This study aimed to conduct a retrospective study on vaginal and uterine prolapse in sheep seen at the Clinic and Surgery on Cattle and Small Ruminants (CBPR) at University of São Paulo, from 2000 to 2010. During this period, 56 sheep were treated with problems of the reproductive system. Of these, 25 ewes had vaginal or uterine prolapse (44.6%). The total vaginal prolapse was the most frequently (72%). The majority of sheep that was affected were 4 years old (64%); most were mixed breed (44%) and 40% were Ile de France. Main clinical signs were increased cardiac and respiratory rates, congested ocular mucosa, sternal or lateral recumbence, apathy and anorexia, suggesting toxemia. The treatment of all cases was the cleaning and disinfection of the prolapsed organ and its reintroduction. The Bühner suture was made in 84% of the cases. The uterus fixation was made in one case (4%). Recovered was observed in 80% of the cases and 20% of the patients died. Vaginal prolapse corresponded to 60% of the deaths and uterine prolapse to 40%. The etiology of the prolapses had not been defined, but most cases (56%) occurred during the postpartum period, probably associated with hypocalcaemia, high serum concentrations of estrogen or uterine hypertonia. Furthermore, a genetic predisposition on affected sheep cannot be discharged. |
