VALUE OF THE DANISH PROSTATE SYMPTOM SCORE COMPARED TO THE AUA SYMPTOM SCORE AND PRESSURE FLOW STUDIES IN THE PREOPERATIVE EVALUATION OF MEN WITH SYMPTOMATIC BENIGN PROSTATIC HYPERPLASIA/

The Danish Prostate Symptom Score (DAN-PSS) is a new questionnaire for the assessment of lower tract urinary symptoms (LUTS), which claims t o be able to predict bladder outlet obstruction. We evaluated the abil ity of the DAN-PSS to assess LUTS, to predict obstruction, and to pred ict treatment outcome in men with symptomatic uncomplicated BPH. Twent y-five consecutive men with symptomatic uncomplicated BPH filled in th e AUA symptom score and the DAN-PSS and underwent uroflowmetry and pre ssure-flow studies prior to transurethral prostatic resection (TURF). Patients were reevaluated 4 days and 8 months after surgery. AUA score and DAW-PSS both assessed LUTS and were sensitive to symptom changes after therapy. Compared to pressure/flow studies, neither score correl ated with bladder outlet obstruction. Peak urinary flow, however, corr elated significantly with obstruction. None of the diagnostic tools us ed was able to improve patient selection for surgical treatment. The D AN-PSS is a valid and sensitive questionnaire for the assessment of LU TS. It is not able, however, to predict bladder outlet obstruction. In men with uncomplicated BPH, urodynamic evaluation of bladder outlet o bstruction did not improve the subjective outcome of TURF.
