Telemedicine in urologic oncology care: Will telemedicine exacerbate disparities?

INTRODUCTION: Disparities in prostate, bladder, and kidney cancer outcomes are associated with access to care. Telemedicine can improve access but may be underutilized by certain patient populations. Our objective was to determine if the patient populations who suffer worse oncologic outcomes are the same as those who are less likely to use telemedicine. METHODS: Using an institutional database, we identified all prostate, bladder and kidney cancer encounters from March 14, 2020 to October 31, 2021 (n = 15,623; n = 4, 14; n = 3,830). Telemedicine was used in 13%, 8%, and 12% of these encounters, respectively. We performed random effects modeling analysis to examine patient and provider characteristics associated with telemedicine use. Adjusted odds ratios (OR) and 95% confidence intervals (CI) were reported as measures of association. RESULTS: Among prostate, bladder, and kidney cancer patients, Black patients had lower odds of a telemedicine encounter (OR 0.51, 95% CI 0.37-0.69; OR 0.22, 95% CI 0.07-0.70; OR 0.46, 95% CI 0.24-0.86), and patients residing in small and isolated small rural towns areas had higher odds of a telemedicine encounter (OR 1.44, 95% CI 1.09-1.91; OR 2.12, 95% CI 1.14-3.94; OR 1.89, 95% CI 1.12-3.19). Compared to providers in practice ≤5 years, providers in practice for 6 to 15 years had significantly higher odds of a telemedicine encounter for prostate and bladder cancer patients (OR 4.10, 95% CI 1.4511.58; OR 3.42, 95% CI 1.09-10.77). CONCLUSION: The lower rates of telemedicine use among Black patients could exacerbate pre-existing disparities in prostate, bladder, and kidney cancer outcomes.

Exhaled Breath Analysis Using Selected Ion Flow Tube Mass Spectrometry and Disease Severity in Heart Failure.

Exhaled breath volatile organic compounds (VOCs) are elevated in heart failure (HF). The ability of VOCs to predict long term cardiovascular mortality and morbidity has not been independently verified. In 55 patients admitted with acute decompensated heart failure (ADHF), we measured exhaled breath acetone and pentane levels upon admission and after 48 h of diuresis. In a separate cohort of 51 cardiac patients undergoing cardiopulmonary exercise testing (CPET), we measured exhaled breath acetone and pentane levels before and at peak exercise. In the ADHF cohort, admission acetone levels correlated with lower left ventricular ejection fraction (LVEF, r = -0.297, p = 0.035). Greater weight loss with diuretic therapy correlated with a greater reduction in both acetone levels (r = -0.398, p = 0.003) and pentane levels (r = -0.309, p = 0.021). In patients with above-median weight loss (≥4.5 kg), patients demonstrated significantly greater percentage reduction in acetone (59% reduction vs. 7% increase, p < 0.001) and pentane (23% reduction vs. 2% reduction, p = 0.008). In the CPET cohort, admission acetone and pentane levels correlated with higher VE/VCO2 (r = 0.39, p = 0.005), (r = 0.035, p = 0.014). However, there were no significant correlations between baseline or peak exercise acetone and pentane levels and peak VO2. In longitudinal follow-up with a median duration of 33 months, patients with elevated exhaled acetone and pentane levels experienced higher composite adverse events of death, ventricular assist device implantation, or orthotopic heart transplantation. In patients admitted with ADHF, higher exhaled breath acetone levels are associated with lower LVEF and poorer outcomes, and greater reductions in exhaled breath acetone and pentane tracked with greater weight loss. Exhaled acetone and pentane may be novel biomarkers in heart failure worthy of future investigation.

A Multipronged Intervention to Reduce Readmissions and Readmission Intensity After Radical Cystectomy.

OBJECTIVE: To develop a multipronged, evidence-based protocol to reduce readmission risk and readmission intensity, as represented by the duration of the index readmission, after radical cystectomy. MATERIALS AND METHODS: A per-protocol study was performed. The protocol included preoperative nutritional supplementation, early stent removal, and a follow-up phone call within 4-5days of discharge. The preprotocol period was from February 1, 2020 to July 31, 2021 and the postprotocol period was from December 1, 2020 to November 31, 2021. Using multivariate regression models, we compared outcomes among patients treated with radical cystectomy before and after protocol initiation. RESULTS: We identified 70 preprotocol patients and 126 postprotocol patients. After adjusting for age, sex, BMI, and frailty score, there was a significant reduction in 90-day readmission intensity (7 vs 5days; P = .048) among postprotocol patients. CONCLUSION: After implementation of an evidence-based protocol for patients undergoing radical 90-day readmission intensity decreased significantly. This protocol may move the needle forward on reducing readmissions, but a larger randomized trial is needed.

Utilizing a Questionnaire to Implement a Risk-based Antibiotic Prophylaxis Protocol for Transrectal Prostate Biopsy.

OBJECTIVE: To develop and evaluate a risk-based antibiotic prophylaxis protocol for patients undergoing transrectal prostate biopsy. METHODS: We created a risk-based protocol for antibiotic prophylaxis before transrectal prostate biopsy. Patients were screened for infection risk-factors with a self-administered questionnaire. The protocol was implemented from January 1, 2020 to March 31, 2020. We compared patient risk-factors, antibiotic regimens, and 30-day infection rates for patients undergoing transrectal prostate biopsies during the intervention and for a 3-month period before the intervention. RESULTS: There were 116 prostate biopsies in the preintervention group and 104 in the intervention group. Although there was no significant difference in the number of high-risk patients between the 2 groups (48% vs 55%; P = .33), the percentage of patients treated with augmented prophylaxis decreased from 74% to 45% (P = 0.03). The duration of antibiotic administration and the median number of doses prescribed also decreased significantly. Despite significant decreases in antibiotic use, there were no differences in infection rates (5% vs 5%; P = .90) or sepsis rates (1% vs 2%; P = .60). CONCLUSION: We developed a risk-based protocol for prophylactic antibiotics before prostate biopsy. The protocol was associated with less antibiotic use but did not lead to an increase in infectious complications.

Large Variations in the Prices of Urologic Procedures at Academic Medical Centers 1 Year After Implementation of the Price Transparency Final Rule.

Importance: Patients with urologic diseases often experience financial toxicity, defined as high levels of financial burden and concern, after receiving care. The Price Transparency Final Rule, which requires hospitals to disclose both the commercial and cash prices for at least 300 services, was implemented to facilitate price shopping, decrease price dispersion, and lower health care costs. Objective: To evaluate compliance with the Price Transparency Final Rule and to quantify variations in the price of urologic procedures among academic hospitals and by insurance class. Design, Setting, and Participants: This was a cross-sectional study that determined the prices of 5 common urologic procedures among academic medical centers and by insurance class. Prices were obtained from the Turquoise Health Database on March 24, 2022. Academic hospitals were identified from the Association of American Medical Colleges website. The 5 most common urologic procedures were cystourethroscopy, prostate biopsy, laparoscopic radical prostatectomy, transurethral resection of the prostate, and ureteroscopy with laser lithotripsy. Using the corresponding Current Procedural Terminology codes, the Turquoise Health Database was queried to identify the cash price, Medicare price, Medicaid price, and commercial insurance price for these procedures. Exposures: The Price Transparency Final Rule, which went into effect January 1, 2021. Main Outcomes and Measures: Variability in procedure price among academic medical centers and by insurance class (Medicare, Medicaid, commercial, and cash price). Results: Of 153 hospitals, only 20 (13%) listed a commercial price for all 5 procedures. The commercial price was reported most often for cystourethroscopy (86 hospitals [56%]) and least often for laparoscopic radical prostatectomy (45 hospitals [29%]). The cash price was lower than the Medicare, Medicaid, and commercial price at 24 hospitals (16%). Prices varied substantially across hospitals for all 5 procedures. There were significant variations in the prices of cystoscopy (χ23 = 85.9; P = .001), prostate biopsy (χ23 = 64.6; P = .001), prostatectomy (χ23 = 24.4; P = .001), transurethral resection of the prostate (χ23 = 51.3; P = .001), and ureteroscopy with laser lithotripsy (χ23 = 63.0; P = .001) by insurance type. Conclusions and Relevance: These findings suggest that, more than 1 year after the implementation of the Price Transparency Final Rule, there are still large variations in the prices of urologic procedures among academic hospitals and by insurance class. Currently, in certain situations, health care costs could be reduced if patients paid out of pocket. The Centers for Medicare & Medicaid Services may improve price transparency by better enforcing penalties for noncompliance, increasing penalties, and ensuring that hospitals report prices in a way that is easy for patients to access and understand.

Comparison of AUA and phoenix definitions of biochemical failure following permanent brachytherapy for prostate cancer.

PURPOSE: To compare biochemical recurrence free survival (BCRFS) and cancer-specific survival (CSS) after brachytherapy using the AUA and the Phoenix definitions. METHODS AND MATERIALS: 2634 men with T1-T4N0M0 prostate cancer were treated with brachytherapy with or without neoadjuvant hormonal therapy or external beam radiation therapy. Five, 10, and 15- year BCRFS and CSS were estimated with Kaplan-Meier estimates with log rank. Multivariate analysis of survival was performed with Cox regression analysis. RESULTS: Median age was 66, follow-up was 8.6 years, and prostate specific antigen was 6.9. Overall, 11.1% (n = 293) of patients experienced Phoenix BCR and 17.48% (n = 457) experienced AUA BCR. The rates of AUA BCR and Phoenix BCR were significantly different at 5 and 10-years but not at 15 years. Patients treated with BED ≤ 200 Gy were more likely to experience AUA BCR (22.5% vs. 12.4%, OR 1.44, p < 0.001) and Phoenix BCR (14.3% and 8.3%, OR 1.37, p < 0.001) than patients treated with a BED > 200 Gy. CONCLUSIONS: Compared to the Phoenix definition, the AUA definition of BCR after brachytherapy is associated with significantly worse BCRFS for the first 15 years after treatment. Receiving a BED > 200, which cannot be achieved without the addition of brachytherapy, is associated with better BCRFS and CSS. Our findings reaffirm the importance of dose in the management of prostate cancer.

Large Variation in International Prescribing Rates of Opioids After Robotic Prostatectomy.

OBJECTIVE: To compare international opioid prescribing patterns for patients undergoing robotic assisted laparoscopic prostatectomy. To our knowledge, this is the first study to assess international opioid prescribing trends among urologists. METHODS: An anonymous Web-based survey assessing the frequency and quantity of opioid prescriptions for robotic assisted laparoscopic prostatectomy was designed using Qualtrics software. The survey was distributed to urologists internationally via Twitter and email in early 2021. Prescribing patterns were analyzed based on country of practice in three groups: United States, Canada, and all other countries. RESULTS: 160 participants from 26 countries completed the survey including the United States (51%), Greece (19%), Canada (9%), Israel (3.1%). The percentage of providers prescribing post-discharge opioids significantly differed between Canada, the United States, and other countries (86%, 63%, and 11%, respectively, P <.0001). There was a significant difference between years of experience in those who provide opioids compared to those who do not (8 years vs 5 years, P = .0004). The average morphine milligram equivalents (MME) provided in those who did prescribe opioids was greatest in the United States but was not significantly different between groups (mean MME: United States 58 mg, Canada 46 mg, all others 54 mg; P = .63). Attending physicians prescribed more MME than trainees (residents, fellows) on average (attending mean MME = 75 mg, trainee mean MME = 40 mg, P = .017). CONCLUSION: Opioid prescriptions after robotic assisted prostatectomy are common in North America and used sparingly in the rest of the world.

Robotic assisted radical cystectomy versus open radical cystectomy: a review of what we do and don't know.

Radical cystectomy (RC) is the gold standard treatment for muscle-invasive and high-risk, noninvasive bladder cancer. Since 2003, robot-assisted radical cystectomy (RARC) has been gaining popularity. Metanalyses show that the primary advantage of RARC is less blood loss and the primary advantage of open radical cystectomy (ORC) is shorter operative times. There do not appear to be significant differences in complications, cancer-related outcomes or survival between the two approaches. Cost analyses comparing RARC and ORC are complicated by the often-ill-defined distinction between the cost to the hospital versus the cost to payors. However, it is likely that for both hospitals and payors, RARC is cost effective at high-volume centers. It is feasible that in the future, increased experience with RARC will lead to improved outcomes and justify the use of RARC over ORC.

Gender Differences in Incidence, Diagnosis, Treatments, and Outcomes in Clinically Localized Bladder and Renal Cancer.

OBJECTIVE: To review differences in bladder and renal cell cancer (RCC) incidence, diagnosis, treatment, and outcomes between men and women, and to summarize the evidence that explains these differences. METHODS: A review of the current literature was performed using PubMed and Google Scholar. RESULTS: The incidence of bladder cancer and RCC is higher in men. Historically higher smoking rates among men explain some but not all of the difference in incidence. Hormonal and genetic factors also contribute. In bladder cancer, the androgen receptor and estrogen receptor beta have been associated with gender and tumor characteristics. In RCC the relationships are less well defined. In both bladder cancer and RCC, differences in gene mutation patterns among men and women, particularly among genes located on the X-chromosome, have also been identified. Differences in the work-up and treatment of men and women with bladder cancer and RCC also contribute to gender disparities. CONCLUSION: Research to better delineate how the hormonal axis and genetics contribute to disparities in bladder cancer and RCC incidence and outcomes will allow for more individualized medicine. Appreciation of barriers to diagnosis and treatment will identify opportunities to improve patient care.

Robotic-Assisted Partial Nephrectomy and Adrenalectomy: Case of a Pheochromocytoma Invading into Renal Parenchyma.

Although upper pole renal masses and adrenal masses can usually be distinguished on cross-sectional imaging, large masses can obscure the boundaries between the kidney and adrenal gland. We describe a unique case of an adrenal pheochromocytoma in a 42-year-old female who was referred for robotic partial nephrectomy. During the procedure, the patient developed severe hypertension. The case was aborted, and the workup revealed pheochromocytoma. After appropriate pretreatment, the patient underwent a successful robotic adrenalectomy and partial nephrectomy. Therefore, we recommend screening patients with hypertension and large upper pole masses for pheochromocytoma to better direct preoperative management.

Robotic partial nephrectomy: The current status.

INTRODUCTION: Since its introduction, robotic partial nephrectomy (RPN) has become increasingly popular, in part as a result of several advances in technique. The purpose of this paper is to review these techniques as well as the perioperative, functional, and oncologic outcomes after RPN and compare these outcomes to those after laparoscopic partial nephrectomy (LPN) and open partial nephrectomy (OPN). METHODS: A literature review was performed to identify papers and meta-analyses that compared outcomes after RPN to OPN or LPN. All meta-analyses were included in this review. RESULTS: Technical advances that have contributed to improved outcomes after RPN include the first-assistant sparing technique, the sliding clip technique, early unclamping, and selective arterial clamping. All five meta-analyses that compared LPN to RPN found that RPN was associated with a shorter warm ischemia time (WIT), but that there were no differences in estimated blood loss (EBL) or operative times. Those meta-analyses that compared intraoperative and postoperative complications, conversion to open or radical nephrectomy, length of stay (LOS), and postoperative estimated glomerular filtration rate (eGFR) either found no difference or favored RPN. Four meta-analyses compared RPN to OPN. All four found that EBL, LOS, and postoperative complications favor RPN. There were no significant differences in intraoperative complications, conversion to radical nephrectomy, or positive surgical margin rates. One meta-analysis found that eGFR was better after RPN. Operative time and WIT generally favored OPN. CONCLUSIONS: Several techniques have been described to improve outcomes after RPN. We believe that the literature shows that RPN is as good if not better than both LPN and OPN and has become the preferred surgical approach.

BPH: Why Do Patients Fail Medical Therapy?

PURPOSE OF REVIEW: In this article, we review why patients may fail medical therapy for benign prostatic hyperplasia (BPH) and by doing so, gain a better understanding of the disease process and how to optimize the care of these patients. RECENT FINDINGS: A growing body of literature has attempted to better characterize the various mechanisms by which patients develop BPH as well as identify predictors of disease progression and treatment failure. BPH is a heterogenous disease process. A more personalized approach to treatment, including patient selection for medical or surgical management, would allow us to optimize patient care.

Focal Ablative Therapy for Renal Cell Carcinoma in Transplant Allograft Kidneys.

OBJECTIVE: To evaluate outcomes after focal ablative therapy for renal cell carcinoma (RCC) in transplant allograft kidneys. METHODS: After institutional review board approval, patients with a history of RCC in a transplanted allograft kidney who underwent focal ablative therapy were identified. Complete chart reviews were performed and the relevant data were extracted for cumulative analysis. RESULTS: Six patients were treated with focal ablative therapy for RCC in a transplanted allograft kidney at our institutional between 2010 and 2017. Masses were diagnosed at a median of 8 years (range 1 month-8 years) after transplantation. Median mass size was 3 cm. Three patients were treated with microwave ablation, 1 with percutaneous irreversible electroporation, 1 with laparoscopic cryoablation, and 1 with open cryoablation. Median follow-up was 45 months (range 8-61 months). The median creatinine level was 1.65 before ablation and 1.58 1 year after ablation. No patients required dialysis after ablation. No patients developed local recurrence during the follow-up period. However, 1 patient developed lymph node metastases 4 years after ablation. Two patients died during follow-up of other causes. At the time of death both patients had functioning grafts. CONCLUSION: Focal ablative therapies are a feasible, renal-sparing intervention for the management of RCC in renal allografts at intermediate-term follow-up.
