title: [Chronic prostatitis symptom index of Chinese].
abstract: OBJECTIVE
  To establish the chronic prostatitis symptom index which more suitable for Chinese to refine and standardize evaluation of current symptoms in men with "chronic prostatitis".
  
  
  METHODS
  The literature of previous work was reviewed to develop a symptom index instrument. There were 18 questions representing three broad categories: pain symptoms, urinary symptoms and other symptoms. To evalute the clinical utility and applicability for Chinese people of this tool, we used it in 100 patients with chronic prostatitis and 100 control patients (40 with benign prostatic hyperplasia, BPH; 30 with infertility; 30 with erectile dysfunction).
  
  
  RESULTS
  Of the three aspects symptoms, the primary component was pain. But pain in lower back and lower abdomen had less specificity. Pain in the rectal area was not very common but it could well distinguish patients with prostatitis from those BPH, infertility and ED. Urinary symptoms were also common. We used 5 symptom questions in urinary aspect in the last version of this index. In other symptoms, we dropped the question of uncomfortable of waist and back at last. It could not distinguish patients with prostatitis from those infertility and erectile dysfunction. Finally we analyzed the result and modified the new version of chronic prostatitis symptom index. It included 5 pain symptom questions, 5 urinary symptom questions and 2 other symptom questions. There are 12 questions in total.
  
  
  CONCLUSIONS
  The chronic prostatitis symptom index we developed was validated and useful in clinical practice as well as research protocols. Moreover, it was more suitable for Chinese people.
