The painful scrotum: torsion vs epididymo-orchitis.

In summary, an acute disorder of the scrotum in a child without previous urologic history must be viewed as torsion until proved otherwise by surgical exploration. No deleterious effects have been reported from such an approach, which requires a minimal period of hospitalization and little discomfort to the child. The shorter the interval between the onset of symptoms and surgical exploration, the greater the likelihood that the testicle will be viable later. The diagnosis of epididymo-orchitis in a healthy child without a history of urologic abnormality or evidence of lower urinary tract infection has no place in the differential diagnosis of the child with the painful scrotum.
