H\u00e4ufige Ursachen f\u00fcr eine Urachusfistel sind kongenitale Defekte, das Abrei\u00dfen des Nabelstrangs oberhalb der Pr\u00e4dilektionsstelle, Traumata, erh\u00f6hter intravesikaler oder abdominaler Druck und Nabelinfektionen. Die Urachusfistel wird des \u00d6fteren bei pr\u00e4maturen oder lebens- und immunschwachen Fohlen beobachtet. Hengstfohlen sind h\u00e4ufiger betroffen als Stutfohlen. Erkrankte Fohlen zeigen entweder direkt nach der Geburt (Urachus persistens) oder meist 7\u201314 Tage post natum (Urachus patens) typische klinische Symptome wie Harntr\u00e4ufeln w\u00e4hrend der nat\u00fcrlichen Miktion oder Harnabsatz im Strahl \u00fcber den Hautnabel sowie eine feuchte Nabelumgebung. Die Diagnose l\u00e4sst sich i. d. R. eindeutig stellen. Typische labordiagnostische Befunde sind f\u00fcr die Urachusfistel nicht beschrieben. Konservative Therapieversuche mittels Ver\u00f6dung, Kauterisation oder Kryochirurgie k\u00f6nnen erfolgen, solange keine entz\u00fcndlichen Ver\u00e4nderungen des Urachus und der \u00fcbrigen Nabelstrukturen vorliegen und das Urachuslumen bis zu 6 mm betr\u00e4gt. Eine Nabelresektion ist dann indiziert, wenn ein sehr weites Urachuslumen, eine begleitende Nabelinfektion oder eine Sepsis vorliegt oder wenn sich nach 5\u20137 Tagen konservativer Behandlungsdauer kein Therapieerfolg einstellt. In den meisten F\u00e4llen besteht eine gute Prognose, doch k\u00f6nnen Komplikationen wie Nabelentz\u00fcndungen, streuende Infektionen und sekund\u00e4re Gelenkerkrankungen die Prognose erheblich verschlechtern.<\/jats:p>","DOI":"10.1055\/a-1523-2711","type":"journal-article","created":{"date-parts":[[2021,8,23]],"date-time":"2021-08-23T22:33:51Z","timestamp":1629758031000},"page":"275-280","source":"Crossref","is-referenced-by-count":0,"title":["Urachusfistel beim neugeborenen Fohlen \u2013 eine Literatur\u00fcbersicht"],"prefix":"10.1055","volume":"49","author":[{"given":"Andr\u00e9","family":"Bernick","sequence":"additional","affiliation":[{"name":"Klinik f\u00fcr Geburtshilfe, Gyn\u00e4kologie und Andrologie der Gro\u00df- und Kleintiere, Klinikum Veterin\u00e4rmedizin, Justus-Liebig-Universit\u00e4t Gie\u00dfen"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jennifer","family":"Nieth","sequence":"additional","affiliation":[{"name":"Klinik f\u00fcr Geburtshilfe, Gyn\u00e4kologie und Andrologie der Gro\u00df- und Kleintiere, Klinikum Veterin\u00e4rmedizin, Justus-Liebig-Universit\u00e4t Gie\u00dfen"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Axel","family":"Wehrend","sequence":"additional","affiliation":[{"name":"Klinik f\u00fcr Geburtshilfe, Gyn\u00e4kologie und Andrologie der Gro\u00df- und Kleintiere, Klinikum Veterin\u00e4rmedizin, Justus-Liebig-Universit\u00e4t Gie\u00dfen"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2021,8,23]]},"reference":[{"key":"ref1","doi-asserted-by":"crossref","first-page":"357","DOI":"10.15653\/TPG-161102","article-title":"Inzidenz und Letalit\u00e4t h\u00e4ufiger neonataler Erkrankungen beim Fohlen w\u00e4hrend der ersten 10 Tage post natum in einer Veterin\u00e4rklinik","volume":"45","author":"M Gra\u00dfl","year":"2017","journal-title":"Tierarztl Prax Ausg Grosstiere Nutztiere"},{"key":"ref2","volume-title":"Urachus","author":"Roche Lexikon Medizin","year":"2003","edition":"5.
