Abstract
BACKGROUND Tissue preservation strategies have been increasingly used for the management of localized prostate cancer. Focal ablation using ultrasound-guided high-intensity focused ultrasound (HIFU) has demonstrated promising short and medium-term oncological outcomes. Advancements in HIFU therapy such as the introduction of tissue change monitoring (TCM) aim to further improve treatment efficacy. OBJECTIVE To evaluate the association between intraoperative TCM during HIFU focal therapy for localized prostate cancer and oncological outcomes 12 mo afterward. DESIGN, SETTING, AND PARTICIPANTS Seventy consecutive men at a single institution with prostate cancer were prospectively enrolled. Men with prior treatment, metastases, or pelvic radiation were excluded to obtain a final cohort of 55 men. INTERVENTION All men underwent HIFU focal therapy followed by magnetic resonance (MR)-fusion biopsy 12 mo later. Tissue change was quantified intraoperatively by measuring the backscatter of ultrasound waves during ablation. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Gleason grade group (GG) ≥2 cancer on postablation biopsy was the primary outcome. Secondary outcomes included GG ≥1 cancer, Prostate Imaging Reporting and Data System (PI-RADS) scores ≥3, and evidence of tissue destruction on post-treatment magnetic resonance imaging (MRI). A Student's t - test analysis was performed to evaluate the mean TCM scores and efficacy of ablation measured by histopathology. Multivariate logistic regression was also performed to identify the odds of residual cancer for each unit increase in the TCM score. RESULTS AND LIMITATIONS A lower mean TCM score within the region of the tumor (0.70 vs 0.97, p = 0.02) was associated with the presence of persistent GG ≥2 cancer after HIFU treatment. Adjusting for initial prostate-specific antigen, PI-RADS score, Gleason GG, positive cores, and age, each incremental increase of TCM was associated with an 89% reduction in the odds (odds ratio: 0.11, confidence interval: 0.01-0.97) of having residual GG ≥2 cancer on postablation biopsy. Men with higher mean TCM scores (0.99 vs 0.72, p = 0.02) at the time of treatment were less likely to have abnormal MRI (PI-RADS ≥3) at 12 mo postoperatively. Cases with high TCM scores also had greater tissue destruction measured on MRI and fewer visible lesions on postablation MRI. CONCLUSIONS Tissue change measured using TCM values during focal HIFU of the prostate was associated with histopathology and radiological outcomes 12 mo after the procedure. PATIENT SUMMARY In this report, we looked at how well ultrasound changes of the prostate during focal high-intensity focused ultrasound (HIFU) therapy for the treatment of prostate cancer predict patient outcomes. We found that greater tissue change measured by the HIFU device was associated with less residual cancer at 1 yr. This tool should be used to ensure optimal ablation of the cancer and may improve focal therapy outcomes in the future.

Abstract
PURPOSE To evaluate the performance of multiparametric magnetic resonance imaging (mpMRI) and PSA testing in follow-up after high intensity focused ultrasound (HIFU) focal therapy for localized prostate cancer. METHODS A total of 73 men with localized prostate cancer were prospectively enrolled and underwent focal HIFU followed by per-protocol PSA and mpMRI with systematic plus targeted biopsies at 12 months after treatment. We evaluated the association between post-treatment mpMRI and PSA with disease persistence on the post-ablation biopsy. We also assessed post-treatment functional and oncological outcomes. RESULTS Median age was 69 years (Interquartile Range (IQR): 66-74) and median PSA was 6.9 ng/dL (IQR: 5.3-9.9). Of 19 men with persistent GG ≥ 2 disease, 58% (11 men) had no visible lesions on MRI. In the 14 men with PIRADS 4 or 5 lesions, 7 (50%) had either no cancer or GG 1 cancer at biopsy. Men with false negative mpMRI findings had higher PSA density (0.16 vs. 0.07 ng/mL2, P = 0.01). No change occurred in the mean Sexual Health Inventory for Men (SHIM) survey scores (17.0 at baseline vs. 17.7 post-treatment, P = 0.75) or International Prostate Symptom Score (IPSS) (8.1 at baseline vs. 7.7 at 24 months, P = 0.81) after treatment. CONCLUSIONS Persistent GG ≥ 2 cancer may occur after focal HIFU. mpMRI alone without confirmatory biopsy may be insufficient to rule out residual cancer, especially in patients with higher PSA density. Our study also validates previously published studies demonstrating preservation of urinary and sexual function after HIFU treatment.

Abstract
Afro-Caribbean men have a higher risk of prostate cancer than any other population of men
in the world. However, the Caribbean is composed of a heterogenous group of healthcare
systems located on small islands which makes population-based studies difficult to conduct
and interpret. The aim of this review is to compile previously published data on the state
of prostate cancer in Caribbean men and to highlight potential healthcare needs that can
be addressed by public health efforts. We reviewed three databases and identified relevant
papers that were subsequently searched by the authors. Peer-reviewed studies published in
the English language after 2010 with a focus on prostate cancer diagnosis, management, and
outcomes of Caribbean men were prioritized. Afro-Caribbean men were found to have a higher
incidence and mortality rate compared to their counterparts. Misperception about the
disease, lack of regional guidelines, and poor access to care are compounding factors that
result in worse outcomes for these men compared to high-income nations. Urologists and
oncologists in the region, while well-trained, are limited in number and in most cases do
not offer newer treatment modalities. Overall, only a few island nations have cancer
registries, and there remains a significant need for more population-based studies to
assess guideline adherence and outcomes. Until further research and investment in the
region is made, the disparity between the care received by Afro-Caribbean men and their
counterparts will likely remain.

Abstract
A multitude of studies have explored the role of artificial intelligence (AI) in providing diagnostic support to radiologists, pathologists, and urologists in prostate cancer detection, risk-stratification, and management. This review provides a comprehensive overview of relevant literature regarding the use of AI models in (1) detecting prostate cancer on radiology images (magnetic resonance and ultrasound imaging), (2) detecting prostate cancer on histopathology images of prostate biopsy tissue, and (3) assisting in supporting tasks for prostate cancer detection (prostate gland segmentation, MRI-histopathology registration, MRI-ultrasound registration). We discuss both the potential of these AI models to assist in the clinical workflow of prostate cancer diagnosis, as well as the current limitations including variability in training data sets, algorithms, and evaluation criteria. We also discuss ongoing challenges and what is needed to bridge the gap between academic research on AI for prostate cancer and commercial solutions that improve routine clinical care.

Abstract
BACKGROUND Average paternal age in the United States has increased substantially in the last few decades. Children of advanced age fathers have a higher incidence of early onset cancer and neuropsychiatric disease. OBJECTIVES To quantify the number of population adjusted cases of early-onset cancer and neuropsychiatric disease in children attributable to increasing paternal age in the United States. METHODS Paternal age in the United States from 1972 to 2015 was collected using the National Vital Statistics System (NVSS). Population attributable fraction and paternal age-specific cumulative incidence rates of several cancers and neuropsychiatric disorders were obtained from peer-reviewed publications. Paternal age-specific birth rates were correlated with paternal age-specific cumulative incidence rates to determine the number of attributable cases of disease caused by advancing age of fathers in the United States. RESULTS The 2015 birth cohort in the United States is estimated to expect 9.2% more cases of acute lymphoblastic leukemia (ALL) diagnosed before 16 years of age (157 additional cases), 13.2% more cases of embryonal tumors in children <5 years of age (209 additional cases), and 13.0% more cases of breast cancer in females younger than 40 years old (424 additional cases) compared to the 1972 birth cohort. We can estimate to expect 10.5% more cases of schizophrenia diagnosed before 21 years of age (2864 additional cases), 6.3% more cases of autism spectrum disorder (ASD) in adolescents <17 years of age (2934 additional cases), 4.5% more cases of anorexia nervosa (AN) in females 8-30 years old (620 additional cases), and 9.2% more cases of bipolar disorder in young patients 16-25 years old (252 additional cases) in the 2015 birth cohort compared to the 1972 birth cohort. CONCLUSION Increasing paternal age in the United States is associated with a substantial increase in the number of cases of early-onset cancer and neuropsychiatric disease in offspring.

Abstract
INTRODUCTION Bicycle seat pressure on the perineum may impair arousal and clitoral erection, likely contributing to genital pain and numbness experienced by female cyclists. AIM We aimed to identify the association between genital pain and numbness experienced by female cyclists and female sexual dysfunction (FSD). METHODS Female cyclists were recruited to complete an online survey using the Female Sexual Function Index (FSFI), a validated questionnaire to assess FSD. Cyclist demographics, experience, preferred riding style, use of ergonomic cycle modifications, and genital discomfort while riding were also queried. Multivariate logistic regression analysis was used to evaluate risk factors of FSD. MAIN OUTCOME MEASURES The main outcome was FSFI score, which is used to diagnose FSD when the FSFI score is <26.55. RESULTS Of the survey respondents, 178 (53.1%) completed the survey and FSFI questionnaire. Mean age was 48.1 years (±0.8 standard error [SE]), and the average riding experience was 17.1 years (±0.9 SE). Overall, 53.9% of female cyclists had FSD, 58.1% reported genital numbness, and 69.1% reported genital pain. After adjusting for age, body mass index, relationship status, smoking history, comorbidities, and average time spent cycling per week, females who reported experiencing genital numbness half the time or more were more likely to have FSD (adjusted odds ratio [aOR], 6.0; 95% CI, 1.5-23.6; P = .01), especially if localized to the clitoris (aOR, 2.5; 95% CI, 1.2-5.5; P = .02). Females that reported genital pain half the time or more while cycling also were more likely to have FSD (aOR, 3.6; 95% CI, 1.2-11.1; P = .02). Cyclists experiencing genital pain within the first hour of their ride were more likely to have FSD (aOR, 12.6; 95% CI, 2.5-63.1; P = .002). Frequency and duration of cycling were not associated with FSD. Analysis of FSFI domains found that the frequency of numbness was correlated with decreased arousal, orgasm, and satisfaction during intercourse, whereas the frequency of pain significantly reduced arousal, orgasm, and genital lubrication. CLINICAL IMPLICATIONS Female cyclists that experience numbness and/or pain have higher odds of reporting FSD. STRENGTHS & LIMITATIONS Our study includes a validated questionnaire to assess FSD and queries specific characteristics and symptoms of genital pain and genital numbness; however, the study is limited by its cross-sectional survey design. CONCLUSION This study highlights the need for cyclists to address genital pain and numbness experienced while cycling, and future studies are required to determine if alleviating these symptoms can reduce the impact of cycling on female sexual function.

Abstract
OBJECTIVE To evaluate the impact of advanced paternal age on maternal and perinatal outcomes in the United States. DESIGN Retrospective, population based cohort study. SETTING US. POPULATION 40 529 905 documented live births between 2007 and 2016. MAIN OUTCOME MEASURES Primary perinatal outcomes were gestational age, birth weight, Apgar score at five minutes, admission to a neonatal intensive care unit, need for postpartum antibiotics, and seizures. Primary maternal outcomes were gestational diabetes and pre-eclampsia. Secondary outcome was the number of preventable perinatal events. RESULTS Higher paternal age was associated with an increased risk of premature birth, low birth weight, and low Apgar score. After adjustment for maternal age, infants born to fathers aged 45 years or older had 14% higher odds of premature birth (odds ratio 1.14, 95% confidence interval 1.13 to 1.15), independent of gestational age, and 18% higher odds of seizures (1.18, 0.97 to 1.44) compared with infants of fathers aged 25 to 34 years. The odds of gestational diabetes was 34% higher (1.34, 1.29 to 1.38) in mothers with the oldest partners. 13.2% (95% confidence interval 12.5% to 13.9%) of premature births and 18.2% (17.5% to 18.9%) of gestational diabetes in births associated with older fathers were estimated to be attributable to advanced paternal age. CONCLUSIONS Advanced paternal age is associated with negative effects on both mothers and offspring. Given the relatively low prevalence of advanced paternal age in the US, population level impacts are currently modest. Nevertheless, as advanced paternal age has doubled in the US over the past generation, further investigation is warranted of the impact on birth outcomes and public health.

Abstract
The objective of the current study was to measure the adherence of guideline-based evaluation and treatment of hypogonadism by medical specialty. A retrospective review was performed analyzing patients from a single academic institution within the past 10 years. The cohort of 193 men was grouped according to medical specialty of the diagnosing physician (50 urology, 49 primary care, 44 endocrinology, and 50 HIV medicine). Adherence to guidelines was assessed using the Endocrine Society's criteria. Primary care patients were older compared to the rest of the cohort ( p < .001) but BMI and cardiovascular risk factors were similar ( p = .900). Patients treated by urologists and endocrinologists had the highest percentage of low testosterone findings at initial encounter at 72% ( p < .001). Sixty-two percent of urology patients had low LH or FSH compared to 63.6% for endocrinology and 16% for primary care ( p < .001). As for brain MRI findings, no urology patients had positive findings (0/9) while eight pituitary adenomas (40%) were found by endocrinologists. Forty-five percent of men treated by urologists received TRT without repeat confirmation, compared to 58% of endocrinologists, 77% of primary care, and 88% of HIV medicine ( p < .001). All urology patients had PSA checked before TRT compared to 77.5% of primary care and 61.2% of endocrinology patients ( p = .063). Adherence to the guidelines helps prevent undue over-diagnosis and over-treatment of hypogonadism. This study suggests that adherence to guideline-based screening is varied among specialties.

Abstract
BACKGROUND AND AIMS Chronic scrotal pain is a common yet poorly understood urologic disease. Current treatment paradigms are sub-optimal and include anti-inflammatory drugs and opioids as well as invasive surgical management such as microdenervation of the spermatic cord. In this study, the efficacy of external vibratory stimulation (EVS) was evaluated as an alternative treatment option for idiopathic scrotal pain. MATERIALS AND METHODS Ten consecutive patients presenting to an academic urology clinic between December 2016 and April 2017 with scrotal pain were prospectively enrolled. After a comprehensive history and physical exam, patients were presented with and oriented to a spherical vibratory device that they were instructed to use topically each day for four weeks. Average and maximum pain severity, frequency, and bother scores were tracked at 2-week intervals using a visual analog scale (0-10) via survey. Descriptive statistics facilitated interpretation of individual changes in pain. RESULTS Nine men, with a median age of 46 years, completed at least 2 weeks of the study intervention. 78% (7/9) of men achieved some improvement in daily scrotal pain levels. Overall, average pain decreased from 4.9 to 2.7 (p=0.009) while maximum pain severity decreased from 6.3 to 4.0 (p=0.013). The frequency of pain also decreased for 55.6% (5/9) of men. No severe side effects were noted by any of the participants though several patients reported mild paresthesia only during application of the device. The majority of men expressed interest in continuing treatment after conclusion of the study. CONCLUSION External vibratory stimulation has been suggested as a promising non-invasive tool to alleviate chronic pain. As a proof-of-concept, we implemented EVS to treat men with idiopathic orchialgia. The majority of patients noted benefit in both severity and frequency of pain. Given its low risk profile, EVS deserves further evaluation and inclusion in treatment guidelines as a promising experimental therapy for a disease with few conservative treatment options available to providers. IMPLICATIONS In this longitudinal study, external vibratory stimulation was found to decrease chronic scrotal pain without any adverse effects. The use of this non-invasive, non-pharmaceutical therapy to treat chronic scrotal pain has the potential to decrease physician and patient dependence on surgical procedures and opioid prescriptions. Future randomized, double blind clinical trials with a placebo arm are required to corroborate these findings and establish the true efficacy of EVS.

Abstract
IMPORTANCE Use of robotic surgery has increased in urological practice over the last decade. However, the use, outcomes, and costs of robotic nephrectomy are unknown. OBJECTIVES To examine the trend in use of robotic-assisted operations for radical nephrectomy in the United States and to compare the perioperative outcomes and costs with laparoscopic radical nephrectomy. DESIGN, SETTING, AND PARTICIPANTS This retrospective cohort study used the Premier Healthcare database to evaluate outcomes of patients who had undergone robotic-assisted or laparoscopic radical nephrectomy for renal mass at 416 US hospitals between January 2003 and September 2015. Multivariable regression modeling was used to assess outcomes. EXPOSURES Robotic-assisted vs laparoscopic radical nephrectomy. MAIN OUTCOMES AND MEASURES The primary outcome of the study was the trend in use of robotic-assisted radical nephrectomy. The secondary outcomes were perioperative complications, based on the Clavien classification system, and defined as any complication (Clavien grades 1-5) or major complications (Clavien grades 3-5, for which grade 5 results in death); resource use (operating time, blood transfusion, length of hospital stay); and direct hospital cost. RESULTS Among 23 753 patients included in the study (mean age, 61.4 years; men, 13 792 [58.1%]), 18 573 underwent laparoscopic radical nephrectomy and 5180 underwent robotic-assisted radical nephrectomy. Use of robotic-assisted surgery increased from 1.5% (39 of 2676 radical nephrectomy procedures in 2003) to 27.0% (862 of 3194 radical nephrectomy procedures) in 2015 (P for trend <.001). In the weighted-adjusted analysis, there were no significant differences between robotic-assisted and laparoscopic radical nephrectomy in the incidence of any (Clavien grades 1-5) postoperative complications (adjusted rates, 22.2% vs 23.4%, difference, -1.2%; 95% CI, -5.4 to 3.0%) or major (Clavien grades 3-5) complications (adjusted rates, 3.5% vs 3.8%, difference, -0.3%; 95% CI, -1.0% to 0.5%). The rate of prolonged operating time (>4 hours) for patients undergoing the robotic-assisted procedure was higher than for patients receiving the laparoscopic procedure in the adjusted analysis (46.3% vs 25.8%; risk difference, 20.5%; 95% CI, 14.2% to 26.8%). Robotic-assisted radical nephrectomy was associated with higher mean 90-day direct hospital costs ($19 530 vs $16 851; difference, $2678; 95% CI, $838 to $4519), mainly accounted for operating room ($7217 vs $5378; difference, $1839; 95% CI, $1050 to $2628) and supply costs ($4876 vs $3891; difference, $985; 95% CI, $473 to $1498). CONCLUSIONS AND RELEVANCE Among patients undergoing radical nephrectomy for renal mass between 2003 and 2015, the use of robotic-assisted surgery increased substantially. The use of robotic-assistance was not associated with increased risk of any or major complications but was associated with prolonged operating time and higher hospital costs compared with laparoscopic surgery.

Abstract
PURPOSE Partial nephrectomy (PN) remains underutilized within the United States and few reports have attempted to explain this trend. The aim of this study is to evaluate the nationwide incidence of unsuccessful PN and factors that predict its occurrence. METHODS Using the Premier Healthcare Database, we retrospectively analyzed a weighted sample of 66,432 patients undergoing curative surgery for renal mass between 2003 and 2015. PN intent was denoted by presence of insurance claims for the administration of mannitol. Unsuccessful PN was defined as an event in which patients were administered mannitol but received radical nephrectomy. A multivariate logistic regression model was generated to identify factors predicting unsuccessful PN. RESULTS Overall rates of unsuccessful PN declined from 33.5% to 14.5% since 2003. Conversion to radical nephrectomy occurred most frequently during laparoscopic (34.7%) and least frequently during robotic approach (13.6%). There was significant difference in the rate of unsuccessful PN between very high and very low volume surgeons (open: 39.4% vs. 13.3%, laparoscopic: 51.2% vs. 32.2%, and robot assisted: 27.1% vs. 9.4%, all P<0.001). After adjustment for patient- and hospital-related factors, surgical approach (laparoscopic vs. open, odds ratio = 1.74, 95% CI: 1.31-2.30, P<0.001) and annual surgeon volume (very high vs. very low, odds ratio = 0.27, 95% CI: 0.21-0.34 P<0.001) were associated with unsuccessful PN. CONCLUSIONS Although the rate of unsuccessful PN appears to be declining, it still remains common for low volume surgeons and with the laparoscopic surgical approach. Further evaluation of its effect on health care outcomes is necessary.

Abstract
CONTEXT The recent evolution of management options for urolithiasis has presented a unique dilemma for the modern urologist. A comprehensive understanding of epidemiological trends along with current provider preferences in treating urinary stones would be beneficial. OBJECTIVE To review trends in the prevalence, treatments, and costs of urolithiasis worldwide. EVIDENCE ACQUISITION A literature review was performed using the MEDLINE database, the Cochrane Library Central search facility, Web of Science, and Google Scholar between 1986 and 2016. Keywords used for the search were "urolithiasis" and "prevalence; treatment; and cost". EVIDENCE SYNTHESIS The incidence and prevalence of urinary stones are rising around the world, including regions that have historically had low rates of urolithiasis. Common theories explaining this trend involve climate warming, dietary changes, and obesity. Shockwave lithotripsy (SWL) has been the preferred mode of treatment since its introduction in the 1980s. However, ureteroscopy (URS) has become increasingly popular for small stones regardless of location because of lower recurrence rates and costs. Developing countries have been slower to adopt URS technology and continue to use percutaneous nephrolithotomy at a steady rate. CONCLUSIONS URS has recently challenged SWL as the treatment modality preferred for small upper urinary tract stones. In some cases it is less expensive but still highly effective. As the burden of stone disease increases worldwide, appropriate selection of stone removal therapies will continue to play an important role and will thus require further investigation. PATIENT SUMMARY Urinary stones are becoming more prevalent. Recent advances in technology have improved the management of this disease and have decreased costs.

Abstract
STUDY OBJECTIVE We describe the availability of preventive health services in US emergency departments (EDs), as well as ED directors' preferred service and perceptions of barriers to offering preventive services. METHODS Using the 2007 National Emergency Department Inventory (NEDI)-USA, we randomly sampled 350 (7%) of 4,874 EDs. We surveyed directors of these EDs to determine the availability of (1) screening and referral programs for alcohol, tobacco, geriatric falls, intimate partner violence, HIV, diabetes, and hypertension; (2) vaccination programs for influenza and pneumococcus; and (3) linkage programs to primary care and health insurance. ED directors were asked to select the service they would most like to implement and to rate 5 potential barriers to offering preventive services. RESULTS Two hundred seventy-seven EDs (80%) responded across 46 states. Availability of services ranged from 66% for intimate partner violence screening to 19% for HIV screening. ED directors wanted to implement primary care linkage most (17%) and HIV screening least (2%). ED directors "agreed/strongly agreed" that the following are barriers to ED preventive care: cost (74%), increased patient length of stay (64%), lack of follow-up (60%), resource shifting leading to worse patient outcomes (53%), and philosophical opposition (27%). CONCLUSION Most US EDs offer preventive services, but availability and ED director preference for type of service vary greatly. The majority of EDs do not routinely offer Centers for Disease Control and Prevention-recommended HIV screening. Most ED directors are not philosophically opposed to offering preventive services but are concerned with added costs, effects on ED operations, and potential lack of follow-up.
