title: [Transurethral resection of bladder neck for female bladder neck sclerosis: a prospective urodynamics study].
abstract: OBJECTIVE
  To explore the probable unsuccessful reasons for transurethral resection of bladder neck (TUR-BN) of female bladder neck sclerosis.
  
  
  METHODS
  Thirty eligible cases received urodynamic inspections at pre-operation, post-operation of months 1, 2, 3 and 6 and year 1.
  
  
  RESULTS
  TUR-BN was effective in 27 patients (90%), but ineffective in 3 (10%). Among the effective cases, the urodynamic parameters of Qmax and Qave increased (P < 0.05) while the residual urine volume and maximum pressure of detrusor contraction decreased (P < 0.05). The above four parameters showed no difference in those ineffective cases (P > 0.05).
  
  
  CONCLUSIONS
  TUR-BN is an effective therapy for female bladder neck sclerosis. Those ineffective cases are probably caused by functional obstruction. Further urodynamic imaging studies may help to confirm the causes.
