In comparison with pyeloplasty, endourologic procedures for the treatment of ureteropelvic junction obstruction offer good success rates with less morbidity and a shorter hospitalization; however, studies have found lower success rates and increased complications in patients with crossing vessels. Conventional diagnostic angiography and intravenous urography have both been used to identify crossing vessels at the UPJ; but, a reliable, less invasive, less costly, and simpler preoperative procedure to identify crossing vessels is needed. Helical CT with CT angiography is a promising noninvasive technique for the identification of crossing vessels at the ureteropelvic junction, which can be used for surgical planning of endourologic treatment of UPJ obstruction.
与肾盂成形术相比，用于治疗输尿管肾盂连接部梗阻的腔内泌尿外科手术成功率高，发病率低，住院时间短；然而，研究发现，有交叉血管的患者成功率较低，并发症增加。传统的诊断性血管造影和静脉肾盂造影都曾用于识别输尿管肾盂连接部的交叉血管；但是，需要一种可靠、侵入性小、成本低且操作简单的术前程序来识别交叉血管。螺旋CT血管造影是一种很有前景的无创技术，可用于识别输尿管肾盂连接部的交叉血管，可用于输尿管肾盂连接部梗阻腔内泌尿外科治疗的手术规划。
