为确定前列腺增生 (BPH)时膀胱出口梗阻 (BOO)与剩余尿的关系 ,采用压力 体积流量测定法 ,分析 1 4 5例有或无膀胱出口梗阻的前列腺增生患者的剩余尿情况。BOO组 87例 ,无BOO组 58例 ,剩余尿分别为 ( 35.2± 37.1 )mL和 ( 2 8.2± 2 0 .7)mL ,2组间无显著差异 (P >0 .0 5) ;但最大尿体积流量、最大尿体积流量时的逼尿肌压均存在显著差异 (P <0 .0 1 )。提示膀胱出口梗阻与剩余尿并非简单的因果关系。
To determine the relationship between bladder outlet obstruction (BOO) and residual urine in patients with benign prostatic hyperplasia (BPH), the residual urine of 145 patients with benign prostatic hyperplasia with or without bladder outlet obstruction was analyzed by pressure-volume flow assay. There were 87 cases in BOO group, 58 cases in no BOO group and 35.2 ± 37.1% in residual urine and 2 8.2 ± 20.7 in mL group, respectively, with no significant difference between the two groups (P> 0.05) Urine volume flow, maximum urinary volume flow detrusor pressure were significantly different (P <0. Tip bladder outlet obstruction and residual urine is not a simple causal relationship.
