[Two cases of crossed renal ectopia without fusion].
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.
