Our objective was to compare the value of endoluminal sonography with the value of helical CT in the preoperative assessment of crossing vessels in patients with ureteropelvic junction (UPJ) obstruction.
Thirteen patients with UPJ obstruction underwent contrast-enhanced helical CT with multiplanar reformations and endoluminal sonography. Imaging preceded surgery for UPJ repair. On imaging, vessels were considered significant if greater than or equal to 2 mm in diameter and within 1 cm of the UPJ.
Three patients had no crossing vessels revealed by either study. On sonography, another patient had a vessel revealed with a diameter that varied between 1.3 and 2.2 mm; on CT no correlate was detected. The remaining nine patients had vessels revealed by both techniques. On CT, four patients had two vessels revealed and five patients had single vessels revealed for a total of 13 vessels revealed by CT. On sonography, five patients had two vessels revealed and five patients had single vessels revealed. Thus, 15 vessels were revealed by sonography. Both arteries and veins were revealed anterior, posterior, and medial to the UPJ; no lateral vessels were seen. Four patients underwent laparoscopy, during which the absence, presence, and location of vessels were found to correlate with sonography and helical CT.
Endoluminal sonography and helical CT were similar in revealing crossing vessels in patients with UPJ obstruction.
我们的目的是比较腔内超声与螺旋CT在术前评估输尿管肾盂连接部（UPJ）梗阻患者交叉血管方面的价值。
13例UPJ梗阻患者接受了对比增强螺旋CT多平面重建及腔内超声检查。成像检查在进行UPJ修复手术之前。在成像检查中，直径大于或等于2mm且位于UPJ 1cm范围内的血管被视为有意义。
两项检查均未发现3例患者有交叉血管。在超声检查中，另1例患者发现有1条血管，其直径在1.3至2.2mm之间变化；CT检查未发现相应情况。其余9例患者两种检查均发现有血管。在CT检查中，4例患者发现有2条血管，5例患者发现有1条血管，CT总共发现13条血管。在超声检查中，5例患者发现有2条血管，5例患者发现有1条血管。因此，超声检查发现15条血管。UPJ前方、后方及内侧均发现有动脉和静脉；未发现外侧血管。4例患者接受了腹腔镜检查，在此过程中发现血管的有无及位置与超声检查和螺旋CT检查结果相符。
腔内超声和螺旋CT在显示UPJ梗阻患者交叉血管方面相似。
