摘要
目的：探讨大剂量静脉肾盂造影在输尿管阴性结石体外碎石中的应用效果。方法将86例输尿管阴性结石的患者按随机数字表法分为对照组和观察组，每组43例。对照组采用输尿管逆行插管造影定位联合体外冲击波碎石术（ESWL）治疗；观察组采用大剂量静脉肾盂造影定位联合ESWL治疗。对2组患者的排石情况及并发症（肾绞痛、血尿）发生率进行比较。结果2组患者在经一次碎石后2～20 d内均有不同程度的“细沙样”结石排出体外。2组患者一次治疗后结石的排净率比较差异无统计学意义（P＞0.05）。观察组和对照组分别有4例（9.30%）和5例（11.6%）体外排石失败改行腔内碎石术治疗；观察组发生并发症3例（肾绞痛2例、血尿1例，6.97%），对照组发生并发症4例（肾绞痛2例、血尿2例，9.30%），2组体外碎石失败率及并发症发生率的比较差异均无统计学意义（均P＞0.05）。结论大剂量静脉肾盂造影下行输尿管阴性结石ESWL治疗，结石排净率高、安全可靠，是治疗输尿管阴性结石的良好选择。
Objective To evaluate the efficacy of high dose intravenous urography in extracorporeal shock wave lithotripsy （ESWL） for radioparent calculus in the ureter. Methods A total of 86 patients with ureteral radioparent calculus were randomly assigned to receive ESWL combined with either retrograde ureteral catheterization（control group, n=43） or high dose intravenous urography（observation group, n=43）. The efficacies and complications（renal colic and hematuria） were compared between the two groups. Results Sand-like stones were excreted during 2-20 days after ESWL in both groups. There were no significant differences in the stone clearance rate between the two groups （P〉0.05）. Intracavitary lithotripsy was performed due to the failure of ESWL in 4 patients （9.30%） in control group and in 5 patients （11.6%） in observation group. The incidence of complications was 6.97% in observation group（renal colic in 2 and hematuria in 1） and 9.30%in control group（renal colic in 2 and hematuria in 2）. There were no significant differences in failure rate of ESWL and incidence of complications between the two groups （P〉0.05）. Conclusion The combination of high dose intravenous urography and ESWL is a safe and reliable treatment with a high stone clearance rate for radioparent calculus in the ureter.
