| Abstract: | This is a report of two cases of a fistula between the urinary and gastrointestinal tracts. One case was a 56-year-old female patient with a right pyeloduodenal fistula, and the other was a 38-year-old female with a left ureterodescending colon fistula. The chief complaint was right lumbago in the first case, and fever and left lumbago in the second case. Both cases were diagnosed by retrograde pyelography. In both cases, the ailing kidney appeared to be non-functioning, and the former was operated by nephrectomy, fistulectomy, and duodenectomy in the cuneate form, while the latter was operated by nephrectomy and fistulectomy. The cause of the formation of the fistula was considered to be chronic pyelonephritis accompanied by renal stones in the first case, and rupture of the colon diverticulitis in the second case. Postoperative prognosis was satisfactory in both cases. |
