a special investigative procedure for assessing bladder function. Radio-opaqued dye is introduced into the bladder via a catheter which also contains pressure sensors, allowing doctors to observe the bladder working, to measure the efficiency of bladder emptying, voiding pressures and to assess potential for renal (kidney) problems.
( ouron = urine, and dymamis = power) Is a complex investigation of the urine storage and urine elimination mechanisms. It is indicated when simpler tests cannot explain the cause of urinary incontinence. It is almost always indicated if surgery for urinary incontinence or prolapse is considered. It might be helpful in clarifying the origin of chronic pain, inability to empty the bladder, abnormalities of the urinary stream. The test measures the pressures inside and around the bladder while it is being filled with fluid and during urination. It is not painful but it requires between 15 and 30 minutes to perform.
Urodynamics is the investigation of functional disorders of the lower urinary tract, i.e. the bladder and the urethra. Symptoms are particularly unreliable in the study of the lower urinary tract, so the purpose of urodynamics is to confirm objectively the pathology that a person's symptoms would suggest.
