Clinical implications of gonadal venography in the management of the non-palpable undescended testis

Abstract

Selective gonadal venography was used on 28 patients with a total of 34 non-palpable undescended testes. The data obtained in this study suggest that 1) an internal spermatic vein with a pampiniform-like plexus indicates the presence of a testis, 2) a blind-ending vein on venography suggests the absence of a testis, 3) an internal spermatic vein or vas deferens may be present without a testis, 4) a testis probably cannot be present without a gonadal vein, 5) a testis may be present without a vas, 6) a blind-ending vas deferens does not necessarily indicate the absence of a testis and 7) a blind-ending vas deferens in a patient in whom a blind-ending gonadal vein is localized to the same region probably indicates the absence of a testis. Gonadal venography may localize a non-palpable undescended testis or suggest testicular agenesis. In addition, gonadal venography has aided in the selection of the operative approach and, in the future, may provide criteria under specific circumstances for determining whether an operation is necessary and, if so, the extent of surgical exploration.

COVID-19

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.
