Signs and Symptoms
copied from Bacteriuria

The increased risk of asymptomatic or symptomatic bacteriuria in pregnancy is due to physiological changes that occur in a pregnant women and promote unwanted pathogen growth in the urinary tract.

Asymptomatic
Asymptomatic bacteriuria is bacteriuria without accompanying symptoms of a urinary tract infection and is commonly caused by the bacterium Escherichia coli. Other potential pathogens are Klebsiella spp., and group B streptococci. It is more common in women, in the elderly, in residents of long-term care facilities, kidney transplant recipients and in people with diabetes, bladder catheters, and spinal cord injuries. People with a long-term Foley catheter always show bacteriuria. Chronic asymptomatic bacteriuria occurs in as many as 50% of the population in long-term care.

There is an association between asymptomatic bacteriuria in pregnant women with low birth weight, preterm delivery, pyelonephritis, cystitis, infection of the newborn and fetus death. However, most of these studies were graded as poor quality. Bacteriuria in pregnancy also increases the risk of preeclampsia.

Symptomatic
Symptomatic bacteriuria is bacteriuria with the accompanying symptoms of a urinary tract infection (such as frequent urination, painful urination, chills, fever, back pain, abdominal pain and blood in the urine) and includes pyelonephritis or cystitis.

Diagnosis

 * Urine culture is quantitative and very reliable, but the disadvantages are that it can take one or two days for results to be obtained and it is expensive.
