摘　　要：目的探讨分次团注技术对迷走血管压迫所致肾盂输尿管连接部梗阻（UPJO）的诊断价值。方法52例UPJO患者采用分次团注技术扫描，观察有无迷走血管、迷走血管的起源及其与UPJO之间的关系，并与手术病理相对照。结果52例患者中，CT怀疑14例为迷走血管压迫所致，其中10例为左侧副肾动脉，1例为起源于左肾动脉的卵巢动脉，1例为右侧副肾动脉，2例为左侧性腺静脉，均与手术病理相吻合，敏感性和特异性均为100％。结论采用分次团注技术能准确对迷走血管压迫所致的UPJO患者做出病因诊断，以指导手术，并且减低了患者所接受的放射剂量。Objective To study the diagnostic value of contrast--enhanced CT scan with split bolus for the ureleropelvic junction obstruction（UPJO） caused by aberrant vessel of kidney. Methods 52 patients with UPJO underwent contrast--enhanced CT scan with split bolus. The aberrant vessels and its origin as well as the relationship between aberrant vessels and UPJO were observed comparatively with the results of surgery. Results In 52 cases,CT showed UPJO caused by aberrant vessl of kidney in 14 cases,including accessory renal arteries in 10, ovarian artery originated from left renal artery in one, right accessory renal artery in one and gonad veins in 2. CT findings were corresponded to operations in all these 14 cases. The sensitivity and specificity of CT in evaluating UPJO were 100% respectively. Conclusion The UPJO caused by aberrant vessel of kidney can be diagnosed accurately by contrast- enhanced CT scan with split bolus, which can be offered for surgical treatment for UPJO. The patient＇s CT dose can be decreased with split bolus.
