A total of 77 consecutive children ranging in age from 1 day to 17 yea
rs was evaluated for an acute scrotum by a single examiner (E. J. K.).
In 10 children a definite diagnosis of acute spermatic cord torsion w
as made based upon the history and physical examination. No imaging st
udies were performed and torsion was confirmed at surgery in 9 childre
n. The diagnosis of testis torsion was not as clear-cut in the remaini
ng 67 children and, therefore, a color Doppler ultrasound was performe
d before any surgical intervention. The study demonstrated normal or i
ncreased blood flow in 55 of these children and none proved to have te
sticular torsion, although other scrotal pathology requiring surgery w
as noted in 5 children. Twelve children did not demonstrate evidence o
f testicular blood flow on the color Doppler ultrasound and all had su
rgical confirmation of testis torsion. We conclude that in our experie
nce the majority (71%) of children with an acute scrotum did not requi
re immediate surgical exploration. Color Doppler ultrasound can reliab
ly identify those children with an acute scrotum who require explorati
on and spare the majority needless surgery. Routine scrotal exploratio
n is no longer necessary for all children with an acute scrotum.
