Ultrasound examinations were analysed in 38 patients with acute renal infections (pyelonephritis, focal pyelonephritis, renal abscess, pyonephrosis). Ultrasound examination is normal in mild inflammatory involvement of parenchyma. In severe involvement diffuse enlargement of parenchyma with low density of echoes structure is found, while in focal pyelonephritis localized low density of echoes swelling of parenchyma is seen. Fever and flank pain are common to acute ureteral obstruction and acute pyelonephritis and ultrasound can distinguish between these diseases. Among mass lesions ultrasound can distinguish between focal pyelonephritis and abscess, but cannot differentiate between tumour and focal pyelonephritis.
对38例急性肾脏感染（肾盂肾炎、局灶性肾盂肾炎、肾脓肿、肾积脓）患者的超声检查结果进行了分析。在肾实质轻度炎症累及的情况下，超声检查结果正常。在严重累及的情况下，可发现肾实质弥漫性肿大，回声结构密度降低；而在局灶性肾盂肾炎中，可见肾实质局限性低回声肿胀。发热和胁腹疼痛是急性输尿管梗阻和急性肾盂肾炎的常见症状，超声可对这两种疾病进行鉴别。在肿块性病变中，超声可区分局灶性肾盂肾炎和脓肿，但无法鉴别肿瘤和局灶性肾盂肾炎。
