Abstract
OBJECTIVE: This study aimed to summarize clinical manifestations, and physical examination, laboratory examination, and ultrasound results of children with testicular torsion <360°. METHODS: We performed a retrospective study of children who were diagnosed with testicular torsion <360° between October 2007 and October 2017. RESULTS: There were 11 (19.2%) patients with testicular torsion of 90°, 33 (58.0%) with 180°, and 13 (22.8%) with 270°. The median age of onset was 5.7 years (range, 1-14 years) and the median duration of symptoms was 4.2 days (range, 0.5-5 days). Ultrasound showed low blood flow in 46 (80.8%) patients. The testis was retained in 41 (72.0%) patients and resected in 16 (28.0%). The testes appeared necrotic at 2 to 3 days after onset for patients with 270° torsion, appeared necrotic at 3 to 4 days after onset for those with 180° torsion, and were not necrotic at 4 to 5 days after onset for those with 90° torsion. The duration of symptoms in children decreased as the torsion angle increased. CONCLUSION: Children with testicular torsion <360° are relatively young, while the duration of symptoms is relatively long. A high postoperative testicular survival rate is one of the clinical features in this study.
