Summary— 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 (ΔP 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.
