BACKGROUND: Current staging paradigms from the American Joint Committee on Cancer (AJCC) staging system for upper urinary tract carcinomas treat locoregionally advanced (T4 and N+) and metastatic (M1) patients as a single entity (stage IV). The current study proposes a modification of the AJCC staging system where these 2 entities are separated. METHODS: The Surveillance, Epidemiology, and End Results (SEER) database (2004-2014) was accessed through SEER*Stat program...

The aim of this study was to develop a new methodology that is suitable for DNA methylation diagnostics and to demonstrate its clinical applicability. We developed a new anion-exchange column for high-performance liquid chromatography (HPLC) with electrostatic and hydrophobic properties. Both cytosine and thymine, corresponding to methylated and unmethylated cytosine after bisulfite modification, respectively, are captured by electrostatic interaction and then discriminated from each other by their hydrophobic interactions...

Minimal invasive endoscopic treatment for upper urinary tract urothelial carcinoma (UUT-UC) is advocated in patients with low-risk disease and limited tumor volume. Diagnostic ureterorenoscopy combined with biopsy is the diagnostic standard. This study aims to evaluate two alternative diagnostic techniques for UUT-UC: optical coherence tomography (OCT) and endoluminal ultrasound (ELUS). Following nephroureterectomy, OCT, ELUS, and computed tomography (CT) were performed of the complete nephroureterectomy specimen...

Introduction: Upper Tract Urothelial Carcinoma (UTUC) is a rare disease with few prognostic determinants. We sought to evaluate the impact of tumor size and location on patient survival following nephroureterectomy for UTUC. Materials and Methods: Data on 8284 patients treated with radical nephroureterectomy for UTUC in the United States between 1998 and 2011 were analyzed from the National Cancer Data Base. Univariable survivorship curves were generated based on pT stage, pN stage, grade, tumor size, and tumor site (renal pelvis vs...

OBJECTIVE: Previous studies have suggested a higher incidence of urologic malignancies in end-stage renal disease (ESRD) patients. However, incidence trends of urologic malignancies in ESRD patients remain unclear. The study's aims were 1) to investigate the pooled incidence/incidence trends and 2) to assess the risk of urologic malignancies in ESRD patients. METHODS: A literature search was conducted using MEDLINE, EMBASE and Cochrane Database from inception through April 2017...

Transitional cell carcinoma (TCC) arising from renal pelvis rarely gives rise to cutaneous metastasis. Due to the insufficient literature, the exact incidence is not known till date. Moreover, the diagnosis is confirmed on histopathological examination with the aid of immunohistochemistry wherever needed. We are presenting a case of a 70-year-old female with metastatic TCC from the renal pelvis to the abdominal skin, which was diagnosed on cytology alone along with the cell block preparation. We also highlight the important cytomorphological and immunohistochemical features noted, which need to be known to avoid any diagnostic delay...

Here we report the outbreak of bacteremia caused by Helicobacter cinaedi (H. cinaedi) in the urology ward. Case 1 was a man in his seventies with prostate cancer. Bacteremia caused by H. cinaedi developed 6 days after robot-assisted radical prostatectomy. Case 2 was a man in his sixties with small cell carcinoma of the prostate. Bacteremia developed at 5 days of docetaxel therapy. Case 3 was a man in his fifties with left renal pelvis carcinoma. Bacteremia developed 3 days after laparoscopic left nephroureterectomy...

Fat embolism is a recognised complication of bony injury and orthopaedic surgery, commonly involving the long bones and pelvis. We report on the case of a 68-year-old renal transplant recipient who developed acute kidney injury following surgical stabilisation of metastatic carcinoma of the acetabulum and replacement of the proximal femur. A CT renal angiogram demonstrated a large fat embolus in the inferior vena cava (IVC) and left iliac veins below the level of IVC filter, with impaired renal perfusion. The risks of open or endovascular lipothrombectomy were felt to outweigh the potential benefits...

PURPOSE: To assess the relationship between De Ritis (aspartate aminotransaminase [AST]/Alanine aminotransaminase [ALT]) ratio and pathological variables and whether it is an independent prognostic factor. MATERIALS AND METHODS: We analyzed 298 consecutive patients who underwent radical or partial nephrectomy for non-metastatic renal cell carcinoma (RCC) between 2006 and 2015. The association between De Ritis ratio and pathological variables including tumor size, presence of renal vein invasion, vena cava invasion, renal capsule infiltration, Gerota fascia invasion, renal sinus involvement, renal pelvic invasion, angiolymphatic invasion, adrenal gland involvement, lymph node involvement, tumor necrosis, and Fuhrman's grade was tested...

Importance: Locoregional failure for patients with locally advanced bladder cancer (LABC) after radical cystectomy (RC) is common even with chemotherapy and is associated with high morbidity and mortality. Adjuvant radiotherapy (RT) can decrease locoregional failure but has not been studied in the chemotherapy era. Objective: To investigate if adjuvant sequential RT plus chemotherapy can improve locoregional recurrence-free survival (LRFS) compared with adjuvant chemotherapy alone...

L-shaped kidney refers to a rare anomaly of the relative kidney positioning. Due to low prevalence, the literature on the co-occurrence of this anomaly with malignancy is lacking. And, if the diagnosis of a renal anomaly does not present difficulties, if a tumor is detected in such a kidney, even MSCT does not always help differentiate a pelvic tumor from a tumor of the renal parenchyma spreading to the pelvicalyceal system. This has important implications for choosing an appropriate surgical strategy. A feature of the presented clinical observation is the co-occurrence of the rare anomaly of kidney position and locally advanced renal cell carcinoma spreading to the renal pelvis...

AIMS: To further characterize biphasic squamoid renal cell carcinoma (RCC), a recently proposed variant of papillary RCC. METHODS AND RESULTS: We identified 28 tumors from multiple institutions. They typically demonstrated two cell populations - larger cells with eosinophilic cytoplasm and higher-grade nuclei, surrounded by smaller, amphophilic cells with scanty cytoplasm. The dual morphology was variable (median 72.5% of tumor, range 5-100%); emperipolesis was found in all cases...
