title: [Value of preoperative urodynamics to the prognosis of transurethral prostate resection for benign prostatic hyperplasia].
abstract: OBJECTIVE
  To establish the value of preoperative urodynamics to the outcome prediction of transurethral prostate resection (TURP) for benign prostatic hyperplasia (BPH).
  
  
  METHODS
  One hundred and sixty patients with BPH underwent urodynamic tests. Preoperative IPSS (International Prostate Symptom Score) and QOL (Quality of Life) were compared with those 8 to approximately 11 months after operation.
  
  
  RESULTS
  The parameters of urodynamic tests (max. free flow, detrusor pressure at max. flow, Schafer grade, Abrams-Griffiths No, urethral resistance factor, cystometric capacity, effective capacity). IPSS and QOL were improved after operation (P < 0.001). And all the relative coefficients of linear dependence analysis, IPSS, QOL and max. free flow, detrusor pressure at max. flow, Schafer grade, Abrams-Griffiths value, urethral resistance factor, cystometric capacity, and effective capacity conducted postoperatively, were statistically significant.
  
  
  CONCLUSIONS
  Preoperative urodynamics of transurethral prostate resection for benign prostatic hyperplasia may provide indication for operation and predict postoperative improvement of symptoms. Preoperative urodynamics should be considered as a routine examination.
