尿管自然破裂の2例

SPONTANEOUS RUPTURE OF THE URETER: REPORT OF TWO CASES

緒言

　尿管自然破裂はきわめてまれな疾患で，わが国でも報告例は少なく，現在までにその報告例は7例^1〜7）を数えるにすぎない。最近われわれはその2例を経験したので若干の文献的考察を加えて報告する。

The first case, a 59-year-old woman who had a history of right ureteral stones 15 years ago was seen with an abrupt onset of right flank pain. Urography revealed extravasation of contrast media around the upper portion of the right ureter which was interpreted as spontaneous rupture without stone. Severe inflammatory damage of the affected site of ureter resulted subsequent nephrectomy. The second case, a 34-year-old man was seen with a complaint of the sudden onset of left flank pain. Urography revealed a small stone at the P-U junction and extravasation of contrast media around the site.
