Perirenal Effusion in Dogs and Cats With Acute Renal Failure

Abstract: Perirenal fluid accumulation has been described as an ultrasonographic feature of urine leakage, hemorrhage, abscessation, or neoplasia. The purpose of this retrospective study was to report perirenal effusion as an additional ultrasonographic finding in canine and feline patients with acute renal failure. The causes of acute renal failure in 18 patients included nephrotoxicity (4), leptospirosis (3), ureteral obstruction (2), renal lymphoma (2), ureteronephrolithiasis (2), prostatic urethral obstruction (1) a… Show more

“…Renal or ureteral calculi usually produce intense hyperechoic foci with strong acoustic shadowing on images of the kidney or ureter 29,33,60,73,99,100,102,103,120,121 (Figure 16-24). However, visualization may be obscured by overlying bowel gas.…”

“…Most calculi are sufficiently radiopaque for their presence to be confirmed on survey radiographs. of shadowing or a mass in this region suggests obstruction by a stricture 121,125 or blood clot, 87 although small calculi may shadow poorly. Although ultrasonography is accurate for urolith identification, survey radiographs provide additional information, including shape and opacity, which help determine mineral composition.…”

“…Uma das principais alterações ultrassonográficas que pode ser vista na lesão tubular aguda é a nefromegalia, que resulta de diferentes processos fisiopatológicos como o edema, infiltração inflamatória e hipertrofia compensatória (HOLLOWAY & O'BRIEN, 2007;LANGSTON & HEYTER, 2009;ROSS, 2011). O grau do aumento associa-se à severidade da lesão renal e, geralmente, é bilateral (MONTEIRO & FROES, 2009).…”

“…A pielectasia (Figura 2) pode ocorrer na pielonefrite aguda em cadelas com piometra (SANTOS et al, 2013), em decorrência de infecção ascendente do trato urinário inferior e em cães experimentalmente infectados (D'ANJOU et al, 2011). Dilatação pélvica renal discreta a moderada também tem sido observada em cães com leptospirose aguda (HOLLOWAY & O'BRIEN, 2007;D'ANJOU et al, 2011;LUNN, 2011) e insuficiência renal aguda devido ao aumento da produção de urina na poliúria e obstrução parcial por debris celulares (MONTEIRO & FROES, 2009). Embora a pelve renal não seja visualizada em rins normais, diurese salina também pode causar pielectasia moderada de até 3,0 mm, às vezes unilateral, em cães (NYLAND & MATTOON, 2005;D'ANJOU et al, 2011), portanto o uso de diurético ou pacientes submetidos a fluidoterapia devem ser considerados durante a avaliação.…”
