... accepted that the conventional clinical signs and symptoms do not correlate with obstruction as urodynamically defined. In the present study, objective obstruction and detrusor contractility parameters were calculated from detrusor pressure and flow rate measurements in 22 patients before and after...

... significantly increased the contractile frequency of the renal pelvis. For the bladder 10 ––3 M thiphenamil resulted in a 50% inhibition of the phasic contractions, while 3 × 10 ––4 M oxybutynin and 3 × 10 ––6 M verapamil were needed to achieve the same level of inhibition. Thiphenamil at lower doses (10 ––4 M...

...W.A. van Duyl; B.L.R.A. Coolsaet; R. van Mastrigt In clinical urodynamic investigations there is a need for the assessment of the contractility of the bladder. A method, based on isometric cystometry, is proposed and evaluated in normal subjects. The method, adopted from cardiovascular research...

...R. van Mastrigt; D.J. Griffiths Measurements have been made in vitro of the active mechanical properties of complete pig bladders, electrically stimulated to contract. The results are described with the aid of a model of the bladder wall consisting of a contractile element in series with an elastic...
