肾盂输尿管连接部梗阻的手术治疗(附47例报告)

目的：探讨诊治肾盂输尿管连接部（ＵＰＪ）梗阻的新方法。方法：先天性ＵＰＪ梗阻患者４７例，术前诊断主要依靠电视下逆行肾盂造影和利尿性Ｂ超检查。外科治疗主要采用自行设计的双叶舌状肾盏壁瓣肾盂成形术。结果：Ｂ超和电视下逆行肾盂造影对ＵＰＪ梗阻的确诊率分别为８０．２％和１００％。双叶舌状肾盂壁瓣肾盂成形术后吻合口更通畅，无狭窄或漏尿并发症。结论：在ＵＰＪ梗阻的术前诊断中，电视下逆行肾盂造影明显优于ＩＶＵ。

Obstruction of ureteropelvic junction(Report of 47 cases)

Purpose: To investigate the new method of diagnosis and trearment for the obstruction ofureteropelvic junction (UP J). Methods:From 1993 to June 1999,47 cases of obstruction of UPJ have been treatedsugically with the diagnosis confirmed on histopathological studies. The preoperative diagnosis was usually madeon videocast retrograde pyelography and ultrasonography. In surgical treatment,the double tongue-shaped flaptype of pyeloplasty designed by us was specially undergone. Results:The accurate rate of ultrasonography andvideocast retrograde pyelography was 80. 2%and 100%. There were no post operative complication such asconstriction and uric leakage after the double tongue-shaped flap type of pyeloplasty. Conclusions: Forpreoperative diagnosis of obstruction of UPJ, ultrasonography was a better examination method. The doubletongue-shaped flap type of pyeloplasty designed by us was considered as a satisfactory effect,less complication,and should be recommendable for clinical application.
