ABSTRACT
PURPOSE
To determine web‐based public interest in minimally invasive surgery (MIS) specifically for urological oncological surgical procedures and how interest in robotics and laparoscopy ...compares over time.
MATERIALS AND METHODS
Worldwide search‐engine trend analysis included electronic Google queries of MIS urologic options from January 2004 to August 2019, worldwide. Join‐point regression was performed. Comparison of annual relative search volume (ARSV) and average annual percentage change (AAPC) were analysed to assess loss or gain of interest. Evaluations were made regarding 1) penetrance of interest for MIS in Urology; 2) how MIS urologic procedures compared over time; and 3) which were the top related queries to searches for urologic oncology procedures.
RESULTS
Increased interest was found for all of the MIS procedures evaluated. Mean ARSV for robotic approach was higher for the search term 'prostatectomy” (44.8 vs. 13.5; p < 0.001) and 'partial nephrectomy” (27.1 vs.11.5; p = 0.02). No statistical difference was found for the search terms 'cystectomy” or 'nephrectomy”. The analysis of mean (∆‐ARSV) of MIS procedures measured between the first and last 12 months of the study period showed an increased interest with a more pronounced ∆‐ARSV for robotic procedures. The top related searches for all surgical procedures were examined showing an increasing inquisitiveness with regards of type of urological cancers, treatment options, type of surgery and prognostic outcomes.
CONCLUSIONS
People are increasingly searching the web for MIS urological procedures. A growing appeal for robotics is demonstrated, especially for prostatectomy and partial nephrectomy where the robotic approach is gaining traction, suggesting a shift in mind‐set amongst people seeking urological healthcare information.

The diagnosis of functional neurological disorder (FND) relies on the demonstration of positive symptoms and signs, as supported by recent changes in DSM5. We recorded the findings of routine ...clinical eye movement assessment in 101 consecutive new patients with FND. Clinical examination triggered facial and eye movement disorders in 46% of patients, all with positive characteristics of functional movement disorder. These are useful as supporting features in making a positive diagnosis of FND.

BACKGROUND:Few studies have analyzed the tangible impact of global, philanthropic medical missions. We used qualitative methods to analyze the work of one such mission, Operation Walk Boston, which ...has made yearly trips to a Dominican Republic hospital since 2008.
METHODS:We interviewed twenty-one American and Dominican participants of the Operation Walk Boston team to investigate how the program led to changes at the host Dominican hospital and how the experience caused both mission protocols and U.S. practices to change. Transcripts were analyzed with the use of content analysis.
RESULTS:Participants noted that Operation Walk Boston’s technical knowledge transfer and managerial examples led to sustainable changes at the Dominican hospital. Additionally, participants observed an evolution in nursing culture, as the program inspired greater independence in decision-making. Participants also identified barriers such as language and organizational hierarchy that may limit bidirectional knowledge transfer. U.S. participants noted that their practices at home changed as a result of better appreciation for different providers’ roles and for managing cost in a resource-constrained environment.
CONCLUSIONS:Operation Walk Boston catalyzed sustainable changes in the Dominican hospital. Cultural norms and organizational structure are important determinants of program sustainability.
Abstract
The objective of this study was to compare transperineal (TP) versus transrectal (TR) magnetic resonance imaging (MRI) and transrectal ultrasound (TRUS) fusion prostate biopsy (PBx). ...Consecutive men who underwent prostate MRI followed by a systematic biopsy. Additional target biopsies were performed from Prostate Imaging Reporting & Data System (PIRADS) 3–5 lesions. Men who underwent TP PBx were matched 1:2 with a synchronous cohort undergoing TR PBx by PSA, Prostate volume (PV) and PIRADS score. Endpoint of the study was the detection of clinically significant prostate cancer (CSPCa; Grade Group ≥ 2). Univariate and multivariable analyses were performed. Results were considered statistically significant if p < 0.05. Overall, 504 patients met the inclusion criteria. A total of 168 TP PBx were pair-matched to 336 TR PBx patients. Baseline demographics and imaging characteristics were similar between the groups. Per patient, the CSPCa detection was 2.1% vs 6.3% (p = 0.4) for PIRADS 1–2, and 59% vs 60% (p = 0.9) for PIRADS 3–5, on TP vs TR PBx, respectively. Per lesion, the CSPCa detection for PIRADS 3 (21% vs 16%; p = 0.4), PIRADS 4 (51% vs 44%; p = 0.8) and PIRADS 5 (76% vs 84%; p = 0.3) was similar for TP vs TR PBx, respectively. However, the TP PBx showed a longer maximum cancer core length (11 vs 9 mm; p = 0.02) and higher cancer core involvement (83% vs 65%; p < 0.001) than TR PBx. Independent predictors for CSPCa detection were age, PSA, PV, abnormal digital rectal examination findings, and PIRADS 3–5. Our study demonstrated transperineal MRI/TRUS fusion PBx provides similar CSPCa detection, with larger prostate cancer core length and percent of core involvement, than transrectal PBx.

Purpose We quantified prostate swelling and the intraprostatic point shift during high intensity focused ultrasound using real-time ultrasound. Materials and Methods The institutional review board ...approved this retrospective study. Whole gland high intensity focused ultrasound was done in 44 patients with clinically localized prostate cancer. Three high intensity focused ultrasound sessions were required to cover the entire prostate, including the anterior zone (session 1), middle zone (session 2) and posterior zone (session 3). Computer assisted 3-dimensional reconstructions based on 3 mm step-section images of intraoperative transrectal ultrasound were compared before and after each session. Results Most prostate swelling and intraprostatic point shifts occurred during session 1. The median percent volume increase was 18% for the transition zone, 9% for the peripheral zone and 13% for the entire prostate. The volume percent increase in the transition zone (p <0.001), peripheral zone (p = 0.001) and entire prostate (p = 0.001) statistically depended on the volume of each area measured preoperatively. The median 3-dimensional intraprostatic shift was 3.7 mm (range 0.9 to 13) in the transition zone and 5.5 mm (range 0.2 to 14) in the peripheral zone. A significant negative linear correlation was found between the preoperative presumed circle area ratio, and the percent increase in prostate volume (p = 0.001) and shift (p = 0.01) during high intensity focused ultrasound. Conclusions We quantified significant prostate swelling and shift during high intensity focused ultrasound. Smaller prostates and a smaller preoperative presumed circle area ratio were associated with greater prostate swelling and intraprostatic shifts. Real-time intraoperative adjustment of the treatment plan impacts the achievement of precise targeting during high intensity focused ultrasound, especially in prostates with a smaller volume and/or a smaller preoperative presumed circle area ratio.
Abstract Background Level II–III inferior vena cava (IVC) tumor thrombectomy for renal cell carcinoma is among the most challenging urologic oncologic surgeries. In 2015, we reported the initial ...series of robot-assisted level III caval thrombectomy. Objective To describe our University of Southern California technique in a step-by-step fashion for robot-assisted IVC level II–III tumor thrombectomy. Design, setting, and participants Twenty-five selected patients with renal neoplasm and level II–III IVC tumor thrombus underwent robot-assisted surgery with a minimum 1-yr follow-up (July 2011 to March 2015). Surgical procedure Our standardized anatomic-based “IVC-first, kidney-last” technique for robot-assisted IVC thrombectomy focuses on minimizing the chances of an intraoperative tumor thromboembolism and major hemorrhage. Outcome measurements and statistical analysis Baseline demographics, pathology data, 90-d and 1-yr complications, and oncologic outcomes at last follow-up were assessed. Results and limitations Robot-assisted IVC thrombectomy was successful in 24 patients (96%) (level III: n = 11; level II: n = 13); one patient was electively converted to open surgery for failure to progress. Median data included operative time of 4.5 h, estimated blood loss was 240 ml, hospital stay 4 d; five patients (21%) received intraoperative blood transfusion. All surgical margins were negative. Complications occurred in four patients (17%): two were Clavien 2, one was Clavien 3a, and one was Clavien 3b. All patients were alive at a 16-mo median follow-up (range: 12–39 mo). Conclusions Robotic IVC tumor thrombectomy is feasible for level II–III thrombi. To maximize intraoperative safety and chances of success, a thorough understanding of applied anatomy and altered vascular collateral flow channels, careful patient selection, meticulous cross-sectional imaging, and a highly experienced robotic team are essential. Patient summary We present the detailed operative steps of a new minimally invasive robot-assisted surgical approach to treat patients with advanced kidney cancer. This type of surgery can be performed safely with low blood loss and excellent outcomes. Even patients with advanced kidney cancer could now benefit from robotic surgery with a quicker recovery.
