Methods Urodynamic study was carried out in 103 BPH patients who were assigned to group A(no residual urine), group B( residual urine【 60 ml) and group C( residual urine 60 - 100 ml). Results Qmax, URA, DR and DI were not significantly different between group C and group B (P 】 0.05) but significantly different between group C and A or between B and A(P【0.05). Conclusion The conventional conception that surgical intervention is indicated when the residual urine being 】 60 ml should be strictly followed. Early surgical intervention should be undertaken if the bladder outlet obstruction or bladder function deteriorated by BPH causing residual urine. Other causes such as neurogenic should be ruled out before surgery. 10 refs,2 tabs.展开更多
