title: Treatment of benign ureteral stricture by double J stents using high-pressure balloon angioplasty.
abstract: BACKGROUND
  Balloon dilatation angioplasty is a minimally invasive surgery for treating benign ureteral stricture. The aim of this study was to investigate the effect of placing double J (D-J) stents using high-pressure balloon angioplasty in treating benign ureteral stricture.
  
  
  METHODS
  A total of 42 patients (48 cases) with benign ureteral stricture (42 had benign ureteral stricture) were investigated by inserting dual D-J stents using high-pressure balloon angioplasty. The control group contained 50 patients (57 cases) employing the conventional balloon angioplasty with a single D-J stent inserted for comparison.
  
  
  RESULTS
  The overall effective rate of the treated and control groups was 87.8% (36/41) and 62.7% (32/51), respectively (P < 0.05).
  
  
  CONCLUSIONS
  This new approach produces a better curative effect than the conventional balloon angioplasty with a single D-J stent insertion in treating benign ureteral stricture.
