Urodynamic Bladder Measurement
Urodynamic testing measures how the urinary bladder behaves in women who have bladder problems and
urinary incontinence. Urodynamic testing is very useful in helping to determine how well the urinary
bladder stores and empties urine. Dr. Pizarro recommends this measurement for women who suffer from
leakage of urine, frequent urination, having to get up at night to urinate and those with
disorders of pelvic support.
For such patients, the doctor will make sure that there's no bladder infection causing the symptoms. After
that, the urodynamic measurement can be performed in the office in a very short amount of time. Urodynamics
is a painless test that involves placing a small catheter in the urinary bladder and another one for a short
distance into the rectum to measure pressures inside the abdomen and bladder. The bladder is then slowly
filled with sterile water to measure the size, pressure and sensitivity of the bladder.
During this gentle test, patients are asked to cough and strain while very specific measurements are taken
using computerized equipment and fiber-optic technology. At the same time, the patient is evaluated to see
if there is leakage or spasm of the bladder. When the patient's bladder is full with water, she then voids
into a special commode to see how well she is able to empty her bladder.
Computerized graphs which display a great deal of useful information are then generated. Dr. Pizarro
carefully reviews the information to see whether there are any visible causes of the symptoms that the
patient is experiencing. Such causes could be a very overactive bladder, a weakened opening of the
bladder (the urethra), a weak bladder muscle, or blockage of urinary flow.
Although no test is perfect, Dr. Pizarro finds urodynamic measurement very useful in counseling
patients and as a very important part of helping to determine treatments. In particular, when a
patient is considering surgery for repair of urinary leakage or disorders of pelvic support,
urodynamic measurements help get as much information about how the bladder is behaving.
