VCUG VCUG
Voiding cystourethrogram, an imaging study to evaluate bladder function and detect reflux.
detrusor overactivity
Involuntary bladder muscle contractions during bladder filling that may cause urgency and incontinence.
detrusor-external sphincter dyssynergia
Neurological condition where bladder muscle and external sphincter contract simultaneously, preventing normal voiding.
detrusor-sphincter dyssynergia

dysfunctional voiding
Learned voiding pattern characterized by intermittent relaxation of external sphincter during voiding.
ectopic ureter
Congenital anomaly where the ureter inserts outside the normal trigonal area of the bladder.
enterocystoplasty

meatal stenosis
Narrowing of the urethral opening (meatus) causing a thin, deflected urinary stream and potential voiding difficulties.
meatotomy
