88例肾盂输尿管连接部梗阻的诊治

目的：通过对88例肾盂输尿管连接部梗阻（PUJO）静脉肾盂造影（IVU）结果，为早期诊断PUJO提出确切依据。方法：88例病人均进行IVU或逆行造影，手术治疗83例共98侧，58例术后病理切片。结果；88例术前后诊断均完全符合。提出了早、中期PUJO在IVU上独特的影像学表现是以肾盂饱满或扩张为主，而肾盏扩张多不明显为特点，与肾结石所致肾积水有明显区别。结论：治疗仍以Anderson-Hynes离断性肾盂成形术为好。

Diagnosis and Treatment for Obstruction at Ureterpelvic Junction

Objective:To provide precise basis for the early diagnosis of obstruction at ureterpelvic junction (PUJO).Methods: Intravenous pyelography (IVP)was used to examine 88 patients. 83 of them with totally 98 sides accepted operation, and 58 sides were examined pathologically after the operation.Results:The results showed a 100% conformation of the per and post operation diagnsis, and showed that the IVP characteristics of early and middie stages of PUJO were mainly fullness or dilation of renal pelvis, while calyectasis was not obvious. And It is distinctly different from those IVP of hydronephrosis caused by stone.Conclusion:It is recommended to use Anderson Hynes operation when cutting off pelvis.
