AB  - OBJECTIVE: To validate the Advanced Scope Trainer (AST; Mediskills, Northampton, 
      UK). The AST is a currently unvalidated simulator, developed for flexible 
      ureterorenoscopy (fURS) training. This study aims to assess the face, content, 
      construct, and concurrent validity to assess the level of transferability of 
      skills to the operating room. MATERIALS AND METHODS: This prospective, 
      observational, and comparative study recruited novices (n = 19) and trainees 
      (n = 34), with participants performing a diagnostic fURS, followed by removal of 
      a lower pole stone, on the AST. Fifteen participants performed a fURS on fresh 
      frozen cadavers to assess concurrent validity. Trainees were supervised by expert 
      urologists (n = 7) during each procedure. Performance was evaluated using the 
      validated Objective Structured Assessment of Technical Skills (OSATS) assessment. 
      Face and content validity were demonstrated by anonymous surveys from 
      participants and faculty. RESULTS: Face validity assessment revealed that 
      trainees found the simulator was 76% realistic (3.8/5 on a Likert scale). Laser 
      stone fragmentation (4.11 +/- 0.85) and manual stone extraction (4.03 +/- 0.85) were 
      thought to be the most realistic components and guidewire insertion (3.14 +/- 1.35) 
      the least. Participants also believed the simulator to be useful, giving 
      transferrable skills to take into the operating room, demonstrating content 
      validity. Using an OSATS assessment, concurrent validity was demonstrated in 
      "respect for tissue" (P = .0105) and "time and motion" (P = .0196). Construct 
      validity was also demonstrated when comparing novices to trainees (mean OSATS 
      10.11 +/- 2.28 vs 23.89 +/- 5.38). CONCLUSION: This study has demonstrated face, 
      content, construct, and concurrent validity of the AST for fURS training. Further 
      evaluation is necessary to demonstrate construct and predictive validity of 
      skills gained using the model.
