title: [Etiology and treatment of bladder spasm associated with benign prostatic hyperplasia].
abstract: OBJECTIVE
  To investigate the etiology and treatment of bladder spasm associated with benign prostatic hyperplasia (BPH).
  
  
  METHODS
  Urodynamic tests were performed in 102 cases of BPH before operation. The correlation of bladder spasm with aging, international prostate symptom score (IPSS), quality of life, prostatic volume, operation methods and urodynamic indexes was studied by t and chi2 tests.
  
  
  RESULTS
  The incidences of bladder spasm in the lower compliant bladder and unstable bladder were 32.1% (9/28) and 42.5% (13/20), and those after suprapubic prostatectomy and transurethral resection of the prostate (TURP) were 50.9% (26/51) and 23.3% (12/51). There was significant difference between operation methods (P < 0.05).
  
  
  CONCLUSIONS
  Bladder spasm easily develops in the lower compliant bladder and unstable bladder, especially after suprapubic prostatectomy. TURP might decrease the incidence of bladder spasm after BPH operation.
