“…A evisceração da bexiga através da vagina pode ser observada em todas as espécies, ocorrendo mais comumente em animais domésticos de grande porte no período pré ou pós-parto, sendo rara em animais de pequeno porte (TONIOLLO, 2004;PRASSINOS et al, 2010).…”

“…Em alguns casos, devido às alterações resultantes dos transtornos circulatórios, é necessária a realização de celiotomia mediana para tracionamento e reposicionamento da bexiga (PRASSINOS et al, 2010). O prognóstico apresenta-se favorável desde que o paciente seja atendido rapidamente e que não haja lesões extensas no órgão, tornando inviável sua preservação (VICENTE, 1985;TONIOLLO, 2003;TONIOLLO et al, 2004).…”

“…The author has been associated with a very relaxed birth canal (9). The other case report about dystocia and bladder retroflexion was reported in a marsh deer (Blastocerus dichotomus) (26). In their case report, the retroflexion of the bladder occurred together with a rectal prolapse.…”

Summary: This article describes a 2.5 years old cross breed bitch, weighing 35 kg, with dystocia and a large mass protruding through the vulva. A surgical resection of a type III vaginal prolapse had been performed 1.5 years previously. On admission, transabdominal ultrasonography revealed several live foetuses in the uterine horns, but the urinary bladder was not visible in the abdomen. An anechogenic, fluid-filled bladder was observed during ultrasonography of the protruded mass. Foetuses were removed by caesarean section. During the surgery, it was realized that the uterine body and a live foetus were confined within the vagina as well as the bladder. The foetus was removed by repositioning the corpus uteri and bladder gently, and ovariohysterectomy was performed. Although the situation is exceptional, urinary bladder retroflexion could occur due to the failure of supportive connective tissue of pelvic floor and extreme straining during parturition. Therefore, retroflexion should be managed as an emergency to reduce the pressure in the bladder and to rescue the foetus if it is in the protruded tissue into the vagina.Keywords: Bitch, bladder retroflexion, dystocia. Bir köpekte vajinanın konnektif dokusunun yetersizliği ve güç doğum ile birlikte seyreden idrar kesesi retrofleksiyonu olgusuÖzet: Bu olguda, 2,5 yaşında ve 35 kg ağırlığında melez ırk bir köpekte rastlanan güç doğum şikayeti ile birlikte vulvada büyük bir kitle olgusu sunuldu. Alınan anamnezde, 1,5 yıl önce köpeğe tip III prolapsus vagina nedeniyle submukozal rezeksiyon operasyonu uygulandığı öğrenildi. Kliniğimizde yapılan transabdominal ultrasonografik muayenede uterusta birkaç adet canlı fetüs saptanırken, idrar kesesi abdomen içinde gözlenemedi. Vulvadan dışarı çıkan kitleye yapılan ultrasonografi muayenesinde anekojenik yapıda, içi sıvı dolu idrar kesesi görüldü. Fetüsler sezaryen operasyonu ile alındı. Operasyon sırasında, korpus uteri ve bir adet canlı fetüs ile birlikte idrar kesesinin vagina duvarı içinde sınırlı olduğu saptandı. Korpus uteri ve idrar kesesi dikkatle abdominal boşluk içine alınarak fetüs çıkarıldı, ardından ovaryohisterektomi gerçekleştirildi. Bu olguya oldukça nadir rastlansa da, idrar kesesinin retrofleksiyonu pelvis tabanını destekleyen konnektif dokudaki yetersizliğe ve doğum sırasında aşırı ıkınmalara bağlı olarak şekillenebilmektedir. Bu nedenle, idrar kesesindeki basıncın azaltılması ve kitle içinde olabilecek fetüsün kurtarılabilmesi amacıyla olguya hızla müdahale edilmesi gerekmektedir. Anahtar sözcükler: Güç doğum, idrar kesesi retrofleksiyonu, köpek.

“…In dogs, acquired changes in the urinary bladder's anatomical position are uncommon (Arbeiter & Bucher ). It has been most commonly described associated with two major conditions: perineal hernia in geriatric dogs due to weakness and separation of pelvic diaphragm components (White & Herrtage , Niles & Williams , Brissot et al ), and increased intra‐abdominal pressure during parturition in females, which culminates in vesical prolapse due to excessive straining or following trauma to the vagina (Mcnamara , Toniollo et al , Hayes , Prassinos et al ). In both conditions, displacement of other abdominal organs, including the small intestines and uterine body, has been reported (Mcnamara , Prassinos et al ).…”

This report describes the exteriorisation of the urinary bladder in two dogs as a result of a laceration of the rectum from a traumatic pelvic fracture. Clinical examination and contrast radiography of the bladder were used as diagnostic tools. Both patients were treated with exploratory laparotomy, where traction of the bladder was utilised to pull the bladder through the traumatic rectal laceration allowing the organ to return to its normal anatomical position. This procedure was followed by surgical reconstruction of the rectum, resulting in effective resolution of each case.
