Laparoscopic Nephroureterectomy: The Distal Ureteral Dilemma

Transitional cell carcinoma affecting the upper urinary tract, though uncommon, constitutes a serious urologic disease. Radical nephroureterectomy remains the treatment of choice but has undergone numerous modifications over the years. Although the standard technique has not been defined, the laparoscopic approach has gained in popularity in the last two decades. The most appropriate oncological management of the distal ureteral and bladder cuff has been a subject of much debate. The aim of the nephroureterectomy procedure is to remove the entire ipsilateral upper tract in continuity while avoiding extravesical transfer of tumor-containing urine during bladder surgery. A myriad of technical modifications have been described. In this article, we review the literature and present an overview of the options for dealing with the lower ureter during radical nephroureterectomy

Development Methodology of the Novel Endoscopic Stone Treatment Step 2/A Training/Assessment Curriculum and a Roadmap on Developing Hands-on Training Curriculums in Future: An International Collaborative Work by European Association of Urology Sections

Background: Basic simulation training in endourology was established with the endoscopic stone treatment step 1 (EST-s1), which is now recognized worldwide for training and examination. Following on from EST-s1, the endoscopic stone treatment step 2 (EST-s2) was started by the European Association of Urology (EAU) sections. Objective: We describe the methodology used in the development of EST-s2 assessment curriculum. Materials and Methods: The "full-life cycle curriculum development" template was followed for curriculum development, focusing on intermediate training of EST protocol with complex endourologic tasks. A cognitive task analysis (CTA) was run in accordance with EAU Urolithiasis guidelines. The protocol and its details underwent a first consensus by Delphi method with EAU Urolithiasis Section experts in March 2017. Once the outcome and metrics were decided, curriculum development was carried out. Purpose-built stones were developed, and simulator system requirement was defined. Preliminary testing was done in European Urology Residents Education Programme 2019 and in phase five the protocol was finalized with full tutor instruction sheet. Results: The EST-s2/A curriculum development took 38 months and involved EAU Uro-technology and urolithiasis sections with coordination from the European School of Urology training group. Starting from the initial CTA, a 1277-word revision with preliminary task description was produced. Nine intermediate skills were identified and included in the final training protocol. The training content and session evaluations were carried out by 26 experts and 16 final year trainees, respectively. Although the experts agreed that EST-s2/A protocol was well structured (96%), covered the complex endourologic maneuvers (92%), and was useful to optimize and improve hands-on-training (HoT) sessions (92%), the overall evaluation was scored 4.25/5 by trainees. Conclusion: We describe the development methodology for intermediate EST curriculum, which also provides a roadmap on developing other HoT protocols in future. Patients Summary: In this report we described the development of the novel intermediate training curriculum for EST, called EST-s2, which took 3 years of collaborative work inside the EAU. This article is aimed to strengthen the standards in curriculum development and clearly describe the background of this new EAU official endourology protocol

Evaluation of a remote-controlled laparoscopic camera holder for basic laparoscopic skills acquisition : a randomized controlled trial

Unsteady camera movement and poor visualization contribute to a difficult learning curve for laparoscopic surgery. Remote-controlled camera holders (RCHs) aim to mitigate these factors and may be used to overcome barriers to learning. Our aim was to evaluate performance benefits to laparoscopic skill acquisition in novices using a RCH. Novices were randomized into groups using a human camera assistant (HCA) or the FreeHand v1.0 RCH and trained in the (E-BLUS) curriculum. After completing training, a surgical workload questionnaire (SURG-TLX) was issued to participants. Forty volunteers naïve in laparoscopic skill were randomized into control and intervention groups (n = 20) with intention-to-treat analysis. Each participant received up to 10 training sessions using the E-BLUS curriculum. Competency was reached in the peg transfer task in 5.5 and 7.6 sessions for the ACH and HCA groups, respectively (P = 0.015), and 3.6 and 6.8 sessions for the laparoscopic suturing task (P = 0.0004). No significance differences were achieved in the circle cutting (P = 0.18) or needle guidance tasks (P = 0.32). The RCH group experienced significantly lower workload (P = 0.014) due to lower levels of distraction (P = 0.047). Remote-controlled camera holders have demonstrated the potential to significantly benefit intra-operative performance and surgical experience where camera movement is minimal. Future high-quality studies are needed to evaluate RCHs in clinical practice. ISRCTN 8373397

The european urology residents education programme hands-on training format: 4 years of hands-on training improvements from the European School of Urology

Background: The European School of Urology (ESU) started the European Urology Residents Education Programme (EUREP) in 2003 for final year urology residents, with hands-on training (HOT) added later in 2007. Objective: To assess the geographical reach of EUREP, trainee demographics, and individual quality feedback in relation to annual methodology improvements in HOT. Design, setting, and participants: From September 2014 to October 2017 (four EUREP courses) several new features have been applied to the HOT format of the EUREP course: 1:1 training sessions (2015), fixed 60-min time slots (2016), and standardised teaching methodology (2017). The resulting EUREP HOT format was verified by collecting and prospectively analysing the following data: total number of participants attending different HOT courses; participants’ age; country of origin; and feedback obtained annually. Results and limitations: A total of 796 participants from 54 countries participated in 1450 HOT sessions over the last 4 yr. This included 294 (20%) ureteroscopy (URS) sessions, 237 (16.5%) transurethral resection (TUR) sessions, 840 (58%) basic laparoscopic sessions, and 79 (5.5%) intermediate laparoscopic sessions. While 712 residents (89%) were from Europe, 84 (11%) were from non-European nations. Of the European residents, most came from Italy (16%), Germany (15%), Spain (15%), and Romania (8%). Feedback for the basic laparoscopic session showed a constant improvement in scores over the last 4 yr, with the highest scores achieved last year. This included feedback on improvements in tutor rating (p = 0.017), organisation (p < 0.001), and personal experience with EUREP (p < 0.001). Limitations lie in the difficulties associated with the use of an advanced training curriculum with wet laboratory or cadaveric courses in this format, although these could be performed in other training centres in conjunction with EUREP. Conclusions: The EUREP trainee demographics show that the purpose of the course is being achieved, with excellent feedback reported. While European trainees dominate the demographics, participation from a number of non-European countries suggests continued ESU collaboration with other national societies and wider dissemination of simulation training worldwide.EUREP is supported by educational grant from Olympus.info:eu-repo/semantics/acceptedVersio

Discrimination, Reliability, Sensitivity, and Specificity of Robotic Surgical Proficiency Assessment With Global Evaluative Assessment of Robotic Skills and Binary Scoring Metrics: Results From a Randomized Controlled Trial

Objective: To compare binary metrics and Global Evaluative Assessment of Robotic Skills (GEARS) evaluations of training outcome assessments for reliability, sensitivity, and specificity. Background: GEARS–Likert-scale skills assessment are a widely accepted tool for robotic surgical training outcome evaluations. Proficiency-based progression (PBP) training is another methodology but uses binary performance metrics for evaluations. Methods: In a prospective, randomized, and blinded study, we compared conventional with PBP training for a robotic suturing, knot-tying anastomosis task. Thirty-six surgical residents from 16 Belgium residency programs were randomized. In the skills laboratory, the PBP group trained until they demonstrated a quantitatively defined proficiency benchmark. The conventional group were yoked to the same training time but without the proficiency requirement. The final trial was video recorded and assessed with binary metrics and GEARS by robotic surgeons blinded to individual, group, and residency program. Sensitivity and specificity of the two assessment methods were evaluated with area under the curve (AUC) and receiver operating characteristics (ROC) curves. Results: The PBP group made 42% fewer objectively assessed performance errors than the conventional group (P &lt; 0.001) and scored 15% better on the GEARS assessment (P = 0.033). The mean interrater reliability for binary metrics and GEARS was 0.87 and 0.38, respectively. Binary total error metrics AUC was 97% and for GEARS 85%. With a sensitivity threshold of 0.8, false positives rates were 3% and 25% for, respectively, the binary and GEARS assessments. Conclusions: Binary metrics for scoring a robotic VUA task demonstrated better psychometric properties than the GEARS assessment. </jats:sec

Cellular Angiofibroma of the Prostate: A Rare Tumor in an Unusual Location

We report the unusual occurrence of a cellular angiofibroma in prostatic tissue. In this case, a 84-year-old man presented in the emergency room with urinary retention. Ultrasound revealed an enlarged prostate, which was suggestive for benign prostatic hyperplasia. The patient was treated with a Millin retropubic prostatectomy. Macroscopically the prostate contained multiple circumscribed nodules. Microscopic examination of the tumor showed the appearance of cellular angiofibroma, consisting of bland spindle cells and prominent, hyalinized vessels. The diagnosis was supported by FISH, which revealed monoallelic loss of RB1/13q14 region, as seen in spindle cell lipoma, (extra-) mammary myofibroblastoma, and cellular angiofibroma. Cellular angiofibromas are rare, benign soft tissue tumours and were never reported in the prostatic gland
