AUA 2018: Office-Based Ultrasound-Guided Percutaneous Renal Mass Biopsy

San Francisco, CA USA (UroToday.com) Cyrus Lin, MD from the University of California, Irvine (UCI), presented data on the feasibility, safety, and efficacy of office-based, ultrasound-guided percutaneous renal biopsy. As an introduction to his talk, Lin explained that the recent rise of imaging-driven incidences of small renal cortical neoplasms has created an interest in a “biopsy before treatment” approach. In this multicenter study, Lin and team prospectively evaluated the efficacy of urologist performed, office based, ultrasound guided, percutaneous renal biopsy (USPRB).

AUA 2018: Characterizing the Incidence, Predictors, and Survival of Disappearing Renal Tumors from the DISSRM Registry

San Francisco, CA (UroToday.com) Previous literature has described spontaneous tumor regression, the disappearance of a mass without intervention, particularly with renal tumors. Clinical regression may occur as an immunologic phenomenon, but may also reflect the variable sensitivity of tumor imaging. While important, evidence regarding disappearing renal tumors (DRTs) remains sparse. The authors aimed to quantify the prevalence of DRTs among small renal masses, identify potential predictors, and characterize their survival. 

AUA 2018: Shared Decision Making for Treatment of Small Renal Masses: a Survey of Patients' Opinions Before and After Initial Counseling

San Francisco, CA (UroToday.com) In addition to surgery, percutaneous biopsy, thermal ablation and active surveillance are increasingly used in the management of patients with small renal masses (SRM). Few studies have investigated patient attitudes towards nonsurgical SRM treatments. The objective of this study was to evaluate patients’ opinions regarding renal mass biopsy, thermal ablation and surveillance for SRM management. 

AUA 2018: Comparison Between Liver Derotation with Pringle Manoeuvre and Cardiopulmonary Bypass with Deep-Hypothermic Cardiac Arrest for Kidney Cancer with Mayo Level III Tumor Thrombus

San Francisco, CA (UroToday.com) The absolute need for cardiopulmonary bypass (CPB) and deep-hypothermic cardiac arrest (DHCA) in patients with renal cell carcinoma (RCC) and level III tumor thrombus is still debated. This study aimed to compare intra-, peri- and postoperative outcomes of patients undergoing liver de-rotation and Pringle maneuver (Group A) to patients undergoing CBP and DHCA (Group B) in patients with RCC and Mayo level III tumor thrombus. 

AUA 2018: Effect of African-American Race on Cancer Specific Mortality Differs According to Clear-Cell vs Non-Clear Cell Histologic Subtype in Metastatic Renal Cell Carcinoma

San Francisco, CA (UroToday.com) The potential effect of race (African-American vs. Caucasian), was never examined in the setting of cancer specific mortality (CSM) in clear cell vs. non-clear cell metastatic renal cell carcinoma (ccmRCC vs. non-ccmRCC). The authors presented a study assessing the impact of race on these outcomes. 

AUA 2018: Oncological and Functional Outcomes in Minimally Invasive Approach for Kidney Cancer with Venous Thrombus

San Francisco, CA (UroToday.com) In case of localized kidney cancer (KC) without venous thrombus (VT) minimally invasive (MI) procedure is commonly used. However little evidence exists on the usage of this approach for the treatment of KC with VT.  A multicenter cohort of 2245 patients was analyzed. A total of 120 patients who underwent an MI approach with a diagnosis of KC + VT (T stage >=3a), were included in the analysis.

AUA 2018: Outcomes of Partial Versus Radical Nephrectomy in Octogenarian Patients: Results from the RESURGE Project

San Francisco, CA (UroToday.com) An increasing number of localized kidney cancers are being diagnosed in elderly people, raising the issue of which is the optimal surgical management in this subset of patients. The aim of this study was to compare surgical, functional and oncological outcomes of partial (PN) versus radical nephrectomy (RN) in a multi-institutional cohort of elderly patients from 23 European, US and Asian Institutions (REnal SUrgery in the Elderly - RESURGE - project).
