Abstract: 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.

Key words: benign prostatic hyperplasia, bladder outlet obstruction, urodynamics
