TRUSTED: The Paired 3D Transabdominal Ultrasound and CT Human Data for Kidney Segmentation and Registration Research

Inter-modal image registration (IMIR) and image segmentation with abdominal Ultrasound (US) data has many important clinical applications, including image-guided surgery, automatic organ measurement and robotic navigation. However, research is severely limited by the lack of public datasets. We propose TRUSTED (the Tridimensional Renal Ultra Sound TomodEnsitometrie Dataset), comprising paired transabdominal 3DUS and CT kidney images from 48 human patients (96 kidneys), including segmentation, and anatomical landmark annotations by two experienced radiographers. Inter-rater segmentation agreement was over 94 (Dice score), and gold-standard segmentations were generated using the STAPLE algorithm. Seven anatomical landmarks were annotated, important for IMIR systems development and evaluation. To validate the dataset's utility, 5 competitive Deep Learning models for automatic kidney segmentation were benchmarked, yielding average DICE scores from 83.2% to 89.1% for CT, and 61.9% to 79.4% for US images. Three IMIR methods were benchmarked, and Coherent Point Drift performed best with an average Target Registration Error of 4.53mm. The TRUSTED dataset may be used freely researchers to develop and validate new segmentation and IMIR methods.Comment: Alexandre Hostettler, and Toby Collins share last authorshi

Training centers: An essential step to developing skills in urolaparoscopy

Choosing laparoscopy is an important investment for urologists, and it must be learned from basic principles to advance skills through a steep learning curve; the caseload is made of frequent but very demanding procedures. In training centers, scholars are confronted with real-life conditions through large animal models. For about 1500 urologists, the European Institute of Tele Surgery has offered such a program for a decade. We evaluate its impact through a self-administered, Internet-hosted questionnaire. Individual data concern number and type of courses attended, skill level and type of practice before training, and expectations at registration. Personal benefit is evaluated through the delay before starting routine laparoscopy or the major procedures volume facing open counterparts. The ability of this program to meet scholar's expectations is reflected by eventual need for further training or by trainee suggestions. In spite of 85% cumulated satisfaction index, further developments must improve practical training: clear, reproducible stepwise protocols, repeated under supervision in animal models today and hopefully in augmented reality simulators tomorrow. The knowledge transfer and companionship made of theoretical and practical lessons followed by a straight supervised application represent an essential model for gaining proficiency. © 2009 Current Medicine Group, LLC References and Recommended Reading.SCOPUS: ar.jinfo:eu-repo/semantics/publishe

EAU Policy on Live Surgery Events

Item does not contain fulltextCONTEXT: Live surgery is an important part of surgical education, with an increase in the number of live surgery events (LSEs) at meetings despite controversy about their real educational value, risks to patient safety, and conflicts of interest. OBJECTIVE: To provide a European Association of Urology (EAU) policy on LSEs to regulate their organisation during urologic meetings. EVIDENCE ACQUISITION: The project was carried out in phases: a systematic literature review generating key questions, surveys sent to Live Surgery Panel members, and Internet- and panel-based consensus finding using the Delphi process to agree on and formulate a policy. EVIDENCE SYNTHESIS: The EAU will endorse LSEs, provided that the EAU Code of Conduct for live surgery and all organisational requirements are followed. Outcome data must be submitted to an EAU Web-based registry and complications reported using the revised Martin criteria. Regular audits will take place to evaluate compliance as well as the educational role of live surgery. CONCLUSIONS: This policy represents the consensus view of an expert panel established to advise the EAU. The EAU recognises the educational role of live surgery and endorses live case demonstration at urologic meetings that are conducted within a clearly defined regulatory framework. The overriding principle is that patient safety must take priority over all other considerations in the conduct of live surgery. PATIENT SUMMARY: Controversy exists regarding the true educational value of live surgical demonstrations on patients at surgical meetings. An EAU committee of experts developed a policy on how best to conduct live surgery at urologic meetings. The key principle is to ensure safety for every patient, including a code of conduct and checklist for live surgery, specific rules for how the surgery is organised and performed, and how each patient's results are reported to the EAU.

Development of a standardised training curriculum for robotic surgery: a consensus statement from an international multidisciplinary group of experts

International audienceOBJECTIVES:To explore the views of experts about the development and validation of a robotic surgery training curriculum, and how this should be implemented.MATERIALS AND METHODS:An international expert panel was invited to a structured session for discussion. The study was of a mixed design, including qualitative and quantitative components based on focus group interviews during the European Association of Urology (EAU) Robotic Urology Section (ERUS) (2012), EAU (2013) and ERUS (2013) meetings. After introduction to the aims, principles and current status of the curriculum development, group responses were elicited. After content analysis of recorded interviews generated themes were discussed at the second meeting, where consensus was achieved on each theme. This discussion also underwent content analysis, and was used to draft a curriculum proposal. At the third meeting, a quantitative questionnaire about this curriculum was disseminated to attendees to assess the level of agreement with the key points.RESULTS:In all, 150 min (19 pages) of the focus group discussion was transcribed (21 316 words). Themes were agreed by two raters (median agreement κ 0.89) and they included: need for a training curriculum (inter-rater agreement κ 0.85); identification of learning needs (κ 0.83); development of the curriculum contents (κ 0.81); an overview of available curricula (κ 0.79); settings for robotic surgery training ((κ 0.89); assessment and training of trainers (κ 0.92); requirements for certification and patient safety (κ 0.83); and need for a universally standardised curriculum (κ 0.78). A training curriculum was proposed based on the above discussions.CONCLUSION:This group proposes a multi-step curriculum for robotic training. Studies are in process to validate the effectiveness of the curriculum and to assess transfer of skills to the operating room
