The article in brief
A urodynamic assessment is a thorough medical examination to assess the function of the bladder and urinary sphincter. Here are the key points to remember :
- Allows you to diagnose persistent urinary problems
- Composed of three tests: flowmetry, cystomanometry and urethral profilometry
- Hard between 30 minutes and 1 hourwithout hospitalisation or anaesthetic
- Requires specific training and may cause slight temporary discomfort
- Crucial for adapt treatment in a personalised way
Le urodynamic testing is an essential test for diagnosing urinary disorders. As an experienced urologist, I regularly carry out this test for my patients. Allow me to explain to you in detail what this test is, how it is carried out and its usefulness.
What is a urodynamic assessment?
Le urodynamic testing is a thorough medical examination to assess the function of the bladder and urinary sphincter. It is prescribed when patients have persistent urinary symptoms such as :
- Bladder weakness
- Frequent urination
- Urgent cravings
- Pain when urinating
- Difficulty emptying the bladder completely
This examination is crucial for identify the symptoms that require urgent consultation with a urologist. I remember a patient who had suffered for years from frequent urination without finding a solution. Thanks to the urodynamic assessment, we were able to identify the precise cause of his problem and put in place an effective treatment.
Objectives of urodynamic assessment
The main aim of this examination is to understand the mechanisms behind urinary problems. It enables us to :
- Measuring pressure in the bladder and urethra
- Assessing bladder capacity
- Analysing the functioning of the urinary sphincter
- Detect any involuntary bladder contractions
Examination duration and conditions
The urodynamic assessment generally lasts between 30 minutes and 1 hour. It does not require hospitalisation or anaesthesia, which is reassuring for many patients. The examination takes place in the gynaecological or semi-seated position, depending on the patient's comfort.
How does a urodynamic assessment work?
Le urodynamic testing consists of three main tests: flowmetry, cystomanometry and urethral profilometry. Each step provides us with valuable information about the functioning of your urinary system.
Flow measurement
Flowmetry is the first stage in the assessment. It involves urinating into a special device that measures the flow and volume of urine. It's a simple, non-invasive test that gives us valuable information about the strength of the urine stream and the capacity of the bladder.
Cystomanometry
Cystomanometry is the central stage of the assessment. Here's how it works:
- Introduction of a thin catheter through the urethra to the bladder
- Progressive filling of the bladder with sterile water
- Measuring pressure in the bladder at different volumes
- Sometimes a rectal probe is inserted to measure abdominal pressure
This stage can be slightly uncomfortable, but it is rarely painful. I always make sure to explain each step to my patients to reassure them.
Urethral profilometry
The final stage involves gradually withdrawing the catheter from the urethra while measuring the pressures. This allows us to assess the resistance of the urethra and the function of the urinary sphincter.
Preparing for and following a urodynamic assessment
Good preparation is essential for reliable results. Here are a few tips that I always give to my patients:
| Before the exam | After the examination |

It is normal to experience some discomfort after the examination, such as slight burning when urinating for 1 to 2 days. However, if you experience persistent pain, fever or difficulty in urinating, please contact me as soon as possible.
Le urodynamic testing is a valuable test for diagnose and treat urinary disorders effectively. It allows us to tailor treatment to each individual patient. Don't hesitate to talk to your doctor if you suffer from persistent urinary problems.
