Complete renal fusion without crossed renal ectopia denotes the medial fusion of the renal parenchyma (with or without changes in the microarchitecture) in the pelvis with anteriorly placed short ureters terminating into the bladder. This could be due to the failure of renal analgen to ascent, lateral migration, axial rotation, and persistence of primitive vascular supply. Though remain asymptomatic such cases warrant concomitant congenital anomalies of other organ systems as well as the microarchitecture changes in the renal parenchyma.
完全性肾融合而无交叉异位肾是指肾实质（无论微观结构有无改变）在盆腔内的内侧融合，伴有前方位置较短的输尿管，其末端开口于膀胱。这可能是由于肾原基未能上升、侧向迁移、轴向旋转以及原始血管供应持续存在所致。尽管这些病例通常无症状，但仍需关注其他器官系统是否存在先天性异常以及肾实质的微观结构变化。
