The Urinary Tract
The kidneys, uterus, urinary bladder and the urethra constitute this tract. Each of the two kidneys in the body possesses over 20 million functional units called nephrons which filter the blood removing from it about 22 liters of fluid urine for final excretion. The urethra connect the kidneys to the bladder, which stores urine until excretion takes place through the urethra.Urinary Symptoms
Infection, inflammation and obstruction produce symptoms associated with urination.- Frequency, urgency and urination at night are common symptoms of a urinary tract infection.
- Dysuria – painful urination and burning pain in the urethra on urination are associated with bladder and prostate gland problems.
- Enuresis (bed wetting) may be due to urinary tract infection or psychological reasons.
- Urinary incontinence – It may be due to structural defects in the kidneys, urinary tract or physical stress, the urgency associated with infection or dribbling of urine associated with over distended bladder.
