前列腺增生症患者膀胱出口梗阻与剩余尿的关系

Clinical Significance of Residual Urine Volume in Bladder Outlet Obstruction with Benign Prostatic Hyper plasia

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。

Bladder outlet obstruction (BOO) with benign prostatic hyperplasia (BPH) was determined by pressure flow studies. Residual urine volume was measured by urethral catheterization. 145 patients with or without BOO were investigated for residual urine. The mean residual urine volume was (35.2±37.1) mL and (28.2±20.7) mL in BOO group (87 patients) and no BOO group (58 patients), respectively. Residual urine volume was not statistically differenct between the BOO group and no BOO group ( P >0.05). The results of pressure flow studies were significantly different between the BOO group and no BOO group ( P <0.01). It is evident that the absence of post void residual urne does not rule out BOO.
