Fig. 17.1 Normal voiding pattern Notice in Fig. 17.1, as bladder filling occurs EMG activity increases (increased somatic innervation to external sphincter) at the line annotated as “strong desire.” Once…

where V t = volume of noncontracting bladder wall tissue [7]. Although some studies report WF and WFmax, no consensus has been made regarding normative values particularly in female patients [6, 8,…

Fig. 14.1 (a) This is an example of detrusor overactivity (highlighted by the circle) during the filling cystometrogram. The P det tracing is calculated using P ves and P abd…

Fig. 1.1 Three examples of uroflow patterns: (a) Normal bell-shaped. (b) Obstructive pattern. (c) Straining pattern It is helpful to obtain a PVR after completion of uroflowmetry in order to…

Fig. 6.1 Top: Water charged catheter with appropriate orientation of catheter. Lumen transmits pressure to the transducer. Middle: Occlusion of the catheter lumen by urothelium precludes pressure transmission. Bottom: Air-charged…
