Objective: To evaluate the risk upgrading of active surveillance (AS), we reviewed the outcomes of African American men (AA) after electing AS. AS is the standard of care for men with low-grade prostate cancer (PCa). AA are known to have more advanced PCa features and are more likely to die from PCa, thus subsequent disease progression for AA on AS is unclear.

However, past efforts to effectively collaborate with advanced practice provider associations, particularly SUNA (the Society of Urologic Nurses and Associates), have been unsuccessful. We define a path forward for the AUA to achieve the goal of mutually beneficial partnership.

Poor outcomes are likely with endoscopic and radiologic management, and definitive surgical treatment can cause significant morbidity. The comparative advantages of an operative approach have not yet been fully described in the literature.

The optimal approach is controversial and can be influenced by multiple factors. This study aimed to investigate the influence of geographic region on the selection of treatment for prostate cancer.

However, continued technological and surgical advances have ultimately led to the robotic approach. Continued advances in minimally invasive surgery have led to shorter hospital stays and hastened recovery.

We report a case of surgical resection of a large, symptomatic renal artery aneurysm from an entirely robotic approach.

We sought to determine predictors of subsequent detection and risk stratification of PCa in a racially diverse group of men with atypical small acinar proliferation (ASAP) on initial prostate biopsy.
Materials And Methods: A retrospective analysis was conducted on data from men with ASAP on initial prostate biopsy who subsequently received confirmatory biopsies between September 2000 and July 2015.
Prostate cancer (PC) is the most common and the second leading cause of cancer-related death among American men. Early diagnosis is a prerequisite to improving therapeutic benefits. However, the current clinical biomarkers for PC do not reliably decipher indolent PC from other urogenital disorders.
View Article and Find Full Text PDFSurgical management of ureteropelvic junction obstruction (UPJO) has historically been performed with open pyeloplasty. With the advent of endourology, laparoscopy, and robotics, minimally-invasive techniques have been described and accepted as alternatives to open surgery. Each of these approaches has its own advantages and disadvantages, equipment needs, degree of invasiveness, and experience of the treating urologist.

We sought to evaluate the utility of prostate biopsies directed toward the APZ in a predominantly AA cohort.
Methods And Materials: We reviewed all patients with PCa found on biopsy schema that included needle biopsies directed at both the peripheral zone (PZ) and APZ from 2010 to 2014.
Purpose: Prostate specific antigen has decreased performance characteristics for the detection of prostate cancer in African-American men. We evaluated urinary PCA3 and TMPRSS2:ERG in a racially diverse group of men.
Materials And Methods: After institutional review board approval, post-examination urine was prospectively collected before prostate biopsy.
In pursuit of improving the quality of residents' education, the Southeastern Section of the American Urological Association (SES AUA) hosts an annual robotic training course for its residents. The workshop involves performing a robotic live porcine nephrectomy as well as virtual reality robotic training modules. The aim of this study was to evaluate workload levels of urology residents when performing a live porcine nephrectomy and the virtual reality robotic surgery training modules employed during this workshop.

Methods: Between March 2007 and March 2014, there were 730 patients who underwent kidney transplant (KTx) at our institution. We identified 16 patients with TUS, occurring more than 60 days after KTx.
Purpose: The causes of disproportionate incidence and mortality of prostate cancer among African Americans (AA) remain elusive. The purpose of this study was to investigate the mechanistic role and assess clinical utility of the splicing factor heterogeneous nuclear ribonucleoprotein H1 (hnRNP H1) in prostate cancer progression among AA men.
Experimental Design: We employed an unbiased functional genomics approach coupled with suppressive subtractive hybridization (SSH) and custom cDNA microarrays to identify differentially expressed genes in microdissected tumors procured from age- and tumor grade-matched AA and Caucasian American (CA) men.
Objective: To evaluate the effect of 3-dimensionally (3D) printed physical renal models with enhancing masses on medical trainee characterization, localization, and understanding of renal malignancy.
Methods: Proprietary software was used to import standard computed tomography (CT) cross-sectional imaging into 3D printers to create physical models of renal units with enhancing renal lesions in situ. Six different models were printed from a transparent plastic resin; the normal parenchyma was printed in a clear, translucent plastic, with a red hue delineating the suspicious renal lesion.
Purpose: To assess determinants of performance applying the tasks of the Basic Laparoscopic Urologic Surgery (BLUS) skills curriculum administered at a single institution.
Methods: After obtaining institutional review board approval, fourth-year medical students, urology residents (postgraduate year 1-5), and staff attending surgeons from an academic institution were recruited. Participants were grouped by level of experience and evaluated on 4 different BLUS modules testing fundamental laparoscopic techniques from September 2012 to September 2013.
Active surveillance (AS) is a treatment strategy for prostate cancer (PCa) whereby patients diagnosed with PCa undergo ongoing characterization of their disease with the intent of avoiding radical treatment. Previously, AS has been demonstrated to be a reasonable option for men with low-risk PCa, but existing cohorts largely consist of Caucasian Americans. Because African Americans have a greater incidence, more aggressive, and potentially more lethal PCa than Caucasian Americans, it is unclear if AS is appropriate for African Americans.
View Article and Find Full Text PDFObjective: To construct high-fidelity, patient customized, physical, 3-dimensional (3D) models of renal units with enhancing renal lesions identified on cross-sectional imaging, which may aid patients, trainees, and clinicians in their comprehension, characterization, localization, and extirpation of suspicious renal masses.
Methods: Specialized software was used to import patient's diagnostic computerized tomography cross-sectional imaging into 3D printers and create physical 3D models of renal units with enhancing in situ lesions. Patients and trainees had the opportunity to manipulate the individualized model before surgical resection.
Emerging evidence suggests that mesenchymal stem cells (MSCs) are often recruited to tumor sites but their functional significance in tumor growth and disease progression remains elusive. Herein we report that prostate cancer (PC) cell microenvironment subverts PC patient adipose-derived stem cells (pASCs) to undergo neoplastic transformation. Unlike normal ASCs, the pASCs primed with PC cell conditioned media (CM) formed prostate-like neoplastic lesions in vivo and reproduced aggressive tumors in secondary recipients.

The objective of this study was to examine serum estrogens and prostate tumor ERβ expression and examine their correlation with clinical and pathological parameters in African American (AA) versus Caucasian American (CA) men. The circulating 17β-estradiol (E2) was measured by enzyme immunoassay in blood procured from racially stratified normal subjects and PCa patients.

Patients And Methods: We retrospectively reviewed the records of 24 patients with ureteral obstruction secondary to advanced cervical carcinoma, stage T3b (n=10) and T4 (n=14), that was relieved by Wallstents. Nineteen patients needed bilateral and 5 needed unilateral Wallstents to relieve the obstruction.
