Angiomyolipoma rupture: does size always matter?

Cent European J Urol 2021 25;74(1):48-50. Epub 2021 Feb 25.

University of Zielona Góra, Collegium Medicum, Department of Urology, Zielona Góra, Poland.

Angiomyolipoma (AML) is the most common benign renal neoplasm. Although asymptomatic lesions rarely lead to clinical dilemma, the management of ruptured tumours can become challenging. The size of the tumour has been widely accepted as a prognostic factor for intervention but there exists some evidence against considering the size as the only prognostic factor for intervention in AML.

Laparoendoscopic single-site simultaneous bilateral nephrectomy: first reported case series.

Cent European J Urol 2021 15;74(1):44-47. Epub 2021 Jan 15.

Clinic Institute of Nephrology and Urology (ICNU), Universidad de Barcelona, Barcelona, Spain.

Bilateral renal tumors in patients on dialysis are usually managed with bilateral nephrectomy. With traditional laparoscopy, this procedure requires the insertion of multiple trocars. Laparoendoscopic single-site surgery (LESS) uses a single umbilical incision to insert multiple instruments and is also employed for extraction of specimens. Read More

CircEHD2, CircNETO2 and CircEGLN3 as Diagnostic and Prognostic Biomarkers for Patients with Renal Cell Carcinoma.

Cancers (Basel) 2021 Apr 30;13(9). Epub 2021 Apr 30.

Department of Urology, University Hospital Bonn, 53127 Bonn, Germany.

Background: Circular RNA (circRNA) plays an important role in the carcinogenesis of various tumors. It is assumed that circRNAs have a high tissue and tumor specificity, thus they are discussed as cancer biomarkers. The knowledge about circRNAs in clear cell renal carcinoma (ccRCC) is limited so far, and thus we studied the expression profile of seven circRNAs (circCOL5A1, circEHD2, circEDEM2, circEGNL3, circNETO2, circSCARB1, circSOD2) in a cohort of ccRCC patients.

Cancers (Basel) 2021 Apr 27;13(9). Epub 2021 Apr 27.

Department of Biomedical Sciences and Human Oncology, University of Bari, 70122 Bari, Italy.

Renal cell carcinoma (RCC) is one of primary cancers that frequently metastasize to the brain. Brain metastasis derived from RCC has the propensity of intratumoral hemorrhage and relatively massive surrounding edema. Moreover, it confers a grim prognosis in a great percentage of cases with a median overall survical (mOS) around 10 months. Read More

Multidisciplinary surgical approach to renal cancer with vena cava invasion and pulmonary embolism.

Rozhl Chir 2021 ;100(2):88-93

Introduction: Renal cancer is unique for many reasons. One reason is that renal cell carcinoma can grow directly into the drainage veins of the kidney, which enter the inferior vena cava leading to the heart. This growth of tumor cells into the veins is called a tumor thrombus and is a locally aggressive renal cancer. Read More

Is preoperative neutrophil-to-lymphocyte ratio a red flag which can predict high-risk pathological characteristics in renal cell carcinoma?

Urol Ann 2021 Jan-Mar;13(1):47-52. Epub 2021 Jan 19.

Department of Biochemistry, Kasturba Medical College Hospital, Mangalore, Karnataka, India.

Introduction: Renal cell carcinoma (RCC) is known to invoke both immunological and inflammatory responses. While the neutrophils mediate the tumor-induced inflammatory response, the lymphocytes bring about the various immunological events associated with it. The neutrophil-to-lymphocyte ratio (NLR) is a simple indicator of this dual response. Read More
