Twenty-eight pediatric cases of acute epididymitis (AE) managed over t
he last ten years are reported. After exclusion of acute post-traumati
c scrotal swelling, idiopathic scrotal edema, and processus vaginalis
abnormalities, acute unilateral scrotal disorders seen during the stud
y period were distributed as follows: torsion of an appendage, 63%; pe
rinatal torsion of the spermatic cord, 5%; torsion of the testis, 25%;
and AE, 7%. The role and value of diagnostic investigations in AE are
discussed. Urine cultures should be performed routinely. Surgery was
required in one-third of confirmed cases. Sixteen patients had a uroge
nital tract abnormality that was either known prior to the episode of
AE or discovered during the work-up routinely performed in this condit
ion (renal ultrasonography or intravenous urography and urethrocystogr
aphy). Residual lesions should be evaluated over the long term.
