The value of computed tomography in the localization of undescended testes.

Eight patients with unilateral and four with bilateral (4) unpalpable testes were evaluated with CT for localization. All patients were later submitted to laparascopy and/or surgery and 13 cryptorchid testes and 3 atrophic or agenesic testes were found. CT detected correctly 11 of the cryptorchid testes - (85%) with one false positive and one false negative finding. In the three atrophic or agenesic testes, CT did not identify any image suspicious of being a testis, so there three were no false positive studies here. It is concluded that CT is an accurate noninvasive method for the preoperative detection of cryptorchid testes.
