Efficacy and Safety of Ultrasound-guided Percutaneous Biopsy of the Right Kidney in Cattle

Abstract

ABSTRACT. The purpose of the present study was to develop a technique for biopsy of the kidneys of cattle and to evaluate its usefulness and safety based on 25 consecutive biopsies. Using a handheld 14G spinal biopsy needle, the right kidney was biopsied under ultrasound control by one operator. To assess the immediate effects of renal biopsy, twenty cattle were necropsied shortly after the procedure and examined. The remaining five animals were biopsied and examined daily for nine days and then necropsied. One pass was made for biopsy of the right kidney. No immediate or delayed macroscopic hematuria was observed post-biopsy. Six animals had a thin subcapsular hematoma (less than 2 cm in diameter). We conclude that percutaneous ultrasound-guided biopsy of the right kidney is safe, fast, cost-effective and practical as long as it is performed properly.

Hepatic ultrasonography in three breeds of healthy calves: Nellore, Curraleiro Pe‐duro and Pantaneiro

“…In the 12th intercostal, the kidneys were located on the liver window in approximately 80% of calves. Similar results (90%) were cited by Mohamed and Oikawa (2008) in non‐pregnant, non‐lactating and clinically healthy Holstein cattle.…”

“…The results of the ultrasonographic examination showed that in the 21 calves the right kidney had a normal appearance which was the renal cortex hypoechoic compared to the surrounding tissues, whereas the sinus was hyperechoic, as well described by Braun (1991), Seif and Bakr (2007), Mohamed and Oikawa (2008) and Floeck (2009). In additional, the presence of fat and fibrous tissue in the sinus was visualized in the paralumbar fossa (Floeck, 2009; Seif & Bakr, 2007).…”

Superficial swellings in camels (<i>Camelus dromedarius</i>): Clinical and ultrasonographic findings

“…In addition to providing animal comfort under field conditions, US is a noninvasive, safe, quick, simple, and reliable imaging technique for differential diagnosis of different superficial swellings [ 1 ]. Moreover, US detects the nature of the contents and enables precisely guided needle biopsy of the swellings, which can improve the ability of the camel practitioner to differentiate several superficial swellings [ 25 ]. According to the available literature, the use of US in diagnosing superficial swellings in camels is limited.…”

Ultrasonography of the Kidneys in Healthy and Diseased Camels (Camelus dromedarius)

“…If unrecognized or left untreated, hydronephrosis can lead to loss of renal function and sepsis. Consequently, all animals found to have hydronephrosis should undergo a thorough evaluation [ 11 ]. In cases of bilateral hydronephrosis, transrectal ultrasonography showed a distended urinary bladder, anechoic fluid in the uterus, and hydronephrosis of the left kidney.…”

“…In bovine, thoracic and abdominal ultrasonography is commonly performed to evaluate the type and severity of lesions in animals suspected to have cardiopulmonary, gastrointestinal, hepatic, renal, splenic, and pancreatic disease [ 4 – 10 ]. Therefore, ultrasonography of thoracic and abdominal organs in bovines is a minimally invasive and cost-effective method for early detection of thoracic and abdominal disorders [ 8 , 11 , 12 ].…”
