Abstract
Introduction: Endoscopic tumor ablation of upper tract urothelial carcinoma (UTUC) allows for tumor control with the benefit of renal preservation but is impacted by intraoperative visibility. We sought to develop a computer vision model for real-time, automated segmentation of UTUC tumors to augment visualization during treatment. Materials and Methods: We collected 20 videos of endoscopic treatment of UTUC from two institutions. Frames from each video (N = 3387) were extracted and manually annotated to identify tumors and areas of ablated tumor. Three established computer vision models (U-Net, U-Net++, and UNext) were trained using these annotated frames and compared. Eighty percent of the data was used to train the models while 10% was used for both validation and testing. We evaluated the highest performing model for tumor and ablated tissue segmentation using a pixel-based analysis. The model and a video overlay depicting tumor segmentation were further evaluated intraoperatively. Results: All 20 videos (mean 36 ± 58 seconds) demonstrated tumor identification and 12 depicted areas of ablated tumor. The U-Net model demonstrated the best performance for segmentation of both tumors (area under the receiver operating curve [AUC-ROC] of 0.96) and areas of ablated tumor (AUC-ROC of 0.90). In addition, we implemented a working system to process real-time video feeds and overlay model predictions intraoperatively. The model was able to annotate new videos at 15 frames per second. Conclusions: Computer vision models demonstrate excellent real-time performance for automated upper tract urothelial tumor segmentation during ureteroscopy.

Endoscopic intervention versus radical nephroureterectomy for the management of localized upper urinary tract urothelial carcinoma: a systematic review and meta-analysis of comparative studies. World J Urol 2024; 42:318.

Abstract
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.

Endoscopic excision versus radical nephroureterectomy for non-muscle invasive upper tract urothelial carcinoma: A population-based large cohort study. Heliyon 2023; 9:e22408. [PMID: 38107280 PMCID: PMC10724554 DOI: 10.1016/j.heliyon.2023.e22408] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2023] [Revised: 11/07/2023] [Accepted: 11/10/2023] [Indexed: 12/19/2023] Open
Abstract
Background As an important kidney-sparing treatment for upper urothelial carcinoma (UTUC), whether endoscopic excision can be performed without sacrificing oncologic outcomes remains indefinite. This study aimed to investigate the prevalence and efficacy of endoscopic excision, in patients with non-muscle invasive UTUC (NMIUTUC) and compare them to those of radical nephroureterectomy (RNU). Methods Using the Surveillance, Epidemiology, and End Results database, we reviewed 4347 cases with NMIUTUC (cTis/Ta/T1-N0-M0,≤ 5.0 cm) between 2004 and 2020. Surgical treatment modalities included endoscopic excision and RNU. Propensity score matching analysis was used to minimize the selection bias between endoscopic excision and RNU, selecting 1:1 matched patients in the two group. Results A total of 794 patients with NMIUTUC were included after matching (397:397). Patients who underwent endoscopic excision had worse survival outcomes compared with those of patients who underwent RNU (5-year OS: 65.3 % vs. 80.3 %, p < 0.0001; 5-year DSS: 83.2 % vs. 94.0 %, p = 0.00021). After stratification by anatomical sites, the effect of endoscopic excision for NMI renal pelvis cancer was worse than RNU (5-year OS, 62.9 % vs. 82.8 %; 5-year DSS, 78.8 % vs. 91.6 %), while in NMI ureteral cancer, there is no statistically significant difference in OS and DSS between endoscopic excision and RNU. Further stratification according to tumor grade revealed equivalent tumor control effects of endoscopic excision and RNU in low-grade NMI ureteral cancer (5-year OS: 67.7 % vs. 72.5 %, p = 0.23; 5-year DSS: 87.2 % vs. 93.1 %, p = 0.17); while for renal pelvis tumor and high-grade ureteral tumor, endoscopic excision was related with significantly inferior prognosis. Conclusions Only for low-grade NMI ureteral cancer, endoscopic excision and RNU are oncologically equivalent, indicating that endoscopic excision might be an effective option for low-grade NMI ureteral cancer. This result needs to be further verified in randomized controlled trials.

The importance of second-look ureteroscopy implementation in the conservative management of upper tract urothelial carcinoma. World J Urol 2023; 41:2743-2749. [PMID: 37668716 DOI: 10.1007/s00345-023-04577-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2023] [Accepted: 08/11/2023] [Indexed: 09/06/2023] Open
Abstract
PURPOSE The purpose of the study was to evaluate the effect of second-look ureteroscopy (SU) in the endoscopic operative work-up of patients with upper tract urothelial carcinoma (UTUC). MATERIALS AND METHODS Patients with UTUC who underwent SU between 2016 and 2021 were included. Cancer detection rate (CDR) at SU was defined as endoscopic visualization of tumor. The effect of SU on recurrence-free survival (RFS), radical nephroureterectomy-free survival (RNU-FS), bladder cancer-free survival (BC-FS), and cancer-specific survival (CSS) was estimated using the Kaplan-Meier method. Multivariate logistic regression analysis (MLR) assessed predictors of negative SU. Finally, we evaluated the effect of SU timing on oncological outcomes, classifying SUs as "early" (≤ 8 weeks) and "late" (> 8 weeks). RESULTS Overall, 85 patients underwent SU. The CDR at SU was 44.7%. After a median follow-up was 35 (IQR: 15-56) months, patients with positive SU had a higher rate of UTUC recurrence (47.4% vs 19.1%, p = 0.01) and were more frequently radically treated (34.2% vs 8.5%, p = 0.007). Patients with high-grade disease (hazard ratio [HR]: 3.14, 95% CI 1.18-8.31; p = 0.02) had a higher risk of UTUC recurrence, while high-grade tumor (HR: 3.87, 95%CI 1.08-13.77; p = 0.04) and positive SU (HR: 4.56, 95%CI 1.05-22.81; p = 0.04) were both predictors of RNU. Low-grade tumors [odds ratio (OR): 5.26, 95%CI 1.81-17.07, p = 0.003] and tumor dimension < 20 mm (OR: 5.69, 95%CI 1.48-28.31, p = 0.01) were predictors of negative SU. Finally, no significant difference emerged regarding UTUC recurrence, RNU, BC-FS, and CSM between early vs. late SUs (all p > 0.05). CONCLUSIONS SU may help in identifying patients with UTUC experiencing an early recurrence after conservative treatment. Patients with low-grade and small tumors are those in which SU could be safely postponed after 8 weeks.

Abstract
PURPOSE To review the latest evidence on the modern techniques and outcomes of kidney-sparing surgeries (KSS) in patients with upper tract urothelial carcinoma (UTUC). METHODS A comprehensive literature search on the study topic was conducted before 30 April 2023 using electronic databases including PubMed, MEDLINE, and EMBASE. A narrative overview of the literature was then provided based on the extracted data and a qualitative synthesis of the findings. RESULTS KSS is recommended for low- as well as select high-risk UTUCs who are not eligible for radical treatments. Endoscopic ablation is a KSS option that is associated with similar oncological outcomes compared with radical treatments while preserving renal function in well-selected patients. The other option in this setting is distal ureterectomy, which has the advantage of providing a definitive pathological stage and grade. Data from retrospective studies support the superiority of this approach over radical treatment with similar oncological outcomes, albeit in select cases. Novel chemoablation agents have also been studied in the past few years, of which mitomycin gel has received FDA approval for use in low-risk UTUCs. CONCLUSION KSSs are acceptable approaches for patients with low- and select high-risk UTUCs, which preserve renal function without compromising the oncological outcomes.

Abstract
OBJECTIVE To identify clinicopathological or radiological factors that may predict a diagnosis of upper urinary tract urothelial cell carcinoma (UTUC) to inform which patients can proceed directly to radical nephroureterectomy (RNU) without the delay for diagnostic ureteroscopy (URS). PATIENTS AND METHODS All consecutive patients investigated for suspected UTUC in a high-volume UK centre between 2011 and 2017 were identified through retrospective analysis of surgical logbooks and a prospectively maintained pathology database. Details on clinical presentation, radiological findings, and URS/RNU histopathology results were evaluated. Multivariate regression analysis was performed to evaluate predictors of a final diagnosis of UTUC. RESULTS In all, 260 patients were investigated, of whom 230 (89.2%) underwent URS. RNU was performed in 131 patients (50.4%), of whom 25 (9.6%) proceeded directly without URS - all of whom had a final histopathological diagnosis of UTUC - and 15 (11.5%) underwent RNU after URS despite no conclusive histopathological confirmation of UTUC. Major surgery was avoided in 77 patients (33.5%) where a benign or alternative diagnosis was made on URS, and 14 patients (6.1%) underwent nephron-sparing surgery. Overall, 178 patients (68.5%) had a final diagnosis of UTUC confirmed on URS/RNU histopathology. On multivariate logistic regression analysis, a presenting complaint of visible haematuria (hazard ratio [HR] 5.17, confidence interval [CI] 1.91-14.0; P = 0.001), a solid lesion reported on imaging (HR 37.8, CI = 11.7-122.1; P < 0.001) and a history of smoking (HR 3.07, CI 1.35-6.97; P = 0.007), were predictive of a final diagnosis of UTUC. From this cohort, 51 (96.2%) of 53 smokers who presented with visible haematuria and who had a solid lesion on computed tomography urogram had UTUC on final histopathology. CONCLUSION We identified specific factors which may assist clinicians in selecting which patients may reliably proceed to RNU without the delay of diagnostic URS. These findings may inform a prospective multicentre analysis including additional variables such as urinary cytology.

Oncologic and Safety Outcomes for Endoscopic Surgery Versus Radical Nephroureterectomy for Upper Tract Urothelial Carcinoma: An Updated Systematic Review and Meta-analysis. Eur Urol Focus 2022; 9:236-240. [PMID: 36463089 DOI: 10.1016/j.euf.2022.11.016] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2022] [Revised: 10/27/2022] [Accepted: 11/14/2022] [Indexed: 12/02/2022]
Abstract
We systematically reviewed the literature and summarized oncologic and safety outcomes for endoscopic management (EM) compared to radical nephroureterectomy (RNU) for patients with upper tract urothelial carcinoma (UTUC). Studies comparing oncologic and/or safety results for EM versus RNU in patients with UTUC were included in our review. Overall, 13 studies met the criteria, and five studies were included in a meta-analysis using adjusted hazard ratios (HRs) for overall survival (OS), cancer-specific survival (CSS), and bladder recurrence-free survival (BRFS). EM was associated similar OS (HR 1.27, 95% confidence interval [CI] 0.75-2.16), CSS (HR 1.37, 95% CI 0.99-1.91), and BRFS (HR 0.98, 95% CI 0.61-1.55) to RNU, while 28-85% of patients treated with EM experienced upper tract recurrence across the studies. EM required more interventions with a higher cumulative risk of complications and lower likelihood of renal preservation. In summary, EM for low-grade UTUC had comparable survival outcomes to RNU at the cost of higher local recurrence rates resulting in a need for long-term rigorous surveillance and repeated interventions. PATIENT SUMMARY: For selected cases of cancer in the upper urinary tract, surgical treatment via a telescope inserted through the urethra or the skin (endoscope) results in cancer control outcomes that are comparable to those after removal of the kidney and ureter. However, because of its higher rate of local recurrence, this approach requires repeated endoscopic treatment sessions. Patients should be well informed about these issues to help in shared decision-making.

Abstract
Purpose We retrospectively analyzed the oncological outcomes of T3 or G3 distal ureteral urothelial carcinoma (DUUC) underwent partial ureterectomy (PU) followed by adjuvant radiotherapy (ART). Methods From January 2008 to September 2019, clinical data from a total of 221 patients with pathologic T3 or G3 who underwent PU or RNU at our hospital were analyzed. 17 patients of them were treated with PU+ART, 72 with PU alone and 132 with radical nephroureterectomy (RNU). Clinicopathologic outcomes were evaluated. Survival was assessed using the Kaplan-Meier method. Cox regression addressed recurrence-free survival (RFS), metastasis-free survival (MFS), cancer specific survival (CSS) and overall survival (OS). Results Median age and follow-up time were 68 (IQR 62-76) years old and 43 (IQR 28-67) months, respectively. In univariate and multivariable analyses, no lymph node metastasis(LNM) and ART were independent prognostic factors of RFS (p=0.031 and 0.016, respectively). ART significantly improved 5-year RFS compared with the PU alone, (67.6% vs. 39.5%, HR: 2.431, 95%CI 1.210-4.883, p=0.039). There was no statistical difference in 5-year RFS between PU+ART and RNU groups (67.6% vs. 64.4%, HR=1.113, 95%CI 0.457-2.712, p=0.821). Compared with PU alone or RNU, PU+ART demonstrated no statistical difference in 5-year MFS (PU+ART 73.2%, PU 57.2%, RNU69.4%), CSS (70.7%, 55.1%, 76.6%, respectively), and OS (70.7%, 54.1%, 69.2%, respectively). Conclusions For distal ureteral urothelial carcinoma patients with T3 or G3, adjuvant radiotherapy could significantly improve recurrence-free survival compared with partial ureterectomy alone. There was no significant difference between survival outcomes of PU+ART and radical nephroureterectomy.

[PMID: 34527577 PMCID: PMC8435863 DOI: 10.3389/fonc.2021.699801] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2021] [Accepted: 08/10/2021] [Indexed: 11/29/2022] Open
Abstract
Purpose To evaluate the value of F-18 FDG PET/CT in the differentiation of malignant and benign upper urinary tract-occupying lesions. Patients and Methods 64 patients with upper urinary tract-occupying lesions underwent F-18 FDG PET/CT at RenJi Hospital from January 2015 to February 2019 in this retrospective study. Of the 64 patients, 50 patients received nephroureterectomy or partial ureterectomy; 14 patients received ureteroscopy and biopsy. The comparisons of PET/CT parameters and clinical characteristics between malignant and benign upper urinary tract-occupying lesions were investigated. Results Of the 64 patients, 49 were found to have malignant tumors. Receiver operating characteristic analysis determined the lesion SUVmax value of 6.75 as the threshold for predicting malignant tumors. There were significant associations between malignant and benign upper urinary tract-occupying lesions and SUVmax of lesion (P<0.001), lesion size (P<0.001), and patient age (P=0.011). Multivariate analysis showed that SUVmax of lesion (P=0.042) and patient age (P=0.009) as independent predictors for differentiation of malignant from benign upper urinary tract-occupying lesions. There was a significant difference in tumor size between the positive (SUVmax >6.75) and negative (SUVmax ≤6.75) PET groups in 38 of the 49 patients with malignant tumors. Conclusion The SUVmax of lesion and patient age is associated with the nature of upper urinary tract-occupying lesions. F-18 FDG PET/CT may be useful to distinguish between malignant and benign upper urinary tract-occupying lesions and determine a suitable therapeutic strategy.

A 25-year perspective on advances in an understanding of the biology, evaluation, treatment and future directions/challenges of urothelial cancer. Urol Oncol 2021; 39:528-547. [PMID: 34332848 DOI: 10.1016/j.urolonc.2021.05.036] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2021] [Revised: 05/25/2021] [Accepted: 05/28/2021] [Indexed: 11/16/2022]
Abstract
The Urologic Oncology Journal was founded 25 years ago and we reviewed the literature since that time in the area of urothelial cancer to see the progress and pitfalls we have made over this time period. A comprehensive literature search was conducted by the authors involved who are all actively involved in research, clinical trials, and treatment for urothelial cancer and the results were summarized over the past 25 years. The field of urothelial cancer has evolved tremendously in the last 25 years with the incorporation of molecular subtyping, novel imaging, immunotherapy, and robotic surgery. However, treatments such as BCG and radical cystectomy have remained steadfast over the last 25 years. Although we have a better understanding of the biology of bladder cancer, we still have a long way from being able to cure patients with bladder cancer and eliminate morbidity from treatments. Nevertheless, considerable progress has been made since the founding of the Urologic Oncology Journal 25 years ago.

Abstract
Laser technology is widely used in urological surgery, from lithotripsy, prostate surgery to en-bloc resection of tumours. While Holmium:YAG has been widely employed over the last two decades, in recent years, there has been a surge of interest in Thulium Fiber Laser (TFL), which offers theoretical advantages of better water absorption and lower stone ablation thresholds. A systematic review was conducted to assess the evidence from clinical research on TFL's application for lithotripsy and prostate surgery. It identified 357 articles and 8 (1506 patients) were selected, of which 4 clinical studies each investigated TFL enucleation of prostate (ThuFLEP) and TFL lithotripsy. For flexible ureteroscopic lithotripsy (FURSL), stone ablation settings ranged from 0.1-4 J, and 7-300 Hz, mean operative time ranged from 23.4-39.8 minutes and lasing time ranged from 1.2-10 minutes. For stone dusting in percutaneous nephrolithotomy (PCNL), settings of 0.2 J and 125-200 Hz were found to be optimal. For ThuFLEP, all studies showed a significant improvement in IPSS (International Prostate Symptom Score), urinary flow rate (Qmax), quality of life measures, and post-void residual volume, with mean operative time ranging from 67-104.5 minutes. Our review shows that there is limited evidence on the use and clinical outcomes of TFL. ThuFLEP might suggest equivalence to the widely used HoLEP in the available evidence so far. TFL lithotripsy shows promising results but further prospective, randomized trials are required to properly assess its usability, clinical effectiveness and standardisation of the settings for successful adoption of the technology.

Ureteroscopic Cryoablation for Patients with Upper Tract Urothelial Carcinoma of a Solitary Kidney: A Porcine Model and Our Pilot Clinical Experience. Ann Surg Oncol 2021; 28:9201-9208. [PMID: 34129151 PMCID: PMC8591015 DOI: 10.1245/s10434-021-10233-5] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2021] [Accepted: 05/09/2021] [Indexed: 12/12/2022]
Abstract
Purpose To investigate the safety and efficacy of ureteroscopic cryoablation by a liquid-nitrogen system in a porcine model and for patients with upper tract urothelial carcinoma (UTUC) of a solitary kidney. Methods In the animal experiment, the right-sided ureter was frozen in nine pigs. Eight were randomly assigned to two different groups according to the freezing duration of 60 or 90 s. The other one was designed to receive a 10-min freeze. The treated ureters were harvested at 30 min, 2 days, 4 weeks, and 3 months after cryoablation for histological evaluation. After the animal study, we conducted a pilot clinical trial that enrolled six patients who were diagnosed with UTUC of a solitary kidney and received therapeutic management with ureteroscopic cryoablation at our center. Perioperative adverse events and oncological outcomes were evaluated. Results In the porcine model, the liquid-nitrogen system was capable of forming a therapeutic ice ball which infiltrated the full-thickness ureter and induced apoptosis and necrosis from mucosa to lamina muscularis through histological examination. In the clinical trial, cryoablation was successfully performed under ureteroscopy in all the patients, without intraoperative ureteral perforation, avulsion, or active hemorrhage. No recurrence in situ was observed during a median follow-up period of 12.5 months. Hydronephrosis and ureteral stricture was observed in one patient and was managed with ureteroscopic balloon dilation. Conclusions Ureteroscopic cryoablation induced by liquid nitrogen is a promising technique for conservative management of UTUC with benefits of improving local tumor control and preservation of a solitary kidney.

Accuracy and Clinical Utility of a Tumor Grade- and Stage-based Predictive Model in Localized Upper Tract Urothelial Carcinoma. Eur Urol Focus 2021; 8:761-768. [PMID: 34053904 DOI: 10.1016/j.euf.2021.05.002] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2021] [Revised: 04/21/2021] [Accepted: 05/12/2021] [Indexed: 11/17/2022]
Abstract
BACKGROUND Among various clinicopathologic factors used to identify low-risk upper tract urothelial carcinoma (UTUC), tumor grade and stage are of utmost importance. The clinical value added by inclusion of other risk factors remains unproven. OBJECTIVE To assess the performance of a tumor grade- and stage-based (GS) model to identify patients with UTUC for whom kidney-sparing surgery (KSS) could be attempted. DESIGN, SETTING, AND PARTICIPANTS In this international study, we reviewed the medical records of 1240 patients with UTUC who underwent radical nephroureterectomy. Complete data needed for risk stratification according to the European Association of Urology (EAU) and National Comprehensive Cancer Network (NCCN) guidelines were available for 560 patients. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Univariable and multivariable logistic regression analyses were performed to determine if risk factors were associated with the presence of localized UTUC. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of the GS, EAU, and NCCN models in predicting pathologic stage were calculated. RESULTS AND LIMITATIONS Overall, 198 patients (35%) had clinically low-grade, noninvasive tumors, and 283 (51%) had ≤pT1disease. On multivariable analyses, none of the EAU and NCCN risk factors were associated with the presence of non-muscle-invasive UTUC among patients with low-grade and low-stage UTUC. The GS model exhibited the highest accuracy, sensitivity, and negative predictive value among all three models. According to the GS, EAU, and NCCN models, the proportion of patients eligible for KSS was 35%, 6%, and 4%, respectively. Decision curve analysis revealed that the net benefit of the three models was similar within the clinically reasonable range of probability thresholds. CONCLUSIONS The GS model showed favorable predictive accuracy and identified a greater number of KSS-eligible patients than the EAU and NCCN models. A decision-making algorithm that weighs the benefits of avoiding unnecessary kidney loss against the risk of undertreatment in case of advanced carcinoma is necessary for individualized treatment for UTUC patients. PATIENT SUMMARY We assessed the ability of three models to predict low-grade, low-stage disease in patients with cancer of the upper urinary tract. No risk factors other than grade assessed on biopsy and stage assessed from scans were associated with better prediction of localized cancer. A model based on grade and stage may help to identify patients who could benefit from kidney-sparing treatment of their cancer.

Abstract
INTRODUCTION Hematuria can be a distressing and debilitating complication of urothelial carcinoma (UC) of the kidney for patients who are not candidates for surgery or ureteroscopic ablation. We retrospectively assessed the efficacy, tolerability, and safety of stereotactic body radiotherapy (SBRT) for controlling gross hematuria in this patient population. MATERIALS AND METHODS Institutional Review Board (IRB)-approved review of the records, laboratory values, pathology, and imaging of 8 consecutive patients treated with SBRT over a 5-year period for uncontrolled gross hematuria caused by UC of the renal pelvis or calyces. RESULTS Therapy was delivered in 3 to 5 treatments over 1 to weeks. Individual treatments lasted an average of 17.2 minutes. No patient experienced treatment-related pain, vomiting, or diarrhea. All enjoyed cessation of bleeding within a week of completing therapy. Hematuria recurred in 2 patients in 4 and 22 months. Of the patients who have not re-bled, 3 expired of metastatic disease or co-morbidities, and 3 remain alive up to 6 years posttreatment. Of patients who have survived longer than a year, creatinine has changed by -0.05 to +0.35, and estimated glomerular filtration rate has fallen by an average of 22%. No patient has required dialysis. CONCLUSIONS SBRT appears to be an effective and well-tolerated means of palliating gross hematuria secondary to UC of the renal pelvis or calyces in patients who are unfavorable candidates for nephrectomy or ureteroscopic ablation. Treatment was associated with a moderate decline in renal function.

Endoscopic exploration directly impacts clinical decision making in the management of patients with suspected upper tract urothelial carcinoma following radical cystectomy. Urol Oncol 2021; 39:732.e1-732.e8.

Abstract
OBJECTIVES To assess whether the use of endoscopic exploration (EE) as a routine diagnostic tool in patients with clinical suspicion of upper tract urothelial carcinoma (UTUC) following radical cystectomy (RC) significantly impacts management decision-making and to describe the oncological outcomes of patients with UTUC after RC. MATERIALS AND METHODS We performed a retrospective review of medical records of patients with suspicion of UTUC after RC between 2000 and 2019. Patient demographics, clinicopathological features, treatments, and outcomes were analyzed. RESULTS We identified 60 patients with suspicion of UTUC. After diagnostic work-up, 16 were submitted to radical nephroureterectomy (RNU) and 44 underwent diagnostic EE. After EE, a further 18/44 (40.9%) were submitted to RNU, while no evidence of tumor was found in 12 (27.3%) and the remaining 12 (27.3%) underwent endoscopic treatment (ET). Thus, in 24/44 (54.5%) patients the primary treatment strategy, i.e., RNU, was altered. Twenty-nine (85.3%) of the 34 patients who underwent RNU had high-grade tumors and 16 (47%) had the muscle-invasive disease. In the ET group, 6 (50%) had high-grade tumors and 10 (83.4%) had tumors less than 2 cm. The 5-year estimated recurrence-free survival and cancer-specific survival were, respectively, 58.4% and 45.6% in the RNU group and 25% and 80.8% in the ET group. CONCLUSION EE significantly impacts clinical decision-making in patients with suspicion of UTUC after RC, resulting in a change in treatment strategy in approximately half of the patients. UTUC following RC has a poor prognosis and although RNU is the gold standard, ET could be considered in a selected group of patients.

Abstract
Our aim was to analyze the clinical and survival differences among patients who underwent the two main treatment modalities, endoscopic ablation and radical nephroureterectomy. This study examined all patients who had undergone endoscopic management and RNU between Jul. 1988 and Mar. 2019 from the Taiwan UTUC registry. The inclusion criteria were low stage UTUC in RNU and all cases in endoscopic managed UTUC with a curative intent. The demographic and clinical characteristics were included for analysis. In total, 84 cases in the endoscopic group and 272 cases in the RNU group were enrolled for final analysis. The median follow-up period were 33.5 and 42.0 months in endoscopic and RNU group, respectively (p = 0.082). Comparison of Kaplan–Meier estimated survival curves between groups, the endoscopic group was associated with similar overall survival (OS), cancer specific survival (CSS), and intravesical recurrence free survival (IVRS) but demonstrated inferior disease free survival (DFS) (p = 0.188 for OS, p = 0.493 for CSS and p < 0.001 for DFS). Endoscopic management of UTUC was as safe as RNU in UTUC endemic region.

Abstract
Urothelial carcinoma of the upper urinary tract is uncommon and presents unique challenges for diagnosis and management. Nephroureterectomy has been the preferred management option, but it is associated with significant morbidity. Nephron-sparing treatments are a valuable alternative and provide similar efficacy in select cases. A PubMed literature review was performed in English language publications using the following search terms: urothelial carcinoma, upper tract, nephron-sparing, intraluminal and systemic therapy. Contemporary papers published within the last 10 years were primarily included. Where encountered, systematic reviews and meta-analyses were given priority, as were randomized controlled trials for newer treatments. Core guidelines were referenced and citations reviewed for inclusion. A summary of epidemiological data, clinical diagnosis, staging, and treatments focusing on nephron-sparing approaches to upper tract urothelial carcinoma (UTUC) are outlined. Nephron-sparing management strategies are viable options to consider in patients with favorable features of UTUC. Adjunctive therapies are being investigated but the data remains mixed. Protocol variability and dosage differences limit statistical interpretation. New mechanisms to improve treatment dwell times in the upper tracts are being designed with promising preliminary results. Studies investigating systemic therapies are ongoing but implications for nephron-sparing management are uncertain. Nephron-sparing management is an acceptable treatment modality best suited for favorable disease. More work is needed to determine if intraluminal and/or systemic therapies can further optimize treatment outcomes beyond resection alone.

Abstract
Upper urinary tract urothelial cell carcinoma (UTUC) is a rare entity. The incidence in Germany is approximately 2/100,000 with a ratio between women and men of 1:2.5. Most clinical signs are nonspecific, which is why early diagnosis is rarely successful. Computed tomography urography in combination with diagnostic ureterorenoscopy is currently the gold standard in the diagnostics of UTUC. Regarding surgical treatment, radical nephroureterectomy (RNU) with resection of a bladder cuff remains the method of choice, although the radical approach is developing towards laparoscopic/robotic or endourological procedures with preservation of kidney tissue. Due to the high recurrence rate (22-47%) of urothelial carcinoma inside the bladder, close follow-up after RNU is mandatory.

Abstract
BACKGROUND Radical nephroureterectomy (RNU) is the gold standard treatment for upper urinary tract urothelial carcinoma (UTUC); however, patients presenting with small low-grade UTUC have been treated by flexible ureteroscopic laser ablation with good outcomes. Different types of laser have been discussed in the literature including Holmium and Neodymium lasers. We aimed to assess the safety and efficacy of Thulium laser (Tm:YAG) in the ureteroscopic ablation of UTUC. METHODS A retrospective observational multicentre study of patients diagnosed with papillary UTUC between January 2015 and December 2016 was carried out. All patients underwent ureteroscopic biopsy of the UTUC followed by Tm:YAG ablation. Based on the histopathological grade of the tumor, patients were counseled to undergo either RNU (high- grade tumors) or conservative management and follow-up (low-grade tumor). RESULTS RNU was performed in 31 patients, while the remaining 47 patients (undergone Tm:YAG ablation only) were followed up for a mean of 11.7 months with only 19.2% of patients showing upper tract recurrence and no patients showed postoperative ureteral strictures. Limitations include the short follow-up and retrospective nature of the study. CONCLUSIONS On the short term, thulium Laser ablation of UTUC is safe and feasible especially in low-grade UTUC.

Abstract
Upper tract urothelial carcinoma (UTUC) is a common and lethal malignancy. Patients diagnosed with this illness often face invasive workups, morbid therapies, and prolonged post-operative surveillance. UTUC represents approximately 5-10% of urothelial malignancies in the United States and affect 4600-7800 new patients annually. Various environmental exposures as well as smoking have been implicated in the development of UTUC. The diagnosis and workup of UTUC relies on heavily on imaging studies, a close working relationship between Urologists and Radiologists, and invasive procedures such as ureteroscopy. Treatments range from renal-sparing endoscopic surgery to radical extirpative surgery depending on the specific clinical situation. Follow-up is crucial as UTUC has a high recurrence rate. Here we review the epidemiology, diagnosis, management strategies, and follow-up of UTUC from an interdisciplinary perspective.

Abstract
Background The appropriate application of various treatment for upper tract urothelial carcinomas (UTUCs) is the key to prolong the survival of UTUC patients. Herein, we used data in our database to assess the oncological outcomes between partial ureterectomy (PU) and radical nephroureterectomy (RNU). Methods From 2007 to 2014, 255 patients with UTUC undergoing PU or RNU in our hospital database were investigated. Perioperative, postoperative data, and pathologic outcomes were obtained from our database. Cancer-specific survival (CSS) was assessed through the Kaplan-Meier method with Cox regression models to test the effect of these two surgery types. Results The mean length of follow-up was 35.8 months (interquartile range 10–47 months). Patients with high pT stage (pT2–4) suffered shorter survival span (HR: 9.370, 95% CI: 2.956–29.697, P < 0.001). There were no significant differences in CSS between PU and RNU (P = 0.964). In the sub-analysis, CSS for RNU and PU showed no significant difference for pTa–1 or pT2–4 tumor patients (P = 0.516, P = 0.475, respectively). Conclusions PU is not inferior to RNU in oncologic outcomes. Furthermore, PU is generally recognized with less invasive and better renal function preservation compared with RNU. Thus, PU would be rational for specific patients with UTUCs.

Abstract
Purpose To provide an overview of treatment modalities for management of upper tract urothelial carcinoma (UTUC). Methods In accordance with the standards for a scoping review, data presentation and discussion at the Consultation on UTUC in Stockholm, 6–7 September 2018, consensus was reached on the latest and most important treatment recommendations for UTUC. Using Pubmed, Web of Science, and Embase, publications were selected based on quality, clinical relevance, and level of evidence. Results Kidney-sparing surgery should be attempted for low-grade UTUC. Radical nephroureterectomy with bladder cuff excision is first option for high-grade disease. Post-operative bladder instillation of chemotherapy should be offered after RNU to reduce intravesical recurrence rate. Identification of tumor grade and stage is crucial when selecting treatment. Ureteroscopic management of low-grade and non-invasive UTUC achieves disease-free survival similar to that offered by radical nephroureterectomy but seems to be a risk factor for intravesical recurrence. Lymphadenectomy appears important for high-risk disease, although the therapeutic benefit needs further validation. There is little evidence supporting use of Bacillus Calmette–Guérin (BCG) and mitomycin C as monotherapy and adjuvant treatment in UTUC. A randomized clinical trial has indicated that platin-based chemotherapy for invasive UTUC improves disease-free survival, suggesting that adjuvant chemotherapy should be considered standard care for ≥ T2 N0–3M0 disease. Conclusions Risk stratification assessment is feasible and mandatory in UTUC. Identification of tumor grade and stage is essential for optimal treatment selection. Kidney-sparing surgery should be offered in low-risk disease, whereas radical nephroureterectomy and adjuvant chemotherapy should be considered in high-risk disease.

Abstract
OBJECTIVES Limited literature is available on the tumor microenvironment (TM) of upper tract urothelial carcinoma (UTUC). This study comprehensively reviews programmed death 1 receptor (PD-1)-positive and CD8+ tumor-infiltrating lymphocytes (TILs) and programmed death ligand 1 (PD-L1) expression on tumor epithelium (TE). METHODS Seventy-two nephroureterectomy specimens were analyzed for PD-L1, PD-1, and CD8. One percent or more tumor and lymphohistiocyte PD-L1 expression was considered positive. TIL density by H&E was scored semiquantitatively from 0 to 3, and CD8+ and PD-1+ TILs were quantified in hotspots. RESULTS Of the cases, 37.5% demonstrated PD-L1+ on TE. PD-L1+ TE showed an association with pathologic stage (P = .01), squamous differentiation (SqD) (P < .001), TILs by H&E (P = .02), PD-1+ peritumoral TILs (P = .01), and PD-L1+ peritumoral lymphohistiocytes (P = .002). Finally, there was a significant difference in PD-1+ peritumoral TILs in cases with SqD vs no SqD (P = .03). CONCLUSIONS Aggressive UTUC is associated with a distinct TM. Furthermore, TM of UTUC-SqD was distinctly different from those with no SqD, warranting study in a larger cohort.

Abstract
OBJECTIVE We aimed to report our 25-year experience on upper tract urothelial carcinoma (UTUC) on a larger number of patients with long-term follow-up at a single tertiary urology institute. MATERIAL AND METHODS A retrospective study was conducted on 275 patients from 1990 to 2015. Basic patient demographic data with the laboratory and radiologic investigations were collected. We used 1997 TNM classification and the three-tiered WHO grading system. Data were collected using an SPSS® version 21 spreadsheet. RESULTS The mean age was 59±11 years, and 88% of all the patients were male. Previous and concurrent bladder tumors were found in 16% and 26%, respectively. Computed tomography gave an overall accuracy of 96%. Open nephroureterectomy and bladder cuff excision was performed for 85%, and the remaining by laparoscopy and nephron-sparing surgeries. Tumor was pelvicalyceal, ureteric, and both in 40%, 40%, and 20% respectively. In 97% of the patients, the tumor was transitional cell carcinoma. Nearly two-thirds of the patients were of low grade and non-invasive in stage. Nearly half of the patients (46%) had bladder tumor recurrence after NU. Bladder, urethral, and contralateral recurrence, distant, local metastasis occurred in 46%, 2%, 1%, 7.5%, and 6%, respectively. CONCLUSION UTUC is a unique disease with synchronous and metachronous urothelial tumor recurrence that requires long-term surveillance. The majority (two-thirds) of the patients are non-invasive in stage of grade II. Tumor stage is of paramount prognostic significance for survival; the five-year survival rate of T1 and T4 is 80% and 0%, respectively.

Abstract
Laser technology has long been a standard treatment for many diseases. In particular, laser treatment is considered the standard of care in various urological diseases. While originally primarily restricted to stone treatment, lasers have since evolved to play an important role even in the treatment of malignant diseases. In this review, we take a closer look at the history of lasers in urology and some implications for treatments today.

Abstract
Urothelial carcinoma of the upper urinary tract is a rare disease. Tumor biology is comparable to transitional cell carcinomas of the bladder. Local tumor control is much more difficult to achieve in the upper urinary tract than in the bladder. Radical nephroureterectomy is often performed due to carcinomas with low grade histology. Progression rates in these cases are rare; overtreatment has to be discussed. The current article uses the available published data to discuss whether local treatment is an option for tumors of the upper urinary tract. Summarizing the available data, it is indicated that if complete resectability is possible organ preservation is equivalent to radical nephroureterectomy independent of the T‑ and G‑category of the tumor.

Treatment utilization and overall survival in patients receiving radical nephroureterectomy versus endoscopic management for upper tract urothelial carcinoma: evaluation of updated treatment guidelines. World J Urol 2018; 37:1157-1164. [PMID: 30267197 DOI: 10.1007/s00345-018-2506-1] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2018] [Accepted: 09/24/2018] [Indexed: 01/19/2023] Open
Abstract
PURPOSE While radical nephroureterectomy (RNU) is the gold standard treatment for upper tract urothelial carcinoma (UTUC), select patients may benefit from endoscopic treatment (ET). European Association of Urology guidelines recommend ET for patients with low-risk (LR) disease: unifocal, < 2 cm, low-grade lesions without local invasion. To inform the utility of ET, we compare the overall survival (OS) of patients receiving ET and RNU using current and previous guidelines of LR disease. MATERIALS AND METHODS Patients with non-metastatic, cT1 or less UTUC diagnosed in 2004-2012 were collected from the National Cancer Database. OS was analyzed with inverse probability of treatment weighted Cox proportional hazard regression. Analyses were conducted for LR disease under updated (size < 2 cm) and previous guidelines (size < 1 cm). RESULTS Patients who were older, healthier, and treated at an academic facility had higher odds of receiving ET. In 851 identified patients with LR disease, RNU was associated with increased OS compared with ET (p = 0.006); however, there was no difference between ET and RNU (p = 0.79, n = 202) under the previous guidelines (size < 1 cm). In, otherwise, LR patients, the largest tumor size with no difference between ET and RNU was ≤ 1.5 cm (p = 0.07). CONCLUSIONS RNU is associated with improved survival when compared with ET in the management of LR UTUC using current guidelines with a size threshold of < 2 cm. In appropriately selected LR patients, we find no difference between RNU and ET up to a tumor size of ≤ 1.5 cm. However, in the absence of prospective studies, the usage of ET is best left up to clinician discretion.

Abstract
Background To clarify if diagnostic ureteroscopy (URS) before radical nephroureterectomy for patients with upper tract urothelial carcinoma (UTUC) will increase the risk of intravesical recurrence. Methods From retrospective review of cohort at our institution, 502 patients with UTUC who underwent radical nephroureterectomy with bladder cuff excision were enrolled from 1990 to 2013. Cox proportional hazards model was used to analyze the overall survival (OS), disease-free survival (DFS), metastasis-free survival (MFS), and intravesical recurrence-free survival (IVRFS). The log-rank test was used for comparing survival curves. All potential risk factors were included in the multivariate Cox proportional hazards model to recognize independent predictors. From NHI database, we included patients of UTUC without bladder cancer history using population-based database in Taiwan from 1996 to 2013. In total, 3079 URS and 2634 non-URS patients with UTUC were identified. Univariate and multivariate Cox proportional hazards regressions were performed to measure the risk of IVRFS and all-cause mortality. Results From our database, the comparison of clinicopathological characteristics in UTUC patients between with URS biopsy group (URS+) (n = 206, 41%) and without URS biopsy group (URS−) (n = 296, 59%) was insignificantly different excluding surgical method. URS biopsy is not associated with worse OS (p = 0.720), DFS (p = 0.294), MFS (p = 0.808), and IVRFS (p = 0.560) by multivariate analysis. Only bladder cancer history is an independent significant factor to predict IVR (p < 0.001). The same result from NHI database, URS before radical surgery will not increase the risk of IVRFS [adjusted HR 1.136, 95% CI 1.00–1.30; P = 0.059] and OS [adjusted HR 0.919, 95% CI 0.82–1.04; P = 0.164]. Conclusions Preoperative URS manipulation is not associated with higher risk of IVRFS even in patients without bladder cancer history. Diagnostic URS is feasible to compensate the insufficient information of image in patients with UTUC.

Abstract
Upper tract urothelial carcinoma (UTUC) is relatively rare and accounts for approximately 5% of all urothelial carcinomas. The estimated annual incidence of UTUC in Western countries is about two new cases per 100,000 inhabitants. The management of patients with upper tract urothelial carcinomas has changed significantly over the last decade with improved diagnostic techniques and treatment options. The gold-standard treatment used to be open radical nephroureterectomy with removal of the ipsilateral bladder cuff. The use of minimally invasive techniques for the diagnosis and management of upper urinary tract urothelial carcinoma is however expanding and has led to a paradigm shift in treatment strategies of upper tract urothelial carcinomas. In this article, we review the current diagnostic modalities and various endoscopic techniques being currently used in the management of this relatively rare tumour.

Abstract
OBJECTIVE To investigate the outcomes of patients with upper tract urothelial carcinoma (UTUC) with non-definitive therapy, which currently remains unknown. PATIENTS AND METHODS We used the Surveillance, Epidemiology, and End Results (SEER) database to identify individuals with a localised, histologically confirmed kidney/renal pelvis and ureteric UC. Survival analysis using the Kaplan-Meier method was performed. A competing risk model evaluated the cumulative incidence and predictors of cancer-specific mortality (CSM). RESULTS We identified 633 (7.6%) individuals who did not receive surgery. These individuals were significantly older (median age 81 vs 71 years, P < 0.001) than surgically managed patients. The median overall survival (OS) was significantly shorter compared to the surgical cohort (1.9 vs 7.8 years, P < 0.001). The 3-year disease-specific survival (DSS) for patients without surgery was significantly lower compared to those with surgery, at 73.7% vs 92.4%, respectively (P < 0.001). The 3-year DSS for patients with high-grade tumours was worse when compared to patients with low-grade tumours, at 65.1% vs 82.9%, respectively (P < 0.001). The 3-year cumulative CSM was 26.3%. On multivariable analysis, older age (hazard ratio [HR] 1.05, P < 0.001) and high tumour grade (HR 1.88, P < 0.001) were predictors of worse outcomes. CONCLUSIONS In this population-based cohort, 7.6% of patients with UTUC were managed with a non-definitive approach. The median OS for the untreated cohort was significantly shorter compared to the surgical cohort (1.9 vs 7.8 years, respectively). These data may be helpful in counselling patients who are poor surgical candidates, as non-definitive therapy may provide reasonable oncological outcomes.

Abstract
PURPOSE We tested the effects of tumor size, distribution and grade on progression-free survival in patients with upper tract urothelial carcinoma treated with flexible ureteroscopy with Ho:YAG laser photoablation. MATERIALS AND METHODS Included in analysis were data on 92 consecutive patients with upper tract urothelial carcinoma treated with Ho:YAG laser photoablation from 2003 to 2015 at a single tertiary care referral center. Stringent followup was offered according to EAU (European Association of Urology) guidelines. Progression during followup was defined by tumor upgrading, distant metastases and/or a relapsing tumor that could not be completely removed with a conservative approach. Kaplan-Meier curves were used to assess the rate of disease progression according to tumor size (1 or less cm vs greater than 1 cm), tumor distribution (unifocal vs multifocal) and tumor grade (low vs high). Cox regression analysis was done to test the impact of clinical and pathological characteristics on the rate of progression-free survival. RESULTS At a median followup of 52 months (IQR 27.8-76.4) the progression-free survival rate was 68% vs 72% in patients with a tumor size of 1 or less vs greater than 1 cm (p = 0.9), 72% vs 69% in patients with unifocal vs multifocal lesions (p = 0.6) and 75% vs 52% in patients with a low vs a high grade tumor (p = 0.03). On multivariable Cox regression analysis tumor grade at first treatment was the only independent predictor of disease progression (HR 5.16, 95% CI 1.19-22.26, p = 0.03). CONCLUSIONS High tumor grade independently decreased progression-free survival in patients with upper tract urothelial carcinoma treated with Ho:YAG laser photoablation. Tumor size greater than 1 cm and multifocality did not increase the risk of disease progression in patients treated conservatively with Ho:YAG laser photoablation.

Abstract
INTRODUCTION We sought to assess the long-term results of conservative treatment for upper urinary tract carcinoma (UUTC) with regard to tumour recurrence and preservation of renal unit. METHODS From October 1987 to January 2014, 65 patients (median age 68 years) were diagnosed with UUTC and underwent endoscopic and open surgical techniques. Thirteen patients had bilateral disease and one had a single kidney. The primary approach was endoscopic in 37 reno-ureteral units (20 percutaneous resections, 17 ureteroscopies ). Open surgery was performed in 19 cases. A total of 20 patients received mitomycin C. RESULTS Superficial stage pTa or T1 was noted in 37 patients, infiltrating stage pT2 and pT3 in seven and inverted papilloma in one. The stage of the tumour was impossible to classify in 20. With a median followup of 75.12 months (interquartile range [IQR] 144.71-17.41), the kidney preservation, recurrence, specific survival, and global survival rates were 78.5% (51/65), 40.0% (26/65), 92.3% (60/65), and 69.2% (45/65), respectively. From the patients who had recurrence, 15 were salvaged with radical nephroureterectomy (RNU). The bladder tumour recurrence rate after the surgery was 30.76% (20/65). At the end of the followup, five patients had died of UUTC progression and 16 from other causes. Postoperative complications included one case of fistula, one case of stricture, and one case of nephrectomy due to bleeding. CONCLUSIONS In selected cases, conservative management is a safe and feasible alternative to RNU, with the advantage of renal unit preservation.

Abstract
PURPOSE OF REVIEW This study aims to make the reader be aware of recent trends regarding the endoscopic management of upper tract urothelial carcinoma (UTUC) via review of the urologic literature over the past 5 years. Given the rare incidence of this disease, and the lack of level 1 evidence, systematic reviews and meta-analyses were also evaluated. Studies of importance are also considered and outlined in the annotated reference section. RECENT FINDINGS The PubMed database was queried using the following medical subject headings (MeSH terms): "carcinoma, transitional cell," "ureter," "ureteral neoplasms," "kidney pelvis," "endoscopy," "laser therapy," "ureteroscopy," "urologic surgical procedures," and "ureteroscopes." MeSH terms were linked together in varying combinations and limited to human studies in English. Given the relatively rare nature of upper tract urothelial carcinoma (UTUC), level 1 evidence regarding the efficacy of endoscopic treatment does not exist, even after 30+ years of experience. Rather, the literature available mostly is in the form of single institutional retrospective series consisting of relatively small numbers of patients with short to intermediate follow-up. Only within the last 3 years have published series with larger numbers of patients and mean follow-up over 5 years been made available. Even with these more robust experiences, comparisons among series are difficult given variable treatment and follow-up approaches. Most endoscopically managed UTUC will locally recur, especially with longer follow-up. Renal preservation rate is high, however, approaching 80% with follow-up well over 3 years. Patients with high-grade disease often fare poorly regardless of treatment modality. As such, endoscopic management for high-grade urothelial carcinoma should only be used in exceptional circumstances (i.e., in those patients medically unfit for NU or those with solitary kidneys wishing to avoid the morbidity of dialysis). No level 1 evidence exists for the routine use of intraluminal adjuvant therapy for UTUC (i.e., BCG and Mitomycin C) and multiple retrospective observational series claim there is no overt benefit. The recent formation of multiple international groups with interest in UTUC may eventually lead to the production of level 1 studies regarding optimal treatment; however, uniformity in treatment approach will likely still offer challenges.

Abstract
To examine the ability of a new specimen handling technique to improve histopathological yield of ureteroscopic biopsies, performed in patients with suspected upper tract urothelial carcinoma (UTUC). In a bi-center retrospective study we compared the results of the new tissue handling technique (group 1) with the standard technique (group 2). In the new technique, to achieve maximal tissue preservation, the specimen is mounted on filter paper prior to embedding in paraffin. Multivariate analysis was performed to determine which factors are associated with optimal histological results. We further compared the biopsies with the final specimen in a subgroup of patients who underwent nephroureterectomy (NU). Of 55 ureteroscopic biopsies, 1 biopsy from group 1 (new technique) and 3 biopsies from group 2 (standard technique) were inadequate for pathological examination. 51 UTUC specimens were analyzed. Tumor grade and stage were determined in 85% and 63% of the patients in group 1 and in 83% and 25% of group 2 (p=0.85 and p=0.007). Orientation was preserved in 82% of group 1 and 42% of group 2 (p=0.003). On multivariate analysis biopsy technique and biopsy diameter were found to predict stage determination (p=0.01 and p=0.007) and tissue orientation (p=0.005 and p=0.04). Among patients who underwent NU, stage concordance between the biopsy and final pathology was observed in 56% and 27% of the patients in group 1 and 2, respectively. The new processing technique for small UTUC forceps biopsies decreases the rate of biopsies with insufficient material and improves biopsy interpretation.

Abstract
Upper tract urothelial carcinoma (UTUC) is a rare condition and recommendations based on a high level of evidence for diagnosis, treatment and follow-up monitoring are lacking. Current decision-making is often based on evidence from trials investigating urothelial carcinoma of the lower tract. Radical nephroureterectomy has been the standard of care for UTUC but kidney-sparing treatment using endoscopic approaches has been established for a select patient group with low-grade and low-stage disease. Optimal treatment choice requires correct tumour characterization. According to available recommendations, diagnostic work-up of UTUC includes evaluation by CT urography or MRI urography, cystoscopy and urine cytology. Ureterorenoscopy and lesion biopsy are grade C recommendations in patients with suspected UTUC. When kidney-sparing treatment is planned, ureterorenoscopy and biopsy should be considered and are the procedures of choice in most cases. These diagnostics have limitations and their accuracy varies in defining tumour characteristics and predicting grade and stage. Urinary tests have higher sensitivity than cytology for detection of lower tract urothelial carcinoma but evidence of their benefit in UTUCs is lacking. New optical and image enhancement techniques are being developed to facilitate real-time diagnostics with increased accuracy. A new diagnostic algorithm for patients with suspected UTUC that integrates the diagnosis, treatment and clinical risk stratification is required.

Abstract
CONTEXT There is uncertainty regarding the oncologic effectiveness of kidney-sparing surgery (KSS) compared with radical nephroureterectomy (RNU) for upper tract urothelial carcinoma (UTUC). OBJECTIVE To systematically review the current literature comparing oncologic outcomes of KSS versus RNU for UTUC. EVIDENCE ACQUISITION A computerised bibliographic search of the Medline, Embase, and Cochrane databases was performed for all studies reporting comparative oncologic outcomes of KSS versus RNU. Approaches considered for KSS were segmental ureterectomy (SU) and ureteroscopic (URS) or percutaneous (PC) management. Using the methodology recommended by the Preferred Reporting Items for Systematic Reviews and Meta-analysis guidelines, we identified 22 nonrandomised comparative retrospective studies published between 1999 and 2015 that were eligible for inclusion in this systematic review. A narrative review and risk-of-bias (RoB) assessment were performed using cancer-specific survival (CSS) as the primary end point. EVIDENCE SYNTHESIS Seven studies compared KSS overall (n=547) versus RNU (n=1376). Information on the comparison of SU (n=586) versus RNU (n=3692), URS (n=162) versus RNU (n=367), and PC (n=66) versus RNU (n=114) was available in 10, 5, and 2 studies, respectively. No significant difference was found between SU and RNU in terms of CSS or any other oncologic outcomes. Only patients with low-grade and noninvasive tumours experienced similar CSS after URS or PC when compared with RNU, despite an increased risk of local recurrence following endoscopic management of UTUC. The RoB assessment revealed, however, that the analyses were subject to a selection bias favouring KSS. CONCLUSIONS Our systematic review suggests similar survival after KSS versus RNU only for low-grade and noninvasive UTUC when using URS or PC. However, selected patients with high-grade and invasive UTUC could safely benefit from SU when feasible. These results should be interpreted with caution due to the risk of selection bias. PATIENT SUMMARY We reviewed the studies that compared kidney-sparing surgery versus radical nephroureterectomy for upper tract urothelial carcinoma. We found similar oncologic outcomes for favourable tumours when using ureteroscopic or percutaneous management, whereas indications for segmental ureterectomy could be extended to selected cases of aggressive tumours.

Survival Comparison Between Endoscopic and Surgical Management for Patients With Upper Tract Urothelial Cancer: A Matched Propensity Score Analysis Using Surveillance, Epidemiology and End Results-Medicare Data. Urology 2016; 95:115-20. [PMID: 27233931 DOI: 10.1016/j.urology.2016.05.033] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2016] [Revised: 05/04/2016] [Accepted: 05/17/2016] [Indexed: 12/11/2022]
Abstract
OBJECTIVE To determine survival differences among patients receiving endoscopic vs surgical management for upper tract urothelial carcinoma (UTUC). MATERIALS AND METHODS Using Surveillance, Epidemiology and End Results-Medicare data, patients diagnosed with nonmuscle-invasive, low-grade UTUC as their first cancer diagnosis between 2004 and 2009 were identified. Receipts of endoscopic and surgical interventions were assessed, and patients were separated into surgical or endoscopic management cohorts. Two-to-one propensity score analysis was performed to control for baseline characteristics between groups. RESULTS The endoscopic management (n = 151) and matched surgical management (n = 302) groups demonstrated no significant differences in age, gender, race, marital status, Charlson comorbidity index, or year of diagnosis. Endoscopic management was an independent and significant predictor of all-cause and cancer-specific mortality (hazard ratio 1.6 for overall survival [OS], hazard ratio 2.1 for cancer-specific survival [CSS]). Kaplan-Meier estimated survival was significantly lower for endoscopic management, with both OS and CSS curves diverging at approximately 24-36 months. A subset of patients initially receiving endoscopic management went on to receive surgical intervention (80/151 = 53%) at a median of 8.8 months from diagnosis. For these patients, Kaplan-Meier-estimated CSS was not significantly different from those who continued with only endoscopic management, and remained significantly lower than patients who received upfront surgery. CONCLUSION Although initial survival outcomes (first 24 months) are similar for endoscopic and surgical management of nonmuscle-invasive, low-grade UTUC, both CSS and OS are significantly inferior for the endoscopic management group in the longer term. Furthermore, transition from initial endoscopic management to surgical intervention appears to have limited impact on survival.

Abstract
Purpose Upper tract urothelial carcinoma (UTUC) is a rare and poorly investigated disease. Intense collaborative efforts have increased our knowledge and improved the management of the disease. The objective of this review was to discuss recent advances and unmet needs in UTUC. Methods A non-systematic Medline/PubMed literature search was performed on UTUC using the terms “upper tract urothelial carcinoma” with different combinations of keywords. Original articles, reviews and editorials in English language were selected based on their clinical relevance. Results UTUC is a disease with specific epidemiologic and risk factors different to urothelial carcinoma of the bladder (UCB). Similarly to UCB, smoking increases the risk of UTUC and worsens its prognosis, whereas aristolochic acid (AA) exposure and mismatch repair genes abnormality are UTUC specific risk factors. A growing understanding of biological pathways involved in the tumorigenesis of UTUC has led to the identification of promising prognostic/predictive biomarkers. Risk stratification of UTUC is difficult due to limitations in staging and grading. Modern imaging and endoscopy have improved clinical decision-making, and allowed kidney-sparing management and surveillance in favorable-risk tumors. In high-risk tumors, radical nephroureterectomy (RNU) remains the standard. Complete removal of the intramural ureter is necessary with inferiority of endoscopic management. Post-RNU intravesical instillation has been shown to decrease bladder cancer recurrence rates. While the role of neoadjuvant cisplatin based combination chemotherapy and lymphadenectomy are not clearly established, the body of evidence suggests a survival benefit to these. There is currently no evidence for adjuvant chemotherapy (AC) in UTUC. Conclusions Despite growing interest and understanding of UTUC, its management remains challenging, requiring further high quality multicenter collaborations. Accurate risk estimation is necessary to avoid unnecessary RNUs while advances in technology are still required for optimal kidney-sparing approaches.

Abstract
OBJECTIVE To develop an evidence-based approach to the diagnostic workup of suspicious upper urinary tract lesions. METHODS The PubMed database was searched using the following terms with a filter for English language: "upper tract urothelial carcinoma" and "upper tract transitional cell carcinoma," along with the following corresponding terms: "cost," "epidemiology," "diagnosis," "ureteroscopy," and "workup." A total of 404 articles were returned, and 33 were reviewed in full based on relevance. RESULTS Computed tomography urogram is both sensitive and specific (96% and 99%). Cytology is utilized for its specificity (89%-100%). Ureteroscopy and biopsy of an upper tract lesion can be helpful in equivocal cases but can pose challenges in terms of yield and eventual pathologic upstaging. Due to the high sensitivity and specificity of other noninvasive tests, ureteroscopy can be obviated in select cases. We assess the available evidence and devise an algorithm for the evaluation of an upper tract urothelial carcinoma lesion. CONCLUSION Ureteroscopy can be omitted as part of the diagnostic workup in appropriately selected cases of upper tract urothelial carcinoma.

Abstract
PURPOSE Tissue diagnosis of upper tract urothelial carcinoma (UTUC) is limited by variance in tumor sampling by standard ureteroscopic biopsy. Optical imaging technologies can potentially improve UTUC diagnosis, surveillance, and endoscopic treatment. We previously demonstrated in vivo optical biopsy of urothelial carcinoma of the bladder using confocal laser endomicroscopy (CLE). In this study, we evaluated a new 0.85-mm imaging probe in the upper urinary tract and demonstrated feasibility and compatibility with standard ureteroscopes to achieve in vivo optical biopsy of UTUC. MATERIALS AND METHODS Fourteen patients scheduled for ureteroscopy of suspected upper tract lesions or surveillance of UTUC were recruited. After intravenous (IV) administration of fluorescein, CLE was performed using a 0.85-mm-diameter imaging probe inserted through the working channel of standard ureteroscopes. Acquired confocal video sequences were reviewed and analyzed. A mosaicing algorithm was used to compile a series of images into a single larger composite image. Processed CLE images were compared with standard histopathologic analysis. RESULTS Optical biopsy of the UTUC using CLE was effectively achieved during standard ureteroscopy. There were no adverse events related to IV fluorescein administration or image acquisition. Confocal imaging of UTUC showed characteristic features similar to urothelial carcinoma of the bladder, including papillary structure, fibrovascular stalks, and pleomorphism. Lamina propria in normal areas of the renal pelvis and ureter was also identified. CONCLUSIONS We report an initial feasibility of CLE of UTUC. Pending further clinical investigation, CLE may become a useful adjunct to ureteroscopic biopsy, endoscopic ablation, and surveillance of UTUC.
