石灰化を伴った腎無形成の1例

Abstract

Renal agenesis seen in a 27-year-old man was reported. He came with chief complaint of left flank pain and transfered to us because of calcified shadow in the left renal area on KUB. Intravenous pyelography did not visualize pelvis, calyces or ureter on the left side. Retrograde ureterography showed the blind-ending ureter on that side. Aortography demonstrated left renal artery which was incomplete. Left nephrectomy was performed under the working diagnosis of contracted kidney with calcification. The specimen appeared as a cystic mass with partial calcification to which the artery, previously demonstrated by aortography, was observed to enter along with the renal vein. Postoperatively, his pain disappeared. Pathohistological examination proved it to be renal agenesis. Interestingly enough, electromyography recorded retrograde peristaltic discharge from the blind-ending ureter. In this patient, there were no other congenital abnormalities in the genitourinary tract or hypertension.
