A radiothermometer has made it possible to take deep temperature directly from the kidney. Comparison of temperatures, obtained from normal nonpregnant women, normal pregnant women and pregnant patients with acute pyelonephritis has demonstrated a significant drop in renal temperature during pregnancy. In acute pyelonephritis, renal temperature drops still further, with the temperature difference between the affected kidney and the contralateral one ranging from 0.5 degrees to 1.5 degrees. Deep temperature measurements of each kidney are taken from several sites, selected at ultrasonic scanning, which makes it possible to calculate temperature variance for the kidney. Variance increases significantly (more than two-fold) in the inflamed kidney, as compared to the intact one. Therefore, the diagnosis of acute pyelonephritis can be made where deep temperature difference is between 0.5 degrees and 1.5 degrees and temperature variance is increased twofold or more in one kidney, as compared to the other, in a pregnant patient. The side of affection is also determined in this way. The proposed diagnostic method is perfectly safe for the mother and the fetus, and can be used for the diagnosis of acute pyelonephritis during pregnancy, along with other procedures.
一种放射温度计使得直接从肾脏获取深部温度成为可能。对正常未怀孕女性、正常怀孕女性以及患有急性肾盂肾炎的怀孕患者的温度进行比较后发现，孕期肾脏温度显著下降。在急性肾盂肾炎中，肾脏温度进一步下降，患侧肾脏与对侧肾脏的温差在0.5度至1.5度之间。通过超声扫描选择几个部位对每个肾脏进行深部温度测量，这样就可以计算出肾脏的温度方差。与未发炎的肾脏相比，发炎肾脏的方差显著增加（超过两倍）。因此，对于怀孕患者，如果一个肾脏与另一个肾脏的深部温差在0.5度至1.5度之间，且温度方差增加两倍或更多，就可以诊断为急性肾盂肾炎。同时，也可以用这种方法确定患侧。所提出的诊断方法对母亲和胎儿完全安全，并且可以与其他检查方法一起用于孕期急性肾盂肾炎的诊断。
