title: Retrograde ureteral intussusception: a rare complication.
abstract: A 45-year-old man with a history of cyclophosphamide exposure underwent repeated ureteroscopy for positive urine cytology findings after resection of a Grade 2 papillary transitional-cell carcinoma of the bladder. Despite careful technique, an intussusception developed in the left ureter, which was repaired by resection and construction of a Boari flap. To our knowledge, this is the first report of retrograde ureteral intussusception caused by ureteroscopy.
