Among congenital renal anomalies, crossed renal ectopia is relatively rare. We report two cases of crossed renal ectopia without fusion. One patient was a 26-year-old woman, admitted to our hospital with complaint of infertility. She was diagnosed to have hydrosalpinx on hysterosalpingography. Intravenous pyelography and renoscintigraphy disclosed crossed renal ectopia without fusion. We confirmed it on the operation of hydrosalpinx. The other was a 28-year-old man with complaint of hypospadia. Intravenous pyelography, retrograde pyelography and abdominal aortography disclosed crossed renal ectopia without fusion. These patients had subjectively no complaints, and the renal functions were unimpaired. So we decided to follow them up. In Japan there have been 30 reports of crossed renal ectopia including these cases. We performed a statistical study of the renal ectopia without fusion.
在先天性肾脏异常中，交叉异位肾相对少见。我们报告两例未融合型交叉异位肾病例。一例患者为26岁女性，因不孕前来我院就诊。子宫输卵管造影显示其患有输卵管积水。静脉肾盂造影和肾闪烁显像显示为未融合型交叉异位肾。在输卵管积水手术中得以证实。另一例是一名28岁男性，因尿道下裂前来就诊。静脉肾盂造影、逆行肾盂造影和腹主动脉造影显示为未融合型交叉异位肾。这些患者主观上无不适，肾功能未受损。因此我们决定对其进行随访。在日本，包括这些病例在内，已有30例交叉异位肾的报告。我们对未融合型肾异位进行了统计学研究。
