Leukocytes in Urine During Pregnancy: Symptoms and Treatment


Pregnancy is a beautiful journey marked by various physiological changes which supports the growth and development of the baby. During this remarkable process, certain health concerns may arise, one of which is the detection of leukocytes in urine. Leukocytes, commonly known as white blood cells, are  defenders of body against infections. However, their presence in urine during pregnancy should be detected and treated. In this article we will discuss about the causes, symptoms, and treatment options related to leukocytes in urine during pregnancy.

Understanding Leukocytes

Leukocytes are vital components of the immune system, which identifies and treat foreign bodies such as bacteria, viruses, and fungi. These specialized cells protects the blood and tissues, easily responding to signs of infection or inflammation. The presence of leukocytes in Urine  indicates an immune response within the urinary tract, that serves as a crucial diagnostic marker for various conditions.

Causes of Leukocytes in Urine During Pregnancy

Urinary Tract Infections (UTIs): Most common causes of leukocytes in urine during pregnancy is Urinary tract infections(UTIs). Hormonal changes and the physical alterations occurring in the urinary tract during pregnancy make pregnant women more susceptible to UTIs. Bacteria entering the urethra and proliferating within the urinary system typically cause these infections.  UTIs can progress and lead to complications such as kidney infections and preterm labor, risks to maternal and fetal health if left untreated.


Asymptomatic Bacteriuria:

Asymptomatic bacteriuria is characterized by the presence of bacteria in the urine without any symptoms of infection. Factors such as hormonal fluctuations and urinary stasis make pregnant female more prone to this condition. If left untreated asymptomatic bacteriuria increases the risk of developing symptomatic UTIs. Routine urine screening and interventions during prenatal care,  reducing the likelihood of complications.

Kidney Infections (Pyelonephritis):

In severe cases, leukocytes in urine during pregnancy may indicate a kidney infection, medically termed pyelonephritis. When bacteria ascend from the lower urinary tract to the kidneys, leading to inflammation and infection this is known as pyelonephritis. Symptoms of this condition such as fever, flank pain, nausea, and vomiting, requires prompt medical attention to prevent systemic complications and adverse pregnancy outcomes.

Symptoms of Leukocytes in Urine During Pregnancy

Increased Urination: 

Due to hormonal changes and the expanding uterus exerting pressure on the bladder, pregnant female experience increased urinary frequency. However, if accompanied by symptoms such as pain or burning sensation during urination, it may be  urinary tract infection which requires early evaluation and treatment.

Pain or Discomfort:

Pain or discomfort during micturition can indicate an underlying urinary tract infection or kidney infection. The sensation of burning, stinging, or pressure during urination needs  assessment by a healthcare provider to determine the cause and implement appropriate management strategies.

Changes in Urine Appearance or Odor:

Alterations in the appearance or odor of urine, such as cloudiness, foul smell, or presence of blood, may indicate the presence of bacteria or white blood cells. These changes requires further investigation to identify underlying infections or inflammatory processes affecting the urinary tract.

Treatment of Leukocytes in Urine During Pregnancy:

Antibiotic Therapy:

Antibiotics are the mainstay  of treatment for urinary tract infections and asymptomatic bacteriuria during pregnancy. However, selective  antibiotics are  safe for both maternal and fetal health. During visit doctor prescribe antibiotics based on urine culture results, aiming to eradicate the causative bacteria and prevent recurrence of infections.



Adequate hydration plays a crucial role in supporting urinary tract health during pregnancy. Drinking plenty of water helps to flush out bacteria from the urinary system, reducing the risk of recurrence of urinary tract infections. Pregnant women should strive to maintain optimal hydration levels by consuming sufficient fluids throughout the day.

Prenatal Care:

Regular antenatal check-ups are essential for monitoring maternal and fetal well-being throughout pregnancy. Urine analysis performed during antenatal visits enables early detection of abnormalities such as leukocytes and bacteria. Early identification and management of urinary tract infections helps to minimize complications and ensuring favorable pregnancy outcomes.


Leukocytes in urine during pregnancy serve as important indicators of underlying urinary tract issues, including infections and inflammatory conditions. By early detection of causes, symptoms, and treatment options associated with leukocytes in urine,  mothers can actively take care of  their urinary tract health and can promote a smooth journey. Through collaborative efforts between healthcare workers and pregnant females, early intervention and comprehensive management strategies can decrease the risk and improves maternal and fetal outcomes.
