Missing Information Details:
- Sample size used for the test set and the data provenance: This information is not provided in the document. The studies were non-clinical bench tests and biocompatibility tests, not clinical trials with patient data.
- Number of experts used to establish the ground truth for the test set and the qualifications of those experts: This is not applicable as the studies were non-clinical bench tests and material safety tests, not studies requiring expert interpretation of clinical images or data.
- Adjudication method (e.g. 2+1, 3+1, none) for the test set: Not applicable for non-clinical bench tests.
- If a multi-reader multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance: Not applicable. This document describes a medical instrument, not an AI-enabled device.
- If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable. This is not an AI algorithm.

The LumiRex Single-Use Digital Flexible Ureteroscope is a single-use video endoscope designed for use with Contra Healthcare Solutions video processors, urology accessories, and other ancillary equipment used in urology and urological procedures.
The LumiRex Single-Use Ureteroscope is a flexible video-based medical device designed for insertion through the urethra into the urinary tract. It comprises a long, thin tube equipped with a light source and a camera to provide real-time visualization of the urinary tract and interior of the kidney. The ureteroscope also features a working channel that allows for installation of fluids, the passage of various instruments, such as biopsy forceps, cytology brushes, biopsy brushes, and stone retrieval baskets to facilitate urology and ureteroscopy procedures.
The ureteroscope can be used wired or wireless through a Wireless Scope Adapter or Wired Scope Adapter. The adapters transmit images from the ureteroscope to the Video Processor Unit where the user can view the image from the ureteroscope, control the LED, and save and export images from the ureteroscope onto USB removable media.
The provided FDA 510(k) Clearance Letter for the LumiRex Ureteroscope does not detail a clinical study with acceptance criteria and device performance in the way typically expected for an AI/software as a medical device (SaMD) clearance. The document focuses on hardware aspects of the ureteroscope, such as sterilization, biocompatibility, electrical safety, and basic bench testing (e.g., field of view, depth of field, image quality).
Specifically, there is no mention of an AI component, an algorithm, or any study involving human readers or ground truth for diagnostic accuracy. The "Software" section primarily refers to verification and validation of the device's operating software (e.g., for image processing, LED control) according to IEC 62304, not an AI or diagnostic algorithm.
Therefore, I cannot fulfill the request to describe the acceptance criteria and study that proves the device (in the context of an AI/diagnostic algorithm) meets acceptance criteria, an MRMC study, or the establishment of ground truth for a diagnostic task. The document provided does not contain this information.
Based on the provided text, the LumiRex Ureteroscope is a physical medical device (endoscope) and not an AI/SaMD product that would typically involve the type of diagnostic performance studies you are asking about.
To answer your prompt with the available information:
Acceptance Criteria and Device Performance for LumiRex Ureteroscope (as per 510(k) Summary)
Based on the provided FDA 510(k) Premarket Notification (K243532) for the LumiRex Ureteroscope, the "acceptance criteria" and "study" described are primarily focused on the physical and functional performance of the medical device itself, rather than the diagnostic performance of an AI algorithm. The rigorous detail for AI/diagnostic studies (e.g., sample size for test set, number of experts, adjudication methods, MRMC studies) is not present because this is not an AI-driven diagnostic device.
The clearance is for a ureteroscope, which is a tool for visualization and intervention. Its performance is evaluated against engineering standards and comparison to a predicate device, not against clinical diagnostic accuracy metrics established by human experts reading images with or without AI assistance.
Here's an interpretation of the "acceptance criteria" and "reported device performance" based on the document, framed by the categories you requested, but noting where information is absent due to the nature of the device:
