Stress Urinary Incontinence: Causes, Symptoms, and Treatment Options

 By: DelCharco M.D. OB/GYN

At a Glance

  • Stress urinary incontinence (SUI) affects more than 1 in 3 women at some point in their lifetime.
  • It occurs when pressure on the bladder causes urine to leak during activities like laughing, sneezing, coughing, or exercising.
  • Causes include pregnancy, childbirth, menopause, pelvic floor weakness, and aging.
  • Effective treatments range from pelvic floor therapy to minimally invasive procedures.
  • At DelCharco, M.D. OB/GYN, we offer evidence-based diagnosis and treatment to help women regain bladder control and quality of life.

Quick Summary

Condition: Stress urinary incontinence (SUI)
 Symptoms: Urine leakage during physical activity, coughing, laughing, sneezing, or lifting
 Diagnosis: Pelvic exam, bladder testing, medical history review, and sometimes imaging
 Treatment: Pelvic floor therapy, lifestyle changes, pessaries, medications, urethral support procedures, and surgical options such as mid-urethral sling

What Is Stress Urinary Incontinence?

Stress urinary incontinence happens when weak pelvic floor muscles or urethral support allow urine to leak when pressure is placed on the bladder. Unlike urge incontinence, which is caused by overactive bladder signals, SUI is a mechanical issue related to support structures.

According to the Mayo Clinic, SUI occurs when pelvic tissues and muscles are too weak to keep the urethra closed during pressure increases.

Women commonly experience leakage during activities such as:

  • Sneezing
  • Laughing
  • Jumping
  • Running
  • Lifting heavy objects
  • Standing up quickly
  • Sexual activity

Many women feel embarrassed discussing these symptoms, but SUI is extremely common and very treatable.

Common Causes of Stress Urinary Incontinence

Several biological and lifestyle factors contribute to weakening of the pelvic floor and urethral support.

1. Pregnancy and Vaginal Childbirth

Childbirth is one of the strongest risk factors for SUI. Vaginal delivery can stretch and weaken the pelvic muscles and connective tissues.

2. Menopause and Hormonal Shifts

A decline in estrogen affects the tissues of the vagina and urethra, reducing elasticity and muscle tone.

3. Pelvic Floor Weakness

Inactivity, chronic straining, and general aging all contribute to reduced pelvic muscle strength.

4. Obesity

Increased intra-abdominal pressure due to abdominal obesity places additional stress on the pelvic floor and contributes to urinary incontinence.

5. Prior Pelvic Surgery

Hysterectomy or pelvic organ prolapse repair can alter support around the urethra.

6. Genetics

Connective tissue strength varies among individuals, which may influence risk.

7. Chronic Cough or High-Impact Activity

Asthma, smoking, or high-impact exercise can put repeated pressure on the pelvic floor.

Understanding the underlying cause helps guide the most effective treatment approach.

How We Diagnose Stress Urinary Incontinence

At DelCharco, M.D. OB/GYN, diagnosis begins with a detailed review of symptoms and medical history, followed by a focused exam. Diagnostic steps may include:

Pelvic Examination

Evaluates pelvic floor muscle strength, organ support, and vaginal health.

Bladder Function Tests

When needed, we may perform:

  • Cough stress test
  • Urodynamic evaluation
  • Post-void residual measurement

These tests help confirm the diagnosis and rule out other conditions.

Ultrasound or Imaging

Used when prolapse or structural changes are suspected. Accurate diagnosis ensures treatment is tailored to your needs and goals.

Effective Treatment Options for Stress Urinary Incontinence

SUI is highly treatable. At DelCharco, M.D. OB/GYN, we offer a full spectrum of treatments depending on severity, lifestyle, and patient preference.

1. Pelvic Floor Physical Therapy

Research shows that pelvic floor muscle training is recommended as a first-line treatment for the most common forms of urinary incontinence, including stress urinary incontinence. 

Therapy involves learning how to:

  • Strengthen pelvic floor muscles
  • Improve muscle coordination
  • Retrain bladder and urethral support

This therapy is often highly effective, especially for mild to moderate SUI.

2. Kegel Exercises

These exercises help strengthen the muscles that support the bladder and urethra. Many women perform them incorrectly, which is why professional guidance is valuable.

3. Lifestyle Modifications

Simple changes can significantly reduce symptoms:

  • Weight management
  • Treating chronic cough
  • Avoiding bladder irritants such as caffeine, alcohol, and carbonation
  • Quitting smoking
  • Managing constipation

4. Pessaries

A pessary is a small device placed in the vagina to support the urethra and bladder neck.

It is a great option for women seeking non-surgical management.

5. Medications

Although there are no FDA-approved medications specifically for SUI, certain treatments may help depending on the cause, such as topical estrogen therapy for menopausal atrophy.

6. Urethral Bulking Injections

Minimally invasive injections add support to the urethral walls, helping reduce leakage.

7. Mid-Urethral Sling Procedure

A mid-urethral sling is one of the most effective and widely used surgical treatments for SUI.
 According to the American Urological Association, slings provide long-term relief for most women.  

This minimally invasive procedure places a small mesh or tissue sling under the urethra to provide support during activities that increase pressure.

Women often experience dramatic improvement in quality of life after this procedure.

Living with Stress Urinary Incontinence

Without treatment, stress incontinence often gets worse over time. It can impact:

  • Exercise and physical activity
  • Intimate relationships
  • Social confidence
  • Clothing choices
  • Mental health and self-esteem

Many women reduce physical activity or avoid social events because of the fear of leakage. You do not need to accept these limitations. Effective treatments exist, and most women experience significant improvement when they seek care.

When to See a Doctor

Schedule an appointment if you experience:

  • Urine leakage during daily activities
  • Difficulty exercising without leakage
  • Increasing frequency or severity of symptoms
  • Pelvic pressure or signs of prolapse
  • Postpartum bladder control changes that are persistent
  • Menopausal bladder changes affecting quality of life

Early care leads to better outcomes and more treatment options.

Stress urinary incontinence is common, but it is not something you need to live with. The condition is highly treatable with the right combination of pelvic support, lifestyle changes, or minimally invasive procedures.
