Abstract
Metastatic urothelial carcinoma is a rare cause of pleural effusions. We report a case of urothelial carcinoma of the upper urinary tract in an oldest-old male patient, a smoker, with situs inversus totalis, that presented uniquely with malignant pleural effusion at presentation without evidence of a primary tumor on imaging. Cytological smears of the massive left pleural effusion revealed epithelioid neoplastic cells arranged in short cords, small-to-large clusters, and raspberry-like morules, mimicking mesothelioma; cell block preparations highlighted the presence of tubules and nest-like structures. The tumor cells showed a high nuclear-to-cytoplasmic ratio, nuclear grooves, and mitotic figures. Cytomorphologic features coupled with the immunophenotype of neoplastic cells (p63, GATA3, and uroplakin II positive) allowed the diagnosis of metastatic urothelial carcinoma and a possible nested subtype. These findings were supported by a total body computed tomography (CT) showing no evidence of a mass in the bladder or elsewhere in the urinary tract but a concentric parietal thickening of the proximal left ureter, suggesting malignancy. To our knowledge, a malignant effusion as a primary manifestation of urothelial carcinoma with nest-like features originating in the upper urinary tract has never been described previously. Our case focuses on the value of cell block in the working-up of neoplastic effusions by revealing the architectural pattern of an uncommon malignancy and the correlation between cytopathology and imaging gross findings to reach an accurate diagnosis.

Abstract
Objectives This study aimed to evaluate the cumulative incidence of upper tract urothelial carcinoma (UTUC) recurrence and identify its risk factors in patients who underwent radical cystectomy (RC). Patients and methods We performed RC on 385 patients between September 2002 and February 2020. After excluding 20 patients-13 with simultaneous nephroureterectomy, 6 with distal ureteral stump positivity and 1 with urachal cancer-365 patients were included in the analysis. To predict UTUC recurrence, we examined the cancer extension pattern in cystectomy specimens and categorized them into three types: cancer located only in the bladder (bladder-only type), cancer extending to the urethra or distal ureter (one-extension type) and cancer extending to both the urethra and distal ureter (both-extension type). We determined hazard ratios for UTUC recurrence for each covariate, including this cancer extension pattern. Results Of the 365 patients, 60% had the bladder-only type, 30% had the one-extension type and 10% had the both-extension type. During a median follow-up period of 72 months for survivors, UTUC recurred in 25 of the 365 patients, with cumulative incidences of 3.7% at 5 years and 8.3% at 10 years. The median interval from cystectomy to recurrence was 65 months (interquartile range: 36-92 months). In the multivariate analysis, the extension pattern was a significant predictor of UTUC recurrence. The hazard ratios for UTUC recurrence were 3.12 (95% confidence interval [CI] = 1.15-8.43, p = 0.025) for the one-extension type and 5.96 (95% CI = 1.98-17.91, p = 0.001) for the both-extension type compared with the bladder-only type. Conclusions The cancer extension pattern in cystectomy specimens is predictive of UTUC recurrence. A more extensive cancer extension in cystectomy specimens elevates the risk of subsequent UTUC recurrence. Intensive long-term monitoring is essential, particularly for patients with the both-extension type.

Abstract
BACKGROUND The Paris System for Reporting Urine Cytology (TPS) recommends diagnostic criteria for urinary tract cytology, focusing primarily on the detection of high-grade urothelial carcinoma (HGUC) in the lower urinary tract. The second edition of TPS (TPS 2.0), published in 2022, extends these recommendations to the upper urinary tract (UUT); however, there is a lack of comprehensive data on this subject. METHODS In total, 223 consecutive UUT cytology specimens from 137 patients were retrieved and reclassified according to TPS 2.0 criteria and were compared with the original diagnosis based on the conventional system (CS). Histologic follow-up within a 3-month period was conducted for 43 patients. RESULTS Histologic follow-up revealed 30 HGUCs, five low-grade urothelial carcinomas (LGUCs), and eight nonneoplastic fibrotic tissues. The risk of high-grade malignancy for each TPS diagnostic category was 16.7% for nondiagnostic/unsatisfactory, 2.3% for negative for HGUC (NHGUC), 42.1% for atypical urothelial cells, 50.0% for suspicious for HGUC (SHGUC), and 81.8% for HGUC. In all five cases of histologically diagnosed LGUC, the cytologic diagnosis was NHGUC. When SHGUC/HGUC was considered positive, the diagnostic accuracy of TPS had 63% sensitivity, 95% specificity, a 90% negative predictive value, and a 79% positive predictive value, which were better than those of CS. In addition, the TPS indices did not differ significantly between the specimens obtained before and after the application of contrast reagents. CONCLUSIONS TPS implementation improved the accuracy of UUT cytology in predicting histologic HGUC, which was unaffected by the application of contrast reagents. These data indicate the usefulness of TPS for UUT cytology in routine clinical settings.

Abstract
Upper urinary tract urothelial carcinoma (UTUC) is an uncommon malignancy involving the renal pelvis and ureter. Careful pathologic analysis plays a critical role in the diagnosis and clinical management of UTUC. In combination with clinical and radiologic evaluation, pathologic features can be used to stratify patients into low-risk and high-risk groups. This risk stratification can help clinicians select the optimal treatment for patients with UTUC, such as kidney-sparing (conservative) treatment, radical nephroureterectomy or ureterectomy, and perioperative systemic therapy. However, due to the technical difficulty of obtaining sufficient tissue from the upper urinary tract, it is often challenging for pathologists to accurately grade the tumor and assess tumor invasion in small biopsy specimens. Although the majority of UTUCs are pure urothelial carcinoma, a considerable subset of UTUCs show histologic subtypes or divergent differentiation. Recent studies have identified genetically distinct molecular subtypes of UTUC by examining DNA, RNA, and protein expression profiles. The prognosis of pT3 UTUC, particularly renal pelvic UC, remains controversial, and several studies have proposed subclassification of pT3 UTUC. Lynch syndrome is a significant risk factor for UTUC, and screening tests may be considered in young patients and those with familial histories of the disease. Despite significant progress in recent years, several issues remain to be addressed in the pathologic diagnosis, molecular classification, and treatment of UTUC.

Abstract
OBJECTIVE Cytologic evaluation of the upper urinary tract (UUT) can be challenging due to instrumentation artefacts. This study retrospectively reviewed UUT specimens using The Paris System for Reporting Urinary Cytopathology, second edition (TPS 2.0), compared it with the original reporting system (ORS) and correlated it with histopathologic follow-up. METHODS An institutional database was reviewed for the UUT biopsy/resection histopathologic specimens, and we included 52 UUT cytology specimens pertinent to these cases in the study. These specimens were blindly reviewed and reclassified using TPS 2.0. The correlation between TPS 2.0, ORS and histopathologic follow-up was assessed. RESULTS The UUT cytology specimens corresponded to 21 (40.4%) high-grade urothelial carcinoma (HGUC), 27 (51.9%) low-grade urothelial carcinoma (LGUC) and 4 (7.7%) benign cases on follow-up. For HGGC cases, the associated TPS categories included unsatisfactory (n = 1, 4.8%), negative for HGUC (NHGUC; n = 3, 14.3%), atypical urothelial cells (AUC; n = 6, 28.6%), suspicious for HGUC (SHGUC; n = 3, 14.3%) and HGUC (n = 8, 38.1%), while ORS categorised the specimens as unsatisfactory (n = 1, 4.8%), negative for malignant cells (NFMC; n = 3, 14.3%), AUC (n = 5, 23.8%), low-grade urothelial carcinoma (LGUC; n = 0, 0%), SHGUC (n = 5, 23.8%) and HGUC (n = 7, 33.3%). The risks of high-grade malignancy among cytologic categories were similar between ORS and TPS (p > 0.05). The majority of LGUC were classified as AUC similarly by ORS and TPS (55.6% vs. 59.3%). CONCLUSIONS Our study demonstrated comparable performance between TPS 2.0 and ORS for UUT cytology specimens. Cytological diagnosis of UUT specimens remains challenging, especially for LGUC.

Abstract
Urine expulsion from the upper urinary tract is a necessary process that eliminates waste, promotes renal filtration and prevents nephron damage. To facilitate the movement of urine boluses throughout the upper urinary tract, smooth muscle cells that line the renal pelvis contract in a coordinated effort to form peristaltic waves. Resident pacemaker cells in the renal pelvis are critical to this process and spontaneously evoke transient depolarizations that initiate each peristaltic wave and establish rhythmic contractions. Renal pacemakers have been termed atypical smooth muscle cells due to their low expression of smooth muscle myosin and poor organization of myofilaments compared to typical (or contractile) smooth muscle cells that perform peristalsis. Recent findings discovered that pacemaker cells also express the tyrosine kinase receptor PDGFRα, enabling their identification and purification amongst other renal pelvis cell types. Improved identification methods have determined that the calcium-activated chloride channel, ANO1, is expressed by pacemaker cells and may contribute to spontaneous depolarization. A greater understanding of pacemaker and peristaltic mechanisms is warranted since aberrant contractile function may underlie diseases such as hydronephrosis, a deleterious condition that can cause significant and irreversible nephron injury.

Abstract
Crossed fused renal ectopia (CFRE) constitutes a rare congenital anomaly of the urinary tract, typically characterized by its predominantly asymptomatic nature and frequent incidental discovery. This case report delineates the clinical profile of a 56-year-old male admitted to our Prostate Cancer Outpatient Clinic due to elevated prostate-specific antigen (PSA) levels, ultimately leading to the diagnosis of prostate cancer. The patient was asymptomatic, with no family or surgical background. Notably, a fused ectopic kidney was incidentally identified during the staging process involving abdominal computed tomography (ACT) scanning. Remarkably, no additional abnormalities of the urinary tract or renal dysfunction manifested in this specific case. The significance of this report lies in the underscored emphasis on the importance of employing precise imaging techniques and tailored management strategies for patients harboring such anatomical variations.

Abstract
Nested urothelial carcinoma (NUC) and large nested urothelial carcinoma (LNUC) of the upper urinary tract are exceedingly rare. This has contributed to the paucity of information regarding their clinicopathological and molecular characteristics. To address this knowledge gap, we explored the largest cohort to date of these rare tumors, comprising resection specimens of 10 LNUC and 7 NUC, from 7 participating institutions. Clinicopathological data were retrieved and documented. Whole exome sequencing and RNA sequencing were performed on the Illumina NovaSeq 6000 sequencer. The data generated were analyzed using the genome analysis toolkit pipeline. Somatic mutations were annotated using funcotator tool to identify pathogenic/likely pathogenic variants. Tumor mutational burden was calculated using python-based "pyTMB" tool. Microsatellite instability analysis was done using MSIsensor2 and the Idylla platform. Differential expression analysis of genes in LNUC and NUC along with mRNA expression-based molecular subtyping was performed by analyzing expression pattern of markers used in The Cancer Genome Atlas subclassification of bladder carcinoma. Both tumor types were more common in older males, were unifocal, and occurred more commonly mixed with minor components of predominantly conventional urothelial carcinoma. Overlying low-grade papillary urothelial carcinoma was significantly more common in LNUC (P = .034). On follow-up (LNUC: median, 10 months; range, 3-84 months; NUC: median, 9 months; range, 2-48 months), LNUC had better clinical outcomes (P = .031). Pathogenic mutations in FGFR3 and PIK3CA were significantly more common in LNUC (P = .049 and P = .044, respectively), with the latter present exclusively in LNUC. Seventy-five percent of the cases showed tumor mutational burden of <10, and all cases were microsatellite-stable. FGFR3 mutations were also more common in low-stage tumors. This study expands on the clinicopathological spectrum of NUC and LNUC of the upper urinary tract and is the first to comprehensively analyze the molecular profile of these tumors, highlighting pathogenic genetic alterations of potential therapeutic and prognostic value.

Abstract
Current guidelines recommend endoscopic management (EM) for patients with low-risk upper urinary tract urothelial carcinoma, as well as those with an imperative indication. However, regardless of the tumor risk, radical nephroureterectomy is still mainly performed worldwide despite the benefits of EM, such as renal function maintenance, no hemodialysis requirement, and treatment cost reduction. This might be explained by the association of EM with a high risk of local recurrence and progression. Furthermore, the need for rigorous patient selection and close surveillance following EM may be relevant. Nevertheless, recent developments in diagnostic modalities, pathological evaluation, surgical devices and techniques, and intracavitary regimens have been reported, which may contribute to improved risk stratification and treatments with superior oncological outcomes. In this review, considering recent advances in endourology and oncology, we propose novel treatment strategies for optimal EM.

Abstract
Introduction: Electromotive drug administration (EMDA) delivers a drug deeply into targeted tissues, such as the bladder. EMDA has never been applied to the ureter. Methods: In four in vivo porcine ureters, a unique EMDA catheter containing a silver conducting wire was advanced for the infusion of methylene blue. In two ureters, a pulsed current was delivered through an EMDA machine, whereas the other two ureters served as a control. After 20 minutes of infusion, the ureters were harvested. Results: In the EMDA ureter, there was diffuse staining of the urothelium; penetration of methylene blue occurred in the lamina propria and muscularis propria. In the control ureter, there was only patchy staining of the urothelium. Conclusion: In this first report of ureteral EMDA, a charged molecule penetrated beyond the urothelium into the lamina propria and muscularis propria of the porcine ureter.

α-Actinin4 (ACTN4), an isoform of non-muscular α-actinin, is involved in enhancing cell motility and promoting cancer infiltration and metastasis in various cancers. However, information remains limited regarding the pathological significance of ACTN4 expression in upper urinary tract urothelial carcinomas (UUTUCs). We obtained tumor samples from 168 consecutive patients with newly diagnosed UUTUCs (92 with renal pelvic cancers and 76 with ureteral cancers), who were treated with nephroureterectomy or partial ureterectomy, and analyzed the expression of the ACTN4 protein and the amplification of ACTN4 using immunohistochemistry and fluorescence in situ hybridization (FISH), respectively. The median follow-up duration was 65 months. Among 168 cases, 49 (29%) showed ACTN4 protein overexpression and 25 (15%) showed copy number gain (≥4 copies per cell) of ACTN4. The copy number gain of ACTN4 detected using FISH significantly correlated with ACTN4 protein overexpression and several adverse clinicopathological factors, including higher pathological T stage, lymphovascular invasion, lymph node metastasis, positive surgical margin, concomitant subtype histology, and non-papillary gross finding. Cox univariate regression analyses revealed that both copy number gain of ACTN4 and ACTN4 protein overexpression were significant risk factors for extraurothelial recurrence and death (each p < 0.0001), but multivariate analysis revealed that only copy number gain of ACTN4 was an independent risk factor for extraurothelial recurrence and death (p = 0.038 and 0.027, hazard ratio = 2.16 and 2.17, respectively). This is the first study demonstrating the aberrant expression status of ACTN4 in UUTUC and indicating its putative usefulness as a prognostic indicator in patients with UUTUC.

Abstract
BACKGROUND To explore the application value of intraoperative imaging by indocyanine green (ICG) injection through the collection system of the urinary tract for Da Vinci Xi robot navigation in complex surgeries on the upper urinary tract. METHODS Data of 14 patients who underwent complex surgeries of the upper urinary tract post-ICG injection through the collection system of the urinary tract in combination with Da Vinci Xi robot navigation in the Tianjin First Central Hospital between December 2019 and October 2021 were analyzed in this retrospective study. The operation duration, estimated blood loss, and exposure time of ureteral stricture to ICG were evaluated. The renal functions and tumor relapse were evaluated after surgery. RESULTS Of the fourteen patients, three had distal ureteral stricture, five had ureteropelvic junction obstruction, four presented duplicate kidney and ureter, one had a giant ureter, and one presented an ipsilateral native ureteral tumor after renal transplantation. The surgeries in all patients were successful, with no conversion to open surgery. In addition, no injury to the surrounding organs, anastomotic stenosis or leakage, or ICG injection-related side effects were detected. Imaging at 3 months post-operatively revealed improved renal functions compared to those before the operation. No tumor recurrence or metastasis was observed in patient 14. CONCLUSION Fluorescence imaging compensating for the inadequacy of tactile feedback in the surgical operating system has advantages in identifying the ureter, determining the site of ureteral stricture, and protecting the blood flow for the ureter.

Abstract
During endoscopic procedures for suspected urothelial tumors of the upper urinary tract, radiographic imaging using an iodinated contrast medium is often required. However, following ureteropyelography, we detected changes in cytology characteristics not correlating with real cytology findings in naive urine. The aim of our study was to assess cytology changes between naive and postcontrast urine according to The Paris System of cytology classification. Methods: We prospectively assessed urine samples from 89 patients (23 patients with histologically proven urothelial cancer and 66 healthy volunteers). The absence of malignancy was demonstrated by CT urography and/or ureteroscopy. The study was single blind (expert cytopathologist) and naïve Paris system for urine cytology assessment was used. Furthermore, additional cytological parameters were analyzed (e.g., specimen cellularity, degree of cytolysis, cytoplasm and nucleus color, chromatin and nucleo-cytoplasmic ratio). Results: Our study showed statistically significant differences when comparing naïve and postcontrast urine in healthy volunteers (only 51 % concordance, p = 0.001) versus malignant urine specimens (82 % concordance). The most important differences were in the shift from The Paris System category 2 (negative) to 1 (non-diagnostic) and from category 2 (negative) to 3 (atypia). Other significant changes were found in the assessment of specimen cellularity (p = 0.0003), degree of cytolysis (p = 0.001), cytoplasm color (p = 0.003), hyperchromasia (p = 0.001), course chromatin (p = 0.002), nucleo-cytoplasmatic ratio (p = 0.001) and nuclear borders’ irregularity (p = 0.01). Conclusion: Our unique study found crucial changes in the cytological assessment of naive and postcontrast urine and we confirm that postcontrast urine is more often assessed as abnormal, suspect or non-diagnostic. Therefore, before urine collection for cytology, the clinician should avoid administration of iodinated contrast into the urinary tract.

Abstract
OBJECTIVES To evaluate S-phase fraction as a predictor of invasiveness and cancer-specific survival in upper tract urothelial carcinoma (UTUC). PATIENTS AND METHODS One hundred and fifteen patients having undergone radical nephroureterectomy were analysed with histology in radical nephroureterectomy specimens as reference test and S-phase fraction as index test. Ploidy and S-phase were determined using flow cytometry. Differences in S-phase fraction were calculated between stages, grades (WHO 1999 and 2004 classifications), ploidy and patients that died of UTUC and those who did not. Five- and 10-year-cancer-specific survivals were calculated. Areas under the ROC curve (AUCs) of S-phase fraction in relation to tumour stage and to death from UTUC were measured. Multiple Cox regression was performed. RESULTS Independent prognostic markers of death from UTUC were S-phase fraction and stage. Correlation between S-phase fraction and risk of dying from UTUC was strong, with a 17% greater risk of death from UTUC with every 1% increase in S-phase fraction, hazard ratio = 1.17, 95% CI = 1.10-1.25, p < 0.001, Spearman's rho ρ = 0.65. AUCs for S-phase fraction as predictors of stage and death from UTUC were 0.8 (95% CI = 0.705-0.894) and 0.77 (95% CI = 0.67-0.87), respectively. Cancer-specific survival was statistically significantly different between stages, ploidy and WHO 1999 grades, but not between WHO 2004 grades. This was also reflected in S-phase fraction, which differed in LG-G1 compared with LG-G2 and in HG-G2 compared with HG-G3. CONCLUSION S-phase fraction was a good test for predicting both invasiveness and cancer-specific survival. Using both WHO 1999 and 2004 classifications, rather than one system alone, had a higher predictive value of cancer-specific survival.

Abstract
The process of urine removal from the kidney occurs via the renal pelvis (RP). The RP demarcates the beginning of the upper urinary tract and is endowed with smooth muscle cells. Along the RP, organized contraction of smooth muscle cells generates the force required to move urine boluses toward the ureters and bladder. This process is mediated by specialized pacemaker cells that are highly expressed in the proximal RP that generate spontaneous rhythmic electrical activity to drive smooth muscle depolarization. The mechanisms by which peristaltic contractions propagate from the proximal to distal RP are not fully understood. In this study, we utilized a transgenic mouse that expresses the genetically encoded Ca2+ indicator, GCaMP3, under a myosin heavy chain promotor to visualize spreading peristaltic contractions in high spatial detail. Using this approach, we discovered variable effects of L-type Ca2+ channel antagonists on contraction parameters. Inhibition of T-type Ca2+ channels reduced the frequency and propagation distance of contractions. Similarly, antagonizing Ca2+-activated Cl- channels or altering the transmembrane Cl- gradient decreased contractile frequency and significantly inhibited peristaltic propagation. These data suggest that voltage-gated Ca2+ channels are important determinants of contraction initiation and maintain the fidelity of peristalsis as the spreading contraction moves further toward the ureter. Recruitment of Ca2+-activated Cl- channels, likely Anoctamin-1, and T-type Ca2+ channels are required for efficiently conducting the depolarizing current throughout the length of the RP. These mechanisms are necessary for the efficient removal of urine from the kidney.

Abstract
This study aims to evaluate the impact of preoperative renal function on oncological outcomes in patients with upper tract urothelial carcinoma (UTUC) who underwent radical nephroureterectomy (RNU). We performed a retrospective analysis of patients who underwent RNU between 2000 and 2012 at six academic centers. The patients were stratified into two groups based on preoperative renal function: eGFR < 60 mL/min/1.73 m2 (chronic kidney disease; CKD) and eGFR ≥ 60 mL/min/1.73 m2 (non-CKD). We investigated oncological outcomes, including overall survival, cancer-specific survival, and progression-free survival dichotomized by preoperative renal function. Multivariable Cox proportional hazards regression was used to determine if preoperative CKD was associated with oncological outcomes. In total, 1733 patients were eligible for the present study (CKD = 707 and non-CKD = 1026). Significant differences were noted in the clinical and pathologic features among the two groups, including age, sex, tumor localization, pathological T stage, tumor grade, and number of patients who received adjuvant chemotherapy. The estimated five-year overall survival (79.4 vs. 67.5%, log-rank p < 0.001), cancer-specific survival (83.5 vs. 73.6%, log-rank p < 0.001), and progression-free survival (74.6 vs. 61.5%, log-rank p < 0.001) were significantly different between the two groups, longer in the non-CKD group. Upon multivariable analysis, preoperative CKD status was associated with increased risk of overall mortality, cancer-specific mortality, and progression (p = 0.010, p = 0.016, and p = 0.008, respectively). UTUC patients with preoperative CKD had a higher risk of poor overall survival, cancer-specific survival, and progression-free survival after RNU than those without CKD.

Abstract
Background Numerous studies have investigated the risk factors of intravesical recurrence (IVR) after radical nephroureterectomy (RNU) in patients with upper urinary tract urothelial carcinoma (UTUC). However, few studies explore the predictors for unfavorable pathological types of IVR following RNU. Methods We retrospectively reviewed 155 patients diagnosed with bladder cancer (BC) following RNU. Binary logistic regression was used for the univariable and multivariable analyses. Nomograms were developed based on the multivariable analysis. The concordance index (C-index) was used to assess the performance of the nomograms. We performed internal validation by generating calibration plots. Results Muscle-invasive BC (MIBC) was significantly correlated with operation interval (p = 0.004) and UTUC T-stage (p = 0.016). Operation interval (p = 0.002) and UTUC T-stage (p = 0.028) were also risk factors for BC > 3 cm. UTUC grade (p = 0.015), operation interval (p = 0.003), and hydronephrosis (p = 0.049) were independent predictors for high-grade BC (HGBC). MIBC (p = 0.018) and surgical approach (p = 0.003) were associated with multifocal IVR. Besides, MIBC and HGBC were associated with UTUC grade (p = 0.009), operation interval (p = 0.001), and hydronephrosis (p = 0.023). Moreover, only operation interval (p = 0.036) was a predictor for BC with at least one unfavorable pathological type. We developed nomograms for MIBC, HGBC, BC > 3 cm, and MIBC and/or HGBC. The calibration curves of the nomograms showed good agreement between the observation and prediction cases. The C-indexes of the nomograms were 0.820 (95% CI, 0.747–0.894), 0.728 (95% CI, 0.649–0.809), 0.770 (95% CI, 0.679–0.861), and 0.749 (95% CI, 0.671–0.827), respectively. Conclusions The current study found that operation interval, UTUC T-stage, UTUC grade, surgical approach, and hydronephrosis are independent predictors for unfavorable pathological types of IVR following RNU. Nomograms based on these predictors were developed and internally validated to assess the risk of developing unfavorable pathological types of IVR. Furthermore, patients at high risk of developing unfavorable pathological types BC may benefit from more active follow-up 1 year after RNU by early detection of IVR.

Abstract
Purpose To determine the safety and feasibility of extraperitoneal laparoscopic extended lymph node dissection (LND) at the time of extraperitoneal laparoscopic radical nephroureterectomy (RNU). Materials and Methods Between May 2018 and March 2019, 39 patients with upper tract urothelial carcinoma (UTUC) received extraperitoneal laparoscopic RNU and concomitant extraperitoneal laparoscopic extended LND. All patients were followed for at least 90 days. Perioperative and pathological data including nodal status and perioperative complications were collected. Results Among all 39 patients, 12 patients had pT1, 6 had pT2, 20 had pT3 disease, and 1 had T4 disease. The median (range) lymph node count was 10 (5–22), with 8 patients having pathologically proven lymph node metastasis. The median (range) operating time was 225 (165–430) min, and the median estimated blood loss was 200 (60–800) ml. The median postoperative hemoglobin loss was 1.6 (0–4.2) g/dl. The median (range) postoperative hospital stays were 6 (3–26) days. Overall, 7 patients experienced minor (Clavien Grade I–II) postoperative complications with five patients having Clavien Grade I complications and two patients having Clavien Grade II complications. No major complication (Clavien grade III–IV) occurred. With a median follow-up of 38 months, a total of 8 patients (20.5%) developed local or distant recurrence and no regional LNs where extended LND were performed had recurrence. Conclusions The present prospective study demonstrated that extraperitoneal laparoscopic extended LND during extraperitoneal laparoscopic RNU for UTUC is a feasible and safe procedure which provides minimal invasion, rapid recovery, and potentially lower risk of regional LN recurrence. Larger prospective clinical trials with survival endpoints are needed to further determine its potential therapeutic benefits.

Abstract
Urothelial carcinomas (UC) arise from the urothelium that covers the proximal urethra, urinary bladder, and the upper urinary tract. In daily routine and clinical trials UC originating from different locations are often treated and investigated in the same manner. However, differences between the two locations seem to be apparent and may question in handling them as a single oncologic entity. In this review we discuss similarities and differences between bladder and upper urinary tract UC and consider their potential impact on treatment strategies. Despite similarities of UC in the bladder (BC) and the upper urinary tract (UTUC), clinicopathologic and molecular differences may question to generally assemble both as a single tumor entity. Treatment standards for UTUC are often adopted from BC. However, a specific investigation in the former may still be meaningful as shown by the example of adjuvant cisplatin based chemotherapy. In conclusion, future investigations should prioritize the understanding of the tumor biology of both BC and UTUC. This may reveal which UTUC can be treated according to treatment standards of BC and in which cases, a separate approach may be more appropriate.

Abstract
Background: Upper urinary tract urothelial carcinoma (UTUC) is the most common malignancy occurring after kidney transplantation (KT) in Taiwan. The aim of this study was to investigate the association between native kidney hydronephrosis and UTUC in post-KT patients. Methods: From 2003 to 2018, we conducted a retrospective cohort study that enrolled 1005 post-KT patients, 67 of whom were subsequently diagnosed with UTUC. We divided patients into two groups based on whether or not they had UTUC. Multivariate analysis and Kaplan-Meier plot were used to evaluate if native kidney hydronephrosis was associated with post-KT UTUC. Results: The total cohort consisted of 612 men (60.9%) and 393 women (39.1%) with a mean age of 48.2 ± 12.0 at KT. The mean follow-up time was 118.6 ± 70.2 months, and mean time from KT to UTUC was 7.53 years. There was a significant gender difference with a female predominance among the UTUC patients (73.1% versus 26.9%, p < 0.001). Native kidney hydronephrosis occurred more frequently in the UTUC group (68.7% versus 4.8%, p < 0.001). Multivariate analysis showed that native kidney hydronephrosis and female gender were significantly associated with UTUC with odds ratios of 35.32 (95% CI, 17.99–69.36; p < 0.001) and 3.37 (95% CI, 1.55–7.29; p = 0.002), respectively. UTUC in the post-KT patients also showed aggressive pathological characteristics and a tendency toward bilateral lesions (41.8%). Conclusions: Native kidney hydronephrosis is significantly associated with post-KT UTUC patients in Taiwan. Native kidney hydronephrosis may be a deciding factor for standard nephroureterectomy and bladder cuff excision in selected patients. Nevertheless, almost half of the patients with kidney hydronephrosis do not present with UTUC at the end of our study.

Abstract
Preoperative renal function is associated with worse outcomes in patients undergoing radical nephroureterectomy (RNU). The purpose of this systemic review and meta-analysis was to determine the association of preoperative renal function with oncological outcome in patients who underwent RNU. We searched articles published up to March 2021 in PubMed, Scopus, and Embase by combining "urothelial carcinoma", "radical nephroureterectomy", and "estimated glomerular filtration rate". We also manually screened the reference list for publications following general guidelines recommended by the preferred reporting items for systematic reviews and meta-analyses (PRISMA) statement. The relationship between preoperative renal function and survival was expressed as overall survival (OS), progression-free survival (PFS), and cancer-specific survival (CSS). This review and meta-analysis included 13 studies involving a total of 4668 patients who received RNU. Pooled analysis showed significant negative association of preoperative renal function with PFS (HR: 1.51, 95% CI: 1.23-1.80, p < 0.00001), CSS (HR: 1.63, 95% CI: 1.38-1.92, p < 0.00001), and OS (HR: 1.22, 95% CI: 1.10-1.35, p < 0.00001). Patients with upper tract urothelial carcinoma (UTUC) who received RNU showed a significant negative association of preoperative renal function with survival.

Abstract
BACKGROUND This study evaluated the impact of sarcopenia and psoas major muscle volume on the survival of patients with upper urinary tract urothelial carcinoma who had undergone radical nephroureterectomy. METHODS We reviewed data from 110 patients treated with radical nephroureterectomy in our department between June 2007 and February 2017. Psoas major muscle volume was quantified based on computed tomography data using Synapse Vincent software. The psoas major muscle volume index was calculated as psoas major muscle volume/height squared (cm3/m2). We analysed relapse-free survival, cancer-specific survival and overall survival after radical nephroureterectomy to identify factors that predicted patient survival. RESULTS The median psoas major muscle volume index was 121.5 cm3/m2, and the psoas major muscle volume index was <100 cm3/m2 in 34 of 110 patients (30.9%). Multivariate analysis indicated that ≥pT3-stage cancer, lymphovascular invasion and a psoas major muscle volume index of <100 cm3/m2 were independent predictors of shorter relapse-free survival, cancer-specific survival and overall survival. Using these factors, patients were stratified into three groups: low, intermediate and high risks for relapse-free survival, cancer-specific survival and overall survival. CONCLUSIONS Low psoas major muscle volume resulting from sarcopenia, high T stage and the presence of lymphovascular invasion was associated with poor survival in patients with urinary tract urothelial carcinoma who had undergone radical nephroureterectomy, supporting the use of psoas major muscle volume as a new objective prognostic marker.

Abstract
Objective To evaluate predictive clinical and histopathological risk factors for bladder cancer recurrence in patients who underwent nephroureterectomy for primary upper urinary tract transitional cell carcinoma (TCC). Subjects and Methods Data of 111 patients, who were diagnosed with upper urinary tract TCC and underwent nephroureterectomy were reviewed A total of 65 patients were included in the study, after excluding 34 patients. Results: Bladder cancer recurrence developed in 20 (30.7%) of the 65 patients under evaluation. The recurrence-free survival rates in the 1st, 3rd, and 5th years were 78.4%, 70.7% and 69.2%, respectively. Lymphovascular invasion and a positive surgical margin were defined as risk factors for bladder cancer recurrence. In addition, patients with multiple tumors and low stage and grade pathology had a high rate of bladder cancer recurrence, although this was not statistically significant. Conclusion After nephroureterectomy, a careful follow-up is required in terms of bladder tumor recurrence especially in patients with a positive surgical margin, lymphovascular invasion, low-grade tumors, or multifocal tumors.

Abstract
Mucosa-associated lymphoid tissue (MALT) lymphomas are a distinctive group of B-cell lymphomas. These lymphomas arise from various anatomic sites and are mainly seen in the gastrointestinal tract, but the primary involvement of the kidney is extremely rare. We report a case of a MALT lymphoma involving the kidney and the renal pelvis. A 56-year-old man presented with a history of hematuria and left flank pain. A computed tomography scan showed a marked tissue densification in the renal sinus, suggesting marked thickening of the urothelium, conditioning deformity of the renal pelvis and calyces. A cystoscopy confirmed a 2-cm papillary lesion on the left lateral aspect of the bladder. The patient underwent laparoscopic radical nephoureterectomy and transurethral bladder resection. The pathological diagnosis was MALT lymphoma in the kidney and urothelial carcinoma of the bladder. The patient was referred to a hematologist and was free of disease at 20 months of follow up without additional treatment.

Abstract
OBJECTIVE To examine the discrepancy between clinical and pathological T stages in patients with urothelial carcinoma of the upper urinary tract treated with radical surgery, and to compare them with the corresponding discrepancy in urothelial carcinoma of the bladder. METHODS We used the Hospital-Based Cancer Registry data in Japan to extract urothelial carcinoma of the bladder cases (n = 3747) and urothelial carcinoma of the upper urinary tract cases (n = 6831), including urothelial carcinoma of the renal pelvis (n = 3295) and urothelial carcinoma of the ureter (n = 3536) with cT1-4N0M0 diagnosed in 2012-2015, histologically confirmed, and treated with radical surgery without chemotherapy or radiotherapy. We compared the T-stage discrepancy among different tumor locations. RESULTS The proportions of overall T-stage discrepancy in the urothelial carcinoma of the renal pelvis (40.8%) and urothelial carcinoma of the ureter (42.9%) groups tended to be higher compared with that in the urothelial carcinoma of the bladder (38.8%) group. The upstaging rate from clinical non-muscle-invasive cancer (≤cT1) to pathological muscle-invasive cancer (≥pT2) was significantly higher in the urothelial carcinoma of the renal pelvis and urothelial carcinoma of the ureter groups compared with the urothelial carcinoma of the bladder group (P = 0.002, P < 0.0001, respectively). Upstaging from clinical organ-confined disease (≤cT2) to pathological non-organ-confined disease (≥pT3) was significantly more frequent in the urothelial carcinoma of the renal pelvis (27.8%, P < 0.0001) and urothelial carcinoma of the ureter (22.3%, P < 0.0001) groups compared with the urothelial carcinoma of the bladder (17.8%) group. CONCLUSION Discrepancy in T staging is significantly higher in patients with urothelial carcinoma of the upper urinary tract compared with those with urothelial carcinoma of the bladder, especially in those with organ-confined disease. As T-stage discrepancy might lead to missed opportunities to carry out perioperative treatment, more accurate diagnostic techniques are required to identify the appropriate urothelial carcinoma candidates for preoperative treatment.

Abstract
Aim To assess trends in the incidence, disease management and survival rates for upper urinary tract urothelial carcinoma (UTUC) in the Netherlands. Materials and methods Patients diagnosed with primary UTUC in the Netherlands between 1993 and 2017 were identified through the population‐based Netherlands Cancer Registry (NCR). Patient and tumour characteristics, as well as information on treatment and vital status, were retrieved from the NCR. Age‐standardized incidence rates were calculated, stratified by age, gender, calendar period and disease stage. Relative survival served as an approximation for cancer‐specific survival. Results We identified 13 314 patients with primary UTUC. The age‐standardized incidence rate increased from 2.0 in 1993 to 3.2 per 100 000 person‐years in 2017, without change in gender distribution. The increase in incidence held for all disease stages except organ‐confined (T1–T2) disease. The most prominent increase was in superficial (Tis/Ta) and metastatic (M+) UTUC, which increased from 0.6 to 1.2 and 0.1 to 0.4 per 100 000 person‐years, respectively. The 5‐year relative survival did not change over time: 57.0% (95% confidence interval 55.9–58.1). Applied treatments were largely the same over the study period, although fewer radical nephroureterectomies and more kidney‐sparing surgeries were performed in the most recent years. The use of peri‐operative intravesical chemotherapy modestly increased. Conclusion Between 1993 and 2017, the age‐standardized incidence of primary UTUC in the Netherlands has increased by more than 50%, but the relative survival of UTUC patients remained unchanged. Preventive measures against exposure to risk factors, early detection of disease, and more efficacious treatment methods are needed to improve outcomes of patients with UTUC.

Abstract
Purpose: We explored whether the modified American Joint Committee on Cancer tumor-node-metastasis prognostic stage group IV can be individualized in a large population-based cohort of surgically treated invasive upper tract urothelial carcinoma (UTUC) patients. Methods: Invasive UTUC patients from the Surveillance, Epidemiology and End Results database (2004-2015) were screened for inclusion. A total of 10,482 eligible cases were identified. Cancer-specific survival (CSS) after surgery was analyzed using Kaplan-Meier plots. Results: According to the most recent pathological prognostic group classification, the 5-year mortality rates of T4NxM0 (n=493), TxN1M0 (n=597), TxN2M0 (n=424) and pTxNxM1 (n=677) patients were 41.1% (95% CI 35.2% to 47.0%), 38.6% (95% CI 33.1% to 44.1%), 40.4% (95% CI 33.0% to 47.8%) and 14.2% (95% CI 9.9% to 18.5%), respectively (T4N0M0 vs. TxNxM1, P<0.001; TxN1M0 vs. TxNxM1, P<0.001; TxN2M0 vs. TxNxM1, P<0.001). Stage IV tumors were subdivided on the basis of the mortality data (Modification 1): stage IVa tumors were considered nonmetastatic (T4NxM0, TxN1-2M0; 5-year CSS 39.9%), and stage IVb tumors were considered metastatic (pTxNxM1; 5-year CSS 14.2%). Stage IV tumors were also subdivided according to the grade classification (Modification 2): stage IVa tumors were considered low grade (T4NxM0, TxN1-2M0, TxNxM1; G1-2; n=141), and stage IVb tumors were considered metastatic (T4NxM0, TxN1-2M0, TxNxM1; G3-4; n=2050). The 5-year CSS rates for stage IVa and IVb patients were 76.3% (95% CI 68.7% to 83.9%) and 31.4% (95% CI 28.5% to 34.3%), respectively (P<0.001). Conclusions: Stage IV patients were stratified into two prognostically different risk groups depending on metastasis or grade. The subclassification of stage IV can increase the level of prognostic detail and individualize the prediction of survival in invasive UTUC patients.

Abstract
Lynch syndrome, known as hereditary nonpolyposis colorectal cancer (HNPCC), is an autosomal-dominant familial cancer syndrome with an increased risk for urothelial cancer (UC). Mismatch repair (MMR) deficiency, due to pathogenic variants in MLH1, MSH2, MSH6, and PMS2, and microsatellite instability, are known for development of Lynch syndrome (LS) associated carcinogenesis. UC is the third most common cancer type in LS-associated tumors. The diversity of germline variants in the affected MMR genes and their following subsequent function loss might be responsible for the variation in cancer risk, suggesting an increased risk of developing UC in MSH2 mutation carriers. In this review, we will focus on LS-associated UC of the upper urinary tract (UUT) and bladder, their germline profiles, and outcomes compared to sporadic UC, the impact of genetic testing, as well as urological follow-up strategies in LS. In addition, we present a case of metastatic LS-associated UC of the UUT and bladder, achieving complete response during checkpoint inhibition since more than 2 years.

Abstract
Background To evaluate the feasibility and effect of upper urinary tract videourodynamics in complex reconstructed upper urinary tract. Methods From January 2016 to December 2018, patients who underwent complex upper urinary tract reconstruction and received upper urinary tract videourodynamics were included in the study. The modified Whitaker test was performed at 3 months after operation. The relative pelvic pressure was defined as the pelvic pressure minus the bladder pressure. Based on the flow rate, the test was divided into physiological phase and high flow phase. The results of pressure and image were classified into 3 types. Successful nephrostomy removal was defined as no symptoms and improved or stable hydronephrosis. Results A total of 12 patients who underwent complex upper urinary tract reconstruction received modified Whitaker test. All tests were successfully completed without adverse reactions. The relative pelvic pressure of 3 patients kept steady near the baseline throughout the examination and was classified into type 1. The pelvic pressure of 7 patients increased as the perfusion continued, and the relative pressure dropped to relative low level due to the peristalsis of ureter (type 2). The pressure of 2 patients increased along with increasing perfusion speed, and the relative pelvis pressure could easily reach 15 cmH2O. The peristalsis of ureter disappeared or appeared very weakly on the video record (type 3). Patients in type 1 (3 cases) and type 2 (7 cases) groups were allowed to remove the nephrostomy tube immediately. Patients in type 3 group needed to keep the nephrostomy for close follow up, and the tubes were removed 2 weeks and 4 weeks after the examination, respectively. None of the 12 patients received further treatment for recurrent symptoms and exacerbation of hydronephrosis. Conclusions The modified Whitaker test is initially safe and feasible in postoperative evaluation of complex upper urinary tract reconstruction surgery. Detailed results can provide more evidence to judge whether nephrostomy tube could be removed safely.

Abstract
Purpose: Available tools for the prediction of the prognosis of patients with upper tract urothelial carcinoma (UTUC) are unified. We determined whether a novel nomogram is effective in estimating the survival of patients with invasive UTUC. Methods: From January 2004 to December 2015, 4796 invasive UTUC patients in the Surveillance, Epidemiology and End Results database underwent radical nephroureterectomy (RNU) for invasive UTUC. The medical records of the patients were randomly (7:3) divided into the training and validation cohorts. The independent factors included in the nomogram were selected by multivariate analyses. The nomogram was developed based on the training cohort. Bootstrap validation was applied to validate the nomogram, whereas external validation was performed using the validation cohort. The accuracy and discrimination of the nomogram were assessed using concordance indices (C-indices) and calibration curves. Results: The multivariate Cox regression model identified that age, tumor stage, node stage, metastasis stage and grade were associated with survival. In the training set, the nomogram, which included the above factors, exhibited discrimination power superior to that of the 8th American Joint Committee on Cancer (AJCC) TNM classification (Harrell's C-index, 0.74 vs. 0.71; P < 0.001). The nomogram showed better probability of survival agreement with the C-index than the AJCC-TNM staging system in the bootstrap validation (0.74 vs. 0.70; P < 0.001) and validation set (Harrell's C-index, 0.77 vs. 0.73; P < 0.001). The validation revealed that this nomogram exhibited excellent discrimination and calibration capacities. Conclusion: An accurate novel nomogram that is superior to the current AJCC-TNM staging system was established for the prediction of CSS after RNU for invasive UTUC.

Abstract
Introduction: There are limited data regarding the effect of thulium laser (Tm:YAG) and holmium laser (Ho:YAG) on upper urinary tract. The aim of this study was to compare soft tissue effects of these two lasers at various settings, with a focus on incision depth (ID) and coagulation area (CA). Materials and Methods: An ex vivo experimental study was performed in a porcine model. The kidneys were dissected to expose the upper urinary tract and the block samples containing urothelium and renal parenchyma were prepared. The laser fiber, fixed on a robotic arm, perpendicular to the target tissue was used with a 100 W Ho:YAG and a 200 W Tm:YAG. Incisions were made with the laser tip in contact with the urothelium and in continuous movement at a constant speed of 2 mm/s over a length of 1.5 cm. Total energy varied from 5 to 30 W. Incision shape was classified as follows: saccular, triangular, tubular, and irregular. ID, vaporization area (VA), CA, and total laser area (TLA = VA + CA) were evaluated. Statistical analysis was performed using the SPSS V23 package, p-values <0.05 were considered statistically significant. Results: A total of 216 experiments were performed. Incision shapes were saccular (46%), triangular (38%), and irregular (16%) with the Ho:YAG, while they were tubular (89%) and irregular (11%) with the Tm:YAG. ID was significantly deeper with the Ho:YAG (p = 0.024), while CA and TLA were larger with the Tm:YAG (p < 0.001 and p < 0.005). Conclusion: ID was deeper with Ho:YAG, whereas CA and TLA were larger with the Tm:YAG. Considering surgical principles for endoscopic ablation of upper tract urothelial carcinoma, these results suggest that Tm:YAG may have a lower risk profile (less depth of incision) while also being more efficient at tissue destruction. Future in vivo studies are necessary to corroborate these findings.

Abstract
Introduction: Management of the distal ureter during laparoscopic nephroureterectomy (LNU) for upper tract urothelial carcinoma (UTUC) is controversial. The aim of this review was to determine whether this affects oncological outcomes. Methods: A literature review was conducted searching MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials in June 2019. Studies reporting outcomes of LNU in UTUC using either open, laparoscopic, or endoscopic approaches to excise the distal ureter were identified. All eligible studies underwent critical appraisal and were excluded if not of sufficient quality. Cumulative analysis of the results was performed. Results: Nine studies with a total of 383 patients (168 open, 159 laparoscopic, and 56 endoscopic excision of distal ureter) were eligible for inclusion. Study design and outcome reporting were variable between studies. Mean age of patients was comparable (67.7 years versus 65.0 years versus 66.6 years). Mean follow-up duration was comparable between open and laparoscopic groups (46.2 months versus 45.5 months) but reduced in the endoscopic group (33.4 months). The open group had a higher proportion of high grade/G3 tumors and pT2-4 tumors when compared to the laparoscopic and endoscopic groups (P < .001 and P = .002). The open group had a higher rate of intravesical recurrence and the laparoscopic group had a higher rate of distant metastases (P < .001). Conclusion: This review has identified differences in oncological outcomes between different techniques of managing the distal ureter in LNU for UTUC. However, the poor reporting of potentially confounding factors does not enable any one technique to be recommended as superior and requires further research.

Abstract
Objectives: To evaluate the diagnostic yield and concordance of upper tract urothelial carcinoma (UTUC) grading between ureterorenoscopic biopsies and surgical resections. Materials and Methods: The nationwide Dutch Pathology Registry (nationwide network and registry of histo- and cytopathology in the Netherlands [PALGA]) was searched for UTUC-positive renal units (RUs) with histopathology excerpts from ureterorenoscopic biopsies and surgical resections, matched for laterality and localization of the tumor, from 2011 until 2018. The positive predictive value (concordance) of the biopsy grade with regard to the final grade according to the World Health Organization (WHO) 2004 classification was calculated. Results: A total of 1002 UTUC-positive rental units were included, of which 776 UTUC-positive RUs were graded according to the WHO 2004 classification in the ureterorenoscopic biopsy, the localization-matched surgical resection, or in both. The diagnostic yield of biopsies for a classifying diagnosis was 89% with a sensitivity for UTUC of 84%. In case of UTUC, the diagnostic yield for biopsy-based grading and staging was 97% and 72%, respectively. The concordance of high-grade biopsies with regard to the final histopathology was 97% and 62% for low-grade biopsies. Upgrading to final high grade occurred in 33% of the low-grade biopsies. Downgrading to final low grade occurred in 2% of high-grade biopsies. Conclusions: This is the first study to portray the limitations of ureterorenoscopic biopsies for UTUC in a nationwide cohort. The diagnostic yield of ureterorenoscopic biopsies for a classifying diagnosis is suboptimal, but the diagnostic yield for grading according to the WHO 2004 classification is high. Yet, a worrisome amount of ureterorenoscopic biopsies are upgraded with regard to the surgical resection. Consequently, one-third of patients, who qualify for kidney-sparing treatment according to one of the criteria recommended for risk stratification, might be stratified incorrectly. These findings stress the importance of a timely and stringent ureterorenoscopic follow-up after kidney-sparing surgery and highlight the need for improvements in the diagnostic approach to optimize the risk stratification.

Abstract
BACKGROUND As a member of the Rho small guanosine triphosphatase family, ras-related C3 botulinum toxin substrate 1 (RAC1) interacts with various specific effectors, and p21-activated kinase 1 (PAK1), which has a role in both carcinogenesis and cellular invasion, binds to RAC1, after which activated PAK1 regulates cellular functions. There have been few reports about the simultaneous analysis of RAC1 and its downstream effector PAK1 in upper urinary tract urothelial carcinoma (UTUC). We assessed the expressions of both RAC1 and PAK1 and evaluated their association with clinicopathological parameters. METHODS Immunohistochemical studies of RAC1 or PAK1 were performed with specimens from 104 patients with N0M0 UTUC and cancer-free surgical margins. Correlation of the positive expression of RAC1 or PAK1 or both with clinicopathological parameters was evaluated. RESULTS A hazard model showed that the presence of mixed histologic features and moderate or strong positive expression of both RAC1 and PAK1 were independent factors for shortened disease-specific survival time (Ps = 0.041 and 0.016, respectively), and another hazard model revealed that only moderate or strong positive expression of both RAC1 and PAK1 was an independent factor for shortened recurrence-free survival time in the multivariate analysis (P = 0.036). Neither moderate or strong positive expression of RAC1 alone nor moderate or strong positive expression of PAK1 alone was an independent factor for a worse rate of disease-specific or recurrence-free survival in multivariate analysis. CONCLUSIONS Patients with N0M0 UTUC, cancer-free surgical margins and moderate or strong positive expression of both RAC1 and PAK1 should be carefully monitored after surgery.

Abstract
Introduction Unlike the established evidence to use chemotherapy for urothelial carcinoma of the bladder, presently there are insufficient data to inform a recommendation on upper urinary tract urothelial carcinoma treatment. The prognosis for patients with stage T4 and positive lymph nodes is poor; however, primary tumors in the renal pelvis are associated with favorable prognoses compared to those located in the ureter. Our study aimed at investigating the effectiveness of chemotherapy in patients with pT3N0M0 renal pelvic urothelial carcinomas (RPUC) who have relative favorable prognosis. Methods Patients with pT3N0M0 tumors who underwent radical nephroureterectomy combined with bladder cuff excision between 2005 and 2014 and registered in the Surveillance, Epidemiology, and End Results database were eligible for inclusion (n = 939). Baseline characteristics between the chemotherapy and observation groups were controlled for with inverse probability of treatment weighting (IPTW)‐adjusted analysis. Results After the IPTW‐adjusted analysis, the 5‐year IPTW‐adjusted rates of overall survival (OS) for the chemotherapy and observation groups were 53.1% and 44.9%, respectively. The IPTW‐adjusted Kaplan‐Meier curves suggested that chemotherapy was associated with increased OS compared with observation (P = .028). In the IPTW‐adjusted Cox proportional hazards regression model, chemotherapy was associated with favorable survival benefits compared with observation (hazard ratio [HR] 0.71, 95% CI 0.52‐0.92, P = .031), and this was maintained after bootstrapping (HR 0.72, 95% CI 0.49‐0.93). Chemotherapy had a protective effect on OS benefits, which were found in a majority of the results of the subgroup analysis and were consistent with the main results (all P‐interactions > 0.05). Conclusion Chemotherapy may provide significant OS benefits for patients with pT3N0M0 RPUC. The results of our study could strengthen the evidence for using adjuvant chemotherapy in this rare group of patients.

Abstract
Introduction Complex ureteral obstruction is a pathology that has always been a challenge for the urologist, especially in patients with high surgical risk or with a short life expectancy. Material and methods Between 2002 and 2017, 13 extra-anatomical bypasses were placed. A descriptive retrospective study was carried out. An analysis of the permeability time of the prosthesis was performed using Kaplan-Meyer curves. Demographic and etiological characteristics as well as early and late complications were analysed. Results Etiologies were benign in 39% (including 3 transplant recipients) and malignant in 69%. Permeability rates were 90.9% at each of 12, 24 and 48 months, respectively, and 75.8% at 60 months. There were no deaths in the early postoperative period, nor intraoperative complications. The most frequent complications were infections. Three of them were associated with bypass extrusion, which needed to be removed. A total of 5 prosthesis had to be removed. 40% of the patients did not present complications. Conclusions The extra-anatomical ureteral bypass is an alternative to permanent nephrostomy in the treatment of complex ureteral strictures. Their patency rates after long-term follow-up vary from 90% to 75% at 48 and 60 months, respectively. Their complication rates can be considered acceptable in the patients’ clinical contexts.

Abstract
INTRODUCTION Urothelial carcinoma is the second most common urological malignancy. Around 5-10% of tumors are found in the upper urinary tract, while almost 90-95% are in the bladder. METHODS Patients of our department diagnosed with upper urinary tract urothelial carcinoma (UTUC) during the period 2014-2018 were included. The frequency, selected therapeutic procedures and treatment results were analyzed. RESULTS In the last 5 years, 21 patients with UTUC were diagnosed and surgically treated at the Department of Urology, Regional Hospital Nachod. The main surgical approach was nephroureterectomy. Mortality was 28.6% due to the original tumor diagnosis. Urothelial carcinoma of the upper urinary tract was more common in men than in women in our patient group. CONCLUSION Unfortunately, urothelial carcinomas of the upper urinary tract are often dealt with only in locally advanced stages or when nodal or distant metastases are present, making any possible administration of adjuvant chemotherapy complicated as it fails to provide a sufficient effect. Therefore, radical nephroureterectomy remains the gold standard for more than a half of patients. Overall survival depends largely on the presence of distant metastases. The pT category is the major influencing parameter for a relapse.

Abstract
Purpose Elevated plasma D-dimer levels were thought to be associated with decreasing survival in various cancers. The relationship between plasma D-dimer levels and clinicopathology and the optimal D-dimer cutoff as a prognostic predictor has not been determined in patients with upper tract urothelial carcinoma (UTUC). We aimed to investigate the prognostic value of preoperative plasma D-dimer levels as a predictor of patient outcomes in UTUC following radical nephroureterectomy. Patients and Methods We retrospectively reviewed data for 232 patients. The D-dimer cutoff value was set at 0.36 mg/L, and we used the Kaplan-Meier method and Cox's proportional hazards regression models to analyze the association between D-dimer levels and oncological outcomes. Multivariate Cox regression was used to develop a nomogram, which we evaluated for accuracy using a receiver operating characteristic curve, calibration plot, and decision curve analysis. Results Plasma D-dimer levels ≥0.36 mg/L were significantly associated with advanced tumor status regarding size, location, hydronephrosis, tumor grade, lymph node involvement, grade, and stage (all p < 0.05). The Kaplan-Meier analysis showed that plasma D-dimer levels ≥0.36 mg/L predicted worse oncological outcomes vs levels <0.36 mg/L (all p < 0.001). Univariate and multivariate analyses showed that elevated preoperative plasma D-dimer level was an independent predictor of recurrence-free survival (hazard ratio (HR): 1.67, 95% confidence interval (CI): 1.07-2.63; p = 0.025), cancer-specific survival (HR: 2.34, 95% CI: 1.30-4.19; p = 0.004), and overall survival (HR: 1.98, 95% CI: 1.18-3.34; p = 0.010). We also developed a nomogram predicting 3- and 5-year overall survival probability. Conclusion D-dimer levels may be a useful prognostic predictor of survival and improve risk stratification and precisely individualize treatment for patients with UTUC.

Abstract
The aim of this study was to develop a less invasive and accurate diagnostic system for upper urinary tract urothelial carcinoma (UTUC) based on genome-wide DNA methylation profiling. Genome-wide DNA methylation screening was performed using the Infinium HumanMethylation450 BeadChip, and DNA methylation quantification was verified using pyrosequencing. We analysed 26 samples of normal control urothelial tissue (C), an initial cohort of 62 samples (31 samples of non-cancerous urothelium [N] from UTUC patients and 31 samples of the corresponding UTUCs), a validation cohort of 82 samples (41 N and 41 UTUC samples), and 14 samples of urinary bladder urothelial carcinoma (BUC). In the initial cohort, we identified 2,448 CpG sites showing significant differences in DNA methylation levels between both C and UTUC and N and UTUC, but not showing differences between C and N. Among these CpG sites, 10 were located within CpG islands or their shores and shelves included in genomic domains where DNA methylation levels are stably controlled, allowing discrimination of UTUC even from BUC. Receiver operating characteristic curve analysis for discrimination of UTUC from N in these 10 CpG and neighbouring sites (37 diagnostic panels in total) yielded area under the curve values of 0.959-1.000, with a sensitivity and specificity of 86.6-100% and 93.5-100%, respectively. The diagnostic impact was successfully confirmed in the validation cohort. Our criteria were useful for diagnosis of UTUC, regardless of its clinicopathological features. Application of our criteria to voided urine samples will ultimately allow non-invasive DNA methylation diagnosis of UTUC.

Abstract
Objective To compare the efficacy and safety of miniature semi-rigid ureteroscopy (URS) with holmium (Ho)-yttrium-aluminium-garnet (YAG) laser lithotripsy vs shockwave lithotripsy (SWL) for treating upper urinary tract (UUT) calculi >1 cm in children. Patients and methods Children with unilateral single UUT ureteric stones of >1 cm were prospectively enrolled in this study. Patients were randomly divided into two groups: Group 1, treated with SWL; and Group 2, treated with URS (6/7.5 F) and laser lithotripsy. The patients’ characteristics, stones demographics, operative time, adjunctive procedures, stone-free rate (SFR), re-treatment rate, and complications were statistically analysed and compared. Success was defined as stone-free status (no stone residual of ≥0.3 cm) at 1 month from the initial treatment without any auxiliary procedures. Results In all, 68 patients with UUT stones met our inclusion criteria. There were no significant differences between the two groups for patient or stone demographics. In Group 1, the SFR was 26/34 (76.4%) and in Group 2 it was 33/34 (97.1%) (P = 0.03). A total of 12 auxiliary procedures in Group 1 and two in Group 2 were needed to reach a 100% SFR (P = 0.014). There were no significant differences between the two groups for operative times, adjunctive procedures, number of complicated cases or complications of Grade ≥III (P = 0.65, P = 0.23, P = 0.77, and P = 0.62, respectively). Conclusion Miniature semi-rigid URS with Ho-YAG laser lithotripsy for UUT ureteric stones of >1 cm in children was more effective than SWL in terms of SFR and re-treatment rate, with no significant difference in the rate or grade of complications. Abbreviations EQ: efficiency quotient; KUB: plain abdominal radiograph of the kidneys, ureters and bladder; RCT: randomised controlled trial; SFR: stone-free rate; SWL: shockwave lithotripsy; URS: ureteroscopy; US: ultrasonography/ultrasound; URS: ureteroscopy; UUT: upper urinary tract; YAG: yttrium-aluminium-garnet

Abstract
PURPOSE The current study evaluated the prevalence of urologic disease among patients with hematuria referred for computerized tomography (CT) urography to determine which patients require investigation with CT urography. METHODS We retrospectively reviewed radiology reports of 1046 CT urograms performed for the indication of microscopic (43.7%) or gross hematuria (56.3%). Urological findings were categorized as negative, benign, or suspicious (pathologically confirmed) for malignancy. RESULTS Of 1046 CT urograms performed, 53.5% were negative, 36.4% were benign, and 10% were suspicious for malignancy. The most common benign finding was urolithiasis (22.3%). Overall, urinary tract malignancies were present in 3.6% of patients, and the rate was significantly higher (P < .001) for gross (5.8%) than microscopic hematuria (0.9%). CT urography identified 0.6% patients with upper urinary tract malignancies; the malignancy rate was significantly higher (P = .038) for gross (1%) than microscopic hematuria (0%), and no significant sex (P = 1.00; male = 0.6%, female = 0.6%) or age (P = .600; < 50 years = 0%, ≥ 50 years = 0.7%) differences were observed. Logistic regression revealed that being male was associated with gross hematuria (odds ratio [OR] = 2.92), and that both age and gross hematuria (ORs = 1.06 and 5.13, respectively) were associated with malignancy. CONCLUSIONS CT urography found no upper urinary tract malignancies in 99.4% of patients presenting with hematuria, including all patients with microscopic hematuria and those with gross hematuria <50 years old. Investigating these subgroups with CT urography may be unnecessary and result in increased patient morbidity and health-care costs.

Abstract
The present study investigated the use of retrograde flexible ureteroscopy (RFU) in the discrimination of the etiology of hematuria that originates from the upper urinary tract (UUT). The present study collected retrospective data for patients who presented with hematuria and cystoscopy-detected bleeding from the UUT between June 2006 and August 2018 in Ningbo First Hospital. All patients accepted RFU to determine the etiology of hematuria. Data regarding imaging examinations, surgery, pathology and complications were also collected and analyzed. In total, 65 patients (males, 38; females, 27) with a mean age of 63 years underwent RFU to determine the etiology of hematuria originating from the UUT. Using RFU, UUT tumors were found in 29 cases. Stones, polyps and atypical hyperplasia were found in two cases, and a definite diagnosis was not found in three cases. There were 17 cases without obvious abnormalities and nine cases were unable to undergo RFU due to ureteral stenosis. In patients who could not be diagnosed by imaging examination, 34.4% (11/32) were diagnosed with urothelial carcinoma by RFU, and these results were also confirmed by postoperative pathology. In the present study, no patient had severe complications after RFU. The present results suggested RFU may be used as a sensitive method to diagnose UUT tumors (78.4%; 29/37) and has strong specificity. RFU could be performed as a routine examination for patients with hematuria from the UUT.

Abstract
BACKGROUND Available guidelines on the management of upper tract urothelial carcinoma (UTUC) are restricted due to the lack of strong evidence-based recommendations. Adequate, well-powered randomized trials are missing due to the rarity of the disease. To overcome this problem, we need alternative study designs to provide generalizable data. OBJECTIVE The primary aim of this registry is to provide a real-world overview on patterns of presentation and management of UTUC. Secondary objectives include comparison of outcomes of different treatments and tumor stages and evaluation of compliance with the current European Association of Urology recommendations for UTUC. METHODS For this observational, international, multicenter, cohort study, clinical data of consecutive patients suspected of having UTUC, irrespective of type of management, will be prospectively collected up to 5 years after inclusion. Data on the patterns of presentation, diagnostics, and treatment as well as short-, mid-, and long-term oncological and functional outcomes will be analyzed. Possible associations between variables, basal characteristics, and outcomes will be tested by multivariable analyses. The methodology will address potential sources of bias and confounders. RESULTS The registry was initiated in November 2014 after obtaining institutional review board approval. Data collection started in December 2014. At the time of submission of this manuscript, 2451 patients from 125 centers from 37 countries were included. Inclusion of patients will be closed 5 years after initiation of the registry. Quality checks will be performed centrally with continuous communication and feedback with the centers to ensure accuracy. The first results are expected in the first trimester of 2020. CONCLUSIONS This large observational prospective cohort will generate landmark "real-world" data and hypotheses for further studies. We expect these data to optimize the management of UTUC, provide insights on harms and benefits of treatment, and serve as quality control.

Abstract
INTRODUCTION The treatment standard for high-risk upper urinary tract urothelial carcinoma (UUTUC) is radical nephroureterectomy. However, some patients may be unfit or unwilling, and in such patients the available alternatives are suboptimal. Therapies targeting the programmed death (PD) pathway have shown promise in urothelial carcinom (UC). We designed the current study to determine the safety and efficacy of administering MK-3475 (a monoclonal antibody targeting interaction between PD-1 and its ligand) in combination with bacillus Calmette-Guerin (BCG) in high-risk non-muscle invasive UUTUC patients. METHODS This represents a single-centre phase-II efficacy study of MK-3475 therapy in combination with BCG for subjects, 18 years of age or older, with pathologically documented non-muscle invasive high-risk UUTUC unfit or unwilling to be treated with radical nephroureterectomy. Twenty subjects will be enrolled; patients will receive treatment with 200 mg of MK-3475 every 21 days, starting 2 weeks from the initial endoscopic resection and continuing for 6 weeks after the final dose of BCG. The primary objective is to determine the safety and efficacy of administering MK-3475 at a fixed dose of 200 mg every 3 weeks in conjunction with intrapelvic BCG. Secondary objectives include 19 week and the 3, 12 and 24-month post-treatment completion complete response and progression-free rate assessments. ETHICS AND DISSEMINATION The study has been approved by the Institutional Review Board of the Henry Ford Hospital. The results of this study will be published in a peer-reviewed journal and presented at a scientific conference. TRIAL REGISTRATION NUMBER NCT03345134.

Abstract
Upper urinary surgery is an important area of urology surgery. Open surgery used to be the gold standard of upper urinary surgery. With the development of medical techniques, minimal invasive surgeries including laparoscopic and robot assisted-laparoscopic surgery have gradually replaced the open surgery. Because of the complexity and diversity of upper urinary diseases, surgeries sometimes are difficult, and minimal invasive surgeries require higher surgical abilities of urologists than open surgeries. In recent years, depending on our surgical experience and international reports, our team from three Chinese medical centers summarizes techniques of upper urinary minimal invasive surgeries. For malignant diseases, such as renal and ureteral carcinomas, it's important to totally remove the tumor first, and then to avoid the surgical injuries. We summarize surgical experience of retroperitoneal laparoscopic partial nephrectomy for moderately complex renal hilar tumors. Our team modified minimal invasive techniques for some complex tumors, including ring suture technique for renal hilar tumors, internal suspension technique for renal ventral tumors, and combination retroperitoneal laparoscopic surgery with mini-flank incision for complex renal tumors. While for begin diseases, urologists should focus on the resections and surgical injuries at the same time. We have reported the novel technique of laparoscopic aspiration for central renal angiomyolipoma, making the surgery simple and available. For reconstruction surgeries, operations should be based on several principals. We generalize it as "4TB principals", which include "tension-free", "water-tight", "thin suture", "no touch of the key area" and "protecting the blood supply". Depending on the localization, length, and etiology of the strictures, different techniques are required. Our team summarize the pyeloplasty, ureteral reimplantation and ileal ureter replacement based on our surgical experience. For infant upper urinary surgeries, our team has made invasive surgeries that can be used in complex diseases, such as duplex kidney. Based on years of surgical techniques, our modified surgeries achieve a better subjective cosmetic result than the traditional surgeries. In the future, the standardized, practical, simple and individual minimal invasive surgical technique will become the main direction in the future researches.

Abstract
OBJECTIVE To compare the efficacy and safety of complete transperitoneal laparoscopic nephroureterectomy (CTNU) and traditional retroperitoneoscopic nehroureterectomy (TRNU) for the management of upper urinary tract urothelial carcinoma(UTUC). METHODS We retrospectively collected the clinical data of UTUC patients who underwent CTNU or TRNU surgery from January 2011 to December 2018 in Peking University First Hospital and Fujian Provincial Hospital, and compared the clinical characteristics, perioperative parameters, and follow-up results between the CTNU and TRNU surgeries. RESULTS Finally, a total of 266 cases were included, with 94 cases in the CTNU group and 172 cases in the TRNU group. The proportion of left side lesions was bigger in TRNU group when compared with CTNU group (P<0.05). No significant differences were observed in clinical characteristics, such as age, gender, body mass index (BMI), American society of anesthesiologists score (ASA score) and tumor laterality. All surgery procedures were completed. The vascular resparing was performed by reason that left arteria renalis was injured accidently during surgical operation in one case of TRNU group. No serious complications were observed in both CTNU and TRNU groups. In CTNU group, operating time was (202.9±76.7) min, estimated blood loss was (68.4±73.3) mL, drainage duration was (3.9±1.5) d, drainage volume was (181.7±251.5) mL, and postoperative hospital stay was (7.8±4.1) d. In TRNU group, operating time was (203.5±68.7) min, estimated blood loss was (130.2±252.1) mL, drainage duration was (4.3 ±1.6) d, drainage volume was (179.1±167.5) mL, and postoperative hospital stay was (8.2±3.7) d. The estimated blood loss in CTNU group was significantly less than that in TRNU group (P=0.005).The median follow-up time was 39 months (range: 1-88 months). The 5-year overall survival rate (OS), cancer specific survival rate (CSS), intra-vesical recurrence free survival rate (IvRFS), disease free survival rate (DFS) of CTNU group was 75.6%, 86.9%, 73.8%, 57.5%, respectively. The OS, CSS, IvRFS and DFS of TRNU group was 66.3%, 83.5%, 75.9%, 58.6%, respectively.No significant differences were observed in the OS, CSS, IvRFS and DFS between the CTNU and TRNU groups. CONCLUSION CTNU technique is a safe and effective surgical option, and further prospective randomized controlled trial is needed for further evaluation.

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
Objective This study aimed to compare the effect of percutaneous nephrolithotomy (PCNL)
under local infiltration anesthesia (PCNL-LIA) and general anesthesia
(PCNL-GA) to treat upper urinary tract calculi on clinical application
values. Methods Patients were randomly divided into the PCNL-LIA (16 patients) and PCNL-GA
(20 patients) groups. Data on safety, cost, complications, rate of residual
calculi, and prognosis were compared. Results The mean operation time in the PCNL-LIA group was less than that in PCNL-GA
group (100±7.7 versus 120±9.0 minutes). The mean length of hospital stay in
the PCNL-LIA group was shorter than that in the PCNL-GA group (6.9±0.5
versus 10.5±1.2 days). The rate of patients who required blood transfusion
because of blood loss during or after surgery was less in the PCNL-LIN group
than in the PCNL-GA group (13% versus 40%). The intervention rate in the
PCNL-GA group was higher than that in the PCNL-LIA group. Visual analogue
pain scale assessment showed that the PCNL-LIA group showed slightly more
pain than the PCNL-GA group. Conclusion PCNL-LIA is safer, faster, and more convenient, and it also provides the
benefits of a lower rate of blood loss and complications, lower cost, faster
recovery, and shorter hospital stay compared with PCNL-GA.
