title: [Roles of BPH impact index in the evaluation of impaired urination in patients with BPH].
abstract: OBJECTIVE
  To assess the significance and current status of the benign prostatic hyperplasia (BPH) impact index (BII) in the evaluation of subjective symptoms of impaired urination in so-called QOL disease, BPH.
  
  
  METHODS
  Over the past 2 year-period, in 159 patients with the diagnosis of BPH were asked to reply to each of the international prostate symptom score (I-PSS), QOL index and BII questionnaires. The subjective symptom scores (a total of 246 points) were evaluated from the viewpoint of clinical statistics in the search for any these and to find which questions cover the BII, most.
  
  
  RESULTS
  1) Statistically significant but moderate correlations were observed among I-PSS total score, QOL index and BII. The correlations among Qmax, BII and QOL were very weak. 2) Out of the 11 domains in both IPSS and BII, 2 questions of BII ("bothersomeness caused by urinary problems" and "degree of worry about well-being") and 4 questions of IPSS ("residual sense," " pollakisuria," "weak urinary stream" and "nocturia") were shared as QOL indices. Patient satisfaction was affected also by the questions in the BII. 3) Of the 7 BPH symptoms assessed in IPSS, 4 symptoms ("residual sense," "pollakisuria," "weak urinary stream" and "nocturia") affected the QOL index, and 4 symptoms ("urgency on micturition," "residual sense," "nocturia" and "strain at urination") affected BII. 4) Of the 7 symptoms assessed by IPSS, different symptoms affected each of the 4 BII questions.
  
  
  CONCLUSIONS
  It is needed to assess BPH symptoms not only by the IPSS and QOL index but also based on BII to provide the detailed therapeutic instructions and thorough patients consultation.
