Bladder outlet obstruction (BOO) with benign prostatic hyperplasia (BPH) was determined by pressure-flow studies. Residual urine volume was measured by urethral catheterization. Fifty-one patients with or without BOO were investigated for residual urine. The mean residual urine volume was 32.8 +/- 35.9 ml and 25.2 +/- 22.7 ml in BOO group (31 patients) and no BOO group (20) respectively. The range of residual urine volume was from 6 to 210 ml and from 3 to 88 ml in the two groups respectively. Residual urine volume was not statistically different 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). Residual urine determination was not a reliable criterion for selection of patients for surgery. The cause of residual urine is not only BOO. The patients with BOO may present insignificant residual urine. It is evident that the absence of post-void residual urine does not rule out BOO.
通过压力流研究确定良性前列腺增生（BPH）所致膀胱出口梗阻（BOO）。通过尿道插管测量残余尿量。对51例有或无BOO的患者进行残余尿调查。BOO组（31例患者）和无BOO组（20例患者）的平均残余尿量分别为32.8±35.9 ml和25.2±22.7 ml。两组的残余尿量范围分别为6至210 ml和3至88 ml。BOO组和无BOO组之间的残余尿量无统计学差异（P>0.05）。BOO组和无BOO组之间的压力流研究结果有显著差异（P<0.01）。残余尿测定不是选择手术患者的可靠标准。残余尿的原因不仅是BOO。有BOO的患者可能残余尿量不明显。显然，排尿后无残余尿并不能排除BOO。
