Extra-adrenal, functional paraganglioma, if not medically controlled, requires early surgical resection. This can often be challenging when found in a retroperitoneal location, where resections are prone to lymphatic disruption and chyle leaks. Chylous ascites carry a significant risk of protein and caloric malnutrition, dehydration, and even mortality given the nutrient-rich characteristic of lost lymphatic fluid.

We present a 74-year-old male with previously resected primary EMPD who presented with widespread PSMA-avid lesions without prostatic uptake, an elevated PSA >100, and a negative prostate biopsy. Based on this and immunohistological staining, recurrent EMPD was suspected.

We sought to determine if resolution of PNS by one year after cytoreductive nephrectomy was significantly associated with improved overall survival (OS) and cancer-specific survival (CSS). We retrospectively reviewed a prospectively maintained nephrectomy database for patients with any histology metastatic RCC (mRCC) who underwent nephrectomy between 2000 and 2022.

Materials And Methods: We conducted a cross-sectional study with data collected retrospectively in the Neurosurgery Department of the Central and General Hospitals of Yaounde from January 2010 to December 2019.
Cabozantinib is an oral multikinase inhibitor approved for treatment in metastatic renal cell carcinoma (RCC). We hypothesized that neoadjuvant cabozantinib could downstage localized tumors, facilitating partial nephrectomy, and facilitating surgery in patients with locally advanced tumors that would require significant adjacent organ resection. We, therefore, conducted a phase 2, single-arm trial of cabozantinib treatment for 12 weeks in 17 patients with locally advanced biopsy-proven non-metastatic clear cell RCC before surgical resection.

Methods: A bi-institutional retrospective review of all patients who underwent their first (virgin) AUS placement after pelvic RT between January 1, 2011 and July 1, 2023. To determine the optimal timeline for device implantation 2-5years post-RT, we compared hazard ratios for device revision/explantation (Rev/Exp) using Kaplan-Meier curves for each year (earlier vs later than 2/3/4/5 years post-RT).
Purpose: To compare the lifespan of first transcorporal cuff (TC) placement of an artificial urinary sphincter (AUS) versus standard placement (SP) in patients with prior radiotherapy (RT) for prostate cancer (PCa).
Methods: We reviewed first (virgin) AUS placements from two high-volume care centers between 1/2011 and 1/2021, including PCa patients with RT history. AUS lifespan was assessed via the hazard ratio of device explantation and/or revision within a ten-year timeframe for the TC vs.
Introduction: Surgical decision-making often relies on a surgeon's subjective assessment of a patient's frailty status to undergo surgery. Certain patient demographics can influence subjective judgment when compared to validated objective assessments. In this study, we explore the relationship between subjective and objective frailty assessments according to patient age, sex, and race.

Methods: We retrospectively investigated our institutional RCC database for patients who underwent PN for RCC from 1997 to 2018. Decision for technique was at the discretion of the operating urologist, following practice patterns and training history.
Introduction: Baseline sarcopenia and postoperative changes in muscle mass are independently associated with overall survival (OS) in patients with metastatic renal cell carcinoma (mRCC) undergoing cytoreductive nephrectomy (CN). Here we examine the relationships between preoperative (baseline), postoperative changes in muscle quantity, and survival outcomes following CN as determined by linear segmentation, a clinic-friendly tool that rapidly estimates muscle mass.
Materials And Methods: Our nephrectomy database was reviewed for patients with metastatic disease who underwent CN for RCC.
Objective: To examine the performance of the Palacios et al [Aguilar Palacios D, Wilson B, Ascha M, et al. New baseline renal function after radical or partial nephrectomy: a simple and accurate predictive model. J Urol.
View Article and Find Full Text PDFBackground: The 2018 Leibovich prognostic model for nonmetastatic renal cell carcinoma (RCC) combines clinical, surgical, and pathologic factors to predict progression-free survival (PFS) and cancer-specific survival (CSS) for patients with clear cell (ccRCC), papillary (pRCC), and chromophobe (chRCC) histology. Despite high accuracy, <1% of the original cohort was Black. Here, the authors examined this model in a large population with greater Black patient representation.

Furthermore, low Cr/Cys-C is associated with decreased overall survival (OS), but to date, has not been examined in patients with renal cell carcinoma (RCC). Our objective is to evaluate associations between low Cr/Cys-C ratio and OS and recurrence-free survival (RFS) in patients with RCC treated with nephrectomy.
View Article and Find Full Text PDFPurpose: Gleason grade (GG) on prostate biopsy is important for risk stratification and clinical decision making. Multiparametric MRI (mpMRI) improved detection of clinically significant disease and some studies suggest that MRI-fusion biopsy combined with systematic biopsy results in fewer upgrades on final surgical pathology. However, the downgrade rate is unclear and there is controversy in the literature.

Simultaneously, making data freely accessible can raise ethical questions regarding the participants' privacy. We first outline the challenges regarding "open data" for researchers in light of the GDPR.

Our objective was to describe our experience with fusion targeted prostate biopsy and assess whether it could obviate the need for concomitant standard 12-core template prostate biopsy.
Materials And Methods: We retrospectively reviewed our prospectively collected database of patients who underwent fusion transrectal ultrasound guided prostate biopsy.
