diagnosis of urine storage and voiding disfunction. The Urology Urodynamic Study includes a
FreeFlow test and a Pressure Flow test. A Pressure Flow test involves filling the bladder and
determining the Detrusor pressure Pdet = Pves – Pabd (the difference between the pressure
inside the bladder (Pves) and the pressure inside the abdomen (Pabd)).
