IPSS = International Prostate Symptom Score. Qmax = maximum urinary flow. Dan-PSS = Danish Prostate Symptom Score. PSA = prostate specific antigen. The IPSS is a validated 7-item questionnaire assessing the frequency of lower urinary tract symptoms (0 = never, 5 = (almost) always); The IPSS ranges from 0–35. The Dan-PSS is a 12 item questionnaire multiplying the presence of symptoms (0–3) with a subjective bother score (0–3); the Dan-PSS ranges from 0–108.
