Outcome and Prognosis
The prognosis depends on the etiology of the fistula. For benign processes, the prognosis is generally good provided sepsis is absent or limited and the entity is recognized quickly.
Malignancy that is sufficiently advanced to cause a renoalimentary fistula carries a poor prognosis. This is not due to the fistula itself, but because of the tumor.
Future and Controversies
Renoalimentary fistula will likely remain an occasional sequela of percutaneous nephrostomy tube placement, but management is relatively straightforward. With percutaneous radiofrequency ablation and cryoablation becoming a more popular and viable treatment option, patients should be aware that renoalimentary fistula is a potential complication of them. The use of hydrodissection during radiofrequency ablation with normal saline and vigilance of surrounding structures during these procedures should help keep the development of fistulae to a minimum.
In many cases, renoalimentary fistulae are secondary to neglected treatment of chronic disease. Continued efforts at early diagnosis and treatment of underlying problems should decrease the incidence of renoalimentary fistulae and improve the prognosis.
