Introduction: Results from prior studies show contradictory evidence in determining whether utilization of renal ischemia during partial nephrectomies (PN) results in worse renal functional outcomes. Data assessing a large cohort of patients with no ischemia PN are lacking. The purpose of this study was to evaluate whether the use and type of renal ischemia during PN affects renal functional outcomes.

We report the final data analysis of the safety, overall response rate (ORR), progression-free survival (PFS), and overall survival (OS) of the phase I patients and seven expansion cohorts.
Methods: This is an investigator-initiated, multicenter, phase I trial.
The role of germline genetic testing in urologic oncology has expanded in recent years. However, implementation of genetic testing in community practices remains a challenge, often due to limited access to qualified genetics trained providers. In this study, we report outcomes of a universal germline screening program in a community urology practice.

Objective: To employ a novel scoring equation (multiplex score [MS]) derived from RNS to assess outcomes of multiplex PN at our institution.
Purpose: This study investigated the efficacy and tolerability of cabozantinib plus nivolumab (CaboNivo) in patients with metastatic urothelial carcinoma (mUC) that progressed on checkpoint inhibition (CPI).
Patients And Methods: A phase I expansion cohort of patients with mUC who received prior CPI was treated with cabozantinib 40 mg/day and nivolumab 3 mg/kg every 2 weeks until disease progression/unacceptable toxicity. The primary goal was objective response rate (ORR) per RECIST v.
BK virus (BKV)-hemorrhagic cystitis (HC) is a well-known and rarely fatal complication of hematopoietic stem cell transplantation (HSCT). Treatment for BKV-HC is limited, but virus-specific T-cells (VST) represent a promising therapeutic option feasible for use posttransplant. We report on the case of a 16-year-old male with dedicator of cytokinesis 8 (DOCK8) deficiency who underwent haploidentical HSCT complicated by severe BKV-HC, catastrophic renal hemorrhage, and VST-associated cytokine release syndrome (CRS).

The primary objective of this study was to determine the clinical value of fluorine-18 2-fluoro-2-deoxy-D-glucose (F-FDG) PET/MRI for surveillance and restaging of patients with muscle-invasive, locally advanced, and metastatic bladder cancer compared to conventional imaging methods.
Materials And Methods: This retrospective study enrolled patients with muscle-invasive, locally advanced and metastatic bladder cancer in a single institute evaluated with F-FDG PET/MRI.
Purpose: Active surveillance for patients with low and intermediate risk prostate cancers is becoming a more utilized option in recent years. However, the use of magnetic resonance imaging and imaging-targeted biopsy for monitoring grade progression has been poorly studied in this population. We aim to define the utility of magnetic resonance imaging-targeted biopsy and systematic biopsy in an active surveillance population.

CTCs uniquely allow for digital pathology of individual malignant cell morphology and marker expression. We compared CTC features and T-cell counts with survival endpoints in a cohort of patients with metastatic genitourinary cancer treated with combination immunotherapy.

Patients And Methods: Patients received escalating doses of CaboNivo or CaboNivoIpi. The primary objective was to establish a recommended phase II dose (RP2D).

Prostate cancer is the most frequently diagnosed cancer in men after skin cancer. Owing to the rising popularity of prostate-specific antigen screening, large numbers of patients are receiving a diagnosis of prostate cancer and undergoing whole-gland treatment. Some patients with a diagnosis of low-risk, localized disease may not benefit from whole-gland treatment, however, given its known morbidity.

Circulating tumor cells and DNA (CTCs, ctDNA) are two biologically distinct "liquid biopsies" that may potentially address this need, although they have been understudied in UC to date and their relative utility is unknown. To this end, matched CTC and ctDNA samples were collected for a head-to-head comparison in a pilot study of 16 patients with metastatic UC.

To date, the majority of work on this topic has utilized the CellSearch test, which has limited sensitivity due to reliance on positive selection for the cell surface protein epithelial cell adhesion molecule (EpCAM). We used a novel selection-free method to enumerate and characterize CTCs across a range of UC stages.

It is unclear how frequently this occurs in localized disease and existing detection methods rely on epithelial markers with low specificity and sensitivity. We used multiple methodologies of disseminated tumor cell detection in bone marrow harvested at radical prostatectomy.

Currently, a plethora of methods is available for the detection of these rare cells. We compared the outcomes of two of those methods to enumerate and characterize CTCs in patients with locally advanced and metastatic prostate cancer (PCa).

Pathways of this type have been shown to decrease the length of stay (LOS) and postoperative ileus. However, concerns persist that ERAS is costly and increases readmissions.

Existing guidelines recommend against LND at the time of radical prostatectomy (RP) in low-risk men, yet this is still a common practice.

Introduction: Circulating tumor cells (CTCs) have great potential as circulating biomarkers for solid malignancies. Currently available assays for CTC detection rely on epithelial markers with somewhat limited sensitivity and specificity. We found that the staining pattern of nucleolin, a common nucleolar protein in proliferative cells, separates CTCs from white blood cells (WBCs) in men with metastatic prostate cancer.
View Article and Find Full Text PDFBackground: The newly proposed five-tiered prostate cancer grading system (PCGS) divides Gleason score (GS) 8-10 disease into GS 8 and GS 9-10 on the basis of biochemical recurrence (BCR) following radical prostatectomy (RP) as an outcome. However, BCR does not necessarily portend worse survival outcomes.
Objective: To assess the significance of distinguishing GS 8 versus 9-10 disease in terms of long-term survival outcomes for both the preoperative setting using biopsy (Bx) GS and the postoperative setting with RP GS.
Purpose: Gleason score is one of the most important prognostic indicators for prostate cancer. Downgrading from biopsy Gleason score 7 to radical prostatectomy Gleason score 6 occurs commonly and yet to our knowledge the impact on survival outcomes is unknown. We examined biochemical recurrence and prostate cancer specific mortality risk in a large cohort evaluated by a single group of expert urological pathologists.

The aim of this study was to evaluate the effect of blood storage duration on the risk of adverse perioperative outcomes in this high-risk patient population.
Materials And Methods: In a retrospective review of RC patients from 2010 to 2014 who received PBTs, the average storage duration for all units transfused was used to classify patients as receiving older blood using 3 different definitions (≥21 days,≥28 days, and≥35 days).
In the current era of individualized medicine, a biorepository of human samples is essential to support clinical and translational research. There have been limited efforts in this arena within the field of urology, as cost, logistical and ethical issues represent significant deterrents to biobanking. The Johns Hopkins Brady Urological Institute Biorepository was founded in 1994 as a resource to facilitate discovery.
