Dislodged Nephrostomy Catheter: An Unusual Case of Idiopathic Transposition of Nephrostomy Catheter From Transplanted Kidney to Adjacent Small Bowel Loop: A Case Report.

A 72-year-old man with a past medical history notable for deceased renal transplant presented to the interventional radiology department for routine right lower quadrant renal transplant nephroureteral catheter exchange. The nephroureteral catheter was placed in 2016 because of the presence of a hematoma causing partial page kidney and hydronephrosis. An antegrade nephrostogram was notable for opacification of the small bowel instead of the renal collecting system. The patient then subsequently developed urinary retention and intractable abdominal pain. Because of the combination of events, it was deemed necessary for laparotomy and surgical repair of the small bowel. Intraoperative findings were notable for small bowel adhesion to the abdominal wall but otherwise no evidence of acute inflammatory changes. In this case report, we describe the first case of an idiopathically dislodged nephrostomy catheter to the small bowel from a transplanted kidney and its successful management.
