The tests are most often arranged for men with enlarged prostate glands, and for women with incontinence that has either failed conservative treatment or requires surgery. Probably the most important group in whom these tests are performed are those with a neuropathy such as spinal injury. In some of

Uroflowmetry: Free uroflowmetry measures how fast the patient can empty his/her bladder. Pressure uroflowmetry again measures the rate of voiding, but with simultaneous assessment of bladder and rectal pressures. It helps demonstrate the reasons for difficulty in voiding, for example bladder muscle

These tests may be as simple as urinating behind a curtain while a doctor listens, but are usually more extensive in western medicine. A typical urodynamic test takes about 30 minutes to perform. It involves the use of a small catheter used to fill the bladder and record measurements. What is done
205:: measures the pressure in the rectum and in the bladder, using two pressure catheters, to deduce the presence of contractions of the bladder wall, during bladder filling, or during other provocative maneuvers. The strength of the urethra can also be tested during this phase, using a cough or

Post-void residual volume: Most tests begin with the insertion of a urinary catheter/transducer following complete bladder emptying by the patient. The urine volume is measured (this shows how efficiently the bladder empties). High volumes (180 ml) may be associated with

For example, a patient complaining of urinary urgency (or rushing to the toilet), with increased frequency of urination can have overactive bladder syndrome. The cause of this might be detrusor overactivity, in which the bladder muscle (the
