urodynamics

the recording of pressures within the bladder by the use of special equipment that can also record urethral sphincter pressures. Simultaneously, abdominal pressure is usually recorded with a catheter in the rectum, vagina, or ileal conduit. It is an essential investigation in the study of urinary incontinence. In some men, urodynamic studies are necessary to determine if their LOWER URINARY TRACT SYMPTOMS are caused by bladder outflow obstruction or DETRUSOR instability.
