The diagnostic value of delayed nephrograms on contrast-enhanced computed tomography has not been studied rigorously.To develop a method for quantitatively assessing delayed and diminished nephrograms (DDNs) easily at the point of care and to assess the association of DDNs with renal obstruction and renal function.Data were reviewed from 76 patients who underwent a contrast-enhanced computed tomography scan within 30 days of a technetium-99m mercaptoacetyltriglycine diuretic renal scintigraphy (MAG3-DRS) which showed at least one kidney to have normal drainage (T1/210 min) between 2010 and 2021 at a tertiary academic center.Attenuations of the renal cortex and medulla were measured using circular regions of interest. These attenuations were compared between kidneys to compute several measures of DDN in the kidney with a greater concern for obstruction. Renal parenchymal volume and anterior-posterior renal pelvis diameter (APD) were estimated using simple linear measurements. Inter-rater reliability was computed using the intraclass correlation coefficient (ICC), correlations were computed using Spearman's R, and the relationships between DDN, APD, and renal function of the subject kidney were estimated using linear regression.Measures of DDN were highly reliable between raters (ICC 0.71-0.87). DDN was almost always associated with prolonged drainage on MAG3-DRS (90-100%); however, 33-52% of patients with prolonged drainage on MAG3-DRS had no appreciable DDN, depending on the measure of the DDN chosen. All measures of DDN were associated with decreased renal function (0.001). APD did not significantly predict renal function when controlling for a DDN.DDNs on contrast-enhanced computed tomography are associated with renal obstruction and can easily and accurately be quantified at the point of care. A DDN is more closely associated with renal dysfunction than renal pelvic dilation and therefore may be useful in assessing the severity of upper tract obstruction.In this report, we confirm that a "delayed nephrogram", a classic x-ray finding thought to be associated with kidney blockage, is associated with blockage of the affected kidney. Furthermore, we show that a delayed nephrogram indicates that the affected kidney is not functioning as well as we would expect for a normal kidney of the same size. Since the severity of a delayed nephrogram predicts this decreased function better than the degree of dilation of the kidney, which is a different measurement often used to measure the severity of kidney blockage, the delayed nephrogram may be a better way of measuring the severity of kidney blockage in clinical practice.

Gender disparities in editorial board composition exist across a variety of surgical subspecialties.To investigate temporal variation in gender representation on the editorial boards of urology journals and assess the relationship between editorial board composition and female authorship.We analyzed female authorship and editorial board composition between 2002 and 2020 among eight high-impact urology journals. Female publication status was assessed using publication records retrieved from PubMed. Editorial board information was manually extracted and titles were grouped for comparison as Editor-in-Chief, mid-level editor, and consulting editors.Female representation across different editorial levels was analyzed via hierarchical logistic regression with additional terms to test for between-journal differences in overall representation and change over time. The relationship between representation on editorial boards and as publication authors was assessed at the journal level via correlation.Eight journals and 49 412 articles were analyzed. No female has held the title of Editor-in-Chief for any of these eight journals in 18 yr. Significant growth was seen for mid-level editors, whereas no growth was seen for consulting editors. Neurourology and Urodynamics and Journal of Sexual Medicine had significantly higher than average female editorial board representation (p0.05). Across the eight journals, there was a statistically significant correlation between the proportion of overall female authors and female editors (r = 0.93, 95% confidence interval 0.65-0.99). For all journals, the proportion of female contributing authors is greater than the proportion of female editorial board members.Women in urology represent a small but increasing presence as editorial board members. Clear differences exist between journals, potentially attributable to specialty-specific demographics. Despite increasing representation, no female has ever been appointed Editor-in-Chief for any of the eight journals evaluated. At the journal-specific level, a positive correlation was observed between female editorial staff and female authorship. Given the implication of both academic authorship and editorial board assignment on academic advancement, actionable changes are outlined to guide improvement in gender diversity at the journal level.Females are under-represented on the editorial boards for urology journals, although some roles have seen growth over time. Moreover, female editorial board membership is associated with representation of females among article authors. Gender disparities in both are noteworthy because they affect career paths and contribute to the gender gap in urology.

Bladder cancer prognosis and treatment are heavily dependent on accurate staging. Traditional imaging and pathologic evaluation of transurethral resection (TUR) specimens have been associated with high rates of clinical understaging at the time of radical cystectomy (RC).We describe current components and limitations of bladder cancer staging for muscle-invasive bladder cancer (MIBC), and discuss the rationale for inclusion of novel biomarkers and imaging modalities to improve diagnostic accuracy.We summarize the data informing MIBC staging accuracy using a nonsystematic review of published literature and provide expert opinion on current and emerging standards in MIBC staging.Nearly 50% of patients undergoing RC are clinically understaged preoperatively. Components of clinical staging include TUR specimen evaluation, bimanual examination under anesthesia (EUA), and cross-sectional imaging of the chest, abdomen, and pelvis. Complete endoscopic resection of visible disease with sampling of muscularis propria is indicated. While histologic features such as tumor size, focality, variant histologic differentiation, and lymphovascular invasion have prognostic utility, insufficient evidence exists to incorporate them into current staging paradigms. For primary tumor staging, conventional computed tomography (CT) has limited accuracy in differentiating non-MIBC from MIBC. Magnetic resonance imaging (MRI) has exhibited superior pT staging accuracy with the validated Vesical Imaging Reporting and Data System. Positron emission tomography (PET)/CT does not increase clinical nodal staging accuracy beyond CT or MRI, and there exists no consensus role for the use of PET in routine clinical staging.In the absence of reliable biomarkers to serve as staging adjuncts, we continue to rely heavily on basic clinical staging components-TUR with accurate pathologic evaluation, EUA, and standard cross-sectional imaging modalities. MRI shows promising accuracy and interobserver reliability for primary tumor staging.Effective clinical staging for muscle-invasive bladder cancer estimates local and systemic disease burden and can dictate eligibility for systemic therapy and/or radical cystectomy. Herein, we review the accuracy and limitations of current and emerging staging modalities.

The role of cytoreductive nephrectomy (CN) in metastatic renal cell carcinoma (mRCC) was challenged by the results of the CARMENA trial. Here we evaluate the role of CN in mRCC patients, including those receiving modern therapies.We included patients with synchronous mRCC between 2011-2020 from the de-identified nationwide Flatiron Health database. We evaluated 3 groups: systemic therapy alone, CN followed by systemic therapy (up-front CN [uCN]) and systemic therapy followed by CN (deferred CN [dCN]). The primary outcome was median overall survival (mOS) in patients receiving systemic therapy alone vs uCN. Secondary outcome was overall survival in patients receiving uCN vs dCN. First-treatment, landmark and time-varying covariate analyses were conducted to overcome immortal time bias. Weighted Kaplan-Meier curves, log-rank tests and Cox proportional hazards regressions were used to assess the effect of therapy on survival.Of 1,910 patients with mRCC, 972 (57%) received systemic therapy, 605 (32%) received uCN, 142 (8%) dCN and 191 (10%) CN alone; 433 (23%) patients received immunotherapy-based therapy. The adjusted mOS was significantly improved in first-treatment, landmark and time-varying covariate analysis (mOS 26.6 vs 14.6 months, 36.3 vs 21.1 months and 26.1 vs 12.2 months, respectively) in patients undergoing CN. Among patients receiving CN and systemic therapy, the timing of systemic therapy relative to CN was not significantly related to overall survival (HR=1.0, 95% CI 0.76-1.32, p=0.99).Our findings support an oncologic role for CN in select mRCC patients. In patients receiving both CN and systemic therapy, the survival benefit compared to systemic alone was similar for up-front and deferred CN.

We sought to automate R.E.N.A.L. (for radius, exophytic/endophytic, nearness of tumor to collecting system, anterior/posterior, location relative to polar line) nephrometry scoring of preoperative computerized tomography scans and create an artificial intelligence-generated score (AI-score). Subsequently, we aimed to evaluate its ability to predict meaningful oncologic and perioperative outcomes as compared to expert human-generated nephrometry scores (H-scores).A total of 300 patients with preoperative computerized tomography were identified from a cohort of 544 consecutive patients undergoing surgical extirpation for suspected renal cancer at a single institution. A deep neural network approach was used to automatically segment kidneys and tumors, and geometric algorithms were developed to estimate components of R.E.N.A.L. nephrometry score. Tumors were independently scored by medical personnel blinded to AI-scores. AI- and H-score agreement was assessed using Lin's concordance correlation and their predictive abilities for both oncologic and perioperative outcomes were assessed using areas under the curve.Median age was 60 years (IQE 51-68), and 40% were female. Median tumor size was 4.2 cm and 91.3% had malignant tumors, including 27%, 37% and 24% with high stage, grade and necrosis, respectively. There was significant agreement between H-scores and AI-scores (Lin's ⍴=0.59). Both AI- and H-scores similarly predicted meaningful oncologic outcomes (p0.001) including presence of malignancy, necrosis, and high-grade and -stage disease (p0.003). They also predicted surgical approach (p0.004) and specific perioperative outcomes (p0.05).Fully automated AI-generated R.E.N.A.L. scores are comparable to human-generated R.E.N.A.L. scores and predict a wide variety of meaningful patient-centered outcomes. This unambiguous artificial intelligence-based scoring is intended to facilitate wider adoption of the R.E.N.A.L. score.

To elucidate which patients with clear cell renal cell carcinoma have the highest risk for disease relapse after curative nephrectomy is challenging but is acutely relevant in the era of approved adjuvant therapies. Pathological and genetic markers were used to improve the University of California Los Angeles Integrated Staging System (UISS) for the risk stratification and prognostication of recurrence free survival (RFS).Necrosis, sarcomatoid features, Rhabdoid features, chromosomal loss 9p, combined chromosomal loss 3p14q and microvascular invasion (MVI) were tested in univariable and multivariable analyses for their ability to improve the discriminatory ability of the UISS.In the development cohort, during the median follow-up time of 43.4 months (±SD 54.1 months), 50/240 (21%) patients developed disease recurrence. MVI (HR: 2.22; p = 0.013) and the combined loss of chromosome 3p/14q (HR: 2.89; p = 0.004) demonstrated independent association with RFS and were used to improve the assignment to the UISS risk category. In the current UISS high-risk group, only 7/50 (14%) recurrence cases were correctly identified; while in the improved system, 23/50 (45%) were correctly prognosticated. The concordance index meaningfully improved from 0.55 to 0.68 to distinguish patients at intermediate risk versus high risk. Internal validation demonstrated a robust prognostication of RFS. In the external validation cohort, there was no case with disease recurrence in the low-risk group, and the mean RFS times were 13.2 (±1.8) and 8.2 (±0.8) years in the intermediate and high-risk groups, respectively.Adding MVI and combined chromosomal loss3p/14q to the UISS improves the ability to define the patient group with clear cell renal cell carcinomawho are at the highest risk for disease relapse after surgical treatment.

BACKGROUND Elicitation of patients’ preferences is an integral part of shared decision making, the recommended approach for prostate cancer decision making. However, existing decision aids for this population do not specifically focus on patients’ preferences. Healium is a brief interactive web-based decision aid that aims to elicit patient’s treatment preferences and is designed for a low health literate population. OBJECTIVE This study used a randomized controlled trial to evaluate whether Healium (designed to target preference elicitation) is as efficacious as Healing Choices (a comprehensive education and decision tool) in improving outcomes for decision-making and emotional quality of life. METHODS Patients diagnosed with localized prostate cancer who had not yet made a treatment decision were randomly assigned to the brief Healium intervention or Healing Choices, an extensive decision aid previously developed by our group that serves as a virtual information center on prostate cancer diagnosis and treatment. Assessments were completed at baseline, 6-weeks and 3-months post-baseline, and included decisional outcomes (decisional conflict, satisfaction with decision, preparation for decision-making), and emotional quality of life (anxiety/tension and depression), along with demographics, comorbidities, and health literacy. RESULTS N = 327 individuals consented to participate in the study (171 were randomized to the Healium intervention arm and 156 were randomized to Healing Choices). The majority of the sample was non-Hispanic (96%), White (76%), married (78.4%), and had an average age of 62.4 years old (SD = 6.9). Within both arms, there was a significant decrease in decisional conflict from baseline to 6-weeks post baseline (Healium, P = CONCLUSIONS Healium, our brief decision aid focusing on treatment preference elicitation, is as successful in reducing decisional conflict as our previously tested comprehensive decision aid, Healing Choices, and has the added benefit of brevity and the potential for integration into the physician consultation and electronic medical record.

Context With the addition of active surveillance and thermal ablation (TA) to the urologist’s established repertoire of partial (PN) and radical nephrectomy (RN) as first-line management options for localized renal cell carcinoma (RCC), appropriate treatment decision-making has become increasingly nuanced. Objective To critically review the treatment options for localized, nonrecurrent RCC; to highlight the patient, renal function, tumor, and provider factors that influence treatment decisions; and to provide a framework to conceptualize that decision-making process. Evidence acquisition A collaborative critical review of the medical literature was conducted. Evidence synthesis We identify three key decision points when managing localized RCC: (1) decision for surveillance versus treatment, (2) decision regarding treatment modality (TA, PN, or RN), and (3) decision on surgical approach (open vs minimally invasive). In evaluating factors that influence these treatment decisions, we elaborate on patient, renal function, tumor, and provider factors that either directly or indirectly impact each decision point. As current nomograms, based on preselected patient datasets, perform poorly in prospective settings, these tools should be used with caution. Patient decision aids are an underutilized tool in decision-making. Conclusions Localized RCC requires highly nuanced treatment decision-making, balancing patient- and tumor-specific clinical variables against indirect structural influences to provide optimal patient care. Patient summary With expanding treatment options for localized kidney cancer, treatment decision is highly nuanced and requires shared decision-making. Patient decision aids may be helpful in the treatment discussion.

While multiple mechanisms have been hypothesized to explain the therapeutic effect of lymph node (LN) yield in patients with urothelial cell carcinoma (UCC) undergoing radical cystectomy (RC), the effect of stage migration, commonly known as the Will Rogers effect, is often discounted. We reviewed the National Cancer Database for patients with UCC undergoing RC with pathologically node-negative (pN0) disease from 2004 to 2016. We tested for an adjusted association between LN yield and overall survival using multivariable Cox proportional-hazard models. Median survival was estimated using the Kaplan-Meier method. We identified 19 939 patients with pN0 UCC treated with RC. After adjustment, patients in the highest quantile for LN yield (≥26 LNs) had a 34% lower risk of death in comparison to patients in the lowest quantile (≤5 LNs). As we increased the threshold for LN yield for dichotomization from5 to15 to25 LNs, median survival increased from 83 to 95 to 103 mo. The pN0 group with higher LN yield appeared to live longer in this analysis owing to the mathematical artifact of how patients are indexed. Resection of a greater number of negative LNs will lead to higher fidelity for pN0 cohorts being evaluated, as the likelihood of contamination by pN+ cases that were missed will be lower.A strategy to dissect a high number of lymph nodes in patients undergoing removal of their bladder for bladder cancer can be associated with side effects, and the benefit in terms of cancer control or survival remains uncertain. Urologists and their patients should engage in shared decision-making and consider the risks and benefits of more extensive lymph node dissection during surgery.

Recent advances in minimally invasive technology have compelled surgeons to perform nephrectomy with inferior vena cava thrombectomy using robotic assistance. Here, we aim to review the data comparing open versus robot-assisted nephrectomy with IVC thrombectomy, as well as review operative robotic techniques for nephrectomy with IVC thrombectomy.Over the last decade, there have been increasing reports of successful robotic-assisted IVC thrombectomy among skilled robotic surgeons, with case series detailing operative technique, as well as operative and oncologic outcomes for levels I-IV caval thrombus. While there is immense promise in the future of robotic-assisted IVC thrombectomy, further studies with direct comparison to open surgical intervention will be needed to ensure the oncologic principles and outcomes are non-inferior.

Papillary renal neoplasm with reverse polarity (PRNRP) is a newly proposed entity with distinct histology and frequent KRAS mutations. To date, 93 cases of PRNRPs have been reported. In this study, we present 7 new cases of PRNRP and review the literature. Most of the pathologic features in our 7 cases are similar to those previously reported cases. However, all 7 of our cases showed at least partial cystic changes, which was not stressed in prior studies. Single-nucleotide polymorphism-microarray based chromosomal analysis demonstrated no trisomy or other alteration of chromosomes 7 or 17; and no loss or other alteration of chromosome Y was detected in all 7 cases. Next-generation sequencing detected KRAS missense mutations in 4 of 7 cases. No fusion genes were detected. In summary, PRNRP is a small, well-circumscribed often encapsulated and cystic neoplasm with loose papillary formations. Cuboidal tumor cells always have eosinophilic cytoplasm and nuclei located at the pole opposite the basement membrane with a low World Health Organization (WHO)/International Society of Urologic Pathologists (ISUP) nuclear grade. The fibrovascular cores can be hyalinized or edematous. Macrophage aggregates and intracellular hemosiderin are uncommon, and no psammoma bodies or necrosis should be seen. Immunophenotypically, this tumor is always positive for CK7 and GATA3, and negative for CD117 and vimentin. CD10 and AMACR can be positive, but often weakly and focally. PRNRP often has KRAS mutations, however, only 32% of cases have chromosomal abnormalities in chromosomes 7, 17, and Y. No recurrences, metastases, or tumor-related deaths have been reported following complete resection.

Adrenocortical carcinoma (ACC) is a very rare endocrine cancer and is associated with a poor prognosis. There is a paucity of randomized clinical trials for this rare disease. We aimed to perform a systematic review of the literature on systemic therapy options in different stages of ACC. A systematic review was performed using Pubmed and Embase databases according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. A total of 24 trials of systemic therapy in the treatment of ACC were identified and included in this review. Only one clinical trial in the adjuvant setting was identified, the negative phase III trial ADIUVO, which tested mitotane in low to intermediate-risk ACC patients. In the treatment of advanced ACC, cisplatin-based chemotherapy was evaluated in small and non-randomized phase II trials, and response rates ranged from 21% to 53.5%. The phase III trial FIRM-ACT compared etoposide, doxorubicin, cisplatin, and mitotane versus treatment with streptozotocin and mitotane and showed no difference in OS, but higher RR and PFS were reported with the multi-drug regimen. Six clinical trials of immunotherapy and seven studies of targeted therapy in advanced ACC were included, with modest activity and no phase 3 trials were identified. Treatment recommendations of ACC are based on retrospective and small studies with limited systemic therapy options. International and multi-center collaboration is essential to expand clinical research and improve outcomes.
