Fig. 20.1 This study demonstrates: 1. Detrusor overactivity   2. Stress urinary incontinence   3. Impaired compliance   4. Detrusor sphincter dyssynergia (DSD)   5. Increased bladder sensation   Answer…

Fig. 19.1 (a) CMG and PFS, (b) expanded PFS segment, (c) pressure flow nomogram, (d) post-PFS non-invasive uroflow Expanded PFS Segment (Fig. 19.1b). This segment of the tracing begins at…

From the frequency–volume chart maximum and average-voided volumes can be determined as can the median functional bladder capacity which is defined as the median maximum voided volume during every day…

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…
