目的 总结由输尿管结石梗阻引起患侧肾脏不显影者行ESWL治疗的临床经验。 方法 输尿管结石致急性绞痛患者 16 8例 ,ESWL术前行KUB和IVU检查明确诊断输尿管结石而患侧肾脏不显影。结石位于髂骨缘以上者采用仰卧位 ,髂骨缘以下者采用俯卧位治疗。对 10 4例病史 <1个月、年龄 <6 0岁者于结石排空后行IVU ,观察其肾功能恢复情况。 结果 16 8例患者全部于 2周内排空结石 ,其中 10 4例在结石排空后 1周～ 1年复查IVU ,患侧肾均已显影 ,2例仍有肾盂轻度积水。 结论 输尿管结石急性发病时 ,可因肾内压力骤增而引起肾功能受损 ,表现为患侧肾不显影。这种损害是可逆的 ,及时解除梗阻可使患肾功能得到恢复 ,ESWL是有效措施之一
OBJECTIVE: To summarize the clinical experience of ESWL treatment in patients with idiopathic renal obstruction caused by ureteral calculi obstruction. Methods One hundred and sixteen patients with acute angina caused by ureteral calculi underwent ureteral calculi with KUB and IVU before ESWL. Stones located above the iliac edge using the supine position, the following ilium edge with prone position treatment. One hundred and forty-four patients with a history of <1 month, aged <60 years old, were treated with IVU after emptying of stones and the recovery of renal function was observed. Results All 168 patients were emptied of stones within 2 weeks. Among 104 cases, the IVU was rechecked from 1 week to 1 year after emptying of stones. The affected side kidneys were developed and 2 cases had mild hydronephrosis. Conclusions Acute ureteral calculi may result in impaired renal function due to sudden increase in renal pressure, manifesting as ipsilateral kidney not developing. This damage is reversible, timely relief of obstruction can make the recovery of renal function, ESWL is one of the effective measures
