Incontinence, also known as bladder weakness, is the involuntary loss of urine. Those affected are unable to hold their urine safely and pass it at the desired place and time.
In principle, a distinction must be made between urinary storage disorders and bladder emptying disorders.
A urinary storage disorder is defined as the inability of the bladder to store a certain volume of urine over a certain period of time.
The classification of urinary storage disorders includes
- sphincter-related stress incontinence,
- bladder-related urge incontinence due to neurogenic or idiopathic overactivity of the bladder muscles,
- mixed incontinence (combined stress and urge incontinence),
- extraurethral incontinence (e.g. fistulas) and
- rare special forms of urinary incontinence.

The degree of stress incontinence is categorized according to severity or the activity during which the incontinence occurs.
- Grade I stress incontinence: Involuntary loss of urine during heavy physical exertion (e.g. coughing, sneezing, pushing)
- Grade II stress incontinence: Involuntary loss of urine even during light physical exertion (e.g. running, climbing stairs, changing position)
- Grade III stress incontinence: Involuntary loss of urine at rest and when lying down
The condition is more common in older people, but younger people also frequently suffer from stress incontinence. This form of bladder weakness mainly affects women.
Bladder incontinence is more common in people with the following risk factors:
- Obesity (obesity),
- Age (oestrogen deficiency after the menopause, dementia, immobility),
- ethnicity (Caucasian > Asian > Negrid),
- multiple pregnancies and vaginal delivery,
- pelvic surgery,
- smoking and
- chronic lung disease.
The diagnosis is usually based on the medical history. However, there are also other methods for diagnosing stress incontinence:
- Micturition diary (logging drinking habits, unintentional and intentional urination),
- Urinalysis (Stix, Uricult),
- Pre-retention test,
- Vaginal adjustment and pH measurement,
- Karyopyknotic index,
- Urethrocystoscopy,
- Cough provocation test with full bladder,
- Urodynamics (cystometry with urethral pressure profile).
- Behavioral modifications,
- pelvic floor training,
- Vaginal and urethral pessaries, vaginal cones,
- electrostimulation, magnetic stimulation (ExMi),
- medication (duloxetine),
- operations:
- Colposuspension (Burch)
- Sling plasty
- Fascia reinsplasty
- Plastic slings (e.g. TVT)
Behavioral modifications primarily include prevention, weight loss and reducing the amount of water drunk in the evening.
With targeted pelvic floor training, around half of all those affected can avoid a planned operation. This training has been proven to improve the symptoms of stress incontinence if it is carried out regularly and on an ongoing basis.
As this form of incontinence mainly affects women, we will focus on the female anatomy in the following text.
The pelvic floor muscles are located on the inside of the pelvis. They surround the urethra, vagina and bowel opening and, together with the sphincter muscles, control the openings. They also ensure the correct position of the urethra.
If these muscles are too slack, the urethra can descend when straining, resulting in uncontrolled urine leakage.
Recognize the correct muscle area with the following exercise
- Squeeze the sphincter muscle as if you wanted to stop the flow of urine.
- When you have contracted the correct muscles, you will feel a slight lifting of the muscles upwards and inwards under the pelvis.
- Other parts of the body (bottom, stomach, inner sides of the lower legs) should not be moved.
Recognized the right muscle area? Then you're ready to go:
Pelvic floor exercise 1
- Spread your legs slightly, place your hands on your buttocks
- Pull the pelvic floor upwards and inwards
- Use your hands to check that you are not using the gluteal muscles
- Tense the muscles as hard as possible for 6 to 8 seconds at a time without straining other muscle groups
- Repeat up to 10 times, perform the exercise 3 times a day
Pelvic floor exercise 2
- Squat down on your spread knees and elbows, toes together, head on your hands
- Contract the pelvic floor muscles in this position
- Tighten the muscles as much as possible for 6 to 8 seconds at a time without straining other muscle groups
- Repeat up to 10 times, do the exercise 3 times a day
Pelvic floor exercise 3
- Lie on your stomach and bend one leg
- Tighten your pelvic floor muscles in this way
- Tense the muscles as hard as possible for 6 to 8 seconds at a time without straining other muscle groups
- Repeat up to 10 times, perform the exercise 3 times a day
Pelvic floor exercise 4
- Lie on your back, legs bent, feet wide apart
- Use your hands on your buttocks and abdomen to control the muscles that should not be strained
- Now tense your pelvic floor muscles
- Tense the muscles as hard as possible for 6 to 8 seconds without straining other muscle groups
- Repeat up to 10 times, perform the exercise 3 times a day
Pelvic floor exercise 5
- Sit cross-legged and keep your back straight
- Now lift the pelvic floor muscles upwards and inwards
- Tighten the muscles as much as possible for 6 to 8 seconds at a time without straining other muscle groups
- Repeat up to 10 times, perform the exercise 3 times a day
Pelvic floor exercise 6
- Legs slightly bent and spread apart
- Support yourself with your hands on your thighs, keeping your back straight
- Now pull the pelvic floor muscles upwards and inwards
- Tense the muscles as hard as possible for 6 to 8 seconds without straining other muscle groups
- Repeat up to 10 times, perform the exercise 3 times a day
There is little data available on pessary or cone therapy. To date, no advantage has been proven for any particular type of pessary. Moreover, pessaries only treat the symptoms and not the cause of the incontinence.
Vaginal cones and biofeedback can reinforce the positive effects of pelvic floor training. Electrostimulation or magnetic stimulation (ExMi) have the same effect.
There are several studies that show that electrostimulation leads to an improvement in stress incontinence. However, there is no higher level of evidence or recommendation for this.
Only one approved serotonin reuptake inhibitor (duloxetine) is currently available for drug therapy. It can also be used "off-label" for male stress incontinence. A positive therapeutic effect has been demonstrated for duloxetine. However, only 10 % of patients became completely continent in large studies.
Minimally invasive surgical methods (TVT and TOT) achieve continence rates of 80 % - 90 %. These rates correspond to those of more invasive surgical methods such as colposuspension according to Burch or fascioplasty.
However, surgery should only be performed after all conservative options have been exhausted.
There are various forms of treatment for stress incontinence. A combination of pelvic floor training with
- biofeedback support or
- electrostimulation or magnetic stimulation and
- drug therapy
usually leads to a significant improvement in symptoms.
Even after surgical treatment, supportive conservative measures are still necessary. These therapy cascades should therefore be recommended and adhered to as part of a holistic approach.
