2. URODYNAMICS

      These studies are utilized for assessment of the lower urinary tracts (bladder, urethra) in chronic retention and incontinance cases. These studies provide information on :

2.1 Cystometery : Volume and pressure change in the bladder.

2.2 Urine flow studies : Volume of urine voided in cc per second of time. A urinary flow rate of 25 ml is considered normal. The other parameters are voiding time, peak flow rate 

2.3 Measuring urine loss in incontinence.

      There are other more complex studies that measure flow with pressure changes. These can be combined with imaging of bladder or Electromyograph of pelvic floor.
