AbstractWe aimed at verifying the usefulness of spectral Doppler ultrasonography in determining development of the testis after torsion in boys.The study involved 28 patients and 30 control cases divided into 3 developmental groups: pre-pubertal, early pubertal, and pubertal. It presented surgical management in testicular torsion (TT), volume, and echogenicity of testes, as well as peak-systolic velocity (PSV), end-diastolic velocity (EDV), and vascular resistance index (RI) in the capsular and intra-testicular arteries, regarding developmental groups, detorsed testes, uninvolved ones, and testes in the control group.Orchiectomy was performed in 13 boys with complete TT, in 11 lasting for over 24 hours, and in 2 lasting for 9 and 10 hours, respectively. Orchiectomy mainly involved patients aged up to 6 years, who at the time of the follow-up ultrasound belonged to the pre-pubertal group.There is no clear correlation between the type of testicular torsion, its duration, and the echogenicity of the testis. Testicular torsion has a negative effect on the volume of detorsed testis with compensatory hypertrophy of the uninvolved testis. The study represents a new approach to the issue of long-term gonadal blood supply abnormalities after treatment of testicular torsion in childhood.Copyright © 2021 the Author(s).
