Understanding Stress Urinary Incontinence (SUI)


Your urinary tract includes the kidneys, ureters, bladder, and urethra.

Your kidneys make urine, which flows through the ureters to your bladder.

Your bladder expands to store urine until you’re ready to urinate.

Muscles, called sphincters, contract to hold urine in your bladder.

When you urinate, the sphincters relax.

This allows urine pass to out of your body through your urethra.

Strong pelvic floor muscles support your bladder and other organs so they can work properly.

Stress urinary incontinence means urine leaks by accident when movement puts sudden pressure on your bladder.

It can happen when you: cough, laugh, sneeze, or exercise.

Urine can leak if your sphincters or pelvic floor muscles have become weak.

Things that can weaken these muscles include: childbirth, obesity, aging, pelvic surgery, and some types of medicine.
