RESUMO
A 2-year-old Pomeranian-Spitz dog (5.8 kg) was admitted with symptoms of uterine prolapse and lethargy 1 day after whelping three puppies. The prolapsed uterus was corrected, but the next day, prolapse reoccurred. To fix the cervix to the abdominal wall, the dog underwent a surgery operation where intussusception in the left horn of the uterus was found. Ovariohysterectomy was performed as the treatment of choice. The diagnosis of intussusception is challenging, and exploratory laparotomy is the reliable diagnostic approach. Although uterine intussusception is rare, it should be one of the important considerations in dogs within the post-partum period.

A ten-year-old mixed breed bitch was presented for a tissue prolapse protruding from her vulva. Following detailed examination and stabilization, the ovaries and uterine horns were removed by laparotomy, whereas the prolapsed tissue identified as uterus including cervix was removed vaginally. Histology confirmed uterine prolapse, a rare condition in bitches usually found shortly after birth especially due to dystocia. In contrast, the present case was found in a nulliparous non-pregnant bitch. Diagnostic and therapeutic approaches, including microbiological and histological findings, are described and discussed critically.

BACKGROUND: Bovine uterine prolapse is a sporadic but life-threatening postpartum condition. The aims of this study were; (i) to determine which clinical findings determined the likelihood of treatment vs. culling, (ii) to identify the treatment methods currently employed by Norwegian veterinary surgeons and evaluate their effect on survival, (iii) to determine if clinical findings at the time of treatment could be used to determine prognosis. Practicing veterinary surgeons in Norway were contacted and asked to fill out a questionnaire on cases of bovine uterine prolapse they attended between February and October 2012. The questionnaires gathered data on signalment, clinical presentation, treatment, and outcome. These data were supplemented with culling data from the Norwegian Dairy and Beef Herd Recording Systems. The chi-squared test and logistic regression modelling was performed to identify likelihood of treatment and cox proportional hazard modelling was performed to identify the hazard of death after treatment. RESULTS: Data from 126 cases of bovine uterine prolapse were collected (78 beef and 48 dairy cows). Twenty-six cows (21%) were emergency slaughtered, or underwent euthanasia, without treatment. Of the remaining 100 cases amputation of the uterus was performed once and repositioning was performed in 99 cases. Survival data were missing from 2 of the cases that had undergone treatment leaving a study sample of 97 cases (64 beef and 33 dairy cows). Multivariable logistic regression analysis of the explanatory variables showed that beef cows were more likely to be treated than dairy cows (OR = 0.32, 95% CI 0.13 to 0.81, P = 0.017) and that cows with a significantly oedematous or traumatised uterus were less likely to be treated (OR = 0.26, 95% CI 0.10 to 0.67, P = 0.006). Treatment methods amongst Norwegian practitioners were broadly similar. In a multivariable model cows general clinical state at time of treatment was positively correlated with survival (HR = 0.29, 95% CI 0.29 to 0.73, P = 0.008) and a history of a vaginal prolapse prepartum increased the hazard of death (HR = 2.31, 95% CI 1.08 to 4.95, P = 0.031) in the first 30 days after treatment of a uterine prolapse. In the first 180 days after treatment only veterinary assessment of a cows' general clinical state was correlated with hazard of death (HR = 0.432, 95% CI 0.20 to 0.91, P = 0.046). CONCLUSIONS: This study shows that the production system and extent of uterine damage affect the likelihood of treatment, and that practitioners use similar treatment methods. A cows' general clinical state at time of treatment was positively correlated with survival, and a history of a vaginal prolapse prepartum increased the hazard of death in the first 30 days after treatment of a uterine prolapse.

True vaginal prolapse is rare in bitches and is most likely to occur near whelping. A 2-year-old intact female Brazilian mastiff, 39.5 kg, had a true vaginal prolapse associated with urinary bladder retroflection; the female was in estrus, and concomitantly had diarrhea for 3 d, plus vaginal hyperplasia, and ultimately a vaginal prolapse. Ultrasound examination and retrograde urethrocystography were extremely important for detection and identification of the position (retroflection) of the urinary bladder within the prolapsed vagina. These tools, therefore, are recommended for a conclusive diagnosis and surgical planning, to avoid trans- and postoperative complications, e.g., urethral damage or bladder rupture. Prompt diagnosis and surgical correction enabled a favorable prognosis and rapid postoperative recovery, avoiding complications or ultimately death of the dog.
Prolapsus vaginal vrai associé à une rétroflexion de la vessie chez une chienne. Le prolapsus vaginal vrai est rare chez les chiennes et est plus susceptible de se produire près de la mise-bas. Une femelle dogue brésilien intacte de 2 ans, pesant 39,5 kg, a eu un prolapsus vaginal vrai associé à une rétroflexion de la vessie urinaire; la femelle était en oestrus et avait simultanément de la diarrhée pendant 3 jours, plus une hyperplasie vaginale et finalement un prolapsus vaginal. L'examen échographique et l'urétrocystographie rétrograde étaient extrêmement importants pour la détection et l'identification de la position (rétroflexion) de la vessie dans le vagin faisant prolapsus. Ces outils sont donc recommandés pour un diagnostic concluant et une planification chirurgicale, afin d'éviter les complications trans- et postopératoires, par exemple des lésions urétrales ou une rupture de la vessie. Un diagnostic rapide et une correction chirurgicale ont permis un pronostic favorable et une récupération postopératoire rapide, évitant les complications ou éventuellement le décès du chien.(Traduit par Dr Serge Messier).

OBJECTIVE: To describe uterine prolapse, predispositions, and outcomes in mares treated between 1988 and 2019. ANIMALS: 24 mares with uterine prolapse. PROCEDURES: Clinical records were retrospectively reviewed, and follow-up information was gathered. The Mann-Whitney U test and Fisher exact test were used to analyze results for history and outcome variables for potential association with mare survival to hospital discharge. The χ2 test was used to compare breed distribution. RESULTS: Age was known in 23 mares (median, 11.1 years). For 15 mares with exact known parity, the median parity was 3 births (range, 1 to 13 births). For 22 mares, the maiden status was known (7 [32%] maiden; 15 [68%] multiparous). Breed distribution differed significantly between mares with uterine prolapse and all mares treated at the Veterinary Medical Teaching Hospital. Arabians were overrepresented in the uterine prolapse group (7/24 [29%]), compared with all mares treated (4,174/44,474 [9%]). Uterine prolapse occurred within 2 hours after parturition for 10 of 11 mares with known foaling times, after dystocia for 7 mares, and after abortion for 4 mares. Seventeen of 23 (74%) mares survived to hospital discharge. Acute hemorrhage was the most frequent cause of death. There were no correlations between mare survival to hospital discharge and mare parity or age, foal sex, retained fetal membranes, sepsis, or maiden status. Colts were overrepresented in foals with a known sex (12/17). CLINICAL RELEVANCE: Results indicated a breed predisposition to uterine prolapse, with Arabian mares overrepresented among affected mares. No characteristics correlated with mare survival to hospital discharge.

Reproductive diseases have been well documented in domestic livestock such as sheep, goat, cattle and pigs. However, there is very little information on these diseases in the agouti (Dasyprocta leporina). The agouti is used for its meat in South America and the Caribbean. More recently, intensive farming of this animal is being practiced in the Neotropics. There is dearth of information on dystocia and vaginal prolapses in the agouti. This document reports on three cases of reproductive diseases in captive reared agoutis in Trinidad and Tobago. The first case was a female agouti weighing approximately 3 kg that was in the last stage of pregnancy, which was found dead in its cage. The vulva of the mother had the protruding hind-limbs of the fetus. Necroscopic evaluation of carcass revealed little fat tissue and the mother had two fetuses in the right horn of the uterus. Each fetus weighed approximately 200 g. The fetuses were well formed with fur, teeth and eyes. The placenta was attached to each fetus. The pathological findings suggested that dystocia resulted from secondary uterine inertia which was the cause of death of the adult female agouti. The second case was that of an adult female agouti weighing 2.5 kg. This female had given birth to an offspring three weeks prior and was observed to have had a vaginal prolapse. Surgery was performed and the prolapsed vagina was placed back into the pelvic cavity. Further to this intervention, the vagina prolapsed twice. Subsequent to the re-insertion of the vaginal tissue the agouti was euthanized. The third case was also that of a dystocia. However, the fetuses weighed 235 g and 165 g respectively and were in normalpresentation, posture and positioning. The fetus however was unable to pass via the vagina and was trapped in the pelvic cavity. This caused secondary uterine inertia which was the cause of death. The causes of reproductive diseases in these cases are unknown but the feeding [...].
As doenças reprodutivas têm sido bem documentadas em rebanhos domésticos, como ovinos, caprinos, bovinos e suínos. Porém, há muito pouca informação sobre essas doenças na cutia (Dasyprocta leporina). A cutia é usada como carne na América do Sul e no Caribe. Mais recentemente, a criação intensiva desse animal está sendo praticada na região neotropical. Há escassez de informações sobre distocia e prolapsos vaginais na cutia. Este documento relata três casos de doenças reprodutivas em cutias criadas em cativeiro em Trinidad e Tobago. O primeiro caso foi de uma cutia de aproximadamente 3 kg que estava na última fase de gestação, encontrada morta em sua gaiola. A vulva da mãe tinha as patas traseiras salientes do feto. A avaliação necroscópica da carcaça revelou pouco tecido adiposo e a mãe tinha dois fetos no corno direito do útero. Cada feto pesava aproximadamente 200 g. Os fetos eram bem formados com pelos, dentes e olhos. A placenta foi presa a cada feto. Os achados patológicos sugeriram que a distocia resultou de inércia uterina secundária, que foi a causa da morte da cutia adulta. O segundo caso foi ode uma cutia adulta pesando 2,5 kg. Essa fêmea deu à luz uma cria três semanas antes e foi observado que tinha prolapso vaginal. A cirurgia foi realizada e a vagina prolapsada foi colocada de volta na cavidade pélvica. Após essa intervenção, a vagina prolapsou duas vezes. Após a reinserção do tecido vaginal, a cutia foi eutanasiada. O terceiro caso também foi de distocia. No entanto, os fetos pesavam 235 g e 165 g e estavam em apresentação, postura e posicionamento normais. O feto, entretanto, não conseguiu passar pela vagina e ficou preso na cavidade pélvica. Isso causou inércia uterina secundária, que foi a causa da morte. As causas das doenças reprodutivas nesses casos são desconhecidas, mas o manejo da alimentação e o espaço concedido à cutia no final da gestação podem ser fatores contribuintes.

Ovine pre-partum vaginal prolapse (known as bearings in sheep) occurs within a few weeks prior to lambing and unless treated both ewes and unborn lambs will die. It is a worldwide problem with no clear aetiology. Rates of prolapse in New Zealand typically vary from 0.1 to 2% per annum, varying between seasons and farms. In order to determine preclinical changes leading to prolapse, blood samples were collected prior to prolapse occurring and analysed for changes in both protein and specific hormone and vitamin levels. 650 ewes were ear tagged and blood samples were taken one month prior to the beginning of lambing; 28 of these ewes subsequently prolapsed. Using an improved proteomic method plasma samples were subjected to 2D DIGE (two dimensional differential in gel electrophoresis) to determine if there were differences between the pre-prolapse and non-prolapsing ewes. Acidic isoforms of haptoglobin, a major acute phase protein in ruminants, increased approximately 3-fold in ewes prior to prolapse occurring. Total haptoglobin quantitation was confirmed with an independent assay. Although another plasma protein, α-1B-glycoprotein, was down regulated close to prolapse, the biological significance of this is unknown. While vitamin D levels were not associated with subsequent prolapse there was, however, a negative correlation between cortisol and days to prolapse from sampling (r2 = 0.36); i.e. ewes sampled closest to prolapse had higher plasma cortisol concentrations than controls. This raises the possibility that the ewes which prolapsed may have been suffering from chronic stress. Further research is needed.

Selected conditions affecting broodmares are discussed, including arterial rupture, dystocia, foal support with ex utero intrapartum treatment, uterine prolapse, postpartum colic, the metritis/sepsis/systemic inflammatory response syndrome complex, and retained fetal membranes. Postpartum colic beyond third-stage labor contractions should prompt comprehensive evaluation for direct injuries to the reproductive tract or indirect injury of the intestinal tract. Mares with perforation or rupture of the uterus are typically recognized 1 to 3 days after foaling, with depression, fever, and leukopenia; laminitis and progression to founder can be fulminant. The same concerns are relevant in mares with retention of fetal membranes.

This report describes a surgical technique for resolution of uterine prolapse in rabbits. Three pet rabbits presented within 24 hours of parturition with a red mass protruding from the vagina, which was diagnosed as uterine prolapse. In the first case, an attempt to reduce the prolapse by manual compression was ineffective. A laparotomy was used to apply internal uterine traction while simultaneously using gentle external pressure with cotton-tip applicators and resulted in successful resolution. After repositioning, an ovariohysterovaginectomy was performed in all three rabbits. All rabbits recovered uneventfully. Laparotomic repositioning of the uterus and ovariohysterovaginectomy, not previously described in rabbits, was easy to perform and permitted resolution of uterine prolapse.

The aim of this study was to evaluate the prevalence of uterine prolapse in cows and assess its effects on survival and subsequent fertility. Of 33,450 calving cows considered retrospectively, 216 (0.6%) developed uterine prolapse. A higher prevalence was found in beef cows (n = 57/5,700 cows, 1%) compared to dairy cows (n = 157/27,750 cows, 0.6%). Treatment consisted of cleaning and replacing the uterus with local administration of antibiotics, and applying a harness for uterine containment. The recovery rate was 81.9% (n = 177), similar in dairy (n = 129; 81.1%) and beef (n = 48; 84.2%) cows. Of the 216 cows with uterine prolapse, 18 (8.3%) died before or immediately after treatment; 21 cows (9.7%) were voluntarily culled for economic reasons (low milk yield, low fertility, insufficient weight gain). All recovered dairy cows were artificially inseminated with semen of proven fertility after a voluntary waiting period of 50 days; the beef cows were naturally mated. Among the 172 inseminated/mated cows, 84.7% (n = 150) became pregnant (83.7% dairy cows, 87.5% beef cows), while 15.2% (n = 27) did not conceive. Recurrence of uterine prolapse at subsequent calvings was recorded in one dairy cow. Based upon the data presented here, treated cows with uterine prolapse showed high chances of survival and conception, and a low risk of recurrence.

The surgical procedure for a grade IV oestrogen-related vaginal fold prolapse in a Great Dane is described. Furthermore, the possibilities of conservative therapy for this disease are presented and a more recent surgical technique as well as the dog's postoperative course are discussed. The principle of conservative treatment is to shorten the bitch's cycle by means of medically inducing ovulation and thus subsequently reducing the influence of estrogens on the prolapsed tissue. Advantages of both therapeutic approaches are discussed. The presented case's interesting aspect is that conservative therapy did not lead to a successful outcome for which the cause is not clear.

Aim: To determine if vitamin D3 treatment reduced the incidence of vaginal prolapse in pregnant sheep on a North Canterbury sheep breeding property.Methods: Pregnant ewes from a single farm were allocated to three treatment groups in May 2018. At this time, the first group (EarlyVitADE; n = 512) received an I/M 1â mL dose of 500,000â IU/mL vitamin D3, 60,000â IU/mL vitamin A, and 25â mg/mL vitamin E. This was repeated in July 2018, when the second group (LateVitADE; n = 695) also received the same treatment. The third group (n = 737) were untreated controls. All cases of vaginal prolapse on the property were recorded from pregnancy diagnosis in June 2018 until ewes were set-stocked in August 2018. The planned start of lambing was 10 August 2018.Results: During the period of observation, vaginal prolapses were recorded in 3/699 (0.4%) 2-year-old ewes, and the odds of vaginal prolapse were not associated with treatment group in these ewes (p > 0.3). Amongst ewes aged ≥3 years, during the same period, there were 6/333 (1.8%), 6/443 (1.4%) and 25/469 (5.3%) cases in the EarlyVitADE, LateVitADE and control groups, respectively. Compared to control ewes, the odds of vaginal prolapse were reduced in both the EarlyVitADE (OR = 0.37; 95% CI = 0.15-0.92) and LateVitADE (OR = 0.25; 95% CI = 0.10-0.62) treatment groups.Conclusions and clinical relevance: In this preliminary study, administration of injectable vitamins A, D3, and E to pregnant ewes reduced the incidence of vaginal prolapse during the period from pregnancy diagnosis to set-stocking on one North Canterbury hill-country farm. Due to the restricted data collection period, this investigation should be replicated to better quantify the repeatability of the observed treatment effect over the complete lambing period.

Uterine intussusception is a rare condition in bitches. This study aimed to report an unusual case of prolapsed uterine intussusception in a female dog. A 2-year-old American Bully bitch was received with labor history of large fetus requiring manual traction. The animal presented mucosal prolapse through the vulva, unproductive contractions and abdominal discomfort. After partial correction of mucosal prolapse, the dog was referred to ovary-hysterectomy surgery to correct prolapsed mucosa. During the surgical procedure, surgeons observed that the uterine horns were invaginated into the uterine body, rotated, and the tissue was slightly devitalized and congested. As previously described, this condition occurred during the immediate postpartum period. Thus, we suggest that this period can be a facilitator for the establishment of uterine intussusception.(AU)
A intussuscepção uterina é uma condição rara em cadelas. Portanto, este estudo tem por objetivo relatar um caso incomum de intussuscepção uterina prolapsada em fêmea canina. Uma cadela American Bully de dois anos de idade com histórico de parto de feto absoluto grande no qual necessitou de auxílio por tração manual foi apresentada. O animal exibiu um prolapso de mucosa através da vulva, contrações improdutivas e dores abdominais. Após a retração parcial do prolapso de mucosa, a cadela foi encaminhada para a ovário-histerectomia que teve por objetivo, também, corrigir a mucosa prolapsada. Durante o procedimento cirúrgico, foram verificados os cornos uterinos invaginados no corpo uterino, rotacionados, com o tecido levemente desvitalizado e congesto. Assim, como poucos casos encontrados na literatura, esta condição ocorreu durante o puerpério imediato. Dessa forma, sugere-se que este período, embora não seja um fator determinante para o estabelecimento da intussuscepção uterina, pode ser um facilitador no estabelecimento dessa condição.(AU)

Prolapses in sows are an emerging concern in pig production. The objectives of this study were to estimate the incidence rate of prolapses and to determine risk factors associated with prolapse occurrences. Data included 905,089 service records in 819,754 parity records of 155,238 sows from 144 swine herds in Spain. Producers were required to record a removal reason, including type of prolapse. A 1:4 matched case-control study was carried out to investigate prolapse risk factors, and piecewise exponential models were applied to the data. The following factors were assessed: parity, number of services, service season, weeks after service, prior gestational length, total number of piglets born, and number of stillborn and mummified piglets. Almost 1% of sows (0.8%) were removed due to prolapses (95% confidence interval: 0.76, 0.85), and the annualized incidence rate for all prolapse cases was 3.8 cases per 1000 sow-years (95% confidence interval: 3.59, 4.01). Significant factors were the 16th week after service, being in parity 3 or higher, re-service, servicing in summer, autumn or winter, shorter gestational length, fewer piglets born and more stillborn piglets (P ≤ 0.04). For example, the prolapse incidence was 30.6 times higher at 16 weeks after service than during the first 14 weeks (P < 0.01). Also, 60.9% of 1198 prolapses occurred during the first 0 to 4 weeks after farrowing. The prolapse incidence was 1.5-1.8 times higher in parity 3 or higher sows than in parity 0 sows (P < 0.01), and 1.3 times higher in re-serviced sows than in first serviced sows (P = 0.02). It was also 1.3-1.5 times higher in sows serviced in summer, autumn or winter than in those serviced in spring (P ≤ 0.02), and 1.3-1.5 times higher in sows with a prior gestational length of 113 days or less than in sows with 114 days or more gestational length (P < 0.01). Lastly, the prolapse incidence rate was 1.2 times higher in sows with 11 or fewer piglets born than in sows with 12-16 piglets born (P = 0.04), and was also 1.4 times higher in sows with two or more stillborn piglets than in sows with no stillborn piglets (P < 0.01). However, there was no association between prolapse incidence and mummified piglets (P = 0.54). Consequently, producers should pay more attention to sows exposed to high risks, while trying to identify prolapse cases at an early stage.

CASE DESCRIPTION: A 7-year-old 42-kg (92.4-lb) sexually intact nulliparous female Italian Mastiff was examined because of a history of vaginal prolapse during diestrus. CLINICAL FINDINGS: A physical examination revealed vaginal fold prolapse. Abdominal ultrasonography revealed an enlarged uterus with hypoechogenic content, corpora lutea in the ovaries, and a cyst in the right ovary. Hematologic abnormalities included leukocytosis, neutrophilia, mild anemia, and low Hct. Progesterone and estradiol concentrations were 9.36 ng/mL and 30.42 pg/mL, respectively, in serum and 72.72 ng/mL and 792 pg/mL, respectively, in the ovarian cystic fluid. TREATMENT AND OUTCOME: Ovariohysterectomy was performed; the prolapsed tissue was repositioned by external manipulation and maintained in situ by temporary apposition of the vulvar lips with a retention suture. Anatomic and histologic examinations of the excised tissues revealed pyometra and papillary cystadenocarcinoma in the right ovary. The vaginal hyperplasia completely regressed at 35 days after surgery; 5 months after surgery, the dog's general condition was considered good. CLINICAL RELEVANCE: Findings in this case were indicative of a hormonally active ovarian papillary cystadenocarcinoma in a female dog in diestrus. Hormone production by the cystadenocarcinoma was the predisposing factor that induced pyometra, mucosal hyperplasia, and vaginal fold prolapse in the dog. On the basis of these concurrent disorders, ovariohysterectomy was an appropriate treatment.

O prolapso uterino em cadelas e gatas é uma emergência reprodutiva na qual ocorre eversão de um ou ambos os cornos uterinos através da vagina, durante ou após o parto. Tal patologia não é frequente em gatas, por isso o presente relato tem o objetivo de descrever um caso de prolapso uterino em uma gata atendida no Hospital Veterinário da Universidade Federal do Piauí. Na anamnese o proprietário se queixou de massa avermelhada na vulva após a expulsão de dois filhotes. Ao exame clínico, observou-se que a massa era o útero prolapsado. O animal foi encaminhado imediatamente ao centro cirúrgico para redução do útero prolapsado e realização de ovariosalpingohisterectomia (OSH). Após a OSH, o animal permaneceu internado durante 24 horas. Findo este período o animal teve alta e apresentou boa recuperação.
Uterine prolapse in dogs and cats is a reproductive emergency in which there is the protrusion of one or both uterine horns through the vagina during or after delivery. This condition is not common in cats, so this report aims to describe a case of uterine prolapse in a cat treated at the Veterinary Hospital of the Federal University of Piaui. Upon anamnesis, the owner complained of a reddish mass in the vulva after the expelling of two kittens. Clinical examination revealed that the mass was the prolapsed uterus. The animal was immediately sent to the operating room for reduction of the prolapsed uterus and an ovariosalpingohisterectomy (OSH) was performed. After OSH, the animal remained hospitalized for 24 hours. After this period, the animal was discharged and recovered well.

A uterine prolapse associated with a leiomyoma (fibroid) was observed in a live-stranded Atlantic spotted dolphin (Stenella frontalis). A 7 cm segment of the reproductive tract including the cervix, uterine neck and caudal uterine body had intussuscepted and prolapsed into the cranial vaginal vault. In the leading edge of the intussuscepted/prolapsed uterine wall was a 6 × 3 × 3.5 cm leiomyoma expanding the myometrium. The leiomyoma and prolapse were associated with necrotizing exposure endometritis. This is the first report of a uterine prolapse associated with a leiomyoma in a cetacean. This lesion was believed to be the underlying cause of the live stranding.

O prolapso de vesícula urinária associado ao prolapso uterino é condição rara em cães e gatos. O tratamento preconizado para essa afecção é o reposicionamento anatômico das estruturas afetadas. No presente relato é descrito o manejo por meio de ovariossalpingo-histerectomia por celiotomia e, após dois dias, cistopexia videoassistida. Essa condição, conforme o conhecimento dos autores, não havia sido previamente descrita. A operação apresentou-se como possibilidade viável de tratamento, sem complicações pós-operatórias.(AU)
The urinary bladder prolapse associated with the uterus is a rare condition on dogs and cats. The recommended treatment is the anatomical repositioning of the affected structures by manual reduction or surgery procedure. The present report describes the management by video-assisted cystopexy two days after conventional ovariohysterectomy. This condition, according to the authors' knowledge, had not been previously described. The operation didn't showed postoperative complications, and presented itself as a viable treatment option.(AU)

Vaginal prolapse is a condition characterised by excessive accumulation of mucosal oedema and protrusion of hyperplastic tissue through the vulva. It has been reported in ruminants and canines, but has not been characterised in felines. This report describes the history, clinical signs and treatment of a pregnant Maine coon cat with a Type III vaginal prolapse diagnosed approximately 54 days after the first day of mating. Prior to queening, the prolapse was reduced and retained using a vulvar cruciate suture. Due to the risk of dystocia and recurrence, a caesarean section with ovariohysterectomy was performed. Postoperatively, a stay suture was maintained in the vulva for 2 weeks, resulting in permanent reduction of the vaginal prolapse. To the authors' knowledge, this case represents the first report of the successful management of vaginal prolapse in a pregnant cat.

AIMS: Identify environmental, animal, and management factors associated with risk of vaginal prolapse in ewes, to enable farmers and advisors to make pragmatic decisions based on empirical observations for control of the condition. METHODS: Two longitudinal studies conducted over 2 years to identify factors associated with incidence of prolapse in (i) cohorts of 200 individually identified mixed-age (MA) ewes, and (ii) all MA ewes, on voluntarily participating sheep-breeding farms in Hawkes Bay (HB) and Southland regions of New Zealand. RESULTS: The overall annual incidences of prolapse on 113 farms in 2000 and 88 in 2001 were 1.21 and 0.82 per 100 MA ewes, respectively, and 1.05 for both years combined. A total of 406 prolapses were recorded among 36,695 individually identified cohort ewes. Individual farm incidences for both years varied from 0-5.9 (mean=1.56, median=1.39) on Southland and 0-3.9 (mean=0.75, median=0.54) per 100 ewes on HB farms. The crude relative risk of a prolapse occurring in a MA ewe was 5.31 times higher for ewes carrying twins and 11.3 times higher for ewes carrying triplets, than single lambs. Flocks made up of predominantly pure or crossbred Perendale ewes appeared to be at lower risk than flocks with other breeds. Shearing in the 3 months leading up to mating appeared to be protective, as was shearing in the second half of pregnancy. The risk was higher on farms with moderate to steep terrain than on farms with flat terrain. The identified risk factors in the individually identified cohorts were: access to salt and feeding of swedes in the latter part of pregnancy, moderate to steep lambing paddocks, multiple lambs detected at scanning, and weight gain between start of mating and scanning. The condition recurred in 2001 in six (35%) of 17 study ewes that had prolapsed during 2000. Culling policies for female offspring of affected ewes did not influence incidence at the farm level; nor did feeding hay or grain in late pregnancy. Furthermore, there was no association between incidence and body condition scores measured prior to and after mating, at scanning, or at time of set stocking. CLINICAL SIGNIFICANCE: Vaginal prolapse is an inevitable consequence of sheep reproduction and its incidence is expected to increase as reproductive rates increase. This study provides some firm leads as to the relative importance of risk factors and gives guidance for risk reduction, e.g. by identification and separate management of ewes carrying twins or triplets, using flat paddocks for lambing, and guarding against gain in weight between the start of mating and scanning.
