OBJECTIVE: To provide a training tool to address the technical challenges of robot-assisted laparoscopic partial nephrectomy, we created silicone renal tumor models using 3-dimensional printed molds of a patient's kidney with a mass. In this study, we assessed the face, content, and construct validity of these models. MATERIALS AND METHODS: Surgeons of different training levels completed 4 simulations on silicone renal tumor models. Participants were surveyed on the usefulness and realism of the model as a training tool...

Benign prostatic hyperplasia (BPH) is characterized by an enlarged prostate, lower urinary tract symptoms (LUTS), and a decreased urinary flow rate. Common in older men, BPH is a progressive disease that can eventually lead to complications including acute urinary retention (AUR) and the need for BPH-related surgery. Both normal and abnormal prostate growth is driven by the androgen dihydrotestosterone (DHT), which is formed from testosterone under the influence of 5-alpha reductase. Thus, 5-alpha reductase inhibitors (5-ARIs) effectively reduce the serum and intraprostatic concentration of DHT, causing an involution of prostate tissue...

PURPOSE: Although many factors have been proposed to trigger symptom exacerbations ("flares") in patients with interstitial cystitis/bladder pain syndrome and chronic prostatitis/chronic pelvic pain syndrome, few studies have investigated these factors empirically. Therefore, we embedded a case-crossover study in the Multidisciplinary Approach to the Study of Chronic Pelvic Pain longitudinal study to evaluate a range of patient-reported triggers. MATERIALS AND METHODS: Exposure to proposed triggers (diet, physical activities, sedentary behaviors, stress, sexual activities, infection-like symptoms, and allergies) was assessed by questionnaire a maximum of three times when participants reported flares and at three randomly-selected times...

BACKGROUND: Epidemiologic evidence for a serum cholesterol-prostate cancer link is mixed. Prostate-specific antigen (PSA) is positively correlated with cholesterol, potentially increasing PSA-driven biopsy recommendations in men with high cholesterol, though biopsy compliance may be lower in men with comorbid conditions. These potential biases may affect PSA-driven biopsy rates and subsequent prostate cancer detection in men with high serum cholesterol. Our objective was to test the association between serum cholesterol and prostate cancer risk in men receiving PSA independent, study-mandated prostate biopsies...

OBJECTIVES: To examine the incremental value of prostate MRI when used in combination with the currently available preoperative risk stratification tool the Memorial Sloan Kettering Cancer Center Pre-Radical Prostatectomy Nomogram (MSKCC). METHODS: We reviewed our institutional database of prostate MRI performed prior to radical prostatectomy between December 2014 and March 2016 (n=236). We generated a logistic regression model based on observed final pathology results and the MSKCC nomogram predictions for organ confined disease, extracapsular extension (ECE), seminal vesicle invasion (SVI), and lymph node (LN) involvement ('MSKCC Only')...

BACKGROUND: The European Randomized Study of Screening for Prostate Cancer (ERSPC) demonstrated that prostate-specific antigen (PSA) screening significantly reduced prostate cancer mortality (rate ratio, 0.79; 95% confidence interval, 0.69-0.91). The US Prostate, Lung, Colorectal, and Ovarian (PLCO) trial indicated no such reduction but had a wide 95% CI (rate ratio for prostate cancer mortality, 1.09; 95% CI, 0.87-1.36). Standard meta-analyses are unable to account for key differences between the trials that can impact the estimated effects of screening and the trials' point estimates...

BACKGROUND: Prostate atrophy (PA) is commonly identified in prostate biopsies. Previous studies suggest PA may be associated with lower PCa risk. However, it remains unclear whether PA is associated with smaller, less aggressive, and less advanced tumors. Thus, we sought to determine whether the presence and severity of baseline PA in men with initial biopsy negative for prostate cancer (PCa) is associated with PCa volume at 2- and 4-year repeat biopsy. METHODS: We performed a retrospective analysis of 927 men 50-75-years-old with negative baseline biopsy and positive 2- or 4-year repeat biopsy for PCa in the Reduction by Dutasteride of PCa Events study...

Much attention has been given to machine learning and its perceived impact in radiology, particularly in light of recent success with image classification in international competitions. However, machine learning is likely to impact radiology outside of image interpretation long before a fully functional "machine radiologist" is implemented in practice. Here, we describe an overview of machine learning, its application to radiology and other domains, and many cases of use that do not involve image interpretation...

Prostate cancer (PC) risk differs between races, and we previously showed prostate inflammation in benign prostate tissue was linked with a lower future PC risk. However, whether prostate tissue inflammation varies by race is unknown. We analyzed baseline acute and chronic prostate inflammation by race in REDUCE, a 4-year, multicenter, placebo-controlled study where all men had a negative prostate biopsy prior to enrollment. We included 7,982 men with standardized central pathology review to determine the presence or absence of chronic or acute inflammation in baseline prostate biopsy tissue...

The size and diversity of the physician-scientist workforce are issues of national concern. In this retrospective, national cohort study of US medical school matriculants who graduated in 1997-2004, we describe the prevalence and predictors of federal F32, mentored-K, and R01 awards among physicians. In multivariable logistic regression models, we identified demographic, educational, and professional development variables independently associated with each award through August 2014, reporting adjusted odds ratios and 95% confidence intervals (AOR (95% CI))...

PURPOSE: Although lower urinary tract symptoms and sleep problems often develop together, to our knowledge it is unknown whether sleep disturbances are linked to lower urinary tract symptoms development and progression. As measured by the 6-item MOS-Sleep (Medical Outcomes Study Sleep Scale) survey we examined the relationship of sleep problems to the development and progression of lower urinary tract symptoms in the REDUCE (Reduction by Dutasteride of Prostate Cancer Events) study. MATERIALS AND METHODS: REDUCE was a randomized trial testing prostate cancer chemoprevention with dutasteride in men with prostate specific antigen 2...

Background: The ERSPC (European Randomized Study of Screening for Prostate Cancer) found that screening reduced prostate cancer mortality, but the PLCO (Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial) found no reduction. Objective: To evaluate whether effects of screening on prostate cancer mortality relative to no screening differed between the ERSPC and PLCO. Design: Cox regression of prostate cancer death in each trial group, adjusted for age and trial...

PURPOSE: Mentored K (K01/K08/K23) career development awards are positively associated with physicians' success as independent investigators; however, individuals in some racial/ethnic groups are less likely to receive this federal funding. The authors sought to identify variables that explain (mediate) the association between race/ethnicity and mentored K award receipt among U.S. Liaison Committee for Medical Education-accredited medical school graduates who planned research-related careers...

BACKGROUND: We previously found no significant differences in mortality between men who underwent surgery for localized prostate cancer and those who were treated with observation only. Uncertainty persists regarding nonfatal health outcomes and long-term mortality. METHODS: From November 1994 through January 2002, we randomly assigned 731 men with localized prostate cancer to radical prostatectomy or observation. We extended follow-up through August 2014 for our primary outcome, all-cause mortality, and the main secondary outcome, prostate-cancer mortality...

Chronic pain is often measured with a severity score that overlooks its spatial distribution across the body. This widespread pain is believed to be a marker of centralization, a central nervous system process that decouples pain perception from nociceptive input. Here, we investigated whether centralization is manifested at the level of the brain using data from 1079 participants in the Multidisciplinary Approach to the Study of Chronic Pelvic Pain Research Network (MAPP) study. Participants with a clinical diagnosis of urological chronic pelvic pain syndrome (UCPPS) were compared to pain-free controls and patients with fibromyalgia, the prototypical centralized pain disorder...
