Video urodynamic parameters in men with underactive bladder.
Fig 1.
The videourodynamic characteristics of patients with underactive bladder.
(A) Detrusor acontractile, reduced bladder sensation, no detrusor contractility (arrow head), and a tight bladder neck (arrows). (B) Low detrusor contractility, low detrusor pressure (arrow heads) and low Qmax, open bladder outlet during voiding (arrows). (C) Low detrusor contractility and early termination, patient used abdominal pressure to empty the bladder (arrow head), the bladder outlet is open (arrows). (D) Detrusor overactivity and impaired contractility, patient had a hypertonic bladder at capacity (arrow head) but the voiding pressure and Qmax are low, the bladder outlet is open (arrows). (E) Slowly increased detrusor pressure (arrow head) and poor relaxing urethral sphincter (arrows). (F) Normal voiding pressure and low Qmax (arrow head), with a narrow bladder neck during voiding (arrows).
