OBJECTIVES: To compare functional outcomes of warm ischemia RPN (wRPN) to cold ischemia RPN (cRPN) in "at risk" patients. MATERIALS AND METHODS: Retrospective review of Institutional database queried for all patients who underwent cRPN/wRPN (January 2007 - December 2016). For the study purpose, patients with solitary kidney and/or history of partial nephrectomy and/or multiple tumors and/or preoperative eGFR <60 ml/min were extracted. To reduce inherent biases, groups were matched on key variables related to renal function via a greedy matching algorithm with no replacement...

We retrospectively analyzed the factors related to postoperative cardiovascular (CV) events in patients undergoing partial nephrectomy (PN) or radical nephrectomy (RN) for clinical T1 renal cell carcinoma (RCC). We identified 570 patients who underwent PN or RN for T1 renal cell carcinoma between January 1998 and December 2009 at our institution and related hospitals. We determined the cumulative incidence rate of CV events and overall survival (OS) using Kaplan-Meier survival curves with a log-rank test, and we evaluated the risk for an increase in CV events and OS using Cox proportional hazard regression...

OBJECTIVES: To develop a predictive nomogram for chronic kidney disease-free survival probability in the long term after partial nephrectomy. METHODS: A retrospective analysis was carried out of 698 patients with T1 renal tumors undergoing partial nephrectomy at a tertiary academic institution. A multivariable Cox regression analysis was carried out based on parameters proven to have an impact on postoperative renal function. Patients with incomplete data, <12 months follow up and preoperative chronic kidney disease stage III or greater were excluded...

BACKGROUND: Nephroblastomatosis is an uncommon pathologic process characterized by the presence of persistent embryonic nephrogenic rests. Progression to Wilms tumour occurs in an estimated 35% of patients. Cure rates are based on histologic findings and disease stage and have improved from 10% in the 1920s to over 90% today. CASE PRESENTATION: We report a case of a 9-month-old female presenting with a 2-month history of abdominal distension. Ultrasonographic and computed tomographic assessments demonstrated features consistent with bilateral, diffuse, hyperplastic perilobar nephroblastomatosis (DHPLNB) for which she underwent chemotherapy...

PURPOSE: While surgical approach has recently been associated with positive surgical margin (PSM) following partial nephrectomy (PN) for small (<4 cm) renal masses, its impact on margin status for large (>4 cm) masses is unclear. We sought to evaluate the relationship between margin and surgical approach in patients undergoing PN for large renal masses. MATERIALS AND METHODS: Using the National Cancer Database (NCDB), we identified patients undergoing PN for pathological T1b and T2a renal cell carcinoma (RCC) diagnosed from 2010 to 2013...

Chromosome 3p deletion is a well-established genetic aberration in clear cell renal cell carcinoma (RCC). We aimed to evaluate the clinical utility of 3p fluorescence in situ hybridization (FISH) on formalin-fixed paraffin-embedded tissue in surgical pathology specimens. 3p:3q <0.8 was established as the cut-off for 3p loss. The 2015 Medicare allowable billing rates were used to estimate the cost. Over 2.5 years (2013 to 2015), 3p FISH was performed on 18 cases per year. Among tested cases, 70% (30/43) were nephrectomies and 30% (14/43) metastases...

Background Comparable oncological outcomes have been seen after surgical nephrectomy and thermal ablation of renal tumors recently. However, periprocedural outcome needs to be assessed for aiding treatment decision. Purpose To compare efficacy rates and periprocedural outcome (technical success, session time, hospitalization time, and complications) after renal tumor treatment with laparoscopic partial nephrectomy (LPN) or radiofrequency ablation (RFA). Material and Methods The initial experience with 49 (treated with LPN) and 84 (treated with RFA) consecutive patients for a single renal tumor (diameter ≤ 5 cm, limited to the kidney) during 2007-2014 was evaluated...

BACKGROUND: Safety-net hospitals (SNHs) care for more patients of low socioeconomic status (SES) than non-SNHs and are disproportionately punished under SES-naive Medicare readmission risk-adjustment models. This study was designed to develop a risk-adjustment framework that incorporates SES and to assess the impact on readmission rates. METHODS: California Office of Statewide Health Planning and Development data from 2007 to 2011 were used to identify patients undergoing radical cystectomy (RC) for bladder cancer (n = 3771) or partial nephrectomy (PN; n = 5556) or radical nephrectomy (RN; n = 13,136) for kidney cancer...

BACKGROUND: The preoperative neutrophil-to-lymphocyte ratio (NLR), C-reactive protein/albumin ratio (CRP/Alb ratio) and platelet-to-lymphocyte ratio (PLR) have been demonstrated to predict the clinical outcome of various human cancer, including renal cell carcinoma(RCC). The aim of our study was to explore the prognostic values of these ratios in patients with Xp11.2 translocation/TFE3 gene fusions renal cell carcinoma (Xp11.2 tRCC). METHODS: A retrospective multicentre study was performed in 82 Xp11...

BACKGROUND: Xanthogranulomatous pyelonephritis (XGP) is an uncommon infectious disease of the kidney known to mimic other renal maladies. A rare presentation of this uncommon disease is spontaneous renal hemorrhage (SRH). CASE PRESENTATION: We report a case of XGP in a 58 year old woman who presented with abdominal pain, hematuria, and radiating left flank pain. CT scan was felt to be consistent with perirenal hemorrhage abutting a fat-containing renal mass. The patient was eventually taken to surgery for left partial nephrectomy...

A 61-year-old male was admitted from the outpatient setting for treatment of severe hyperglycemia. Five months earlier, his hemoglobin A1c had been 5 mmol/mol. At presentation, hemoglobin A1c was 11.3 mmol/mol and he required insulin therapy at discharge. Later magnetic resonance imaging (MRI) identified bilateral renal masses, previously seen on ultrasound during workup for chronic kidney disease, as being suspicious for renal cell carcinoma (RCC). He underwent partial nephrectomy and cryoablation with pathology showing papillary type RCC...
