) were published within 3 years. Median time from submission to publication was 12.5 months (IQR: 7.5-20.5). The number of articles published at 1, 2 and 3 years from submission was 203, 368 and 430, respectively. The median journal impact factor of publications was 3.2 (IQR: 2.0-5.8). Oncology studies (OR=1.21 [95% CI: 0.91-1.60], p=0.186) had similar rates of publication compared to non-oncology studies. CONCLUSIONS: While AUA podium presentations disseminate valuable data, approximately half were not published in peer-reviewed journals within 3 years. Therefore, care must be taken when promoting findings or adopting new practices based on these presentations alone.

Background: Conventional operative insufflation uses a one-way trocar to handle instruments while maintaining pneumoperitoneum. In 2007, the AirSeal® valveless trocar insufflation system was introduced, which maintains stable pneumoperitoneum while continuously evacuating smoke. Although this device has been validated in adult patients, it has not been extensively validated in the pediatric population. Materials and Methods: A retrospective cohort study of pediatric urology patients aged 0 to 21 who underwent laparoscopic pyeloplasty between March 2016 and October 2021 was performed. Intraoperative physiologic parameters, procedure characteristics, postoperative outcomes, and demographics of each patient in whom either AirSeal insufflation system (AIS) or conventional insufflation system (CIS) was utilized were obtained from hospital records. Data were compared across the AIS and CIS cohorts. The primary outcomes were intraoperative anesthetic and physiologic parameters, including end tidal carbon dioxide, oxygen saturation, body temperature, positive inspiratory pressure, systolic blood pressure, and heart rate. Results: There were no significant differences in the anesthetic and physiologic parameters in the AIS and CIS groups. In addition, no differences in demographics, procedural characteristics, or complication rates were found between the cohorts. Conclusion: The AirSeal valveless trocar insufflation system demonstrates comparable intraoperative anesthetic and physiologic outcomes compared to conventional one-way valve insufflation in pediatric laparoscopic pyeloplasty. Certain surgeon-related qualitative metrics are underappreciated in this study, however, including improved visualization with vigorous suctioning and pressure maintenance with frequent instrument exchanges. Surgeon experience may mask the benefits of these characteristics as it pertains to quantitative surgical outcomes such as estimated blood loss, operative time, and perioperative complications.

Prostate papillary and cribriform ductal prostatic adenocarcinoma is a rare malignancy infrequently reported in the literature. We describe a case of rectally invasive prostate cystic adenocarcinoma and surgical extirpative management not requiring fecal or urinary diversion.
RESUMO
Thymoma is a unique neoplasm of the anterior mediastinum that is frequently associated with indolent growth and a variety of paraneoplastic syndromes. One third of cases are detected during the evaluation of myasthenia gravis. Classification systems of thymoma have limited ability in accurately predicting prognosis and course of disease. Thus, staging is the only way to predict clinical behavior. Encapsulated tumors that are surgically resected carry the best prognosis. Adjuvant radiotherapy is recommended for incompletely excised and most invasive thymomas. Chemotherapy in anthracycline-based chemotherapy remains the most effective chemotherapy for neoadjuvant, adjuvant or palliative treatment.

Treatment of metastatic renal cell carcinoma (mRCC) has evolved with the development of a variety of systemic agents; however, these therapies alone rarely lead to a complete response. Complete consolidative surgery with surgical metastasectomy has been associated with improved survival outcomes in well-selected patients in previous reports. No randomized control trial exists to determine the effectiveness of metastasectomy. Therefore, reviewing observational studies is important to best determine which patients are most appropriate for metastasectomy for mRCC and if such treatment continues to be effective with the development of new systemic therapies such as immunotherapy. In this narrative review, we discuss the indications for metastasectomies, outcomes, factors associated with improved survival, and special considerations such as location of metastasis, number of metastases, synchronous metastases, and use of systemic therapy. Additionally, alternative treatment options and trials involving metastasectomy will be reviewed.
RESUMO
OBJECTIVE: To evaluate the applicant experience with preference signaling during the 2022 Urology Residency Match. METHODS: An anonymous electronic survey was emailed to all urology residency applicants who applied to Rutgers Robert Wood Johnson Medical School during the 2021-2022 application cycle. The survey collected information regarding applicant demographics, applicant characteristics, preference signal destinations, match outcomes, and attitude towards preference signaling. RESULTS: A total of 601 applicants applied to the 2022 Urology Residency Match, 283 of which applied to the urology residency program at Rutgers Robert Wood Johnson Medical School. Of the 283 applicants, 53 (19%) responded to our survey. Rate of interview for preference signaled programs was 54.23%, with a significantly lower rate of interview for comparative, non-signaled programs (40.54%; P = .001). Of respondents, 14.29%, 26.19%, and 35.71% matched to their home program, a program they signaled, or a program where they completed an away rotation, respectively. 96% of applicants favored continuation of the preference signaling program. CONCLUSION: Our study suggests preference signaling in the 2022 Urology Match may have been an effective method of expressing interest in a program. Respondents of our survey overwhelmingly favor continuation of the program in future urology matches. However, it may not address the underlying, growing problem of the increasing application burden on applicants and programs alike. We encourage more comprehensive studies to further clarify the effects of preference signaling on the Urology Match.

While the gold-standard for management of localized renal cell carcinoma (RCC) is partial nephrectomy, recent ablative strategies are emerging as alternatives with comparable rates of complications and oncologic outcomes. Thermal ablation, in the form of radiofrequency ablation and cryoablation, is being increasingly accepted by professional societies, and is particularly recommended in patients with a significant comorbidity burden, renal impairment, old age, or in those unwilling to undergo surgery. Maturation of long-term oncologic outcomes has further allowed increased confidence in these management strategies. New and exciting ablation technologies such as microwave ablation, stereotactic body radiotherapy, and irreversible electroporation are emerging. In this article, we review the existing management options for localized RCC, with specific focus on the oncologic outcomes associated with the various ablation modalities.
RESUMO
Female urethral strictures are rare, but underdiagnosed pathologies that can cause voiding dysfunction. These strictures are best managed with open reconstruction, as endoscopic treatments have high rates of failure. A flap urethroplasty can be performed with vaginal, labial or bladder tissue. Meanwhile, graft urethroplasties can utilize vaginal, labial, buccal or lingual tissue. It is important to consider the etiology and type of stricture, local vascularity, and prior attempts at repair when selecting the type of repair. Multiple different techniques have been described with theoretical advantages to each one. While some studies have reviewed a few of the reconstructive techniques to treat female urethral strictures, no single study has accounted for each individual technique. In this review, we discuss techniques captured by a number of systematic reviews and other articles. We will herein focus on reviewing and describing each unique technique of reconstruction in the setting of female urethral stricture.
RESUMO
OBJECTIVES: To determine the incidence of further procedures and serious adverse events (SAEs) requiring admission to hospital following elective surgery for base of thumb osteoarthritis (BTOA), and the patient factors associated with these outcomes. DESIGN: Population based cohort study. SETTING: National Health Service using the national Hospital Episode Statistics data set linked to mortality records over a 19-year period (01 April 1998-31 March 2017). PARTICIPANTS: 43 076 primary surgeries were followed longitudinally in secondary care until death or migration on 37 329 patients over 18 years of age. MAIN OUTCOME MEASURES: Incidence of further thumb base procedures (including revision surgery or intra-articular steroid injection) at any time postoperatively, and local wound complications and systemic events (myocardial infarction, stroke, respiratory tract infection, venous thromboembolic events, urinary tract infection or renal failure) within 30 and 90 days. To identify patient factors associated with outcome, Fine and Gray model regression analysis was used to adjust for the competing risk of mortality in addition to age, overall comorbidity and socioeconomic status. RESULTS: Over the 19 years, there was an increasing trend in surgeries undertaken. The rate of further thumb base procedures after any surgery was 1.39%; the lowest rates after simple trapeziectomy (1.12%), the highest rates after arthroplasty (3.84%) and arthrodesis (3.5%). When matched for age, comorbidity and socioeconomic status, those undergoing arthroplasty and arthrodesis were 2.5 times more likely to undergo a further procedure (subHR 2.51 (95% CI 1.81 to 3.48) and 2.55 (1.91 to 3.40)) than those undergoing simple trapeziectomy. Overall complication rates following surgery were 0.22% for serious local complications and 0.58% for systemic events within 90 days of surgery. CONCLUSIONS: The number of patients proceeding to BTOA surgery has increased over the last 19 years, with a low rate of further thumb base procedures and SAEs after surgery overall registered. Arthrodesis and arthroplasty had a significantly higher revision rate. TRIAL REGISTRATION NUMBER: NCT03573765.

BACKGROUND: Hand fractures are common and sometimes require surgery to restore function. Placement of Kirschner wires (K-wires) is the most common form of surgical fixation. After placement, a key decision is whether to bury the end of a K-wire or leave it protruding from the skin (exposed). A recent systematic review found no evidence to support either approach and a national clinician and surgeon survey demonstrated further uncertainty. We aim to determine the design of a definitive randomised controlled trial assessing the cost and clinical effectiveness of buried versus exposed Kirschner wires for adults with metacarpal or phalangeal fractures. METHODS: We will employ three methodologies: a national service evaluation of current clinical practice, patient and surgeon focus groups and a consensus meeting to finalise the protocol for a randomised controlled trial. For the service evaluation, all outcomes will be summarised using descriptive statistics overall and split by group (buried versus exposed K-wires). Information collected in the patient focus groups will be analysed thematically. The surgeon consensus meeting will address each part of the design in turn and through discussion agree a final protocol. DISCUSSION: The study may be monitored, or audited in accordance with the current approved protocol, Good Clinical Practice (GCP), relevant regulations and standard operating procedures. The Chief Investigator will submit and, where necessary, obtain approval from the above parties for all substantial amendments to the original approved documents. A feasibility study report will be published by the Wire Study Steering committee. Additional members of the steering group and citable collaborators will be listed within the manuscript and their roles identified.
RESUMO
OBJECTIVE: Nutraceutical products are widely used for their claimed therapeutic benefits. However, falsified or adulterated nutraceuticals present a major health threat to consumers. This study investigates the pharmaceutical quality, safety and anti-inflammatory effects of six male enhancement nutraceuticals that claim to be 100% natural. METHODS: Three batches of six male enhancement products were tested to detect the presence and levels of adulterants via high-performance liquid chromatography (HPLC). The pharmaceutical quality of the selected nutraceuticals was tested with near infrared spectroscopy (NIR) and SeDeM. The cytotoxic effects of these products on HepG2 cells were determined through cell proliferation (XTT) and lactate dehydrogenase (LDH) cytotoxicity assays. Lastly, the in vitro inflammatory effects of these products were investigated using murine J774 macrophages through cytokine release analysis. RESULTS: HPLC analysis detected the presence of sildenafil citrate, a vasodilator, and the active ingredient in Viagra and Revatio, in all batches of the products we analyzed. Amount of sildenafil citrate ranged from 0.45 mg to 51.85 mg among different batches. NIR assessment showed inter- and intra-batch heterogeneity in product composition. Results of the XTT and LDH assays showed significant cytotoxic effects of the analyzed products. XTT analysis revealed that the viability of HepG2 treated with tested products varied from 27.57% to 41.43%. Interestingly, the male enhancement products also showed anti-inflammatory effects. CONCLUSION: Despite their labeling as 100% natural, all products tested in this study contained levels of sildenafil citrate, which was not reported on the packaging. There was a lack of pharmaceutical uniformity among products of the same batch and across different batches. Additionally, the products we tested had cytotoxic effects. These study findings highlight the adulteration, poor quality and hazard of these nutraceuticals. Therefore, strict regulation of these products and standardization of the definition of nutraceuticals are urgently needed. Further, these falsely advertised products should be withdrawn from the market due to potential adverse effects on the health of their consumers.

Background: The aim of this study was to evaluate the effectiveness of interventions for acute complete rupture of the ulnar collateral ligament (UCL) of the thumb in adults. Methods: The following databases were searched: MEDLINE and EMBASE via OVID, CINAHL and SPORTDiscus via EBSCO, from database inception to 31 st January 2018. Inclusion criteria were: (i) randomised controlled clinical trials (RCTs) or study of intervention with a comparator; (ii) participants with diagnosis of acute complete rupture of the UCL of the thumb; (iii) participants aged 18 years of age or older at enrolment; and (iv) published in a peer-reviewed English-language journal. Results: In total, six studies were identified for inclusion after screening. All studies had a high risk of bias. Three studies were retrospective comparative case series which compared two different surgical techniques (bone anchor versus pull out suture, suture versus pull out suture, suture versus steel wire). Of these studies, three were RCTs, two of which compared different rehabilitation regimes in patients managed surgically (plaster versus early mobilization, new spica versus standard spica). The remaining RCT compared two different rehabilitation regimes in a mixed group of surgically/non-surgically treated patients. The RCT comparing a standard spica with a new spica demonstrated a statistically significant improvement in outcomes with the new spica at all time points (range of motion, Dreiser index and VAS); this was also the only study to provide sufficient outcome data for further analysis. Conclusion: There is no prospective evidence comparing surgery to non-operative treatment for acute complete ruptures of the ulnar collateral ligament of the thumb. There is weak evidence to suggest that early mobilisation may be beneficial following surgical repair. Further research is necessary to better define which patients benefit from which specific interventions.
