We describe a case of a patient with a two-year history of prostate cancer who underwent placement of nephroureteral stents. He subsequently presented to the hospital with complications from prolonged retention of the stents, which ultimately lead to a secondary diagnosis of adenocarcinoma of the rectum. A colonoscopy performed approximately two weeks after a bilateral nephroureteral tube exchange demonstrated what was believed to be locoregional metastatic disease and a fistulous connection with the distal nephroureteral stents. Radiographic features of this complication are discussed together with proper management and possible complications of distal nephroureteral stents. Both nephroureteral stents were explanted, and nephrostomy catheters were sequentially replaced to allow for healing of the fistula.
