In order to assist endourologists in performing endopyelotomy safely and efficiently, we have made an anatomical study on the vascular relationships to ureteropelvic junction (UPJ). Our material consisted of 82 3-dimensional polyester resin corrosion endocasts of pelviocaliceal system together with intrarenal arteries and 52 casts of pelviocaliceal system together with intrarenal veins. Relationships to renal arteries: in 53.6% of the cases (44/82 casts) we found a close relationship between the inferior segmental artery and the anterior surface of the UPJ (among these, in 1 case, there was 1 artery anterior and 1 artery posterior to UPJ). In the other cases (38/82 casts), the UPJ was not related to arteries. Relationships to renal veins: in 40.4% of the cases (21/52 casts) we found a close relationship between an important tributary of the renal vein and the anterior aspect of the UPJ (among these, in 1 one case, existed 1 vein anterior and 1 vein posterior to UPJ). In the other cases (31/52 casts), the UPJ was not related to veins. Due to our findings, we can advise that UPJ must be incised just laterally, avoiding arteries and veins.
为协助腔内泌尿外科医生安全、高效地进行肾盂内切开术，我们对输尿管肾盂连接部（UPJ）的血管关系进行了解剖学研究。我们的材料包括82个肾盂肾盏系统连同肾内动脉的三维聚酯树脂腐蚀铸型，以及52个肾盂肾盏系统连同肾内静脉的铸型。与肾动脉的关系：在53.6%的病例（44/82个铸型）中，我们发现下段动脉与UPJ的前表面关系密切（其中，1例中UPJ前方有1条动脉，后方有1条动脉）。在其他病例（38/82个铸型）中，UPJ与动脉无关。与肾静脉的关系：在40.4%的病例（21/52个铸型）中，我们发现肾静脉的一条重要分支与UPJ的前侧关系密切（其中，1例中UPJ前方有1条静脉，后方有1条静脉）。在其他病例（31/52个铸型）中，UPJ与静脉无关。基于我们的研究结果，我们建议UPJ必须在外侧切开，避开动脉和静脉。
