Testicular torsion in children: scintigraphic assessment.

Seventy-five patients with suspected testicular torsion who had scintiscans and adequate clinical follow-up were analyzed retrospectively. The scintiscans diagnosed 12/13 cases of surgically proven missed torsion and 3/3 cases of surgically proven acute complete torsion. The scintiscans successfully distinguished all 35 cases of epididymo-orchitis, 14 cases of torsion of the appendix testes and 8 other miscellaneous conditions from testicular torsion. The incidence of testicular torsion in our patients undergoing scrotal scintigraphy was approximately 24%.
