Purpose: There exists a growing debate as to whether multiparametric magnetic resonance imaging with fusion transrectal ultrasound guided prostate biopsy alone without a standard template biopsy is sufficient to evaluate patients with suspected prostate cancer. 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.
Purpose Evidence from studies of other malignancies has indicated that aggressive local treatment (LT), even in the presence of metastatic disease, is beneficial. Against a backdrop of stagnant mortality rates for metastatic urothelial carcinoma of the bladder (mUCB) at presentation, we hypothesized that high-intensity LT of primary tumor burden, defined as the receipt of radical cystectomy or ≥ 50 Gy of radiation therapy delivered to the bladder, affects overall survival (OS). Patients and Methods We identified 3,753 patients within the National Cancer Data Base who received multiagent systemic chemotherapy combined with high-intensity versus conservative LT for primary mUCB.

Patients And Methods: Using the Premier Hospital Database, we captured patients undergoing a NU with diagnoses of renal pelvis or ureteric neoplasms from 2004 to 2013. We fitted regression models, adjusting for clustering by hospitals and survey weighting to evaluate 90-day postoperative complications, operating-room time (OT), prolonged length of stay (pLOS), and direct hospital costs among open (ONU), laparoscopic (LNU) and robotic (RNU) approaches.
Purpose: We evaluate the contemporary incidence and consequences of postoperative rhabdomyolysis after extirpative renal surgery.
Materials And Methods: We conducted a population based, retrospective cohort study of patients who underwent extirpative renal surgery with a diagnosis of a renal mass or renal cell carcinoma in the United States between 2004 and 2013. Regression analysis was performed to evaluate 90-day mortality (Clavien grade V), nonfatal major complications (Clavien grade III-IV), hospital readmission rates, direct costs and length of stay.
Background: Targeted therapies (TTs) have revolutionized metastatic renal cell carcinoma (mRCC) treatment in the past decade, largely replacing immunotherapy including high-dose interleukin-2 (HD IL-2) therapy. We evaluated trends in HD IL-2 use for mRCC in the TT era.
Methods: Our cohort comprised a weighted estimate of all patients undergoing HD IL-2 treatment for mRCC from 2004 to 2012 using the Premier Hospital Database.
Objective: To conduct the first study of intra- and postoperative outcomes related to intraoperative resident involvement in transurethral resection procedures for benign prostatic hyperplasia and bladder cancer in a large, multi-institutional database.
Design: Relying on the American College of Surgeons National Surgical Quality Improvement Program Participant User Files (2005-2012), we abstracted all cases of endoscopic prostate surgery (EPS) for benign prostatic hyperplasia and transurethral resection of bladder tumors (TURBTs). Multivariable logistic regression models were constructed to assess the effect of trainee involvement (postgraduate year [PGY] 1-2: junior, PGY 3-4: senior, PGY ≥ 5: chief or fellow) vs attending only on operative time and length of hospital stay, as well as 30-day complication, reoperation, and readmission rates.
Objective: To perform a population-based study that evaluates contemporary racial disparities in the morbidity profile of patients undergoing radical nephrectomy in the United States.
Methods: Using the Premier hospital database (Premier Inc, Charlotte, NC), which collects data from over 600 nonfederal hospitals throughout the United States, we identified patients undergoing a total nephrectomy as their primary procedure and also had a concurrent diagnosis of a kidney mass or cancer from 2003 to 2010. The primary outcome was 90-day major complication rates, based on the Clavien classification system.
Introduction: To identify and assess predictive factors for positive surgical margins (PSM) in patients undergoing radical prostatectomy (RP).
Materials And Methods: An Institution Review Board (IRB) approved retrospective review of 1751 patients that underwent RP from March 2000 to June 2013 was performed. Identified were 1740 patients whom had not received neoadjuvant therapy; these were used for the purpose of this analysis.
Introduction: New treatment options for metastatic castration resistant prostate cancer (mCRPC) have become available over the last few years should primary treatments and androgen deprivation therapies fail. While historically not considered to be amenable to immunotherapy, the treatment of advanced prostate cancer using this approach is an area of intense interest and now clinical application.
Materials And Methods: Recent literature on castration resistant prostate cancer management with a focus on immunotherapeutic strategies was reviewed.
In patients with non-muscle invasive bladder cancer, fluorescence cystoscopy can improve the detection and ablation of bladder tumors. In this paper we describe the technique and practical aspects of hexaminolevulinate (HAL) fluorescence cystoscopy, also known as "blue light cystoscopy".
