Abstract
To determine the usefulness of computerized tomography (CT) scanning in the preoperative localization of the impalpable undescended testis 5 patients with 8 impalpable testes were studied. In 2 patients the scan correctly outlined 3 impalpable testes inside the internal inguinal ring, in 2 patients the scan correctly localized 4 impalpable testes at or just inside the external inguinal ring and in 1 patient the scan failed to demonstrate a testis, a finding corroborated at an operation. Apparently, CT scanning appears to be an effective, simple and less hazardous method to localize impalpable undescended testes than other currently available techniques.
