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).\n\nTesticular 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.\n\nCurrent 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.\n\nThe main questions the study aims to answer are:\n\n* Part 1 (Feasibility study, n=24) Can SR-NIRS reliably collect usable measurements in healthy children?\n* Part 2 (exploratory study, n=50): Do SR-NIRS measurements differ between children with and without torsion?\n\nParticipants will:\n\n* Have a small probe placed on the skin over the testicle(s) and thigh\n* Undergo a brief measurement during a single visit\n\nThis study will not affect diagnosis or treatment. The results will help guide future research.",[28,29],"Testicular Torsion","Healthy",[31,32,33,34],"Feasibility study","Exploratory Study","Near-infrared spectroscopy","Pediatric Urology","NOT_YET_RECRUITING","2026-04-20",{"date":38,"type":39},"2026-04-23","ACTUAL",{"date":41,"type":22},"2026-09-01",{"date":43,"type":22},"2029-09-01",{"name":45,"class":46},"Kourosh Afshar","OTHER",""]
