The association between the preoperative International Prostate Symptom Score (IPSS) and QOL score with objective variables including the residual volumes, prostate size and urodynamic parameters was statistically analyzed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Maximum flow rate (Q<jats:sub>max<\/jats:sub>) positively and a residual urine volume (PVR) negatively correlated with symptoms and QOL score. Detrusor overactivity (DO) also was weakly, but broadly associated with the symptoms. Degree of detrusor contractility and bladder capacity had a weak association with only some storage symptoms. The degree of bladder outlet obstruction (BOO) positively related to the scores on urgency, straining and total IPSS. Patients' age had positive correlation with the score on nocturia. The prostate volume was only negligibly correlated with either any symptoms or the QOL score.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Parameters, such as Q<jats:sub>max<\/jats:sub> or PVR, obtained from the noninvasive urodynamics were most widely correlated with symptoms and QOL. Despite a large group with strict selection of men with LUTS possibly relating to BPO being studied, only weak association between the symptoms or QOL and objective parameters including urodynamics was confirmed.
