Abstract

Early detection of renal deficient function is imperative for the success of treatments and determining prognosis. In horses, a renal ultrasound can be performed through the abdominal wall (TA) or transrectally (TR), being an important tool for the evaluation of the kidneys. Besides renal morphology, resistivity (RI) and pulsatility indexes (PI) may be early tools to detect renal injury as they reflect arterial compliance. Twenty-nine healthy adult horses were sonographically evaluated by TA and TR approaches, measuring RI and PI on both kidneys. The mean values from the TA for RI and PI in the right kidney were, respectively, 0.577 ± 0.072 and 0.950 ± 0.182, and 0.553 ± 0.077 and 0.884 ± 0.163 in the left kidney. As for the TR, the mean values for RI and PI in the right kidney were 0.543 ± 0.096 and 0.848 ± 0.212, respectively, and 0.551 ± 0.089 and 0.888 ± 0.204 in the left kidney. No differences (two-way ANOVA) were observed between the left and right kidneys [RI (p = .31) and PI (p = .24)] nor between techniques for both RI and PI, being relevant to state that data on the right kidney by the TR technique did not allow a reliable statistical evaluation. Obtaining good quality TR images in larger horses and satisfactory TA images in obese horses were important differences for each examination technique. In conclusion, there were no differences in RI and PI values obtained from abdominal or transrectal approaches.

健康马的电阻率和脉动指数肾脏值在通过腹部或经直肠方法获得时没有差异。
早期发现肾功能不全是治疗成功和确定预后的必要条件。在马中,肾脏超声可以通过腹壁(TA)或经直肠(TR)进行,是评估肾脏的重要工具。除了肾脏形态学外,电阻率(RI)和脉搏指数(PI)可能是早期检测肾脏损伤的工具,因为它们反映了动脉顺应性。29匹健康成年马通过TA和TR方法进行超声评估,测量双肾的RI和PI。右肾RI和PI的TA平均值分别为0.577±0.072和0.950±0.182,左肾RI和PI的TA平均值分别为0.553±0.077和0.884±0.163。TR方面,右肾RI均值0.543±0.096,PI均值0.848±0.212,左肾RI均值0.551±0.089,PI均值0.888±0.204。左肾和右肾[RI (p = 0.31)和PI (p = 0.24)]之间没有差异(双向方差分析),RI和PI技术之间也没有差异,这与TR技术对右肾的数据不允许可靠的统计评估有关。在体型较大的马身上获得高质量的TR图像,在肥胖的马身上获得令人满意的TA图像是各检查技术的重要区别。总之,经腹入路和经直肠入路的RI和PI值没有差异。
