Immunotherapy targeting the programmed death-1 (PD-1) receptor/PD-1 ligand (PD-L1) pathway has shown promising results in several malignancies. However, the prognostic significance of PD-L1 expression remains unknown in patients with upper tract urothelial carcinoma (UTUC). This study aimed to evaluate PD-L1 expression and its association with clinicopathological characteristics and oncological outcomes in UTUC patients. PD-L1 expression on tumor cells and tumor-infiltrating mononuclear cells (TIMCs), and E-cadherin and N-cadherin expression on tumor cells were assessed by immunohistochemistry in a cohort of 162 patients with UTUC...

PURPOSE: Chronic kidney disease may adversely affect survival following nephrectomy. Proteinuria is increasingly used as a marker for kidney disease. However, the relationship between preoperative proteinuria and survival following nephrectomy remains incompletely characterized. We sought to evaluate the association of preoperative proteinuria with overall and cancer-specific survival using our institutional nephrectomy registry. MATERIALS AND METHODS: We identified 1,846 patients with localized clear cell renal cell carcinoma treated with curative intent (radical or partial nephrectomy) between 1995 and 2010...

BACKGROUND: We explore the association between short- and long- term adverse outcomes following coronary artery bypass grafting (CABG) and the degree of preoperative renal dysfunction classified on glomerular fraction estimated with Chronic Kidney Disease-Epidemiology Collaboration equation (eGFRCKD-EPI). We also try to identify cut-off values of eGFRCKD-EPI able to predict post-CABG unfavorable events and assess whether a reclassification with new thresholds is necessary. METHODS: One-thousand-one-hundred-eighty-six consecutive patients undergoing CABG between 2005 and 2014 were categorized in 4 groups according to the eGFRCKD-EPI: Group 1 (≥60ml/min/1...

BACKGROUND: Cardiac surgery-associated acute kidney injury (CSA-AKI) is a common complication and is associated with the poorest outcomes. Therefore, early prediction of CSA-AKI remains a major issue. Severity scores such as the STS score could estimate the risk of AKI preoperatively. The main objective of this study was to evaluate the risk factors of on-pump CSA-AKI and to assess the performance of the STS score in order to predict CSA-AKI. PATIENTS: We identified 252 patients with on-pump cardiac surgery, and the STS score was defined retrospectively...

Living kidney donor evaluation commonly includes nuclear renography to assess split kidney function and computed tomography (CT) scan to evaluate anatomy. To streamline donor workup and minimize exposure to radioisotopes, we sought to assess the feasibility of using proportional kidney volume from CT volumetry in lieu of nuclear renography. We examined the correlation between techniques and assessed their ability to predict residual postoperative kidney function following live donor nephrectomy. In a cohort of 224 live kidney donors, we compared proportional kidney volume derived by CT volumetry with split kidney function derived from nuclear renography and found only modest correlation (left kidney R(2) =26...
