“…The remodeling and the repairing of the operated tissue is directly related to the diameter of the suture material [26], so, with the exception of the renal width at the 30th day, it is possible to observe that, in the two ultrasound evaluations, the renal measurements developed largest changes according to the greater caliber of the suture used. In relation to the renal pelvis, when there is no dilation, this structure is not normally seen on ultrasound and subtle dilations may also go unnoticed [23,27]. The dilation indices obtained in this study corresponded to the ureteral dilation seen in the ultrasound exams, in which the N8 had the largest ureteral diameters in the rst exam and all animals in this group presented the pelvis dilated.…”

“…The other two groups showed decreasing changes for pelvic dilation and ureteral diameter, according to the thickness of the suture material used (4 animals in N6 and 3 in N10). At 30 days, these two parameters decreased in all groups, particularly in N6 due to the loss of experimental plots, rea rming that the increase in measurements occurs mainly due to acute changes [11,27].…”

“…The ureters follow the pattern of the renal pelvis and are only seen on ultrasound when they are dilated [3,7,27,28] and the group operated with 8.0 suture was the only one that developed a signi cant increase in diameter in the rst ultrasound assessment. The animals in this group also had high scores for ureteral in ammation, presence of stenosis and dilation at the suture site, in addition to macroscopic renal changes in greater numbers.…”

Background Ureteral obstruction is a common indication for surgical intervention, due to the small size of the ureter, specialized instrumentation is required such as operating microscope for intraoperative magnification and microsutures. The aim of this study is to evaluate and compare 3 sizes of nylon 6 − 0,8 − 0,10 − 0 for ureterorrhaphy in the ureter of rabbits, using microsurgical technique. Results A total of fifteen male, adults, New Zealand rabbits were divided in three groups: all groups were submitted ureterotomy. A 2 mm longitudinal incision was made in the medial portion of the right ureter, followed by a partial perforating simple interrupted 6 − 0, 8 − 0 and 10 − 0 sutures in each group. During the experiment ultrasound evaluations were performed to assess the kidney length and width, the presence of ureteral calculi, the renal pelvic dilation, the ureter diameter and the presence of free liquid in the abdominal cavity. At the end of the experiment all kidneys and ureters were submitted to macroscopic and histopathological evaluations. In the first ultrasound assessment, all groups had an acute increase in renal length (p < 0.048). The group with 8 − 0 suture showed a difference in ureteral diameter on the 5th day (p < 0.01) and all groups showed a reduction in diameter on the 30th day. The group with 6 − 0 suture showed a high mortality rate during the experimental period and the histopathological evaluation exhibited areas of necrosis. According to the ultrasound evaluation caliber 10 − 0 achieved better results in, macroscopic and microscopic evaluations. The finer suture diameters had better outcomes according to the ureteral inflammation scores. Conclusions The use of 10 − 0 suture resulted in lower rates of ureteral inflammation, renal changes and postoperative complications when compared to two other sizes of the same material.

“…Ultrasonic examination of the kidneys and urinary tract allows visualisation of renal parenchymal abnormalities, renal pelvic and ureteral dilation, renal blood flow abnormalities, infarcts, cysts, mineralisation and uroliths and helps achieve a diagnosis of pyelonephritis, lymphoma or ethylene glycol toxicosis (Rivers & Johnston 1996 , Lamb 1998 , Debruyn et al . 2012 ). The biggest limitation to ultrasonic evaluation is its lack of sensitivity to minor alterations in the anatomy of renal pelvises and ureters (Lamb 1998 ).…”

OBJECTIVESThere is a growing understanding of the complexity of interplay between renal and cardiovascular systems in both health and disease. The medical profession has adopted the term “cardiorenal syndrome” (CRS) to describe the pathophysiological relationship between the kidney and heart in disease. CRS has yet to be formally defined and described by the veterinary profession and its existence and importance in dogs and cats warrant investigation. The CRS Consensus Group, comprising nine veterinary cardiologists and seven nephrologists from Europe and North America, sought to achieve consensus around the definition, pathophysiology, diagnosis and management of dogs and cats with “cardiovascular-renal disorders” (CvRD). To this end, the Delphi formal methodology for defining/building consensus and defining guidelines was utilised.METHODSFollowing a literature review, 13 candidate statements regarding CvRD in dogs and cats were tested for consensus, using a modified Delphi method. As a new area of interest, well-designed studies, specific to CRS/CvRD, are lacking, particularly in dogs and cats. Hence, while scientific justification of all the recommendations was sought and used when available, recommendations were largely reliant on theory, expert opinion, small clinical studies and extrapolation from data derived from other species.RESULTSOf the 13 statements, 11 achieved consensus and 2 did not. The modified Delphi approach worked well to achieve consensus in an objective manner and to develop initial guidelines for CvRD.DISCUSSIONThe resultant manuscript describes consensus statements for the definition, classification, diagnosis and management strategies for veterinary patients with CvRD, with an emphasis on the pathological interplay between the two organ systems. By formulating consensus statements regarding CvRD in veterinary medicine, the authors hope to stimulate interest in and advancement of the understanding and management of CvRD in dogs and cats. The use of a formalised method for consensus and guideline development should be considered for other topics in veterinary medicine.
