The Role of Doppler Ultrasound in the Diagnosis of Postnatal Testicular Torsion in Children

The diagnostic significance of the color Doppler study of testicular blood flow in testicular torsion has been studied for about 40 years, however, the prognostic value of the results obtained is ambiguous, as are the actual imaging capabilities of the technique. Our own experience of 110 observations of testicular torsion in children older than the neonatal period allows us to draw statistically reliable conclusions. Made on equipment premium-class research made it possible to evaluate how visualization intratesticular vascular pattern, and whirpool-sign and submit the primitive model of the actual inversion, explaining the impossibility of rendering whirpool-sign with the greatest tight inversion. The dynamics of testicular blood flow was studied immediately after successful and unsuccessful manual detorsion and in the long term after operative detorsion and orchopexy. The publication contains a brief analysis of the literature and is extensively illustrated.

Testicular Blood Flow

As testicular torsion is a medical emergency, it requires quick diagnosis and treatment. Color Doppler ultrasound (CDUS) is useful for the diagnosis of testicular torsion. An accurate diagnosis can be difficult when CDUS indicates the preservation of blood flow in the testis. We examined the accuracy of testicular torsion diagnosis in patients with acute scrotum made by doctors on duty using CDUS. The subjects included 26 patients who visited our department between January 2016 and June 2018 presenting with acute scrotal pain. Patients were placed into one of three groups based on testicular blood flow evaluated by CDUS. The first group had no testicular blood flow, the second had diminished blood flow, and the last group had normal or increased blood flow. Patients were also diagnosed through scrotal exploration. Finally, patients were further divided into two groups identified by CDUS frequency utilized during diagnosis (12 MHz groups and ≤8 MHz groups), and the diagnostic accuracy of the two groups was compared. Characterizing torsion by either the absence of or diminished, testicular blood flow in the CDUS evaluation, the sensitivity and specificity of the CDUS performed by doctors on duty accounted for 69.2% and 53.8%, respectively. No improvement in diagnostic accuracy was evident despite the usage of a 12-MHz ultrasonic transducer. In this study, the sensitivity of CDUS performed by doctors on duty was about 70%, suggesting that scrotal exploration should be performed promptly even if testicular blood flow is observed and testicular torsion is suspected from medical history and body findings.

Doppler Study

Objective The study aimed to utilize the neurosonographic findings in neonates in early diagnosis, prediction of their long-term outcome, parental counseling, and early intervention. Methods The study was carried out in neonatal intensive care unit (NICU) of Shri BM Patil Medical College and Hospital. All preterms and term babies with neurological clinical findings were included in the study. Neurosonogram was done within first 7 days in preterms and when indicated in terms. Philips HD11XE ultrasound and color Doppler unit were used with a small footprint probe. Color Doppler images for vessels were performed for screening of vascular changes. Results A total of 215 babies were included, of which 80 (32%) were term and the rest were preterm. Mean weight of term babies was 2.8 kg and that of preterm was 1.2 kg.Among term babies, 78% showed ultrasound abnormality, and among preterm, 42%showed abnormalities. Among term babies, 60% and, among preterms, 30% had birth asphyxia. Periventricular leukomalacia was the most common and earliest finding followed by thalamic hyperechogenicity and intracranial hemorrhage. Intraventricular hemorrhage was more common in preterm babies. Other common finding in NICU was meningitis which was more common in pretrms. Among congenital anomalies, corpus callosal agenesis was more common. Conclusions Point of care ultrasonography along with Doppler study is very useful and safe to use in NICUs. It helps in diagnosis, patient management as well as prediction of many short- and long-term outcomes.
