Abstract: Objective To investigate the significance of Qmax and residual urine in evaluation of bladder function in the patients with benign prostatic hyperplasia (BPH).Methods The clinical data of 61 patients with BPH and 20 healthy persons in control group were evaluated.Bladder function,uroflowmetry and ultrasonic residual urine measurement were performed in the 2 groups.The correlation between Q max and residual urine in BPH group was investigated.Results There was significant difference in Qmax between the BPH group and control group (8 vs.21 ml/s,u=-6.090,P=0.007).There was significant difference in residual urine between the 2 groups (60 vs.9 ml,u =-6.718,P=0.005).And there was a negtive correlation between residual urine and Qmax in BPH group (r=-0.366,P=0.009).Conclusion It is useful to measure the Qmax and residual urine in evaluation of bladder function affected by bladder outlet obstruction caused by BPH.
