CT in localization of impalpable cryptorchid testes

AJR. American Journal of Roentgenology
M K WolversonE Houttuin


Computed tomography was used for preoperative localization in 12 patients with undescended testes. Because three patients had bilateral involvement, 15 absent or undescended testes were studied. Surgical confirmation of the CT findings was obtained in 12 instances. Confirmation was not obtained in one patient who refused operation and it was considered incomplete in another due to limited surgical exploration. There was one incorrect localization. The procedure is quick, simple, noninvasive, and can be performed at all ages. The testicular radiation exposure was considered acceptable on the basis of phantom measurement. The lowest possible exposure factors were used on all patients. CT findings assisted planning of operative procedures and in some cases enabled more limited and shorter operations.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.
