Introduction
Millions of people struggle with urinary incontinence worldwide. When other treatments don’t work, severe cases often need surgery. The artificial urinary sphincter (AUS) offers one of the best long-term solutions available today.
This medical device has changed countless lives. It restores urinary control and greatly improves quality of life. Understanding how it works can help you make informed decisions about your care.
What Is an Artificial Urinary Sphincter?
An artificial urinary sphincter is a device surgically placed inside your body. It treats severe urinary incontinence by controlling urine flow. The device copies what your natural urinary sphincter does by squeezing the urethra to stop leaks.
Dr. Sarah Martinez works at Johns Hopkins Medical Center. She explains that “the artificial urinary sphincter works as a replacement for your body’s natural system when that system is damaged beyond repair.”
How the Device Works
The device has three main parts that work together:
- Inflatable cuff: Goes around the urethra and controls urine flow
- Pressure balloon: Keeps steady pressure in the system
- Control pump: Lets you operate the device manually
When turned on, the cuff inflates to squeeze the urethra. This stops urine flow. When you need to urinate, you squeeze the control pump. This deflates the cuff temporarily and lets you urinate normally.
A Brief History
Dr. F. Brantley Scott and his team first developed the device in the 1970s. The early model went through many changes before becoming today’s better devices.
Dr. Michael Thompson teaches at UC San Francisco. He notes that “the modern AUS represents decades of improvements. Current devices last much longer and satisfy patients much better than early models.”
The most common device today is the AMS 800 made by Boston Scientific. Doctors have used this system since 1987. Over 150,000 units have been placed worldwide.
Types of Artificial Urinary Sphincters
Basic Types
Single vs. Double Cuff:
- Single-cuff devices work for most patients
- Double-cuff systems help in complex cases
- Your doctor chooses based on your anatomy
Pressure Settings:
- Low pressure (51-60 cmH2O) for delicate tissue
- Standard pressure (61-70 cmH2O) for typical cases
- High pressure (71-80 cmH2O) for maximum control
Modern Improvements
Today’s devices are much better than older versions:
- They last 10-15 years typically
- They cause fewer tissue problems
- They work more consistently over time
- Surgery is less invasive
How the Device Actually Works
The system uses water pressure principles. Dr. Jennifer Adams works at Mayo Clinic. She describes it: “The system balances providing enough pressure to prevent leaks while allowing normal urination when needed.”
Step-by-Step Process
- At rest: The cuff stays inflated around your urethra, stopping urine flow
- When activated: You squeeze the pump 7-10 times to deflate the cuff
- During urination: The cuff stays deflated for 2-3 minutes
- Auto reset: The system inflates again automatically
Pressure Control
The pressure balloon keeps steady pressure throughout the system. This part is crucial for the device to work well and last long. It prevents pressure changes that could damage the device.
Who Can Get This Device?
Main Reasons for Surgery
Doctors typically recommend artificial urinary sphincters for:
- Stress incontinence after prostate surgery
- Nerve damage from spinal cord injury
- Birth defects affecting sphincter control in children
- Failed previous incontinence surgeries
Dr. Robert Chen directs the program at Cleveland Clinic. He stresses that “choosing the right patient is critical for success. We look at incontinence severity, hand coordination, mental function, and ability to manage the device long-term.”
Who Makes a Good Candidate
Good candidates typically have:
- Severe incontinence that doesn’t respond to other treatments
- Good hand coordination to work the pump
- Realistic expectations about results
- Willingness to follow up with doctors long-term
- No active bladder infection or cancer
Special Groups
Children: Kids with conditions like spina bifida may benefit. However, timing and sizing need special expertise.
Older Adults: Age alone doesn’t disqualify you. But doctors must check mental function and hand coordination carefully.
Previous Surgery Patients: People with failed incontinence procedures may still qualify. Success rates may vary though.
Benefits and Advantages
The artificial urinary sphincter offers major advantages for the right patients.
Main Benefits
- High success rates: 80-90% of patients see significant improvement
- Long-lasting results: Modern devices work well for 10-15 years
- Adjustable pressure: Can be customized for individual needs
- Preserves anatomy: Doesn’t change urethral structure permanently
- Reversible: Can be turned off or removed if needed
Life Quality Improvements
Studies show AUS placement leads to big improvements in:
- Social life: Less worry about accidents
- Physical activity: Can exercise and play sports again
- Relationships: Less impact on intimate life
- Work life: More confidence at work
- Sleep: Fewer nighttime accidents
Dr. Lisa Park specializes in female incontinence. She notes that “the mental benefits often exceed the physical improvements. Patients regain control over their bodies and lives.”
Risks and Limitations
While artificial urinary sphincters are generally safe, you need to understand potential problems.
Surgery Risks
Immediate problems may include:
- Bleeding or blood clots
- Infection at surgery site
- Anesthesia problems
- Temporary inability to urinate
Long-term problems can involve:
- Device breakdown or failure
- Tissue erosion (1-5% of cases)
- Infection requiring device removal
- Incontinence returning
Device Limitations
Important limitations to know:
- Manual operation needed: You must activate the device each time
- Can malfunction: Mechanical devices can fail over time
- MRI restrictions: Some imaging studies may be limited
- Future surgery: Most devices need replacement after 10-15 years
Dr. Mark Rodriguez leads urology at Texas Medical Center. He tells patients that “while problems are uncommon, they can be serious when they happen. That’s why careful patient selection and experienced surgical teams are essential.”
The Surgery and Recovery
Getting Ready for Surgery
Preparation involves several important steps:
- Complete evaluation: Including bladder tests and scope exam
- Health optimization: Treating any other health problems
- Patient education: Detailed discussion of how device works
- Infection prevention: Antibiotics before surgery
The Operation
The surgery typically takes 1-2 hours under general anesthesia. The standard approach involves:
- Perineal cut: Gives best access to the urethra
- Cuff placement: Careful positioning around the urethra
- Balloon placement: Usually goes in the pelvis
- Pump positioning: Typically in the scrotum for men
Recovery Timeline
Hospital stay: Most patients need 1-2 days in the hospital
First 6 weeks:
- Device stays turned off for healing
- Catheter drainage for 1-2 days
- Gradual return to normal activities
- Regular doctor visits
Device activation (6-8 weeks after surgery):
- Learning how to use the device
- Pressure adjustments if needed
- Checking how well continence improved
Dr. Anna Kowalski is a reconstructive urologist. She explains that “the waiting period before activation is crucial for proper healing. Patients who try to use the device too early risk problems.”
Comparing Treatment Options
Understanding how artificial urinary sphincters compare to other treatments helps you make informed decisions.
Non-Surgical Treatments
Behavioral changes and exercises are usually tried first:
- Success rates: 30-50% for mild to moderate incontinence
- Advantages: No surgery, no risks
- Limitations: Often not enough for severe incontinence
Medications may help some:
- Certain drugs can improve urethral tone
- Limited help for severe cases
- Potential side effects and drug interactions
Other Surgical Options
Male sling procedures offer another choice:
- Less invasive than AUS
- Success rates: 60-80% for right candidates
- May not provide enough control for severe cases
Urethral bulking agents are minimally invasive:
- Office procedure with minimal recovery
- Success rates: 40-60%, often temporary
- May need repeated treatments
Urinary diversion is for extreme cases:
- Permanent solution but requires lifestyle changes
- Higher risks than AUS
- Usually considered only when other options fail
Dr. Patricia Williams directs the center at Stanford. She notes that “the artificial urinary sphincter often provides the best long-term solution for severe incontinence, especially in patients who’ve failed other treatments.”

Frequently Asked Questions
How long does an artificial urinary sphincter last? Modern AUS devices typically work well for 10-15 years. Device life depends on your activity level, proper maintenance, and individual anatomy. Most patients need at least one device replacement during their lifetime.
Can I have an MRI with an artificial urinary sphincter? MRI safety varies by device model and scanner strength. Most modern AUS devices are MRI-safe under specific conditions. Always tell healthcare providers about your device before any imaging studies.
What happens if the device breaks? Device problems may show up as return of incontinence or trouble urinating normally. Most breakdowns need surgery to fix or replace the device. Contact your urologist right away if you suspect problems.
How soon after surgery can I return to normal activities? Most patients can return to light activities within 2-3 weeks and full activities after 6-8 weeks. The device stays turned off during initial healing, so you won’t see continence improvement until activation at 6-8 weeks.
Will others notice the device? The control pump typically goes in the scrotum for men or labia for women, where it’s not visible. Some patients report mild discomfort initially, but most adapt quickly and find the device unnoticeable in daily life.
Can I play sports and exercise? Once fully healed and activated, most patients can return to previous activity levels. Contact sports may need special consideration. Discuss specific activities with your surgeon.
What if I need other surgeries later? Having an AUS doesn’t prevent other necessary surgeries, but healthcare providers should know about the device. Some procedures may require temporary device deactivation or special precautions.
How often do I need follow-up appointments? Typical follow-up includes visits at 2 weeks, 6 weeks (activation), 3 months, 6 months, and then yearly. You may need more frequent visits if problems arise or adjustments are needed.
Conclusion
The artificial urinary sphincter represents a remarkable achievement in medical technology. It offers hope and restored quality of life for patients with severe urinary incontinence.
While the decision to get AUS surgery requires careful consideration of risks and benefits, the vast majority of right candidates experience significant improvement. Their condition and overall well-being improve dramatically.
As technology advances and surgical techniques improve, the future holds even greater promise. The key to success lies in proper patient selection, experienced surgical teams, and commitment to long-term follow-up care.
If you struggle with severe incontinence that hasn’t responded to other treatments, talk to a qualified urologist who specializes in incontinence. They can help determine whether an artificial urinary sphincter might be right for you.
