A novel nomogram to predict testicular torsion in children with acute scrotal pain: a single-center retrospective study in western China

Acute scrotal pain (ASP) is the most common urological emergency in pediatrics, and its causes include testicular torsion (TT), testicular appendage torsion, and epididymo-orchitis. Among them, TT requires prompt and accurate diagnosis and urgent surgical exploration to prevent testicular loss. Conservative anti-infective treatment is recommended for epididymo-orchitis, and surgery is considered only when scrotal abscess formation and sepsis occur. Improving the understanding of TT in primary care doctors, early diagnosis, and timely surgical exploration are essential to improve the survival rate of TT and avoid excessive treatment. This study aimed to explore the risk factors for TT in children with ASP and construct a predictive model.
