Aufgrund der anatomischen Besonderheiten des Kaninchens unterscheidet sich die sonografische Untersuchung von der bei Hund und Katze. Die Wahl geeigneter Ultraschallger\u00e4te ist essenziell; empfohlen werden hochfrequente Linearschallk\u00f6pfe mit kleiner Auflagefl\u00e4che. F\u00fcr die Untersuchung wird das Kaninchen in R\u00fcckenlage auf einer weichen Unterlage positioniert, wobei eine Fixierung der Hintergliedma\u00dfen in der Regel nicht notwendig ist. Der Untersuchungsgang erfolgt standardisiert, meist beginnend an der Harnblase, die gut darstellbar ist und aufgrund des Kalziumstoffwechsels des Kaninchens h\u00e4ufig korpuskul\u00e4re Teilchen aufweist. Eine h\u00e4ufige Erkrankung ist die Urolithiasis. Dabei k\u00f6nnen sowohl Blasengrie\u00df als auch Konkremente im gesamten Harntrakt auftreten und Obstruktionen verursachen.<\/jats:p>\n                  <jats:p>Der weibliche Geschlechtstrakt des Kaninchens mit Zervix duplex und Uterus duplex wird systematisch sonografisch untersucht. Wichtige Pathologien sind insbesondere die endometriale Hyperplasie und das h\u00e4ufig auftretende uterine Adenokarzinom, gekennzeichnet durch Wandver\u00e4nderungen und Fl\u00fcssigkeitsansammlungen im Lumen des Organs. Die Sonografie spielt hier eine wichtige Rolle in der Fr\u00fcherkennung.<\/jats:p>\n                  <jats:p>Nebenniere und Milz lassen sich ebenfalls sonografisch darstellen, wobei letztere zungenf\u00f6rmig und von mittlerer Echogenit\u00e4t ist. Das Pankreas gilt als schwer darstellbar, ist aber in bestimmten Abschnitten erkennbar. Die Leber ist sonografisch gut beurteilbar; insbesondere der Lobus caudatus ist leicht zug\u00e4nglich. Bei einer Leberlappentorsion zeigen sich in der Sonografie Ver\u00e4nderungen in Echogenit\u00e4t und Durchblutung, oft begleitet von freier Fl\u00fcssigkeit und umgebender Gewebsreaktion.<\/jats:p>\n                  <jats:p>Der Gastrointestinaltrakt ist aufgrund von Gas und Futterresten nicht immer vollst\u00e4ndig einsehbar, doch bestimmte Abschnitte wie Magen, Duodenum, Sacculus rotundus und Appendix lassen sich meist gut darstellen. Sonografische Merkmale wie Wanddicke und Schichtung helfen bei der Beurteilung. Eine wichtige Erkrankung des Magen-Darm-Traktes ist die Appendizitis\/Sacculitis, die sich durch eine verdickte Wandung und ein gef\u00fclltes Lumen auszeichnet.<\/jats:p>","DOI":"10.1055\/a-2773-7520","type":"journal-article","created":{"date-parts":[[2026,4,24]],"date-time":"2026-04-24T23:07:11Z","timestamp":1777072031000},"page":"104-116","source":"Crossref","is-referenced-by-count":0,"title":["Abdominale Sonografie beim Kaninchen (Oryctolagus cuniculus) \u2013 physiologische und wichtige pathologische Befunde"],"prefix":"10.1055","volume":"54","author":[{"given":"Tina","family":"Brezina","sequence":"additional","affiliation":[{"name":"Zentrum f\u00fcr Tiergesundheit Baden-Baden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Heike","family":"Karpenstein-Klumpp","sequence":"additional","affiliation":[{"name":"Zentrum f\u00fcr Tiergesundheit Baden-Baden"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2026,4,24]]},"reference":[{"key":"ref1","volume-title":"Sonographische Untersuchung des Abdomens bei Kaninchen [Dissertation]","author":"C Nastarowith-Bien","year":"2008"},{"key":"ref2","volume-title":"Sonographische Befunderhebung am m\u00e4nnlichen und weiblichen Harntrakt und am weiblichen Geschlechtsapparat von Zwergkaninchen und Meerschweinchen [Dissertation]","author":"A Niebergall","year":"2003"},{"key":"ref3","doi-asserted-by":"crossref","first-page":"94","DOI":"10.22233\/9781910443163.8","volume-title":"Harcourt-Brown F, Chitty J, eds.
