Light-Based Monitoring (SR-NIRS) for Suspected Testicular Torsion in Children

简要摘要

The goal of this clinical trial is to learn whether a non-invasive light-based test called Spatially Resolved Near-Infrared Spectroscopy (SR-NIRS) can measure blood flow and oxygen levels in the testicles of children. The study includes boys aged 1 month to 18 years, including those without testicular problems (part 1) and those with sudden scrotal pain (part 2). Testicular torsion is a condition where the blood supply to the testicle becomes twisted and reduced. This can lead to permanent damage if not treated quickly. Current methods, such as ultrasound or surgery, may not always be immediately available and can sometimes lead to delays or unnecessary procedures. This study explores whether SR-NIRS can provide useful information about blood flow and oxygen levels in painful testicles of the children. The main questions the study aims to answer are: * Part 1 (Feasibility study, n=24) Can SR-NIRS reliably collect usable measurements in healthy children? * Part 2 (exploratory study, n=50): Do SR-NIRS measurements differ between children with and without torsion? Participants will: * Have a small probe placed on the skin over the testicle(s) and thigh * Undergo a brief measurement during a single visit This study will not affect diagnosis or treatment. The results will help guide future research.
