ABSTRACT

O objetivo deste trabalho foi padronizar a técnica de acesso à pelve renal por meio de sondagem ureteral guiada por cistoscopia em éguas. Foram utilizados oito animais, de raças variadas, com peso médio de 439kg. As éguas foram sedadas e mantidas em tronco de contenção para a realização da cistoscopia com endoscópio flexível. Após identificação do óstio ureteral esquerdo, uma sonda de polietileno foi introduzida em seu lume, até a pelve renal. A localização da sonda no rim foi confirmada por meio de ultrassonografia transcutânea. Foram coletados 3mL de urina, de forma asséptica, para citologia e cultura bacteriana. Todas as amostras obtiveram resultados negativos na cultura e análise do sedimento urinário. Nenhum dos animais apresentou quaisquer complicações após a sondagem. Este estudo demonstrou que a coleta de urina diretamente da pelve renal em éguas, com auxílio da cistoscopia na realização da sondagem ureteral, consiste em um procedimento viável e seguro.(AU)


The objective of this study was to standardize the technique of access to the renal pelvis by means of ureteral catheterization guided by cystoscopy in mares. Eight animals of different races were used, with an average weight of 439kg. The mares were sedated and contained in containment trunk for the accomplishment of cystoscopy with flexible endoscope. After the identification of the left ureteral ostium, from where inside a catheter was introduced, which went through the entire extension of the ureter up to the renal pelvis. After identification of the left ureteral ostium, from where inside a catheter was introduced, into its lumen until reaching the renal pelvis. The location of the probe in the kidney was confirmed by transcutaneous ultrasonography. Three ml of urine was aspirated aseptically for cytology and microbiological culture. All the samples obtained negative results in the culture and sedimentation. None of the animals had any complications after catheterization. This study demonstrated that the collection of urine directly from the renal pelvis in mares, with the assistance of cystoscopy in the realization of the ureteral catheter, consists of a viable and safe procedure.(AU)

ABSTRACT

A inseminação artificial (IA) proporciona melhoramento genético, intensifica o manejo animal e possibilita a utilização de sêmen de reprodutores que se encontram em diferentes regiões do país, bem como de animais de alto valor zootécnico que já morreram ou de machos que possuem subfertilidade. Por peculiaridades anatômicas das ovelhas, a inseminação artificial intrauterina transcervical é dificultosa. Dessa forma, bons resultados na IA são alcançados quando há deposição do sêmen diretamente dentro do útero, realizada por meio de laparoscopia. Atualmente, diversas técnicas laparoscópicas são utilizadas para inseminação; os métodos rotineiramente empregados são realizados através de dois ou três portais de acesso. O presente trabalho tem o objetivo de verificar a viabilidade de uma nova técnica de inseminação videolaparoscópica intrauterina em ovelhas, com o uso de um acesso único, visando a um procedimento mais eficaz, mais rápido, com menor trauma tecidual e com menor contaminação bacteriana, a fim de minimizar o desconforto pós-operatório. A média do tempo cirúrgico foi de 5,92 minutos. Não foram encontradas dificuldades para realização dos procedimentos, e os animais recuperaram-se sem nenhuma complicação. A utilização de um único acesso mostrou-se eficaz, pois reduziu o tempo cirúrgico e não apresentou complicações.(AU)


Artificial Insemination (AI) provides genetic gain, enhances animal management and enables the use of semen from rams that are in different regions of the country, high-value livestock animals that have died or males who have subfertility. Because of anatomical peculiarities of sheep, transcervical intrauterine insemination is troublesome, thus good results in IA are achieved when there is deposition of semen directly into the uterus, performed by laparoscopy. Currently, various techniques are used for laparoscopic insemination, those routinely employed are conducted using two or three access portals. This study aims to verify the feasibility of a new laparoscopic intrauterine insemination in sheep using a single access, aiming at a more effective and faster procedure with less tissue trauma, minimizing post-operative discomfort and lower bacterial contamination. The mean operative time was 5,92 minutes, there were no difficulties in the procedures and the animals recovered without complications. The use of a single access was effective, reducing the time of the surgery and complications weren't observed.(AU)

ABSTRACT

This paper describes a case of malignant melanoma in brown coat horse, which had ataxia and proprioceptive deficits in hind limbs, progressing to permanent decubitus. The animal was euthanized and the final diagnosis was based on necropsy and histopathology. At necropsy different masses and / or nodules in skeletal muscle, bone, abdominal cavity, lungs, heart, spleen, liver, adrenal gland, lymph nodes, brain and cerebellum were found. Neurological clinical signs presented by the animal were justified by spinal cord compression caused by melanocytic mass invading the medullary canal of the flow segment of the thoracic spine (between 15th and 18th thoracic vertebrae). This is the first case report of melanoma leading to spinal cord compression in a non-gray horse. Thus, it is important to include this neoplasm in the differential diagnosis list of cutaneous and subcutaneous masses and / or nodules, and in suspected cases of spinal cord compression in horses of any coat.(AU)
