肾包膜下积液19例临床分析

目的探讨肾包膜下积液的成因和治疗方法。方法回顾分析19例肾包膜下积液，其中12例因尿路梗阻，4例因肾实质感染而形成；3例原因不明。均经CT明确诊断。结果19例肾包膜下积液中，15例针对病因治疗，即解除梗阻，控制肾实质感染后，积液均有吸收减少；原因不明予以对症治疗。积液亦被吸收。结论尿路梗阻是肾包膜下积液的常见原因，增高的肾盂压力使得尿液经静脉、淋巴管或直接返流到肾周；急性肾绞痛因肾盂压力的急剧升高，更易形成包膜下积液。肾实质的感染也是形成积液的重要原因。在对因治疗，解除梗阻，控制感染后，肾包膜下积液均可逐渐被吸收。

Clinical analysis of 19 cases of renal snbeapsular hydrops

Objective To study the causes and the treatment of renai subcapsular hyrops. Method 19 cases were reported. 12 cases were concerned with urinary tract obstruction,4 cases with renal parenchyma infection and 3 cases with unclear reason. An subjects were identified by CT scan. Resolts The hydrops was absorbed and decreased after treatment of the obstruction and effective control of the infection. Conclusion Hy-drops must be differentiated clinically from hematocele. Urinary tract obstruction is the common cause of renal subcapsular hydrops .On account of the increased pelvis pressure,the urine reilux. occur directly or through the veins and lymph traets. Hydrops is casilier occur in acute renal colic with accompanying rapid increasing pelvis pressure. Infection of renal parenchyma may be one of important cause of hydrops. Relief of the obstruction or control of the infection is the best way to treat hydrops instead of special managements.
