Fluorescence in situ hybridization in 1 mL of selective urine for the detection of upper tract urothelial carcinoma: a feasibility study.

Med Oncol 2018 Nov 29;36(1):10. Epub 2018 Nov 29.

Department of Urology, Amsterdam University Medical Centers, University of Amsterdam, Meibergdreef 9 G4-223, 1105AZ, Amsterdam, The Netherlands.

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. Read More

Protease-activated receptor-1 contributes to renal injury and interstitial fibrosis during chronic obstructive nephropathy.

J Cell Mol Med 2018 Nov 28. Epub 2018 Nov 28.

Center for Experimental and Molecular Medicine, Academic Medical Center Amsterdam, Amsterdam, The Netherlands.

End-stage renal disease, the final stage of all chronic kidney disorders, is associated with renal fibrosis and inevitably leads to renal failure and death. Transition of tubular epithelial cells (TECs) into mesenchymal fibroblasts constitutes a proposed mechanism underlying the progression of renal fibrosis and here we assessed whether protease-activated receptor (PAR)-1, which recently emerged as an inducer of epithelial-to-mesenchymal transition (EMT), aggravates renal fibrosis. We show that PAR-1 activation on TECs reduces the expression of epithelial markers and simultaneously induces mesenchymal marker expression reminiscent of EMT. Read More

Quantitative Urinary Proteome Reveals Potential Biomarkers for Ureteropelvic Junction Obstruction.

Proteomics Clin Appl 2018 Nov 24:e1800101. Epub 2018 Nov 24.

Department of Pediatric Urology, Xinhua Hospital Affiliated to Shanghai Jiao Tong University School of Medicine, 200092, Shanghai, China.

Purpose: Ureteropelvic junction obstruction (UPJO) is a common obstructive disease. To investigate useful urinary biomarkers in UPJO children, the urinary proteome in UPJO infants is analyzed and it is compared with normal controls.

Experimental Design: A tandem mass tag (TMT)-based quantitative proteomics study is performed to analyze the proteome of bladder urine (BU) and pelvis urine (PU) from unilateral UPJO infants with differential renal function less than 40% and they are compared with normal control urine (CON).

Diagnosis and management of urinary extravasation after high-grade renal trauma.

Nat Rev Urol 2018 Nov 23. Epub 2018 Nov 23.

Division of Urology, Department of Surgery, University of Utah, Salt Lake City, UT, USA.

Renal trauma research has historically focused on parenchymal injuries and the risk of bleeding. However, much less is known about the diagnosis and optimal management of urinary extravasation, which complicates ~30% of high-grade renal injuries. Immediate or delayed ureteral stenting is the most common procedure used to treat collecting system injuries when intervention is needed. Read More

Initial collection of an inadequate 24-hour urine sample in children does not predict subsequent inadequate collections.

J Pediatr Urol 2018 Oct 28. Epub 2018 Oct 28.

Division of Nephrology, Department of Pediatrics, Indiana University School of Medicine, United States.

Introduction: Approximately half of adult stone formers submit specimens that are either under or over collections as determined by 24-h creatinine/kg. Previously identified predictors of inadequate collection in adults include female sex, older age, higher body mass index (BMI), vitamin D supplementation, and weekday collection.

Objective: The objective of this study is to determine risk factors for inadequate 24-h urinary specimen collection in the pediatric population. Read More

Tumors of Renal Collecting Systems, Renal Pelvis, and Ureters: Role of MR Imaging and MR Urography Versus Computed Tomography Urography.

Magn Reson Imaging Clin N Am 2019 Feb;27(1):15-32

Abdominal Imaging Division, UT Southwestern University Hospitals, 5323 Harry Hines Boulevard, Dallas, TX 75390-8827, USA.

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. Read More
