Abstract:
Spontaneous pyeloduodenal fistula is extremely rare. Most of the etiologies belong to chronic renal inflammatory disease, especially in patients with renal calculi. In published studies, only 2 cases have been reported in association with renal malignancy. We report a case of spontaneous pyeloduodenal fistula associated with transitional cell carcinoma, which has not been previously described in published reports.
