肾周积液的病因分析及超声应用价值

目的：分析肾周积液的不同原因，探讨超声在肾周积液中的应用价值。方法：回顾性分析43例肾周积液的原发病因及超声表现。结果：43例中急性尿路梗阻19例，急性胰腺炎8例，肾外伤6例，急性肾盂肾炎5例，腹膜后血肿4例，肝脏外伤1例。肾周积液超声表现：肾包膜下积液表现为肾包膜下与肾实质问新月形液性暗区；肾周间隙积液表现为脂肪囊增厚，肾周间隙内呈多片形态各异液性暗区。结论：超声对肾周积液原发病因诊断和病变转归及肾周积液吸收情况判断，具有很高的应用价值。

The etiological analysis and value of ultrasonography for perirenal effusion

Objective： To investigate the causes and value of uhrasonography for perirenal effusion. Methods： The causes and ultrasound features of 43 cases with perirenal effusion were retrospectively analyzed. Results：Among the 43 cases, acute urinary tract obstruction in 19 cases, acute pancreatitis in 8 cases, renal trauma in 6 cases, acute pyelonephritis in 5 cases, retroperitoneal hematoma in 4 cases and liver trauma in 1 case were found. The ultrasound feature of renal subcapsular effusion was crescent liquid dark area between renal capsule and renal parenchyma. The thickening adipose capsule was the manifestation of renal subcapsular effusion, and the liquid dark area in perirenal space was various multichip form. Conclusions：The ultrasound detection rate of perirenal effusion is high. Ultrasound can effectively find the primary lesions, dynamically observe the patient＇s condition and perirenal effusion absorption, which has high application value.
