自然腎盂外溢流の2例

TWO CASES OF SPONTANEOUS PERIPELVIC EXTRAVASATION

緒言

　自然腎盂外溢流は，主に結石のような良性疾患による急激な尿路閉塞によつて生じることが多いと言われている。最近，われわれは，尿管結石によるものと思われる自然腎盂外溢流の2例を経験したので報告するとともに，若干の文献的考察を加えた。

The first patient was a 69-year-old man, who noted sudden onset of right abdominal pain without any episode of trauma. An excetory urograms demonstrated extravasation of contrast medium around the right renal pelvis. Exploratory laparotomy was performed with the suspicion of spontaneous rupture of the right renal pelvis. But no perforation was found in the pelvis. Indigo carmine solution injected intravenously appeared in the upper pole of the kidney. The patient was treated conservatively with indwelling ureteral catheter.
