Detrusor contractility was evaluated by measuring the increase in isometric pressure during a stop test in 25 men with benign prostatic hyperplasia. Before transurethral prostatic resection (TUR), a low pressure increase (delta P det iso) was associated with a large volume of residual urine. After TUR both the speed and the amplitude of isometric detrusor contractions during the stop test increased. A pre-operative low detrusor pressure increase was correlated with a great improvement in flow rate after TUR. The value of the stop-flow test was limited, however, since improvement in other urodynamic parameters could not be predicted.
通过在25名良性前列腺增生男性患者的憋尿试验中测量等长压力的增加来评估逼尿肌收缩力。经尿道前列腺切除术（TUR）前，低压力增加（ΔPdetiso）与大量残余尿量相关。TUR后，憋尿试验期间等长逼尿肌收缩的速度和幅度均增加。术前逼尿肌压力增加较低与TUR后流速的显著改善相关。然而，憋尿试验的价值有限，因为无法预测其他尿动力学参数的改善情况。
