Ectopic kidney occurs as a result of a halt in migration of kidneys to their normal locations during embryonal period. While kidneys ascend through pelvis, they receive new branches from vessels (iliac and aorta) close to them. When they reach the highest point, they receive new branches from aorta and the former branches degenerate. Renal vessels do not degenerate in the ectopic caudal kidney, more than one accessory and polar arteries may arise. In various studies, a possibility of association between presence of multiple renal arteries and hypertension, has been reported. We aimed to present a case with bilateral ectopic kidney and vascular anomaly associated with hypertension and renal dysfunction.
异位肾是由于胚胎期肾脏向正常位置迁移过程中受阻所致。当肾脏通过骨盆上升时，它们会从靠近它们的血管（髂血管和主动脉）获得新的分支。当它们到达最高点时，它们会从主动脉获得新的分支，而先前的分支会退化。在异位尾侧肾中，肾血管不会退化，可能会出现不止一条副肾动脉和极动脉。在各种研究中，已经报道了多条肾动脉的存在与高血压之间存在关联的可能性。我们旨在介绍一例伴有双侧异位肾以及与高血压和肾功能不全相关的血管异常的病例。
