Definition

Urinary incontinence, also known as wetting oneself, is a condition characterized by unintentional leakage of urine. The process of normal delivery or vaginal birth can increase the risk of urinary incontinence in some individuals. This can be considered a common side effect that may improve over time as the body adapts, and urinary incontinence may resolve on its own.

According to a 2019 study, it is estimated that one in three mothers experience urinary incontinence during the second trimester of pregnancy to the first three months after childbirth. Urinary incontinence is more common in women than in men. This is believed to be caused by hormonal changes that often occur during pregnancy, childbirth, and menopause, leading to urinary incontinence.

The pelvic floor muscles play a crucial role in supporting the bladder. During pregnancy and after childbirth, hormonal and anatomical changes occur, resulting in a decrease in the strength of the pelvic floor muscles. Some individuals may experience damage to these muscles during childbirth. Additionally, the nerves controlling the bladder can be damaged, especially during vaginal delivery.

Postpartum urinary incontinence occurs when someone cannot control their bladder. While it may start during pregnancy, it can persist or worsen after childbirth.

There are two main types of urinary incontinence: stress incontinence and urge incontinence. Stress incontinence occurs when there is pressure on the bladder, such as during sneezing, coughing, or laughing, leading to leakage. Urge incontinence, on the other hand, happens when someone has a strong urge to urinate but leaks before reaching the bathroom.

Causes

During pregnancy, hormonal changes occur that lead to the relaxation of muscles and tissues supporting the bladder, intestines, and uterus. These muscles, collectively known as the pelvic floor muscles, play a crucial role in maintaining bladder control. When the baby descends through the birth canal (vagina) during delivery, the pelvic floor muscles stretch to accommodate the passage of the baby and may remain stretched for some time afterward. This stretching, combined with hormonal factors, can weaken the muscles responsible for controlling the bladder, leading to urinary leakage or postpartum urinary incontinence.

Risk factor

According to the Australian Government Department of Health and Aged Care, mothers are more likely to experience postpartum incontinence if they have:

• Pre-existing incontinence before childbirth
• Bladder problems during pregnancy
• Prolonged labor
• First-time childbirth
• Delivering a large baby
• Difficulties during childbirth, such as requiring stitches or experiencing specific tears in the vaginal area

Additionally, a study conducted in 2021 identified normal vaginal delivery, or vaginal birth, as a significant risk factor for stress urinary incontinence. In contrast, individuals who undergo a cesarean section (C-section) may have a lower risk of stress incontinence compared to vaginal delivery.

Symptoms

Patients with urinary incontinence may experience involuntary leakage of urine, which can be accompanied by other symptoms such as muscle spasms or tension in the pelvic area, urinating during the night, and visiting the bathroom more than 8 times a day or more than 2 times each night. Urinary leakage due to stress incontinence can occur during specific activities such as exercise, laughing, coughing, sneezing, or lifting heavy objects. On the other hand, symptoms of urgency incontinence may include sudden and uncontrollable urination.

Diagnosis

The diagnosis of postpartum incontinence is established through medical interviews, physical examinations, and, if available and necessary, further diagnostic tests. During the medical interview, the doctor will inquire about symptoms. If the symptoms suggest postpartum incontinence, the doctor will proceed with a physical examination and, if necessary, diagnostic tests.

In physical examinations, the doctor will search for clinical signs suggestive of postpartum urinary incontinence. In cases of postpartum urinary incontinence, doctors may find muscle spasms or tension in the pelvic area and a history of vaginal delivery.

Diagnostic tests play a crucial role in diagnosing postpartum incontinence. Tests such as urinalysis can help rule out the possibility of infection as another potential cause of the mother's urinary incontinence.

Management

Individuals experiencing postpartum urinary incontinence can explore lifestyle adjustments and medication options to manage the condition. Some effective strategies include using absorbent pads, such as pads or diapers, which can be worn inside underwear to contain sudden urine leaks and absorb them directly. Additionally, pelvic floor muscle exercises, like Kegel exercises, can help strengthen the muscles. Another option is pessary rings, devices inserted into the vagina to support the urethra and prevent leakage.

There are also several medications available to alleviate postpartum urinary incontinence. However, these medications should be prescribed directly by a healthcare provider who can monitor the patient's clinical progress and development.

Complications

While complications are generally rare, urinary incontinence specifically can lead to embarrassment and a decreased quality of life. This, in turn, may result in anxiety and depression as psychological complications of postpartum urinary incontinence. Additionally, skin problems such as red spots or infections can occur in moist areas, and urinary tract infections may also develop if incontinence persists.

Prevention

Until now, there hasn't been any significant prevention method for avoiding cases of postpartum urinary incontinence. However, several measures can reduce the risk, including maintaining a balanced diet, abstaining from smoking and alcohol, regular exercise, and ensuring adequate rest. Specifically, Kegel exercises can help strengthen pelvic floor muscles after childbirth, potentially reducing the duration of postpartum urinary incontinence.

When to see a doctor?

If you experience worsening symptoms such as bladder issues persisting for 6 weeks postpartum (including more frequent urinary leakage), it's advisable to seek further evaluation from a specialist. This could include an internist, urologist, or obstetrician-gynecologist specializing in urogynecology. The doctor will conduct a medical interview, physical examination, and specific diagnostic tests to establish a precise diagnosis of the underlying condition and determine the appropriate management tailored to your needs.
