title: Long-term results of the treatment of complete distal ureteral stenosis using a cutting balloon catheter device.
abstract: OBJECTIVE
  We evaluated the long-term efficacy of endoscopic treatment of complete distal ureteral stenosis using a cutting balloon catheter.
  
  
  METHODS
  We performed a total of 10 procedures in 9 patients with complete distal ureteral stenosis at or near the ureterovesical junction. Depending on presenting anatomy cases were treated with a retrograde only (6), antegrade only (1) or combined antegrade and retrograde (3) endoscopic technique.
  
  
  RESULTS
  At a mean followup of 36 months (range 24 to 43) 9 of the 10 procedures (90%) were successful. Stenosis recurred in 1 of the 9 patients (10%) but a repeat procedure was successful. There were no intraoperative complications and no procedures required open surgical conversion. Although all patients noticed a various degree of hematuria postoperatively, none required blood transfusion or further intervention. Mean hospitalization was 1.1 days.
  
  
  CONCLUSIONS
  Endoscopic repair of distal ureteral stenosis using a cutting balloon catheter is a viable option in patients with complete ureteral obstruction. This technique results in low morbidity, a short hospital stay and excellent long-term patency. Endoscopic treatment using a cutting balloon catheter may be a therapeutic option in many patients with complete distal ureteral obstruction at or near the ureterovesical junction.
