RESUMO

INTRODUCTION: Patients who seek urologic care have recently reported a high degree of financial toxicity from prescription medications, including management for nephrolithiasis, urinary incontinence, and urological oncology. Estimating out-of-pocket costs can be challenging for urologists in the US because of variable insurance coverage, local pharmacy distributions, and complicated prescription pricing schemes. This article discusses resources that urologists can adopt into their practice and share with patients to help lower out-of-pocket spending for prescription medications. METHODS: We identify 4 online tools that are designed to direct patients toward more affordable prescription medication options: the Medicare Part D Plan Finder, GoodRx, Amazon, and the Mark Cuban Cost Plus Drug Company. A brief historical overview and summary for patients and clinicians are provided for each online resource. A patient-centered framework is provided to help navigate these 4 available tools in clinic. RESULTS: Among the 4 tools we identify, there are multiples tradeoffs to consider as financial savings and features can vary. First, patients insured by Medicare should explore the Part D Plan Finder each year to compare drug plans. Second, patients who need to urgently refill a prescription at a local pharmacy should visit GoodRx. Third, patients who are prescribed recurrent generic prescriptions for chronic conditions can utilize the Mark Cuban Cost Plus Drug Company. Finally, patients who are prescribed 3 or more chronic medications can benefit from subscribing to Amazon RxPass. CONCLUSIONS: Prescription medications for urologic conditions can be expensive. This article includes 4 online resources that can help patients access medications at their most affordable costs. Urologists can provide this framework to their patients to help support lowering out-of-pocket drug costs.

RESUMO

This article discusses the ideal neurogenic bladder management team for patients who have neurogenic lower urinary tract dysfunction (NLUTD). It emphasizes the importance of a diverse team, including urologists, physiatrists, neurologist and others, working collaboratively to prevent complications and enhance patient outcomes. Owing to the unique nuances of the various neurologic conditions and patterns of NLUTD dysfunction, the roles of different specialists in the interdisciplinary team are outlined. This article describes 3 team models: multidisciplinary, interdisciplinary, and transdisciplinary, highlighting the benefits of collaborative approaches.

RESUMO

INTRODUCTION: We investigate and analyze the available information regarding on-call patterns among urologists in the US. METHODS: The AUA Workforce Workgroup collaborated with the AUA Data Team to analyze information from the 2022 AUA Census. Extracted data were analyzed to identify variability across gender, subspecialty, hours worked per week, AUA section, salary, and practice setting. We used χ2 tests to compare the groups with respect to each factor and defined statistical significance as a P value less than .05. RESULTS: There were significant differences by gender and several other on-call factors including being required to take call to maintain hospital privileges (reported by 76% of female urologists vs 67% of male urologists; P = .026), getting paid for weekend call (28% of females vs 38% of males; P = .030), and making over $500 per day when taking weekend call (18% of females vs 32% of males; P < .001). Other differences existed between AUA sections in percentage of physicians receiving over $500 for weekday or weekend calls (P < .001). Lastly, practice setting differed in likelihood of being paid over $500 for weekday call (44% reported by private practice urologists, 7% reported by academic urologists, 14% reported by institutional urologists; P < .001). CONCLUSIONS: These results underscore the substantial variability in on-call responsibilities and structure within the AUA workforce. Further research and regular participation in future censuses are recommended to continue to characterize these trends.

RESUMO

PURPOSE: Artifacts from poor ureteroscopes' light design with shadowing and dark areas in the field of view have been reported. The aim was to quantify effects of light obstruction in a kidney calyx model. METHODS: We evaluated a series of contemporary flexible ureteroscopes including the Storz Flex-Xc and Flex-X2s, Olympus V3 and P7, Pusen 7.5F and 9.2F, as well as OTU Wiscope using an enclosed 3D-printed pink in vitro kidney calyx model submerged in saline, where the field of light was intentionally partially obstructed alternatively at 12, 3, 6, and 9 o'clock. A color spectrometer was used for illuminance measurements at a 45° opening position in the background of the model. RESULTS: Overall and mean background illuminance for each obstructive situation were significantly different between scopes for both 50% and 100% brightness settings (ANOVA p < 0.001). At 50% brightness setting, almost all scopes had their highest and lowest background illuminance with the 6 o'clock and 3 o'clock obstructive situation, respectively. At 100% brightness setting, these became 6 o'clock and 12 o'clock obstructive situations. Considering each obstructive situation individually, the Flex-Xc was consistently the scope with highest background illuminance and the Pusen 7.5F the lowest. Background illuminance for each obstructive situation varied significantly for each scope individually, with the greatest range of variability for Pusen 7.5F and V3. CONCLUSIONS: Illuminance performance of ureteroscopes within an obstructed calyx model differ significantly for various obstructive situations. Urologists should be aware of this to help guide their choice of ureteroscope.

RESUMO

PURPOSE: The study aimed to assess the efficacy of OpenAI's advanced AI model, ChatGPT, in diagnosing urological conditions, focusing on kidney stones. MATERIALS AND METHODS: A set of 90 structured questions, compliant with EAU Guidelines 2023, was curated by seasoned urologists for this investigation. We evaluated ChatGPT's performance based on the accuracy and completeness of its responses to two types of questions [binary (true/false) and descriptive (multiple-choice)], stratified into difficulty levels: easy, moderate, and complex. Furthermore, we analyzed the model's learning and adaptability capacity by reassessing the initially incorrect responses after a 2 week interval. RESULTS: The model demonstrated commendable accuracy, correctly answering 80% of binary questions (n:45) and 93.3% of descriptive questions (n:45). The model's performance showed no significant variation across different question difficulty levels, with p-values of 0.548 for accuracy and 0.417 for completeness, respectively. Upon reassessment of initially 12 incorrect responses (9 binary to 3 descriptive) after two weeks, ChatGPT's accuracy showed substantial improvement. The mean accuracy score significantly increased from 1.58 ± 0.51 to 2.83 ± 0.93 (p = 0.004), underlining the model's ability to learn and adapt over time. CONCLUSION: These findings highlight the potential of ChatGPT in urological diagnostics, but also underscore areas requiring enhancement, especially in the completeness of responses to complex queries. The study endorses AI's incorporation into healthcare, while advocating for prudence and professional supervision in its application.

RESUMO

PURPOSE: To understand the treatment plans suggested for BCG-unresponsive non-muscle invasive disease (NMIBC) patients in the Arab countries and therapeutic decisions applied for BCG-naive patients during BCG shortage time. METHODS: A 10-minute online survey was distributed through the Arab Association of Urology (AAU) office to urologists in the Arab countries who treat patients with NMIBC. RESULTS: One hundred six urologists responded to the survey. The majority of urologists had treated, in the past 6 months, > 10 patients with NMIBC who were considered BCG-unresponsive (55% of respondents). Radical cystectomy (RC) was the most popular treatment option (recommended by 50%) for these patients. This was followed by intravesical chemotherapy (30%), repeat BCG therapy (12%), resection with ongoing surveillance (8%). Clinical trials and intravenous checkpoint inhibitors were never selected. The most preferred intravesical chemotherapy was by ranking: 60% gemcitabine, 19% mitomycin C, 8% docetaxel, 8% gemcitabine/docetaxel, 4% sequential gemcitabine/mitomycin C, and 1% valrubicin. The use of intravesical chemotherapy appears limited by Arab urologists due to concerns regarding clinical efficacy (fear of progression) and the lack of clear recommendations by urology societies. Given the BCG shortage, which may vary per Arab country, Arab urologists have adjusted by prioritizing BCG for T1 and carcinoma in situ (CIS) patients over Ta, adapting intravesical chemotherapy, and reducing the dose/strength of BCG administered. Most physicians report an eagerness to utilize novel therapies to address the BCG deficit, especially to try intravesical chemotherapy. CONCLUSIONS: Even though Arab urologists are in the majority of cases selecting RC for BCG-unresponsive cases, one-third of them are most recently initiating intravesical chemotherapy as an alternative option. To further assist Arab urologists in the appropriate selection of BCG unresponsive high risk NMIBC patient treatments, enhanced education and pathway protocols are needed.

RESUMO

OBJECTIVES: To provide a practical review of immune-related adverse events (irAEs) that may be encountered in uro-oncology patients. PATIENTS AND METHODS: We conducted a literature review of studies reporting irAEs including articles published through September 2023 for uro-oncology patients and the potential relevancy for the practicing urologist. RESULTS: Immunotherapy has revolutionised cancer treatment, extending its impact to urological malignancies including for patients with urothelial, kidney, and prostate cancers. Immuno-oncology (IO) compounds have achieved measurable and durable responses in these cancers. Urologists, choosing to administer or co-manage IO patient care, should be prepared to understand, evaluate, and treat irAEs. This review discusses the spectrum of irAEs that can be encountered. Ongoing trials are exploring the use of immunotherapy at earlier stages of uro-oncological diseases, thus underscoring the evolving landscape of urological cancer treatment. Paradoxically, some data suggests that the occurrence of irAEs is associated with improved oncological outcomes. CONCLUSIONS: Immune-related AEs, while manageable, may be life-threatening and require lifelong therapy. A thorough understanding of AEs and toxicity of a novel drug class is imperative.

RESUMO

Prostate cancer remains a prevalent concern worldwide, necessitating continual advancements in treatment modalities. This abstract explores the role of brachytherapy as a viable and effective option in the management of prostate cancer. Brachytherapy involves the implantation of radioactive sources directly into the prostate, providing a localized dose of radiation. n recent studies and clinical trials, brachytherapy has demonstrated promising outcomes, particularly in terms of disease control and patient outcomes. The treatment's ability to deliver a concentrated intraprostatic dose, often in combination with external beam radiotherapy, has shown favorable results. Furthermore, brachytherapy's impact on disease-free survival and its potential in reducing urinary and bowel toxicity have been subjects of investigation. This abstract delves into the technical aspects, patient outcomes, and emerging trends in brachytherapy for prostate cancer. By examining the current literature and research findings, we aim to shed light on the evolving role of brachytherapy in the comprehensive management of prostate cancer, emphasizing its potential as a valuable therapeutic option.

RESUMO

PURPOSE OF REVIEW: This review article will examine the current literature on hypospadias-related complications in adult patients. RECENT FINDINGS: In this article, we will review the most recent studies evaluating hypospadias-related stricture disease, erectile function, fertility, and psychosexual outcomes in adult men with history of hypospadias repair in childhood. Managing hypospadias-related complications in adult patients is challenging to reconstructive urologists due to the compounded complexity of innate tissue deficiency and history of prior surgical repairs. In this review, we explore overall functional outcomes of adults with history of hypospadias repair as well as repair strategies of hypospadias-related urethral stricture disease. We will review erectile function, fertility and psychosexual outcomes as well as potential complications, which often do not surface until late adolescence and adulthood. Although it is challenging to characterize and quantify hypospadias-related complications, further longitudinal study is needed to better care for this complex patient population.

RESUMO

PURPOSE OF REVIEW: Lasers have had a significant impact on the treatment of benign prostatic hypertrophy. This article attempts to distill the advancements in laser technology for the treatment of benign prostatic hypertrophy (BPH) into key and understandable points to help make this topic more accessible to urologists. RECENT FINDINGS: The holmium:yttrium-aluminum-garnet (YAG) laser, one of the most significant lasers in the field of urology, has recently been improved with pulse modulating technology (Moses™ technology). New thulium:YAG technology allows both pulsed and continuous wave modes. The thulium fiber laser is one of the newer lasers to come to market and has been shown to have effective and safe outcomes. GreenLight™ lasers are predominantly used in photovaporization procedures and have also been studied extensively, although less in recent years. The modern urologist is fortunate to have many high-quality lasers and a wide variety of surgical techniques to choose from when treating BPH. Understanding the basic laser principles and applications will help urologists to select the best treatment options for their patients with BPH.

RESUMO

INTRODUCTION: Grant funding to Urology has decreased over the last decade. Documented lack of gender and race diversity at the faculty level raises concerns for funding disparities. This study sought to characterize disparities based upon race and gender in National Institutes of Health (NIH) funding data to Urologic faculty. METHODS AND MATERIALS: Data from 145 ACGME accredited Urology residency programs incorporating faculty gender and underrepresented in medicine (URiM) status was utilized. The NIH Research Portfolio Online Report Tool was queried between 1985 and 2023 for grants related to current Urology faculty. URiM status, gender, years of practice, academic rank, and Doximity residency program rank were factors in multivariable analysis. RESULTS: A total of 2,131 faculty were included. Three hundred one Urologists received 793 urologic grants for a total of $993,919,052 in funding. By race, grants were awarded to: White 72.9%, Asian 21.8%, Hispanic 3.0%, Black 2.1%. Men received 708 grants (89.3%) worth $917,083,475 total. Women received 85 grants (10.7%) worth $76,835,577 total. Likelihood of being awarded a grant was significantly associated with non-URiM status (p < 0.001) and men (p < 0.0001). On multivariable analysis, Doximity rank (p < 0.001) and academic rank (p < 0.001) were significant predictors of receiving a grant; male gender, URiM status, and years of practice were not. Academic rank was also a significant predictor of number of grants received (p = 0.04) and total funding (p = 0.04); years of practice, Doximity rank, URiM status, and gender were not. CONCLUSIONS: NIH grants were more likely awarded to higher ranked faculty from higher Doximity ranked institutions with no differences based on URiM status or gender.

RESUMO

INTRODUCTION: With no recommended screening approach, urinary bladder cancer patients rely on referral to urologists to ensure timely diagnosis of bladder cancer. This requires coordination between primary and specialty care. We provide estimates of the relative association between primary care physician and urologist density on stage of urinary bladder cancer diagnosis. METHODS: We used 2010 to 2016 Pennsylvania Cancer Registry data to identify all adult patients diagnosed with bladder cancer. Our primary outcome was locoregional stage of diagnosis, since treatment modality changes and prognosis worsens beyond this stage. Based on patient's residential location at the time of diagnosis we defined both density of urologists and number of primary care providers (defined as providers per population) within the patient's county. We used univariate and multivariate logistic regression to estimate the association between provider density and likelihood of locoregional stage of diagnosis. We also controlled for age, sex, race/ethnicity, insurance type, and year. RESULTS: Our sample included 11,771 urinary bladder cancer patients with 10,607 diagnosed at locoregional stage and 1164 at distant stage. Multivariate regression results show primary care density was associated with significantly higher odds of locoregional stage of diagnosis (odds ratio of 1.05 [95% CI: 1.02-1.08]) while urologist density was associated with significantly lower odds of locoregional stage (odds ratio of 0.65 [95% CI: 0.48-0.89]). CONCLUSIONS: We found primary care density but not urologist density was associated with earlier stage of diagnosis, highlighting the importance of access to primary care and need for timely referral to urologic care.

RESUMO

OBJECTIVES: To characterise the prevalence of impostor phenomenon (IP; tendency for high-achieving individuals to perceive themselves as fraudulent in their successes) amongst attending staff in urology, to identify variables that predict more severe impostorism, and to study the association of IP with burnout. SUBJECTS AND METHODS: A survey composed of the Clance Impostor Phenomenon Scale (CIPS), demographic information, practice details, and burnout levels was e-mailed to urologists via urological subspecialty societies. Survey results were analysed to identify associations between IP severity, survey respondent characteristics, and symptoms of professional burnout. This study was conducted in the United States of America. RESULTS: A total of 614 survey responses were received (response rate 11.0%). In all, 40% (n = 213) of responders reported CIPS scores qualifying as either 'frequent' or 'intense' impostorism (i.e., scores of 61-100). On multivariable analysis, female gender, fewer years in practice (i.e., 0-2 years), and lower academic rank were all independently associated with higher CIPS scores (adjusted P < 0.05). Regarding burnout, 46% of responders reported burnout symptoms. On multivariable analysis, increase in CIPS score was independently associated with higher odds of burnout (odds ratio 1.06, 95% confidence interval 1.04-1.07; P < 0.001). CONCLUSION: Impostor phenomenon is prevalent in the urological community and is experienced more severely in younger and female urologists. IP is also independently associated with burnout. Increased female representation may improve IP amongst our female colleagues. More work is needed to determine strategies that are effective in mitigating feelings of IP and professional burnout amongst urologists, particularly those earlier in their careers.

RESUMO

To explore the preference for diagnosing and treating renal colic during pregnancy among Chinese urologists. A questionnaire was designed using the Sojump® platform. WeChat, the largest social networking platform in China, was used to distribute the questionnaire to urologists at hospitals of all levels in China. In total, 110 responses were included. Of the respondents, 100.0% used ultrasound to diagnose renal colic during pregnancy, followed by magnetic resonance imaging (17.3%) and low-dose CT (3.6%). Phloroglucinol (80.9%) and progesterone (72.7%) were the most commonly used antispasmodics and analgesics. Opioid analgesics were not commonly used (12.7%). Most of the respondents (63.6%) indicated that no more than 20% of the patients needed surgical intervention. If surgery was unavoidable, 95.5% preferred temporary renal drainage, including ureteral stenting (92.7%) and percutaneous nephrostomy (2.7%). However, some respondents still preferred definitive stone treatment, such as ureteroscopy lithotripsy (3.6%) and percutaneous nephrolithotomy (0.9%). Moreover, there were no differences in the choices of urologists with different professional titles regarding diagnostic tools, most therapeutic medications, or surgical methods (p > 0.05). Ultrasound is the preferred tool for diagnosing renal colic during pregnancy. Low-dose CT is still not widely accepted. Pregnant patients with renal colic are initially treated conservatively. Urologists prefer ureteral stenting when there are clinical indications for intervention.

RESUMO

OBJECTIVES: Lack of strict indications in current guidelines have led to significant variation in management patterns of small renal masses. The impact of the urologist on the management approach for patients with small renal masses has not been explored previously. MATERIALS AND METHODS: Using the linked Surveillance, Epidemiology, and End Results-Medicare database, patients aged ≥66 years diagnosed with small renal masses from January 1, 2004 to December 31, 2013 were identified and assigned to primary urologists. Mixed-effects logistic models were used to evaluate factors associated with different management approaches, estimate urologist-level probabilities of each approach, assess management variation, and determine urologist impact on choice of approach. RESULTS: A total of 12,402 patients with 2,794 corresponding primary urologists were included in the study. At the individual urologist level, the estimated case-adjusted probability of different approaches varied markedly: nonsurgical management (mean, 12.8%; range, 4.9%-36.1%); thermal ablation (mean, 10.8%; range, 2.4%-66.3%); partial nephrectomy (mean, 30.1%; range, 10.1%-66.6%); and radical nephrectomy (mean, 40.4%; range, 17.7%-71.6%). Compared to patient and tumor characteristics, the primary urologist was a more influential measured factor, accounting for 13.6% (vs. 12.9%), 33.8% (vs. 2.1%), 15.1% (vs. 8.4%), and 13.5% (vs. 4.0%) of the variation in management choice for nonsurgical management, thermal ablation, partial nephrectomy, and radical nephrectomy, respectively. CONCLUSIONS: Significant variation exists in the management of small renal masses and appears to be driven primarily by urologist preference and practice patterns. Our findings emphasize the need for unified guidance regarding management of these masses to reduce unwarranted variation in care.
