Factors Determining Testicular Torsion and Consequent Orchiectomy in Pediatric Patients Presenting With Scrotal Pain

OBJECTIVE: Factors associated with testicular torsion (TT) and consequent orchiectomy in patients presenting to pediatric emergency departments (PEDs) with scrotal pain (SP) are not well described. We report the factors predicting TT and consequent orchiectomy in children with SP. METHODS: The data on patients (aged ≤18 years) who presented with SP to PEDs at 4 branches of the Chang Gung Hospital through 10 years were analyzed. RESULTS: In all, 256 pediatric patients presented with SP. Their mean age was 11.60 ± 4.61 years and 72.7% (n = 186) were aged 10 to 18 years. The pain was left-sided in 54.7% (n = 140) and the interval between SP onset and PED arrival was 22.45 ± 31.27 hours. Overall, 84 (32.8%) patients needed surgery and 72 (28.1%) had TT. Of the patients with TT, 28 (38.9%) patients needed an orchiectomy. After analysis, TT and consequent orchiectomy were associated with a longer interval between SP onset and PED arrival, absent of testicular ultrasonic blood flow, interval between SP onset and surgery of more than 24 hours, and a high degree of TT. None of them experienced recurrent SP symptoms or TT again. CONCLUSIONS: The rate of TT in patients presenting to PEDs with an SP was 28.1%, and 38.9% of the patients with TT needed an orchiectomy. Early diagnosis and intervention helped to prevent subsequent orchiectomy in pediatric patients with TT.
