Kidney-sparing surgery of upper tract urothelial carcinoma (UTUC) requires a stringent follow-up with frequent ureteroscopies. Triage testing could reduce the number of follow-up ureteroscopies and hence minimize the invasiveness of follow-up. The use of urine-based markers for triage seems appealing but should be feasible with selective urine from outpatient cystoscopy to maximize the reduction of invasiveness. In this study, the feasibility of UroVysion® fluorescence in situ hybridization (FISH) for the detection of UTUC in 1 mL of selective urine is investigated...

BACKGROUND: Pretreatment controlling nutritional status (CONUT) score is a novel index which was used to predict outcomes in cancer patients. We aim to explore the prognostic significance of CONUT score in patients with upper tract urothelial carcinoma (UTUC) after radical nephroureterectomy (RNU). PATIENTS AND METHODS: A total of 662 UTUC patients between 2004 and 2016 were retrospectively analyzed. Patients were categorized into three groups based on CONUT score (Normal: 0-1; Light: 2-4; Moderate/severe: 5-12)...

INTRODUCTION: We aimed to compare oncological outcomes by surgery type (segmental ureterectomy [SU] vs. radical nephroureterectomy [RNU]) in a large cohort of patients with upper tract urothelial carcinoma (UTUC) of the distal ureter. METHODS: We performed a retrospective analysis of 219 patients with UTUC of the distal ureter among 931 patients with UTUC who underwent SU and RNU. Clinicopathological outcomes were evaluated. Cancer-specific survival (CSS), overall survival (OS), local recurrence-free survival (RFS), intravesical recurrence-free survival (IVRFS), contralateral recurrence-free survival, and distal metastasis-free survival were assessed by the Kaplan-Meier method and Cox regression, estimating hazard ratios (HR) and 95% confidence intervals (CIs)...

Activating mutations in the promoter of the telomerase reverse transcriptase (TERT) gene are the most common genetic alterations in urothelial carcinoma (UC) of the bladder and upper urinary tract. While the cadherin 1 (CDH1) gene is commonly mutated in the clinically aggressive plasmacytoid variant of urothelial carcinoma (PUC), little is known about their TERT promoter mutation status. A retrospective search of our archives for PUC and UC with plasmacytoid and/or signet ring cell features (2007-2014) was performed...

Cystatin-C (Cys-C) has been reported as a valuable prognostic biomarker in various malignancies. However, its effect on upper tract urothelial carcinoma (UTUC) patients has not been investigated before. Thus, to explore the impact of Cys-C on survival outcomes in patients undergoing radical nephroureterectomy (RNU), a total of 538 patients with UTUC who underwent RNU between 2005 and 2014 in our center (West China Hospital, Chengdu, China) were included in this study. Kaplan-Meier method and Cox regression analyses were performed to assess the relationship between Cys-C and survival outcomes using SPSS version 22...

Segmental ureterectomy (SU) represents a promising alternative for the treatment of upper tract urothelial carcinomas (UTUCs) as it is a less invasive procedure and guarantees the preservation of renal units. The present study evaluated oncological outcomes and renal functions following SU when compared with radical nephroureterectomy (RNU). A total of 26 patients with UTUCs who underwent SU (n=12) or RNU (n=14) were retrospectively evaluated. SU was performed in patients with clinically unifocal disease. In the SU group, the following surgeries were carried out: 7 direct ureterocystoneostomy, 1 reimplantation on psoas hitch bladder, 1 reimplantation on Boari flap bladder, 2 ureteral end-to-end anastomosis and 1 subtotal ureterectomy...

Imaging techniques of upper tract urothelial carcinoma (UTUC) are presently limited. Upconversion particles (UCPs) could be used to target tumors for imaging. The present study aimed to assess the value of a nano-UCP as a diagnostic probe for deep tumor tissue, including UTUC. Polymer-coated water-soluble UCPs were synthesized. The pH Low Insertion Peptide (pHLIP) polypeptide was synthesized using the solid phase method. The silane shell surface was modified to present amino or carboxyl groups. Succinimidyl 4-(N-maleimidomethyl)cyclohexane-1-carboxylate was used for the coupling of the polypeptide to the UCPs...

Urothelial carcinoma in the upper tract is rare and often discussed separately. Many established risk factors were identified for the disease, including genetic and external risk factors. Radiographic survey, endoscopic examination and urine cytology remained the most important diagnostic modalities. In localized upper tract urothelial carcinomas, radical nephroureterectomy with bladder cuff excision are the gold standard for large, high-grade and suspected invasive tumors of the renal pelvis and proximal ureter, whereas kidney-sparing surgeries should be considered in patients with low-risk disease...

Non-clear cell renal cell carcinomas (RCCs) account for up to 25% of kidney cancers and encompass distinct diseases with distinct pathologic features, different molecular alterations, and various patterns of response to systemic therapies. Recent advances in molecular biology and large collaborative efforts helped to better define the oncogenic mechanisms at play in papillary, chromophobe, collecting duct, medullary, translocation, and sarcomatoid RCCs. Papillary RCCs are divided into several subsets of tumors characterized by distinct gene expression profiles, chromatin remodeling genes, cell cycle changes, and alterations of the MET pathway...

AIMS: Preventing kidney stone recurrence relies on detecting and modifying urine chemistry abnormalities. The assumption is that an abnormality is due to a global metabolic defect present in both kidneys. However, we hypothesize that clinically significant unilateral defects may exist. We aimed to identify these patients by sampling urine from each renal unit. MATERIALS AND METHODS: Adults undergoing retrograde upper urinary tract surgery were eligible for inclusion...

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...
