RESUMEN
OBJECTIVE: To study the effect of ERAS on a textbook outcome (TO) after elective renal surgery. PATIENTS AND METHODS: Retrospective study of all patients who underwent a robot-assisted laparoscopic partial or radical nephrectomy or robot-assisted laparoscopic radical nephroureterectomy in Medisch Spectrum Twente (MST), Enschede, the Netherlands. In total, 277 patients were included. 66 patients from 2018 to 2021 (pre-ERAS group) and 211 patients from 2021 to 2023 (ERAS group). TO is a maximum of two nights in the hospital after surgery, no severe complications during or after surgery ≥ grade IIIb, no blood transfusions, no intensive care, no readmissions, and no mortality within 30 days after surgery. Comparisons were made between the pre-ERAS and ERAS groups using unpaired t-test, Mann-Whitney U test, the chi-squared test or Fisher's exact test. Multivariate logistic regression was used to adjust for possible confounding. RESULTS: TO was significantly (p = 0.005) better in the ERAS group (TO = 76.8%) compared to the pre-ERAS group (TO = 59.1%). Compared to a pre-ERAS patient, the adjusted odds ratio for achieving a TO as an ERAS patient is 2.1 (95% CI 1.15-3.78). CONCLUSIONS: The implementation of ERAS showed a positive effect on the TO of elective renal surgery patients.

Patients with end stage renal disease (ESRD) are at high risk of developing upper tract urothelial carcinoma (UTUC). Due to high recurrence rate of UTUC in contralateral kidney and ureter, and high risk of complications related to surgery and anesthesia, whether it's necessary to remove both kineys and ureters at one time remains in debate. We utilized Taiwanese UTUC Registry Database to valuate the difference of oncological outcomes and perioperative complications between patients with ESRD with unilateral and bilateral UTUC receiving surgical resection. Patients with ESRD and UTUC were divided into three groups, unilateral UTUC, previous history of unilateral UTUC with metachronous contralateral UTUC, and concurrent bilatetral UTUC. Oncological outcomes, perioperative complications, and length of hospital stays were investiaged. We found that there is no diffence of oncological outcomes including overall survival, cancer specific survival, disease free survival and bladder recurrence free survival between these three groups. Complication rate and length of hospital stay are similar. Adverse oncological features such as advanced tumor stage, lymph node involvement, lymphovascular invasion, and positive surgical margin would negatively affect oncological outcomes.

CONTEXT: Radical nephroureterectomy (RNU) with bladder cuff resection is the standard treatment in patients with high-risk upper tract urothelial cancer (UTUC). However, it is unclear which specific surgical technique may lead to improve oncological outcomes in term of intravesical recurrence (IVR) in patients with UTUC. OBJECTIVE: To evaluate the efficacy of surgical techniques and approaches of RNU in reducing IVR in UTUC patients. EVIDENCE ACQUISITION: Three databases were queried in January 2024 for studies analyzing UTUC patients who underwent RNU. The primary outcome of interest was the rate of IVR among various types of surgical techniques and approaches of RNU. EVIDENCE SYNTHESIS: Thirty-one studies, comprising 1 randomized controlled trial and 1 prospective study, were included for a systematic review and meta-analysis. The rate of IVR was significantly lower in RNU patients who had an early ligation (EL) of the ureter compared to those who did not (HR: 0.64, 95% CI: 0.44-0.94, p = 0.02). Laparoscopic RNU significantly increased the IVR compared to open RNU (HR: 1.28, 95% CI: 1.06-1.54, p < 0.001). Intravesical bladder cuff removal significantly reduced the IVR compared to both extravesical and transurethral bladder cuff removal (HR: 0.65, 95% CI: 0.51-0.83, p = 0.02 and HR: 1.64, 95% CI: 1.15-2.34, p = 0.006, respectively). CONCLUSIONS: EL of the affected upper tract system, ureteral management, open RNU, and intravesical bladder cuff removal seem to yield the lowest IVR rate in patients with UTUC. Well-designed prospective studies are needed to conclusively elucidate the optimal surgical technique in the setting of single post-operative intravesical chemotherapy.

BACKGROUND: Prolonged laparoscopic nephroureterectomy (LNU) for upper tract urothelial cancer (UTUC) can increase the frequency of intravesical recurrence after surgery. Therefore, it is important for urological surgeons to have knowledge on preoperative risk factors for prolonged LNU. However, few studies have investigated the risk factors for prolonged LNU. We hypothesized that the quantity of perirenal fat affects the pneumoretroperitoneum time (PRT) of retroperitoneal LNU (rLNU). This study aimed to investigate the preoperative risk factors for prolonged PRT during rLNU. METHODS: We reviewed the data of 115 patients who underwent rLNU for UTUC between 2013 and 2021. The perirenal fat thickness (PFT) observed on preoperative computed tomography (CT) images was used to evaluate the perinephric fat quantity. Preoperative risk factors for PRT during rLNU were analyzed using logistic regression models. The cutoff value for PRT was determined based on the median time.The cutoff values for fat-related factors influencing PRT were defined according to receiver operating characteristic curve analysis. RESULTS: The median PRT for rLNU was 182 min (interquartile range, 155-230 min). The cutoff values of posterior, lateral, and anterior PFTs were 15 mm, 24 mm, and 6 mm, respectively. Multivariate analysis revealed that a posterior PFT ≥ 15 mm (odds ratio [OR], 2.72; 95% confidence interval, 1.04-7.08; p = 0.0410) was an independent risk factor for prolonged PRT. CONCLUSIONS: Thick posterior PFT is a preoperative risk factor for prolonged PRT during rLNU. For patients with UTUC and thick posterior PFT, surgeons should develop optimal surgical strategies, including the selecting an expert surgeon as a primary surgeon and the selecting transperitoneal approach to surgery or open surgery.

OBJECTIVE: Disease recurrence, particularly intravesical recurrence (IVR) after radical nephroureterectomy (RNU) for upper tract urothelial carcinoma (UTUC), is common. We investigated whether violations of onco-surgical principles before or during RNU, collectively referred to as surgical violation (SV), were associated with survival outcomes. Material and methods: Data from a consecutive series of patients who underwent RNU for UTUC 2001-2012 at Skåne University Hospital Lund/Malmö were collected. Preoperative insertion of a nephrostomy tube, opening the urinary tract during surgery or refraining from excising the distal ureter were considered as SVs. Survival outcomes in patients with and without SV (IVR-free [IVRFS], disease-specific [DSS] and overall survival [OS]) were assessed using multivariate Cox regression analyses (adjusted for tumour stage group, prior or concomitant bladder cancer, comorbidity and preoperative urinary cytology). RESULTS: Of 150 patients, 47 (31%) were subjected to at least one SV. Overall, SV was not associated with IVRFS (HR 0.81, 95% CI 0.4-1.6) but with worse DSS (HR 1.9, 95% CI 1.03-3.7) and OS (HR 1.9, 95% CI 1.2-3) in multivariable analysis. Additional analyses with a broader definition of SV including also preoperative instrumentation of the upper urinary tract (ureteroscopy and/or double J stenting) showed similar outcomes for DSS (HR 2.1, 95% CI 1.1-4.3). CONCLUSION: Worse survival outcomes, despite no difference in IVR, for patients that were subjected to the violation of sound onco-surgical principles before or during RNU for UTUC strengthen the notion that adhering to such principles is a cornerstone in upper tract urothelial cancer surgery.

To assess the oncologic efficacy and safety of robot-assisted approach to radical nephroureterectomy (RARNU) in geriatric versus younger patients with upper tract urothelial carcinoma (UTUC). A single-center, retrospective cohort study was conducted from 2009 to 2022 of 145 patients (two cohorts: < 75 and ≥ 75 years old) with non-metastatic UTUC who underwent RARNU. Primary endpoint was UTUC-related recurrence of disease during surveillance (bladder-specific and metastatic). Safety was assessed according to 30-day, modified Clavien-Dindo (CD) classifications (Major: C.D. III-V). Survival estimates were performed using Kaplan-Meier method. There were 89 patients < 75 years (median 65 years) and 56 patients ≥ 75 years (median 81 years). Comparing the young versus geriatric cohorts: median follow-up 38 vs 24 months (p = 0.03, respectively) with similar 3-year bladder-specific recurrence survival (60% vs 67%, HR 0.70, 95% CI [0.35, 1.40], p = 0.31) and metastasis-free survival (79% vs 70%, HR 0.71, 95% CI [0.30, 1.70], p = 0.44). Expectedly, the younger cohort had a significant deviation in overall survival compared to the geriatric cohort at 1-year (89% vs 76%) and 3-years (72% vs 41%; HR 3.29, 95% CI [1.88, 5.78], p < 0.01). The 30-day major (1% vs 0) and minor complications (8% vs 14%, p = 0.87). Limitations include retrospective study design of a high-volume, single-surgeon experience. Compared to younger patients with UTUC, geriatric patients undergoing RARNU have similar oncologic outcomes at intermediate-term follow-up with no increased risk of 30-day perioperative complications. Thus, age alone should not be used to disqualify patients from definitive surgical management of UTUC with RARNU.

BACKGROUND: The role of kidney-sparing surgery in patients with high-risk upper urinary tract urothelial carcinoma is controversial. The present study aimed to assess oncological and functional outcomes of robot-assisted distal ureterectomy in patients with high-risk distal ureteral tumors. METHODS: The ROBUUST 2.0 multicenter international (2015-2022) dataset was used for this retrospective cohort analysis. High-risk patients with distal ureteral tumors were divided based on type of surgery: robot-assisted distal ureterectomy or robot-assisted nephroureterectomy. A survival analysis was performed for local recurrence-free survival, distant metastasis-free survival, and overall survival. After adjusting for clinical features of the high-risk prognostic group, Cox proportional hazard model was plotted to evaluate significant predictors of time-to-event outcomes. RESULTS: Overall, 477 patients were retrieved, of which 58 received robot-assisted distal ureterectomy and 419 robot-assisted nephroureterectomy, respectively, with a mean (±SD) follow-up of 29.6 months (±2.6). The two groups were comparable in terms of baseline features. At survival analysis, no significant difference was observed in terms of recurrence-free survival (P=0.6), metastasis-free survival (P=0.5) and overall survival (P=0.7) between robot-assisted distal ureterectomy and robot-assisted nephroureterectomy. At Cox regression analysis, type of surgery was never a significant predictor of worse oncological outcomes. At last follow-up patients undergoing robot-assisted distal ureterectomy had significantly better postoperative renal function. CONCLUSIONS: Comparable outcomes in terms of recurrence-free survival, metastasis-free survival, and overall survival between robot-assisted distal ureterectomy and robot-assisted nephroureterectomy patients, and better postoperative renal function preservation in the former group were observed. Kidney-sparing surgery should be considered as a potential option for selected patients with high-risk distal ureteral UTUC.

BACKGROUND: The effect of radical nephroureterectomy (RNUx) on postoperative renal function in patients diagnosed with upper tract urothelial carcinoma (UTUC) has not been thoroughly explored. METHODS: We conducted a retrospective analysis including 785 patients who underwent RNUx for UTUC. We assessed the preoperative and postoperative estimated glomerular filtration rates (eGFRs) and factors related to the decline in eGFR. Additionally, we examined the effect of comorbidities (diabetes or hypertension) on the postoperative eGFR at 1 year. Cox proportional hazard models were employed to investigate the clinical effect of RNUx on oncological outcomes, including non-urothelial tract recurrence-free survival (NUTRFS), cancer-specific survival (CSS), and overall survival (OS). RESULTS: The median preoperative and postoperative eGFR levels were 54.7 and 40.6 ml/min/1.73 m2 respectively. The proportions of patients with preoperative and postoperative eGFR ≥60 mL/min/1.73 m2 were 35.9% and 5.1%, respectively. The median decline in the eGFR after surgery was 26.8%. Patients with preoperative eGFR <60 ml/min/1.73 m2 demonstrated significantly lower odds of a postoperative decline in eGFR of 25% or more. The effect of comorbidities on postoperative eGFR at 1 year was significant (Pâ¯=â¯0.048). The 3-year NUTRFS, CSS, and OS rates were 72.9%, 85.2%, and 81.5%, respectively. Preoperative chronic kidney disease was an independent factor associated with inferior NUTRFS, CSS, and OS. CONCLUSION: Different degrees of impairment of renal function occur among UTUC patients. Only 5.1% of patients retain a postoperative eGFR ≥60 ml/min/1.73 m2. Preoperative renal impairment was linked to reduced odds of postoperative eGFR decrease and associated with survival. In addition, the presence of comorbidities had a significant effect on the decline in eGFR. These findings emphasize the importance of developing evidence-based perioperative treatment strategies for UTUC patients with impaired renal function.

INTRODUCTION: Robot-assisted nephroureterectomy (RANU) for upper urinary tract urothelial carcinoma is typically performed via the transperitoneal approach because of limited surgical space. However, a retroperitoneal approach may be preferable in patients with a history of abdominal surgery or in those in whom pelvic lymph node dissection is unnecessary. MATERIALS AND SURGICAL TECHNIQUES: RANU via the retroperitoneal approach was selected for two patients diagnosed with high-grade upper urothelial carcinoma with a history of abdominal surgery. Nephrectomy was performed in the 90° flank position, and the bed was tilted at 20°. The retroperitoneal space was extended, and the robot trocar was subsequently repositioned in the left lower quadrant. After redocking the robot, the distal ureter was dissected, and the bladder cuff was resected en bloc along with the kidney and the ureter. Neither patient had any complications within 3 months postoperatively. DISCUSSION: By devising a new technique for trocar placement, total retroperitoneal RANU without repositioning was possible, even in a small patient.

PURPOSE: To evaluate the efficacy of intravesical (IVe) Bacillus Calmette-Guerin (BCG) to treat non-muscle invasive bladder cancer (NMIBC) recurrences in patients who have previously undergone nephroureterectomy for upper tract urothelial carcinoma (UTUC). METHODS: We performed a single institution retrospective review of patients who underwent nephroureterectomy for UTUC from 2009 to 2021. Patients who subsequently developed NMIBC treated with transurethral resection followed by IVe BCG were included in the study group. A control cohort was formed by retrospective review of patents with primary NMIBC treated with BCG during the same period. Patients in the control cohort were matched by stage of bladder cancer at a 2:1 ratio of control to study subjects. Demographic data, pathology of bladder tumors prior to and following BCG, use of maintenance BCG (mBCG), time to recurrence, time to progression, progression to cystectomy, and progression to metastatic disease were collected on all patients. Descriptive statistics were utilized to compare the 2 groups. The primary outcome was progression to muscle invasive disease. Secondary outcomes included intravesical recurrence free survival, disease free survival, and progression to metastatic disease. Univariable and multivariable logistic regression analysis was performed to elucidate independent variables associated with bladder tumor recurrence. Multivariable Cox regression analysis was used to assess the impact of prior UTUC on time to bladder tumor recurrence. RESULTS: One-hundred and ninety-one patients underwent nephroureterectomy at our institution from 2009 to 2021 for UTUC. Twenty-five patients were identified to have subsequently developed NMIBC recurrences treated with inductions BCG. The control group was comprised of 50 patients with primary NMIBC matched by stage of bladder cancer for which BCG was indicated in the study group. Median (interquartile range [IQR]) follow-up was significantly longer in the control group relative to the study group (64.8 [50.1-85.6] vs 25 months [17-35]; Pâ¯=â¯0.001). There were no significant differences in demographics between the study and control groups. The rate of progression to muscle invasive disease was 17% vs 0% in the study group and control group respectively (Pâ¯=â¯0.0521). History of UTUC was associated with increased risk of intravesical bladder tumor recurrence post BCG on multivariable analysis (HR 2.5; Pâ¯=â¯0.017) and Kaplan Meier survival analysis (Pâ¯=â¯0.039). The mean time to bladder tumor recurrence after treatment with BCG was significantly worse in the study group at (7.9 vs. 23.9 months; Pâ¯=â¯0.0322). Similarly, the rate of progression to metastatic disease was worse in the study group (24% vs 2%; Pâ¯=â¯0.0047). Overall disease-free survival was also noted to be significantly worse on Kaplan Meier survival analysis in the study group (Pâ¯=â¯0.0074). No statistically significant differences in the stage grade of bladder tumor recurrence, grade of bladder tumor recurrence, or rate of progression to cystectomy were identified. CONCLUSIONS: Our study suggests reduced efficacy of BCG for NMIBC in patients with a history of UTUC. Patients in this population should be counseled accordingly. Research into alternative treatments for bladder tumor recurrence and more aggressive prophylactic regimens after nephroureterectomy for prevention of bladder tumor recurrence in this population is encouraged.

OBJECTIVE: Localized Upper Urinary Tract Urothelial Carcinoma (UTUC) is an uncommon cancer typically detected at an advanced stage. Currently, radical nephroureterectomy (RNU) with bladder cuff excision is the standard treatment for high-risk UTUC. This meta-analysis aims to evaluate the 5-year overall and cancer-specific survival and bladder recurrence rates in studies comparing endoscopic kidney-sparing surgeries (E-KSS) with RNU in localized UTUC. EVIDENCE ACQUISITION: We performed a literature search on 20th April 2023 through PubMed, Web of Science, and Scopus. The PICOS model was used for study inclusion: P: adult patients with localized UTUC; I: E-KSS. C: RNU; O: primary: overall survival (OS); secondary: cancer-specific survival (CSS), bladder recurrence rate, and metastasis-free survival (MFS). S: retrospective, prospective, and randomized studies. EVIDENCE SYNTHESIS: Overall, 11 studies involving 2284 patients were eligible for this meta-analysis, 737 in the E-KSS group and 1547 in the RNU group. E-KSS showed a similar overall 5-year OS between E-KSS and RNU, and for low-grade tumors, while 5-year OS favored RNU for high-grade tumors (RR 1.84, 95% CI 1.26-2.69, p = 0.002). No difference emerged for 5-year CSS between the two groups, even when the results were stratified for low- and high grade tumors. Bladder recurrence rate and 5-year MFS were also similar between the two groups. CONCLUSIONS: Our review showed that E-KSS is a viable option for patients with localized UTUC with non-inferior oncological outcomes as compared with RNU, except for 5-year OS in high-grade tumors which favoured RNU.

INTRODUCTION: Upper tract urothelial carcinoma (UTUC) is a rare disease accounting only for 5%-10% of urothelial carcinoma (UC). For localized high-risk disease, radical nephroureterectomy (RNU) is the standard of care. While minimally invasive (MIS) RNU has not been shown to decisively improve overall survival (OS) compared to open surgery, MIS RNU has been associated with reduced hospital length of stay (LOS), blood transfusion requirements and improved recovery, which are important considerations when treating older patients. The purpose of this study is to examine trends in surgical approach selection and outcomes of open vs. MIS RNU in patients aged ≥80 years. METHODS: Using the National Cancer Database (NCDB), patients aged ≥80 years who underwent open or MIS (either robotic or laparoscopic) RNU were identified from 2010 to 2019. Demographic, patient-related, and disease-specific factors associated with either open or MIS RNU were assessed using multivariate logistic regression models. Survival analysis was conducted using Kaplan-Meier plots and Cox-proportional hazard regression. Inverse probability of treatment weighting (IPTW) was utilized to adjust for confounding variables. Survival analysis was also conducted on the IPTW adjusted cohort using Kaplan-Meier plots and Cox-proportional hazard regression. RESULTS: 5,687 patients were identified, with 1,431 (25.2%) and 4,256 (74.8%) patients undergoing open and MIS RNU respectively. The proportion of RNU performed robotically has increased from 12.5% in 2010 to 50.4% in 2019. MIS was associated with a shorter hospital LOS (4.7 days versus 5.9 days, SMD 23.7%). Multivariate analysis revealed that MIS was associated with a significant reduction in 90-day mortality (OR: 0.571; 95%CI: 0.34-0.96, Pâ¯=â¯0.033) and improved median OS (53.8 months [95%CI: 50.9-56.9] vs 42.35 months [95%CI: 38.6-46.8], P < 0.001) compared to open surgery. IPTW-adjusted survival analysis revealed improved median OS with MIS when compared to open surgery, with a survival benefit of 46.1 months (95%CI: 40.2-52.4 months) versus 37.7 months (95%CI: 32.6-46.5 months, Pâ¯=â¯0.0034) respectively. IPTW-adjusted cox proportional hazard analysis demonstrated that MIS was significantly associated with reduced mortality (HR 0.76, 95%CI: 0.66-0.87, P < 0.001). CONCLUSION: In octogenarians undergoing RNU, MIS is associated with improved median OS and 90-day mortality.

In the field of urology, robotic surgery has gained rapid and wide acceptance as a standard surgical approach in the majority of major surgeries over the last decade. To date, the da Vinci surgical system has been the dominant platform in robotic surgery; however, several newly developed robotic systems have recently been introduced in routine clinical practice. Of these, hinotori, the first made-in-Japan robotic system, is characterized by various unique and attractive features different from the existing system, and the use of this system has gradually increased mainly in urologic cancer surgeries, including radical prostatectomy, partial nephrectomy, radical nephrectomy, and radical nephroureterectomy. This review initially describes detailed characteristics of hinotori, then summarizes the early experience with urologic cancer surgeries using hinotori at our institution, and finally discusses the future prospects of robotic surgery using hinotori, considering problems associated with the use of this robotic system.

Purpose: To investigate the feasibility, safety, and efficacy of the KangDuo-Surgical Robot-01 (KD-SR-01) system for robot-assisted radical nephroureterectomy (RARNU). Materials and Methods: This prospective, single-center, single-arm clinical study of patients with upper tract urothelial carcinoma (UTUC) was conducted from August 2022 to July 2023 using the KD-SR-01 system. The perioperative and follow-up data were prospectively recorded. The National Aeronautics and Space Administration task load index was calculated to present ergonomics. The technique was described in detail. Results: A total of 13 patients underwent RARNU. None of the cases conversed to laparoscopic procedure or open procedure. The median docking time and console time were 524 seconds (range 139-963 seconds) and 102.2 minutes (range 55.3-249.3 minutes), respectively. The median estimated blood loss was 40 mL (range 10-100 mL). None of the patients required intraoperative blood transfusion. The median postoperative hospital stay was 4 days (range 2-7 days). Intraoperative or postoperative complications (Clavien-Dindo grade I) occurred in nine patients. The surgeon task load index global score achieved 1.05 ± 1.86. Three patients received the single-docking technique, demonstrating similar perioperative results compared with patients with redocking. The study is registered at www.chictr.org.cn (ChiCTR2200056672). Conclusions: The KD-SR-01 system was feasible, safe, and effective for RARNU.

BACKGROUND: The optimal oncologic surveillance in patients with upper tract urothelial carcinoma (UTUC) elected for conservative treatment is still a matter of debate. METHODS: Patients elected for endoscopic treatment of UTUC were followed up according to EAU guidelines recommendations after treatment. Bladder cancer recurrence-free survival (BCa-RFS), UTUC recurrence-free survival (UTUC-RFS), radical nephroureterectomy-free survival (RNU-FS), and cancer-specific survival (CSS) were estimated using the Kaplan-Meier method. The crude risks of BCa and UTUC recurrences over time were estimated with the Locally Weighted Scatterplot Smoothing method. RESULTS: Overall, 54 and 55 patients had low- and high-risk diseases, respectively. Median follow-up was 46.9 (IQR: 28.7-68.7) and 36.9 (IQR: 19.8-60.1) months in low and high-risk patients, respectively. In low-risk patients, BCa recurrence risk was more than 20% at 24 months follow-up. At 60 months, time point after which cystoscopy and imaging should be interrupted, the risk of BCa recurrence and UTUC recurrence were 14% and 7%, respectively. In high-risk patients, the risk of BCa and UTUC recurrence at 36 months was approximately 40% and 10%, respectively. Conversely, at 60 months, the risk of bladder recurrence and UTUC recurrence was 28% and 8%, respectively. CONCLUSIONS: For low-risk patients, cystoscopy should be performed semi-annually until 24 months, while upper tract assessment should be obtained up to 60 months, as per current EAU guidelines recommendations. For high-risk patients, upper tract assessment should be intensified to semi-annually up to 36 months, then obtained yearly. Conversely, cystoscopy should be ideally performed semi-annually until 60 months and yearly thereafter.

PURPOSE: We aimed to determine the prognostic value of α-hydroxybutyrate dehydrogenase (α-HBDH) in upper tract urothelial carcinoma (UTUC) patients after radical nephroureterectomy (RNU). MATERIALS AND METHODS: We retrospectively enrolled the data of 544 UTUC patients at West China Hospital from May 2003 to June 2019. Cancer-specific survival (CSS) was the endpoint of interest. The optimal cutoff value of α-HBDH was identified by X-Tile program. After propensity score matching (PSM), we utilized KaplanâMeier curves to estimate survival and Cox proportional hazard model for risk assessment. A nomogram was built based on the results of multivariate analysis, and calibration curve, time-dependent receiver operating characteristic (ROC) curves and decision curve analysis were also performed to evaluate the predictive accuracy. RESULTS: Overall, 394 and 150 patients were divided into the α-HBDH-low group and α-HBDH -high group at the cutoff value of 158 U/L, respectively. After PSM, the two groups were well matched for all confounding factors. High α-HBDH was associated with inferior CSS (P = 0.006), and preoperative α-HBDH was an independent predictor for CSS (HR: 1.36; 95% CI:1.08, 1.80), especially in localized UTUC patients (HR: 2.04; 95% CI:1.11, 3.74). Furthermore, the nomogram based on α-HBDH achieved great predictive ability for CSS with areas under the curves of 0.800 and 0.778 for 3-year and 5-year CSS, respectively. CONCLUSION: Serum α-HBDH was a novel and reliable biomarker for predicting survival outcomes in UTUC patients after RNU but should be further explored.

OBJECTIVE: The European POUT III randomized controlled trial provided level-one evidence that adjuvant platinum-based chemotherapy is the standard of care following nephroureterectomy (RNU) for locally invasive or node-positive upper tract urothelial carcinoma. We aim to assess this European randomized controlled trial's generalizability (external validity) to a North American cohort, using a nationwide database. MATERIALS AND METHODS: To compare trial patients with those seen in real-world practice, we simulated the trial inclusion criteria using data from the National Cancer Database (NCDB). We identified patients with histologically confirmed transitional cell carcinoma who underwent RNU. The available demographic characteristics of the NCDB cohort were compared with the POUT III trial cohort using Chi-squared test. RESULTS: The NCDB cohort (nâ¯=â¯3,380) had a significantly higher proportion of older patients (age ≥ 80: 23.5% vs. 5%), and more males (68% vs. 56.2%) than the POUT cohort (Table 1, both p < 0.001). Additionally, the rate of advanced nodal disease was higher in the NCDB (N1 9.6%, N2 9.3%) than in the POUT (N1 6%, N2 3%) cohort (p < 0.001). A more extensive lymph node dissection was performed in NCDB vs. POUT patients (node≥10 10.9% vs. 3%, p < 0.001). Sensitivity analysis removing all subjects with a Charlson Comorbidity Index > 0 did not change the significance of any results. CONCLUSIONS: While the primary disease stage was similar, the rate of advanced nodal disease was significantly higher in NCDB, which might be explained partially by the more extensive lymph node dissection performed in the latter. These differences warrant caution when applying the POUT III findings to North American patients.

BACKGROUND AND OBJECTIVE: Venous thromboembolism (VTE) is a significant predictor of worse postoperative morbidity in cancer surgeries. No data have been available for patients with preoperative VTE and upper tract urothelial carcinoma (UTUC) undergoing radical nephroureterectomy (RNU). Our aim was to assess the impact of a preoperative VTE diagnosis on perioperative outcomes in the RNU context. METHODS: Patients aged 18 yr or older with a UTUC diagnosis undergoing RNU were identified in the Merative Marketscan Research deidentified databases between 2007 and 2021. Multivariable logistic regression adjusted by relevant perioperative confounders was used to investigate the association between a diagnosis of VTE prior to RNU and 90-d complication rates, postoperative VTE, rehospitalization, and total costs. A sensitivity analysis on VTE severity (pulmonary embolism [PE] and/or deep venous thrombosis [DVT]) was examined. KEY FINDINGS AND LIMITATIONS: Within the investigated cohort of 6922 patients, history of any VTE preceding RNU was reported in 568 (8.21%) cases, including DVT (n = 290, 51.06%), PE (n = 169, 29.75%), and superficial VTE (n = 109, 19.19%). The history of VTE before RNU was predictive of higher rates of complications, the most prevalent being respiratory complications (odds ratio [OR]: 1.78, 95% confidence interval [CI]: 1.43-2.22). Preoperative VTE was found to be associated with an increased risk of VTE following RNU (OR: 14.3, 95% CI: 11.48-17.82), higher rehospitalization rates (OR: 1.26, 95% CI 1.01-1.56) other than home discharge status (OR: 1.44, 95% CI: 1.18-1.77), and higher costs (OR 1.42, 95% CI: 1.20-1.68). Limitations include the retrospective nature and the use of an insurance database that relies on accurate coding and does not include information such as pathologic staging. CONCLUSIONS AND CLINICAL IMPLICATIONS: The presented findings will contribute to the counseling process for patients. These patients may benefit from enhanced pre/postoperative anticoagulation. More research is needed before the following results can be used in the clinical setting. PATIENT SUMMARY: Patients aged 18 yr or older with an upper tract urothelial carcinoma (UTUC) diagnosis undergoing radical nephroureterectomy (RNU) were identified in the Merative Marketscan Research deidentified databases between 2007 and 2021. Multivariable logistic regression adjusted by relevant perioperative confounders was used to investigate the association between a diagnosis of venous thromboembolism (VTE) prior to RNU and 90-d complication rates, postoperative VTE, rehospitalization, and total costs. A sensitivity analysis on VTE severity (pulmonary embolism and/or deep venous thrombosis) was examined. The presented findings will contribute to the counseling of patients with UTUC and preoperative VTE.
