Rotation of the testis around the axis of the spermatic cord results in tissue ischaemia and testicular torsion (TT). TT in the newborn infant in the 1st month of life is referred to as neonatal TT (NTT) or perinatal TT and occurs in 6.1/100, 000 live births. The true incidence could be higher as some of these occur prenatally and can be asymptomatic. TT can be extravaginal, intravaginal and mesorchial and NTT is usually extravaginal. Physical examination can be adequate for the diagnosis, and utility of ultrasound (US) is mainly to exclude other conditions. If the timing of the torsion is prenatal, the testicle may not be salvageable. But, in certain situations, these could be asymptomatic bilateral TT. When the timing of torsion is not simultaneous (asynchronous torsion) early contralateral orchiopexy done at the time of exploration would prevent the occurence of asynchronous torsion. Non.operative maneuvres to detorse in NTT are not successful and not recommended. This review focuses on the diagnostic approach and management.
睾丸沿精索轴发生旋转会导致组织缺血和睾丸扭转（TT）。1 月龄新生儿的 TT 称为新生儿 TT（NTT）或围生期 TT，发病率为 6.1/100000 活产儿。由于部分 NTT 可能发生在产前且无症状，实际发病率可能更高。TT 可分为鞘外型、鞘内型和精索内型，而 NTT 通常为鞘外型。体格检查即可做出诊断，超声（US）的主要作用是排除其他情况。如果扭转发生在产前，睾丸可能无法挽救。但是，在某些情况下，可能会出现无症状的双侧 TT。如果扭转的时间不同步（异步扭转），在探查时同期对侧行睾丸固定术可预防异步扭转的发生。不推荐对 NTT 行非手术复位。本综述重点介绍诊断方法和治疗。
