[Viral infections in urology]. / Virusinfektionen in der Urologie.

INTRODUCTION: The COVID (coronavirus disease 2019) pandemic has shown impressively that infectious diseases can have an enormous impact on the healthcare system and beyond. In the specialty of urology, patients present in daily practice with viral infections that are associated with numerous diseases. METHODOLOGY: The aim of this review is to describe viral infections relevant for urology, and in particular to emphasize vaccination prevention. A selective literature search was carried out on the subjects of "COVID and urology", "urogenital viral infections", "viral urological infections in transplant medicine", and "vaccination prevention of viral diseases". RESULTS: Coronaviruses have already caused two local epidemics: SARS (severe acute respiratory syndrome) epidemic and MERS (Middle East respiratory syndrome) epidemic. The fact that the SARS-CoV­2 (SARS coronavirus 2) disease is contagious even without symptoms has essentially led to the rapid spread and global pandemic. A large number of viruses, which can also induce viremia, have been detected in the ejaculate and are thus associated with a possible urogenital infection. These include the mumps virus, Coxsackie viruses or enteroviruses, among others. It has also been shown that a Zika virus infection can also be sexually transmitted via the sperm as a carrier. Viruses therefore also play an important role in reproduction. When performing kidney transplants, urologists are often confronted with viral infections. The most effective weapon against viruses is prevention by vaccination. CONCLUSION: In terms of ethiopathogenesis, the genitourinary tract is most often affected by viruses, in the context of viremia or through reactivation due to immunosuppression. Immunomodulation and vaccination prophylaxis play a leading role in therapy.
