title: [Endourethral surgery for 46 cases of the complicated urethra stenosis and urethratresia].
abstract: OBJECTIVE
  To evaluate the endourethral surgery for the complicated urethra stenosis and urethratresia.
  
  
  METHODS
  The endourethral surgery, such as internal urethrotomy transurethral scar electrosectomy or transurethral scar plasmakinetic bipolar electrocautery (PKR) or transurethral laser cicatrectomy, were carried out in 46 cases suffering from the complicated urethra stenosis and urethratresia.
  
  
  RESULTS
  The curative rate in this series being achieved by once and twice or three times'operation were 80.43% (39/46) and 13.04% (6/46) respectively. Three cases of treatment failure were caused by long-segment stricture and urethratresia or severe malposition of the urethral proximal and distal to a narrow-caliber area or post-operation infection. Thirty-nine cases have been followed up for 6 to 84 months. Satisfactory voiding has been achieved in all patients.
  
  
  CONCLUSIONS
  Endoscopic surgery was believed to be a safe and efficient therapeutic choice for the complicated urethra stenosis and urethratresia. The success of the treatment depends on understanding the length of the stricture before operation, resecting completely the scar tissue with electric or PKR or laser technique during the process, preventing infection and managing appropriately the urethral catheterization after operation.
