Results of diagnosing pyelonephritis in 106 patients using ultrasonography, CT and thermovision were analyzed. Purulent pyelonephritis (PP) was diagnosed in 57 patients, serous pyelonephritis--in 49 patients. The sensitivity of ultrasonography in the diagnosing of PP was more than 80%, that of CT--90%. The methods used allowed the 100% improvement of the differential diagnosis of renal abscess, apostematous nephritis and pyonephrosis. The greatest problems were met in the diagnosis of renal carbuncle which was detected in 50% of cases by ultrasonography and in 54% of patients by CT. The minimum sizes of the destruction focus when the diagnosis could be reliable were 2 cm for ultrasonography and 1.5 cm for CT. Only using the findings of CT could diagnose emphysematous pyelonephritis. Thermovision could not find any definite criteria of PP. The timely diagnosis of PP allowed the organ-saving operations to be fulfilled in the overwhelming amount of the patients. Positive results of the treatment using the above mentioned diagnostic methods were obtained in 98.8% of the patients.
分析了106例患者使用超声检查、CT和热成像诊断肾盂肾炎的结果。57例患者被诊断为脓性肾盂肾炎（PP），49例患者为浆液性肾盂肾炎。超声检查诊断PP的敏感性超过80%，CT为90%。所采用的方法使肾脓肿、脓性肾炎和肾积脓的鉴别诊断准确率提高了100%。肾痈的诊断遇到的问题最大，超声检查在50%的病例中检测到肾痈，CT在54%的患者中检测到。超声检查可靠诊断时破坏灶的最小尺寸为2 cm，CT为1.5 cm。只有通过CT检查结果才能诊断气肿性肾盂肾炎。热成像未发现PP的任何明确标准。PP的及时诊断使绝大多数患者能够进行保肾手术。使用上述诊断方法治疗的患者中98.8%获得了阳性结果。
