盲管不完全重複尿管の1例

A CASE OF BLIND ENDING BIFID URETER AND A REVIEW OF THE LITERATURE

緒言

　盲管重複尿管（blind-ending bifid ureter）は，1947年Culpら^1）の定義が提唱されて以来，一般に使用されるようになつた尿管奇形である。われわれは本症の1例を経験したので報告するとともに，本邦61例を集計し統計的考察を加えた。

A 33-year-old man was admitted with a chief complaint of pyuria. Drip infusion pyelogram revealed the reflux to right blind-ending bifid ureter. The right retrograde pyelogram revealed a bifid ureter more clearly. The blind-ending bifid ureter was removed operatively, and then the ureterovesiconeostomy was done. The ureteral bifurcation at an acute angle was present approximately 5 cm above the right U-V junction. The blind-ending segment measured 8.9cm in length and 1 cm in greatest diameter. Histo-logically it was identical to normal ureteral tissue. Convalescence was uneventful and the patient expe-rienced no pyuria.
