title: [Clinical application of urodynamic study in patients with neurogenic bladder by pelvic fracture postoperative].
abstract: OBJECTIVE
  To explore the clinical value of urodynamic study in patients with neurogenic bladder by pelvic fracture postoperative.
  
  
  METHODS
  Postoperative 12 cases with pelvic fracture resulted in uroschesis, there were 8 males and 4 females,and age from 26 to 70 years with an average of 46.5 years. Urodynamic study was done in patients at 1 d,1,3 weeks after operation and compared with 12 cases normal subjects.
  
  
  RESULTS
  There was a significant relationship between urodynamic parameter (including residual urine volume of bladder, max free flow, urethral closing pressure in filling end and so on) and course of disease. The residual urine volume of bladder and urethral closing pressure in filling end increased of urodynamic tests in all patients with uroschesis as compared with the normal subjects (P < 0.05); but max free flow decreased at 1 d, 1, 3 weeks after operation (P < 0.05). In the patients with uroschesis, residual urine volume of bladder markedly increased (P < 0.05) and urethral closing pressure in filling end markedly depressed (P < 0.05) at 1 week after operation than other time (at 1 d, 3 weeks after operation), but max free flow had not significant difference (P > 0.05).
  
  
  CONCLUSIONS
  Urodynamic study might evaluate regenerate the degree of neurogenic bladder by pelvic fracture postoperative and predict the prognosis of the neurogenic bladder.
