Abstract
PURPOSE The diagnostic accuracy of computed tomography urography for upper tract urothelial carcinoma is high; however, difficulties are associated with precisely assessing the T stage. Preoperative tumor staging has an impact on treatment options for upper tract urothelial carcinoma. We herein attempted to identify preoperative factors that predict pathological tumor up-staging, which will facilitate the selection of treatment strategies. MATERIALS AND METHODS We retrospectively identified 148 patients with upper tract urothelial carcinoma who underwent computed tomography urography preoperatively followed by radical nephroureterectomy without preoperative chemotherapy at our institution between 2000 and 2021. Preoperative factors associated with cT2 or lower to pT3 up-staging were examined using a multivariate logistic regression analysis. RESULTS Ninety out of 148 patients were diagnosed with cT2 or lower, and 22 (24%) were up-staged to pT3. A multivariate analysis identified a positive voided urine cytology (HR 4.69, p = 0.023) and tumor length ≥ 3 cm (HR 6.33, p = 0.003) as independent predictors of pathological tumor up-staging. CONCLUSIONS Patients diagnosed with cT2 or lower, but with preoperative positive voided urine cytology and/or tumor diameter ≥ 3 cm need to be considered for treatment as cT3.

Abstract
PURPOSE To investigate computed tomography (CT)-based prediction model for identifying patients with high probability of non-muscle-invasive bladder cancer (NMIBC). METHODS This retrospective study evaluated 147 consecutive patients who underwent contrast-enhanced CT and surgery for bladder cancer. Using corticomedullary-to-portal venous phase images, two independent readers analyzed bladder muscle invasion, tumor stalk, and tumor size, respectively. Three-point scale (i.e., from 0 to 2) was applied for assessing the suspicion degree of muscle invasion or tumor stalk. A multivariate prediction model using the CT parameters for achieving high positive predictive value (PPV) for NMIBC was investigated. The PPVs from raw data or 1000 bootstrap resampling and inter-reader agreement using Gwet's AC1 were analyzed, respectively. RESULTS Proportion of patients with NMIBC was 81.0% (119/147). The CT criteria of the prediction model were as follows: (a) muscle invasion score < 2; (b) tumor stalk score > 0; and (c) tumor size < 3 cm. From the raw data, PPV of the model for NMIBC was 92.7% (51/55; 95% confidence interval [CI] 82.4-98.0) in reader 1 and 93.3% (42/45; 95% CI 81.7-98.6) in reader 2. From the bootstrap data, PPV was 92.8% (95% CI 85.2-98.3) in reader 1 and 93.4% (95% CI 84.9-99.9) in reader 2. The model's AC1 was 0.753 (95% CI 0.647-0.859). CONCLUSION The current CT-derived prediction model demonstrated high PPV for identifying patients with NMIBC. Depending on CT findings, approximately 30% of patients with bladder cancer may have a low need for additional MRI for interpreting vesical imaging-reporting and data system.

Abstract
Purpose This study aimed to evaluate the oncological outcome of delayed surgical wait time from the diagnosis of upper tract urothelial carcinoma (UTUC) to radical nephroureterectomy (RNU). Methods In this multicenter retrospective study, medical records were collected between 1988 and 2021 from 18 participating Taiwanese hospitals under the Taiwan UTUC Collaboration Group. Patients were dichotomized into the early (≤90 days) and late (>90 days) surgical wait-time groups. Overall survival, disease-free survival, and bladder recurrence-free survival were calculated using the Kaplan-Meier method and multivariate Cox regression analysis. Multivariate analysis was performed using stepwise linear regression. Results Of the 1251 patients, 1181 (94.4%) were classifed into the early surgical wait-time group and 70 (5.6%) into the late surgical wait-time group. The median surgical wait time was 21 days, and the median follow-up was 59.5 months. Our study showed delay-time more than 90 days appeared to be associated with worse overall survival (hazard ratio [HR] 1.974, 95% confidence interval [CI] 1.166-3.343, p = 0.011), and disease-free survival (HR 1.997, 95% CI 1.137-3.507, p = 0.016). This remained as an independent prognostic factor after other confounding factors were adjusted. Age, ECOG performance status, Charlson Comorbidity Index (CCI), surgical margin, tumor location and adjuvant systemic therapy were independent prognostic factors for overall survival. Tumor location and adjuvant systemic therapy were also independent prognostic factors for disease-free survival. Conclusions For patients with UTUC undergoing RNU, the surgical wait time should be minimized to less than 90 days. Prolonged delay times may be associated with poor overall and disease-free survival.

Abstract
INTRODUCTION The aim was to propose an update of the French Urology Association Cancer Committee (ccAFU) Recommendations on the management of upper urinary tract urothelial carcinomas (UUT-UC). METHODS A systematic Medline search was performed between 2020 and 2022, taking account of the diagnosis, treatment options and follow-up of UUT-UC, while evaluating the references with their levels of evidence. RESULTS The diagnosis of this rare pathology is based on CTU acquisition during excretion and flexible ureterorenoscopy with histological biopsies. Radical nephroureterectomy (RNU) remains the gold standard for surgical treatment. Nevertheless conservative treatment can be discussed for low risk lesions: tumour of low-grade, with no infiltration on imaging, unifocal<2cm, eligible for full treatment therefore requiring close endoscopic surveillance by flexible ureteroscopy in compliant patients. After RNU, postoperative instillation of chemotherapy is recommended to reduce the risk of recurrence in the bladder. Adjuvant chemotherapy has shown clinical benefits compared to surveillance after RNU for tumours (pT2-T4 N0-3 M0). CONCLUSION These updated recommendations should contribute to improving not only patients' level of care, but also the diagnosis and decision-making concerning treatment for UUT-UC.

Abstract
Urothelial tumours are the fourth most common cancer in the world and account for the majority of tumours involving the bladder. The symptom that often leads to diagnosis is the presence of haematuria. Diagnosis is made by cystoscopy, which is currently the gold standard in bladder cancer. Computed tomography (CT) performed with pre- and post-contrastographic phases is essential in order to assess the loco-regional and distant extension of disease. The diagnosis and staging of upper tract urothelial cancer (UTUC) are best done with computed tomography urography and flexible ureteroscopy (URS). In the acquisition protocol of this type of tumour, a urographic phase is mandatory, which allows for an accurate diagnostic assessment of the renal pelvis, ureter and bladder, especially in papillary forms. The use of multiple acquisition phases, especially in this type of patient who will have to perform follow-up CTs, leads to the problem of overexposure to ionising radiation, as well as the frequent administration of iodinated contrast medium. For this reason, in recent year, the focus has been put on advanced technologies such as dual-energy CT (DECT), that is a method that can offer some advantages for both radiologist and patient, in the diagnosis of cancer and, in particular, urinary tract disease.

Abstract
INTRODUCTION This study aimed to evaluate the concordance in tumor stage and grade between ureteroscopic (URS) biopsy and radical nephroureterectomy (RNU) in patients with upper tract urothelial carcinoma (UTUC). PATIENTS AND METHODS Records of 1,214 UTUC patients who had undergone URS biopsy followed by RNU were included. Univariable and multivariable logistic regression analyses were performed to identify factors contributing to the pathological upstaging. RESULTS The concordance between URS biopsy-based clinical and RNU pathological staging was 34.5%. Clinical understaging occurred in 59.5% patients. Upstaging to muscle-invasive disease occurred in 240 (41.7%) of 575 patients diagnosed with ≤cT1 disease. Of those diagnosed with muscle-invasive disease on final pathology, 89.6% had been clinically diagnosed with ≤cT1 disease. In the univariable analyses, computed tomography urography (CTU)-based invasion, ureter location, hydronephrosis, high-grade cytology, high-grade biopsy, sessile architecture, age, and women sex were significantly associated with pathological upstaging (P < .05). In the multivariable analyses, CTU-based invasion and hydronephrosis remained associated with pathological upstaging (P < .05). URS biopsy-based clinical and pathological gradings were concordant in 634 (54.2%) patients. Clinical undergrading occurred in 496 (42.4%) patients. CONCLUSIONS Clinical understaging/undergrading and upstaging to muscle-invasive disease occurred in a high proportion of UTUC patients undergoing RNU. Despite the inherent selection bias, these data underline the challenges of accurate UTUC staging and grading. In daily clinical practice, URS biopsy and CTU offer the most accurate preoperative information albeit with limited predictive value when used alone. These findings should be considered when utilizing preoperative, risk-adapted strategies.

How to manage patients with suspected upper tract urothelial carcinoma in the pandemic of COVID-19? Urol Oncol 2021; 39:733.e11-733.e16. [PMID: 34332847 PMCID: PMC8318925 DOI: 10.1016/j.urolonc.2021.06.007] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2020] [Revised: 01/14/2021] [Accepted: 06/10/2021] [Indexed: 11/21/2022]
Abstract
BACKGROUND The pandemic of COVID-19 has disrupted the clinical pathway for patients with suspected upper tract urothelial carcinoma (UTUC). This aims to investigate the optimal management of UTUC during the pandemic by determining 1) Whether a three-month delay of RNU leads to worsened overall survival, 2) Whether radical nephroureterectomy (RNU) can be performed without prior diagnostic ureteroscopy (URS). METHODS Consecutive patients with RNU performed for suspected UTUC in four hospitals in Hong Kong and Taiwan were included. Patients with histologically proven UTUC and with RNU performed within one year were dichotomized into early (≤3 months) and delayed (>3 months) RNU groups. Diagnostic performances of predictive models based on pre-URS factors (gross haematuria, suspicious or malignant urine cytology, and filling defect or contrast-enhancing mass on computed tomography), with or without URS, were analysed using receiver operating characteristics and area under curve (AUC). Overall survival was analysed using Kaplan-Meier method and multivariate Cox regression analysis. RESULTS Between 2000 and 2019, 665 patients underwent RNU, and 491 of them had prior diagnostic URS. The early RNU group had a better overall survival (P = 0.015). Early RNU was associated with a better overall survival upon multivariate analysis (HR 1.55, 95% CI 1.03-2.33, P = 0.035). Large tumour size, multi-focal tumour, T2 or above disease, and positive nodal status were associated with a poorer overall survival. A combination of any 2 out of the 3 pre-URS factors achieved a positive predictive value of 99.5 to 100%. Presence of all 3 pre-URS factors achieved an AUC of 0.851 with URS, and AUC of 0.809 without URS. CONCLUSIONS A delay of RNU for over 3 months was associated with poorer overall survival and has to be avoided despite the current COVID-19. We can also consider direct RNU based on clinical factors alone. This also avoids URS hospitalization and expedites the clinical pathway of UTUC.

Abstract
This case-based discussion describes the management of a 66-yr-old man who presented to the emergency department with gross hematuria. His urine cytology was benign, and computed tomography (CT) with nephrographic phase revealed a 2.5 cm filling defect within the left renal pelvis and luminal narrowing in the right proximal ureter with hydronephrosis. CT showed no lymphadenopathy and no sign of metastatic disease. Cystoscopy was normal. In a progressive case-based discussion fashion, we will discuss the diagnostic and treatment options with two different perspectives: (1) guidelines-based current standard of care and (2) an outlook on future perspectives using the latest scientific advances that may soon become the standard of care. PATIENT SUMMARY: This presentation of a real-life clinical scenario will be useful in describing the current standard of care and future perspectives regarding the diagnosis and treatment of upper urinary tract tumors.

Abstract
OBJECTIVE The aim of this study was to investigate whether diagnostic ureteroscopy (URS) biopsy is unfavourable for bladder tumour recurrence in upper urinary tract urothelial carcinoma (UTUC). MATERIALS AND METHODS We performed a retrospective analysis of 195 patients diagnosed with UTUC, who were divided into a diagnostic URS group (URS+) and a nondiagnostic URS group (URS-) according to whether diagnostic ureteroscopic biopsy was performed. A Cox regression model was used to analyse the risk factors for intravesical recurrence (IVR)-free survival (IRFS) and overall survival (OS) in UTUC after radical nephroureterectomy (RNU). Kaplan-Meier analysis was used to estimate the influence of factors on the incidence of IVR and the cumulative survival rate of UTUC. RESULTS Patients with a maximum tumour diameter of less than 3.1 cm, low-stage tumours, and ureteral tumours were more likely to undergo diagnostic URS before radical surgery. Multivariate Cox regression analysis showed that tumour pathological stage and diagnostic ureteroscopic biopsy can be used as predictors of IVR after RNU (p = 0.019, 0.033). Kaplan-Meier survival analysis found that diagnostic ureteroscopic biopsy was a high-risk factor for IRFS (p = 0.034). Subcomponent analysis showed that pTa/Tis/T1, pT2, pT3/pT4 stage, and diagnostic ureteroscopic biopsy with pTa/Tis/T1 stage were unfavourable for IVR (p = 0.047). CONCLUSION Diagnostic ureteroscopic biopsy before RNU should be carefully selected for patients with atypical preoperative UTUC. We believe that intravesical chemotherapy drug perfusion can be used after surgery to prevent IVR if biopsy is unavoidable, but this still requires further prospective studies.

Abstract
BACKGROUND Upper tract urothelial carcinoma (UTUC) is a rare urological cancer that is still an important public health concern in many areas around the world. Although UTUC has been linked to a number of risk factors, to our knowledge no systematic review has been published on the overall incidence and prevalence of de-novo UTUC. This review aimed to examine the global epidemiology of UTUC to provide clinicians and public health specialists a better understanding of UTUC. METHODS A systematic search was conducted on MEDLINE, Embase, and the Web of Science using a detailed search strategy. Observational epidemiological studies describing the incidence and prevalence of de-novo UTUC in adults were included, and the Joanna Briggs Institute checklist was used for critical appraisal and data extraction of the studies selected. RESULTS The systematic search identified 3506 papers, of which 59 papers were included for qualitative synthesis. The studies selected included data ranging from the years 1943 to 2018. A comprehensive qualitative synthesis of the data was performed. UTUC incidence generally varied according to age (higher with increasing age), sex (unclear), race (unclear), calendar time (increased, stable, or decreased according to region), geographical region (higher in Asian countries), occupation (higher in seamen and printers), and other population characteristics. Prevalence was only reported by one study, which showed UTUC to have the highest incidence of the rare urogenital cancers in Europe. CONCLUSION This systematic review highlights an increased incidence of UTUC in certain groups, including increasing age and certain occupations such as seamen. The incidence of UTUC also varies between certain geographical regions. The trend of UTUC incidence for sex, race, and calendar time is less clear due to a wide variety of metrics used by the studies identified. More studies are also required on the prevalence of UTUC to understand its disease burden. Trial registration This review was registered on PROSPERO (registration number CRD42019134255).

Tumor heterogeneity evaluated by computed tomography detects muscle-invasive upper tract urothelial carcinoma that is associated with inflammatory tumor microenvironment. Sci Rep 2021; 11:14251. [PMID: 34244567 PMCID: PMC8271017 DOI: 10.1038/s41598-021-93414-2] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2021] [Accepted: 06/22/2021] [Indexed: 12/29/2022] Open
Abstract
To detect muscle-invasive upper tract urothelial carcinoma, we evaluated the internal texture of the tumor using texture analysis of computed tomography images in 86 cases of upper tract urothelial carcinoma. The internal texture of the tumor was evaluated as the value of computed tomography attenuation number of the unenhanced image, and the median, standard deviation, skewness and kurtosis were calculated. Each parameter was compared with clinicopathological factors, and their associations with postoperative prognosis were investigated. Immunohistochemistry was performed to investigate the histological and molecular mechanisms of the inflammatory tumor microenvironment. The histogram of computed tomography attenuation number in non-muscle invasive tumor was single-peaked, whereas muscle invasive tumor showed a multi-peaked shape. In the parameters obtained by texture analysis, standard deviation was significantly associated with pathological stage (p < 0.0001), tumor grade (p = 0.0053), lymphovascular invasion (p = 0.0078) and concomitant carcinoma in situ (p = 0.0177) along with recurrence-free (p = 0.0191) and overall survival (p = 0.0184). The standard deviation value correlated with the amount of stromal components (p < 0.0001) and number of tumor-infiltrating macrophages (p < 0.0001). In addition, higher expression of high mobility group box 1 was found in heterogeneous tumor. Tumor heterogeneity evaluated by texture analysis was associated with muscle-invasive upper tract urothelial carcinoma and represented an inflammatory tumor microenvironment and useful as the clinical assessment to differentiate muscle invasive tumor.

Abstract
INTRODUCTION -The purpose was to propose an update of the French guidelines from the national committee ccAFU on upper tract urothelial carcinomas (UTUC). METHODS - A systematic Medline search was performed between 2018 and 2020, as regards diagnosis, options of treatment and follow-up of UTUC, to evaluate different references with levels of evidence. RESULTS - The diagnosis of this rare pathology is based on CT-scan acquisition during excretion and ureteroscopy with histological biopsies. Radical nephroureterectomy (RNU) remains the gold standard for surgical treatment, nevertheless a conservative endoscopic approach can be proposed for low risk lesion: unifocal tumor, possible complete resection and low grade and absence of invasion on CT-scan. Close monitoring with endoscopic follow-up (flexible ureteroscopy) in compliant patients is therefore necessary. After RNU, bladder instillation of chemotherapy is recommended to reduce risk of bladder recurrence. A systemic chemotherapy is recommended after RNU in pT2-T4 N0-3 M0 disease. CONCLUSION - These updated guidelines will contribute to increase the level of urological care for diagnosis and treatment for UTUC.

Abstract
Purpose To investigate the effect of diagnostic ureteroscopy (URS) on the delay to surgical treatment of upper tract urothelial carcinoma (UTUC) detected by imaging and the risk of intravesical recurrence. Materials and methods We undertook a retrospective case-note analysis of all patients who underwent radical nephroureterectomy (NUU) from November 2012 to July 2019. We identified those who underwent diagnostic ureteroscopy prior to NUU as Group 1 and those who did not undergo diagnostic URS as Group 2. Perioperative and pathological parameters were compared between both groups. Kaplan-Meier and Log-Rank analyses were used to compare delay to NUU and the intravesical recurrence (IVR) free survival. Cox regression models were employed to analyze the risk factors of intravesical recurrence. Results Out of 69 patients with a mean age of 71.3 years and a mean follow-up of 48.5 months, 49 (71%) underwent URS while 20 (29%) did not. The mean time between the computerized tomography urography (CTU) and surgery was 86 days with URS and 59 days in the control groups(p=0.007). Intravesical recurrence in year one postoperatively was 28.2 % in the URS group vs 5.9% in the control group (p=0.04). The Kaplan-Meier curve showed improved, yet insignificant, IVR-free survival for the control group (Log-Rank p-value=0.21). In multivariate Cox regression analysis, concomitant bladder carcinoma was an independent risk factor for IVR (HR, 15.01; 95%CI, 3.311 - 68.07; p=0.0004). Intravesical mitomycin-c was a protective factor (HR 0.154; 95%CI 0.025 - 0.922; p=0.040). Conclusion In our retrospective single-unit study, diagnostic ureteroscopy for CTU-detected upper tract urothelial carcinoma delayed definitive surgical treatment. Furthermore, it was associated with a significantly increased risk of early intravesical recurrence. URS can provide useful information and reassurance prior to major surgery but must be used with caution in light of these findings.

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
PURPOSE Multidetector computed tomographic urography (MDCTU) is not yet sufficient to be used in the clinical staging of upper tract urothelial carcinoma (UTUC). This study aimed to compare the diagnostic accuracy of MDCTU T stage classification and pathologic T staging for UTUC. METHODS We retrospectively evaluated 125 patients with UTUC who underwent preoperative MDCTU. A single radiologist classified the MDCTU pattern of the tumors as either low or advanced T stage for localized or locally advanced tumors, respectively. The diagnostic values of MDCTU for locally advanced tumors and the kappa agreement between MDCTU and pathologic T stage were investigated. RESULTS Among 85 pathologic low T stage (Ta-T2) tumors, 71 low T stage tumors were correctly detected by MDCTU, while 30 out of 40 advanced T stage (T3-T4) tumors were correctly diagnosed by MDCTU. MDCTU led to under-staging in 8% (10/125) tumors and over-staging in 11.2% (14/125) tumors. Therefore, the overall accuracy of MDCTU in the diagnosis of low and advanced T stage tumors was 80.8% (101/125 patients). The sensitivity for advanced T stage tumors was 75% (30/40), the specificity was 83.5% (71/85), and the positive and negative predictive values were 68.1% (30/44) and 87.6% (71/81), respectively. The kappa agreement value between the MDCTU T stage and pathologic T stage was 0.57 (95% confidence interval (CI) 0.42-0.72), which was statistically significant (P = 0.001). CONCLUSION MDCTU T stage classification may be relatively accurate for the detection and staging of UTUC correspondence with a pathologic stage.

[PMID: 32738463 DOI: 10.1016/j.ejrad.2020.109198] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2020] [Revised: 07/12/2020] [Accepted: 07/16/2020] [Indexed: 11/16/2022]
Abstract
OBJECTIVE To determine predictive factors for periureteral fat invasion of ureteral cancer on computed tomography (CT) urography. MATERIALS AND METHODS Consecutive 77 patients with CT urography and surgically proven ureteral cancer were retrospectively evaluated. Three independent radiologists with different experiences in interpreting CT urography analyzed radiologic findings as follows: (a) periureteral infiltration (absent; equivocal; or present); (b) ureteral obstruction (complete obstruction or not); (c) lesion length; (d) lesion width; (e) hydronephrosis grade; and (f) renal atrophy (present or not). We analyzed univariate and multivariate logistic regression. We assessed sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of significant parameters. RESULTS Periureteral fat invasion was surgically identified in 33.8 % (26/77). For reader 1, periureteral infiltration (odds ratio [OR] = 3.330), complete ureteral obstruction (OR = 18.965), and renal atrophy (OR = 3.116) were significant in univariate analysis (p < 0.05), while only complete ureteral obstruction was significant in multivariate analysis (OR = 12.779; p = 0.018). For reader 2 (OR = 4.172; p = 0.019) and 3 (OR = 9.459; p = 0.035), only complete ureteral obstruction was significant in univariate analysis. Sensitivity, specificity, PPV, and NPV of complete ureteral obstruction were 96.2 % (25/26), 43.1 % (22/51), 46.3 % (25/54), and 95.7 % (22/23) for reader 1, 84.6 % (22/26), 43.1 % (22/51), 43.1 % (22/51), and 84.6 % (22/26) for reader 2, and 96.2 % (25/26), 27.5 % (14/51), 40.3 % (25/62), and 93.3 % (14/15) for reader 3, respectively. CONCLUSION Complete ureteral obstruction on CT urography is highly sensitive for extra-ureteral extension of ureteral cancer. Ureteral cancer without complete ureteral obstruction may be less likely to invade periureteral fat.

Diagnostic accuracy of ureteroscopic biopsy in predicting stage and grade at final pathology in upper tract urothelial carcinoma: Systematic review and meta-analysis. Eur J Surg Oncol 2020; 46:1989-1997. [PMID: 32674841 DOI: 10.1016/j.ejso.2020.06.024] [Citation(s) in RCA: 32] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2020] [Revised: 05/21/2020] [Accepted: 06/14/2020] [Indexed: 01/05/2023] Open
Abstract
OBJECTIVE To assess the accuracy of ureteroscopic (URS) biopsies in predicting stage and grade at final pathology in upper tract urothelial carcinoma (UTUC). MATERIALS AND METHODS The meta-analysis was performed in accordance with the PRISMA statement. Studies providing data on tumor stage and grade at URS biopsy and surgical specimens were included. The negative predictive value (NPV) implies concordance between the absence of subepithelial connective tissue invasion or the presence of low-grade tumors at URS biopsy and the absence of a muscle-invasive disease in the final pathology. RESULTS A total of 23 studies were included (3547 patients). The stage-to-stage match between URS biopsy/final pathology showed a positive predictive value (PPV) for cT1+/muscle-invasive disease of 94% (95% CI: 84%-100%) and a NPV for cTa-Tis/non-muscle-invasive disease of 60% (95% CI: 52%-68%). The grade-to-grade match between URS biopsy/final pathology was 66% (95% CI: 55%-77%) for low-grade (cLG/pLG) tumors and 97% (95% CI: 94%-98%) for high-grade (cHG/pHG) tumors. The PPV for cHG/muscle-invasive disease was 60% (95% CI: 54%-66%) and the NPV for cLG/non-muscle-invasive disease was 77% (95% CI: 73%-82%). The undergrading and understaging rates were 32% (95%CI: 25%-38%) and 46% (95% CI: 38%-54%), respectively. CONCLUSIONS There is a substantial correlation between tumor grade at URS biopsy and the final pathology. The identification of cHG tumors and subepithelial connective tissue invasion (cT1+) in URS biopsy showed a moderate and a strong correlation with invasive UTUC, respectively. Nevertheless, a certain risk of undergrading and understaging should be assumed.

Abstract
Objective To develop and validate a preoperative nomogram to predict pathological locally advanced disease (pLAD) of clinically localized upper urinary tract urothelial carcinoma (UTUC) treated with extirpative surgery. Methods In total, 1101 patients with cN0M0 UTUC (development cohort, n = 604; validation cohort, n = 497) from 2 independent academic databases were retrospectively analyzed. pLAD was defined as pT3/4 and/or pN+. Multivariate logistic regression was used to develop a nomogram. The accuracy of the nomogram was evaluated with a receiver operating characteristic curve, calibration plot, and decision curve analysis. Results The development and validation cohorts comprised 204 (33.8%) and 178 (35.8%) patients with pLAD, respectively. The multivariate analyses showed that the neutrophil‐to‐lymphocyte ratio (hazard ratio [HR], 2.27; P < .001), chronic kidney disease (HR, 1.56; P = .032), tumor location (HR, 1.60; P = .029), hydronephrosis (HR, 2.71; P < .001), and local invasion on imaging (HR, 8.59; P < .001) were independent predictive factors. After bootstrapping, a well‐calibrated nomogram achieved discriminative accuracy of 0.77 in the development cohort. The decision curve analysis demonstrated improved risk prediction against threshold probabilities (≥8%) of pLAD. These results were consistent in the validation cohort. Conclusion Our novel nomogram allows for more highly accurate prediction of pLAD of UTUC. This nomogram integrates standard imaging and laboratory factors that help to identify patients who will benefit from preoperative chemotherapy, extended lymph node dissection, or both.

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
Magnetic resonance imaging of the upper tract (pyelocalyces and ureters) or MR Urography (MRU) is technically possible and when performed correctly offers similar visualization of the upper tracts and for detection of non-calculous diseases of the collecting system similar specificity but with lower sensitivity compared to CTU. MRU provides the ability to simultaneously image the kidneys and urinary bladder with improved soft tissue resolution, better tissue characterization and when combined with assessment of the upper tract, a comprehensive examination of the urinary system. MRU requires meticulous attention to technical details and is a longer more demanding examination compared to CTU. Advances in MR imaging techniques including: parallel imaging, free-breathing motion compensation techniques and compressed sensing can dramatically shorten examination times and improve image quality and patient tolerance for the exam. This review article discusses updates in the MRU technique, summarizes clinical indications and opportunities for MRU in clinical practice and reviews advantages and disadvantages of MRU compared to CTU.

Abstract
PURPOSE Computed tomography urography (CTU) has emerged as the modality of choice for imaging the urinary tract within the past few decades. It is a powerful tool that enables detailed anatomic evaluation of the urinary tract in order to identify primary urothelial malignancies, benign urinary tract conditions, and associated abdominopelvic pathologies. As such, there have been extensive efforts to optimize CTU protocol. METHODS This article reviews the published literature on CTU protocol optimization, including contrast bolus timing, dose reduction, reconstruction algorithms, and ancillary practices. CONCLUSION There have been many advances in CTU techniques, which allow for imaging diagnosis of a wide spectrum of diseases while minimizing radiation dose and maximizing urinary tract distension and opacification.

Abstract
INTRODUCTION To propose an update of the French guidelines from the national committee ccAFU on upper tract urothelial carcinomas (UTUC). METHODS A systematic Medline search was performed between 2016 and 2018, with regards to the diagnosis, the options of treatment and the follow-up of UTUC, to evaluate the different studies with levels of evidence. RESULTS The diagnosis of this rare disease is based on CT-scan acquisition during excretion and ureteroscopy with histological biopsies. Radical nephroureterectomy (RNU) remains the gold standard for surgical treatment, nevertheless a conservative endoscopic approach can be proposed for low-risk diseases: unifocal tumour, possible complete resection low-grade and lack of invasion on CT-scan. Close monitoring with endoscopic follow-up (flexible ureteroscopy) in compliant patients is therefore necessary. After RNU, bladder instillation of chemotherapy is recommended in order to reduce the risk of bladder recurrence. An adjuvant chemotherapy is recommended after RNU in pT2-T4 N0-3 M0 disease. CONCLUSION These updated guidelines will contribute to increase the level of urological care for diagnosis and treatment of UTUC.

Abstract
Upper urinary tract urothelial carcinoma is staged using the TNM classification of malignant tumors. Preoperative TNM is important for treatment planning. Computed tomography urography is now widely used for clinical survey of upper urinary tract carcinoma because of its diagnostic accuracy. Computed tomography urography is recommended as the first-line imaging procedure in several guidelines. Several reports stated that computed tomography urography is also useful for staging. However, no educational and practical reviews detailing the T staging of upper urinary tract urothelial carcinomas using imaging are available. We discuss the scanning protocol, T staging using computed tomography urography, limitations, magnetic resonance imaging, computed tomography comparison and pitfalls in imaging of upper urinary tract urothelial carcinoma. A recent study reported the high diagnostic accuracy of computed tomography urography with respect to T3 or higher stage tumors. To date, images that show a Tis-T2 stage have not been reported, but various studies are ongoing. Although magnetic resonance imaging has lower spatial resolution than computed tomography urography, magnetic resonance imaging can be carried out without radiation exposure or contrast agents. Magnetic resonance imaging also offers the unique ability of diffusion-weighted imaging without contrast agent use. Some researchers reported that diffusion-weighted imaging is useful not only for detecting lesions, but for predicting the T stage and tumor grade. We recommend the appropriate use of computed tomography and magnetic resonance while considering the limitations of each modality and the pitfalls in upper urinary tract urothelial carcinoma imaging.

Abstract
PURPOSE Imaging features of immune-mediated genitourinary diseases often overlap, and the same disease may manifest in different ways, so understanding imaging findings in the context of the patient's entire clinical picture is important in providing the correct diagnosis. METHODS In this article, diseases mediated by the immune system which affect the genitourinary system are reviewed. Examples of immune-mediated genitourinary disease including IgG4-related disease, post-transplant lymphoproliferative disorder, immunodeficiency-associated lymphoproliferative disorder due to immunosuppressive and immunomodulatory medications, lymphoma, leukemia, myeloma, amyloidosis, and histiocytosis. RESULTS Clinical and imaging features will be presented which may help narrow the differential diagnosis for each disease. CONCLUSION Recognition of immune-related genitourinary disease is important for appropriate medical management as they may mimic other diseases both by imaging and clinical presentation.

Abstract
Hematuria evaluation remains a common problem, particularly in patients who smoke and are at risk for urothelial tumors. Lifetime surveillance of the urothelium is often required once urothelial cancer is diagnosed. Computed tomography urography (CTU) has exquisite sensitivity and specificity for identification of renal and urothelial lesions. The examination is well accepted by patients and physicians. Possible harms include radiation exposure and contrast-induced nephropathy. MR imaging is also an accurate test, but requires longer exam times, and may not demonstrate stones. We present the technical and interpretation skills required to use MR urography and CTU effectively.

Abstract
BACKGROUND Staging of bladder cancer, hematuria as well as the evaluation of unclear findings of the kidneys and ureters are the most frequent indications for imaging of the upper urinary tract (UUT). Endourological assessment of the UUT is much more invasive compared to imaging of the bladder, raising the question of the optimal imaging technique. Several technical improvements regarding computed tomography (CT) as well as magnetic resonance imaging (MRI) were implemented in recent years. OBJECTIVES To compare the efficacy and limitations of the most important imaging techniques regarding the UUT. MATERIALS AND METHODS Systematic review of the literature and current German, European, and American guidelines regarding bladder cancer, urothelial carcinoma of the UUT and hematuria. RESULTS The CT-based urography has superseded excretory urography and is the first choice for imaging of the UUT. In case of contraindications, MRI is a feasible alternative. In all cases, a urography phase is indispensable. CONCLUSIONS Imaging of the UUT has to be used in a reasonable combination together with endourological methods and cytology. Optical coherence tomography, confocal laser endomicroscopy and scientific innovations such as radiomics might improve UUT imaging and differential diagnosis of UUT lesions in the future.

Abstract
Ureteral pseudodiverticulosis is a relatively rare condition and has been diagnosed by retrograde urography and excretory urography. Ureteral pseudodiverticulosis is also suspected to be a potential risk factor for the development of urothelial carcinoma. We report the case of a male in his 70 s who was suspected to have right ureteral pseudodiverticulosis accompanied by multifocal urothelial carcinoma based on CT urography findings. After surgery, the pathological findings confirmed the presence of ureteral pseudodiverticulosis and multifocal urothelial carcinoma in his right ureter and bladder. To the best our knowledge, this is the first reported case of ureteral pseudodiverticulosis with concurrent urothelial carcinoma detected by CT urography. Since CT urography has replaced excretory urography as the first-line imaging test for investigating patients with high risk for upper tract urothelial carcinoma, it is important to recognize the characteristic findings of ureteral pseudodiverticulosis on CT urography.

Abstract
INTRODUCTION Staging of upper tract urothelial carcinoma (UTUC) remains a dilemma due to imaging and biopsy limitations leading to understaging. We seek to determine the accuracy of endoluminal ultrasound (ELUS) for clinical staging of UTUC. MATERIALS AND METHODS Patients evaluated for UTUC underwent retrograde pyelography, ureteroscopy, and ELUS. ELUS was performed using mechanical radial scanning at 20 MHz in B-mode with a 5F probe. Cine clips were evaluated by 2 radiologists blinded to ureteroscopic and pathology findings. Results were compared to pathology from nephroureterectomy. Inclusion criteria were patients who underwent nephroureterectomy without pretreatment or managed endoscopically for cTa-1 disease and were without recurrence for >1 year. RESULTS From 2008 to 2013, 53 patients underwent ELUS without complication. Twenty-seven patients met inclusion criteria with conclusive ELUS imaging. ELUS accurately identified 16 of 21 patients with non-muscle invasive (MI) disease (18 pTa, 2 pT1, 1 CIS) and 1 of 6 patients with at least MI disease (2 pT2, 4 pT3). For MI disease, the positive predictive value (PPV), negative predictive value, and accuracy was 76.2%, 16.7%, and 63%, respectively, while for non-organ confined (OC) disease results were 0%, 81.8%, and 66.7%, respectively. CONCLUSIONS With current technique and instrumentation, ELUS may prove useful in select cases to confirm findings of non-MI and OC disease. However, it has insufficient PPV for stage pT2-3 disease. Further studies and better instrumentation are needed before incorporation into clinical practice.

The diagnostic ureteroscopy before radical nephroureterectomy in upper urinary tract urothelial carcinoma is not associated with higher intravesical recurrence. World J Surg Oncol 2018; 16:135.

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
We herein report a rare case of mucinous tubular and spindle cell carcinoma (MTSCC) in an 80-year-old woman. A well circumscribed tumor located on the right kidney was discovered incidentally as a result of screening non-contrast CT. Fluorodeoxyglucose positron emission tomography (FDG PET)/CT showed the increased tracer accumulation in the tumor. The histological diagnosis was MTSCC, which is a rare and only recently established subtype of the malignant renal cell carcinoma (RCC). The present case suggests the clinical benefit of a high uptake of FDG combined with enhanced contrast CT in the differentiation of MTSCCs and other RCCs.

Abstract
Background The non-invasive Cxbladder urine test system has demonstrated clinical utility in ruling out urothelial carcinoma (UC) in patients with asymptomatic microscopic hematuria (AMH), suggesting that the number of invasive diagnostic tests, including cystoscopy, used in this patient population may be reduced by Cxbladder testing prior to conducting a full urological work-up. The aim of this study was to demonstrate the enhanced clinical utility of communicating objective information on diagnostic decisions made by individual physicians on individual patients with AMH. Methods Three hundred ninety-six physician-patient decisions were generated from twelve participant physicians evaluating real world case notes from the same 33 patients presenting with AMH. Each physician reviewed and recommended diagnostic tests and procedures based on each patient’s referral data and then re-evaluated their clinical recommendation following disclosure of the non-invasive Cxbladder urine test result. Changes assessed were the total number of requested diagnostic procedures and the number of invasive procedures, including cystoscopy, following addition of information from Cxbladder in the Triage and Triage and Detect modalities. Results Physicians made significant changes to their diagnostic behavior for patients with AMH when presented with Cxbladder test results, including a reduction in the number of total and invasive procedures including cystoscopy for individuals identified as having a low probability of UC. The intensity of investigation was targeted and increased, including use of total procedures and cystoscopy, for patients identified by Cxbladder tests as having a high probability of UC: urologists increased the level of investigation for both total procedures and invasive procedures. The outcome resulted in patients with a high risk of UC receiving appropriate guideline-recommended invasive diagnostic tests. Patients who tested negative were offered fewer and significantly less invasive procedures. This change in physician behavior results in an increased clinical and patient utility, lower risk of missed UC and invasive test-related harm incidents. Conclusions This study demonstrated the potential for increased clinical resolution and significantly enhanced patient management, when physicians consider Cxbladder test results in their clinical evaluation. The change in physician behavior led to more appropriate diagnostic procedure selection and resource allocation to the benefit of both patients and healthcare systems.

Abstract
Malignancies of the urinary tract (kidney, ureter, and bladder) are distinct clinical entities. Hematuria is a unifying common presenting symptom for these malignancies. Surgical management of localized disease continues to be the mainstay of treatment, and early detection is important in the prognosis of disease. Patients often require life-long follow-up and assessment for recurrence.

Abstract
While urothelial carcinoma is a very common tumor, involvement of the upper tract is relatively uncommon. Consequently, there are no consensus imaging recommendations for upper tract disease. CT urography is the dominant imaging modality for the upper tract, but despite its excellent performance characteristics and being widely accepted as standard of care there is great variability in how CTU exams are performed across practices. MR urography has limited current application, but has the potential to become more mainstream in the future with continued technical advances. Upper tract urothelial carcinoma can manifest as a variety of appearances: a papillary lesion, focal wall thickening, focal enhancement, or as an infiltrative lesion. Pelvicalyceal location is about twice as common as in the ureter. Tumors in the pelvicalyceal location often manifest as an irregular enhancing soft tissue attenuation filling defect, and may be sessile or polypoid in morphology. Within the ureter, 73% are located in the distal segment.

Abstract
Introduction This study aimed to demonstrate the clinical utility of non-invasive multigene Cxbladder urine tests in reducing the overall number of diagnostic tests and invasive procedures used in the clinical evaluation of patients presenting with microhematuria, a key symptom of urothelial carcinoma (UC). There is a belief that using non-invasive molecular diagnostic tests in patients with hematuria may lead to patients undergoing unnecessary and costly invasive procedures that can cause adverse events and decrease patient quality of life. The objective of this study was to determine whether or not this was the case, using Cxbladder. Methods Data from 396 patient-by-urologist interactions generated 792 decision points from a standardized cohort of 33 patients evaluated by 12 urologists. Participant physicians recommended a selection of tests and procedures based on referral data, then reviewed and amended their recommendations in the context of diagnostic information from Cxbladder used in the Triage and Triage and Detect clinical modalities. Results All urologists changed their diagnostic behavior in at least one patient case with the addition of Cxbladder results. The total number of diagnostic procedures was reduced by 5% and 25% following disclosure of results from Cxbladder in the Triage and the Triage and Detect modalities, respectively. The total number of requested invasive procedures was reduced from 425 at referral to 379 (−11%) and 292 (−31%) following disclosure of Cxbladder information in the Triage and Triage and Detect modalities, respectively. Conclusions Urologists made compelling changes to their clinical decision-making when they were provided with Cxbladder results for patients presenting with hematuria. Cxbladder provides an increase in clinical utility by focusing the use of invasive diagnostic procedures to appropriate patients, reducing both the total number and number of invasive procedures used in the clinical management of patients with hematuria, thereby improving the diagnostic experience and outcomes for patients.

Abstract
BACKGROUND Detailed information is not currently available on the incidence, natural course, and management of asymptomatic abnormal prostate findings incidentally detected by radiologic evaluations after BCG therapy for non-muscle-invasive bladder cancer patients. METHODS We identified 38 patients who were evaluated by contrast-enhanced CT scans before TUR-BT and after BCG therapy between 2006 and 2012. We evaluated the clinical courses of patients with abnormal radiologic findings of the prostate gland after BCG therapy. RESULTS Abnormal findings on CT scans were found in the prostate glands of 11 of the 38 patients examined (28.9%), none of whom exhibited any sign or symptom associated with prostatitis. Abnormal findings included a low attenuation area (n = 6, 15.8%), contrast enhancement (n = 3, 7.9%), and a low attenuation area and contrast enhancement in the prostate gland (n = 2, 5.3%). During the follow-up, abnormal prostate findings disappeared spontaneously in most cases without any anti-bacterial or anti-tuberculous drug treatments. No significant differences were observed in patient clinical backgrounds, with the exception of post-BCG prostate volumes, between patients with and without abnormal CT findings. Furthermore, no significant differences were noted in the incidence of the adverse effects of BCG therapy, tumor recurrence rates, or progression rates between patients with and without abnormal CT findings of the prostate gland after BCG therapy. CONCLUSIONS Asymptomatic abnormal prostate findings incidentally detected by CT after BCG therapy are not rare, and these disappear over time during the follow-up period without any treatment.

Abstract
(Introduction and objectives) Radical nephroureterectomy with complete distal ureterectomy is the standard therapy for upper tract urothelial malignancy. Segmental ureterectomy with ueteroneocytostomy is an alternative for distal ureteral carcinoma. We describe extravesical complete distal ureterectomy combined by transurethral bladder cuff excision with frozen-section analysis. (Patient and methods) Since December 2008, 11 patients (median age 77 year old, male 10, female 1, right 10, left 1) with solitary distal ureteral carcinoma who had mild hydronephrosis of ipsilateral kidney remaining renal function on enhanced CT. Under general anesthesia, the patient was placed in lithotomy position, rigid cystoscopy was inserted into the bladder. Cold punch biopsy of 4 sites of bladder mucosa 5 mm away from ureteral orifice (12, 3, 6, 9 o'clock) was carried out and sent to frozen-section analysis. Use resectoscopy with needle-type electrode, incise the bladder mucosa along the biopsy sites circumferentially and incise submucosa tissue around the ureteral orifice deeply enough to detach intramural ureter. Then lower abdominal midline incision was made. After entering the retroperitoneal space, the ureter was dissected and ureteral margin was sent to frozen-section analysis. The distal ureter was dissected until the margin of bladder mucosa incised by transurethrally. After ascertainment of no cancer cell in the frozen-section, close the defect in the bladder. Then the ureter was re-implanted into the bladder by extravesical approach. (Results) Median estimate blood loss was 150 ml (40-350 ml) and median operative time was 258 min (170-317 min.). No patients in our series required a blood transfusion. The mean tumor size was 20+/- 4.4 mm. Pathological T stage was Ta 3, T1 3, T2 2 and T3 3. No positive surgical margin was noted. Mean serum creatinine before and 1 month after surgery was 1.05+/- 0.21 mg/dl and 089+/- 0.13 mg/dl. Mean eGFR before and 1 month after surgery was 54.1+/- 11.4 and 63.4+/- 8.4. Median followup was 35 months (range 4 to 93). Although there were two patients who died from distant metastatic disease, no patients have encountered cancer recurrence in the remained ipsilateral upper urinary tract. (Conclusions) Segmental ureterectomy combined by transurethral bladder cuff excision with frozen-section analysis could perform complete resection of distal ureteral carcinoma and preserve ipsilateral renal function. This technique is feasible for patients with distal ureteral carcinoma as an optional treatment. Better preservation of renal function can lead to increased tolerance of cisplatin-based adjuvant or salvage chemotherapy.

Abstract
INTRODUCTION The purpose was to propose an update of the french guidelines from the national committee CCAFU on upper tract urothelial carcinomas (UTUC). METHODS A systematic Medline search was performed between 2013 and 2016, as regards diagnosis, options of treatment and follow-up of UTUC, to evaluate different references with levels of evidence. RESULTS The diagnosis of this rare pathology is based on CT-scan acquisition during excretion and ureteroscopy with histological biopsies. Radical nephroureterectomy (RNU) remains the gold standard for surgical treatment, nevertheless a conservative endoscopic approach can be proposed for low risk lesion: unifocal tumour, possible complete resection and low grade and absence of invasion on CT-scan. Close monitoring with endoscopic follow-up (flexible ureteroscope) in compliant patients is therefore necessary. After RNU, bladder instillation of chemotherapy is recommended to reduced risk of baldder recurrence. The place of systemic therapy (adjuvant and neoadjuvant chemotherapy) remains to define. CONCLUSION These updated guidelines will contribute to increase the level of urological care for diagnosis and treatment for UTUC. © 2016 Elsevier Masson SAS. All rights reserved.
