| When the micturation process starts, a volume change is sensed by the microprocessor based device automatically, which determines and stores urinary volume, flow rate and time alongwith other parameters. At the end of micturation process the microprocessor based device programmed to determine parameters relating to urinary flow like voided volume, voiding time, flow time, maximum flow rate, average flow rate and time to maximum flow. It also provides the graphical flow curve of the micturation process by the means of flow rate v/s time. At the end of micturation process, by automatic preset delay, it gives a printout which consists of a graphical flow curve as well as statistics relating to parameters of urinary flow altogether with the patients information.
The urinary system consists of two kidneys, two ureters, bladder and urethra. The kidneys principally function to filter the waste products from the blood and circulate the cleaned blood in the body. The ureters carry the waste products (urine) from the kidneys to the bladder. In the bladder, the urine is stored until urination. Thereafter, the urine passes out of the bladder through urethra.
Prostate is a accessory sex gland found in men at the base of the urinary bladder and surrounds the urethra. As the men age, the prostate gland slowly enlarge (called BPH) and may press on the urethra and cause flow of urine to be slower and less forceful with some other adverse symptoms. BPH is diagnosed with the help of ultra sound examination of urinary system and uroflowmetry.
Uroflowmetry is one way of integrating the activity of the bladder and the outlet during the emptying phase of micturation. The micturation process consists of detrusor function of bladder neck opening and urethral conductivity. It can establish the type of abnormality and filter the patients who require further invasive procedures. Thus, it avoids under treatment in the younger age group & restricts overzealous invasive procedure in the older age group. |
