Uroflowmetry
Abbildung 1: Uroflowmetry obtained from a male patient with urodynamic evidence of detrusor overactivity and symptoms of urgency. Note rapid acceleration of flow at initiation of urination, due to the sudden release of a voluntarily contracted external sphincter while the detrusor is in a state of contraction which could not be inhibited.

Isovolumetric pressure
Abbildung 2: Comparison of maximum isovolumetric pressure (Pisv) measured from continuous occlusion test in men (left bars) and women (right bars). In both men and women, Pisv is significantly higher in patients with urodynamic evidence of detrusor overactivity (grey bars) compared to those with stable bladders (black bars): *p < 0.05.

Cystourethrogram
Abbildung 3a-b: Voiding cystourethrogram from 65 year old patient with longstanding lower urinary tract symptoms and urgency as the most bothersome symptom. This patient was originally treated for OAB but failed anticholinergic treatment and other conservative measures. Videourodynamics showed no evidence of outlet obstruction but did show evidence of severe reflux into the prostatic ducts (arrows) and large pseudodiverticulum at the dome (arrowhead) indicating severe unrecognized morphologic alterations. These changes are attributed to dysfunctional (non-neuropathic) striated sphincter behavior. B) Post void film shows complete emptying of the bladder, but a substantial amount of contrast is retained in the prostatic ducts.
