Uroflowmeter, Uroflowmetry or uroflow?
Uroflowmetry is conducted by urinating into a designated urinal, toilet, or wireless apparatus equipped with a built-in measuring device (uroflowmeter). Uroflow refers to the actual flow of urine during voiding.
A uroflowmeter is a device that measures the uroflow. older versions consists of a funnel that attaches to a collection container, and electronic sensors that measure the rate of urine flow. Modern versions can be fitted on a normal toilet.
Uroflowmetry is the process of measuring and analyzing the uroflow data collected by the uroflowmeter. The data is typically displayed on a graph, which can be used to diagnose and monitor various urinary conditions.
Uroflowmetry is a noninvasive, diagnostic procedure used by urologists and nurses to assess and measure the flow of urine during urination. Uroflowmetry is also a test to assess how well the urinary tract functions and can be used for diagnosis, follow-up after surgery or during treatment.
Urine flow rate, also known as urinary flow rate, refers to the volume of urine excreted during urination over a specific time interval.
The Evolution of Uroflowmetry: A Brief History
Willard M. Drake, Jr. invented the modern uroflowmeter in 1946 while at the Jefferson Medical College. In 1948, the Journal of Urology published Drake’s original manuscript titled “The uroflometer: an aid to the study of the lower urinary tract.” Drake received a US patent for the device, called the “Uroflowmeter,” in 1953.
The device is the most commonly used urodynamic instrument in urology clinics and remains an essential tool for diagnosing and managing lower urinary tract symptoms, even 70 years after its invention. (source)
How does a modern and wireless/cloud uroflowmeter system look like?
The modern uroflowmeter is compatible with any standard toilet and can be connected wirelessly to the cloud via a gateway. One such gateway is the Minze Gateway, which links the wireless Bluetooth uroflowmeter to a cloud platform through a wifi connection. The clinician can view the measurements in real-time on their portal, enabling prompt analysis and diagnosis.

What parameters is a uroflowmeter measuring and how to Interpret the uroflowmetry results?
The uroflowmeter measures several parameters related to the flow of urine
- Flow rate: Flow rate refers to the volume of urine expelled per unit of time (mL/s). This can be further divided into average flow rate (total volume divided by flow time) and maximum flow rate (Qmax), which is the highest flow rate achieved during micturition. Qmax is particularly important for assessing the presence of obstructions, such as an enlarged prostate.
- Volume: Volume represents the total amount of urine excreted during a single micturition event, typically measured in milliliters (mL). This parameter helps assess bladder capacity and overall function.
- Average flow rate (Qave) is calculated by dividing the voided volume by the flow time. However, if there are interruptions in urine flow or a terminal dribble, caution should be taken when interpreting the average flow rate.
- Flow time (duration of urine flow), time to reach maximum flow (TQmax)
- Voiding time (total time spent urinating).
The uroflow curve (the graphical representation of the flow rate over time during the voiding process) typically consists of three phases:
- The initial phase: At the beginning of the voiding process, there is a brief period of low flow rate as the bladder fills with urine and the urinary sphincter muscle relaxes.
- The intermediate phase: The flow rate increases gradually to a maximum during this phase, reflecting the force of bladder contraction.
- The terminal phase: As the bladder empties, the flow rate decreases again, and there may be intermittent periods of low flow rate as the bladder contracts to expel the last drops of urine.
In addition to Qmax, the shape of the uroflow curve can provide additional information about urinary system function. For example, a curve with a prolonged or plateaued intermediate phase may indicate bladder outlet obstruction, while a curve with a reduced or absent intermediate phase may indicate a problem with bladder contractility.
How to Interpret of uroflowmetry results?
The interpretation of uroflowmetry results depends on several factors, including age, gender, and overall health status. Generally, a “good” uroflowmetry result is one that falls within normal ranges for the individual’s age and gender, while a “bad” result may indicate an underlying urinary tract problem that requires further evaluation and treatment.
For men, a normal peak flow rate (Qmax) is typically between 10 and 20 mL/s, while for women, it is typically between 15 and 25 mL/s. A lower Qmax may indicate a blockage or obstruction in the urinary tract, such as from an enlarged prostate gland in men or pelvic organ prolapse in women.
In terms of voided volume, a normal range for men is typically between 250 and 500 mL, while for women, it is typically between 200 and 400 mL. Higher or lower voided volumes may indicate an underlying urinary tract problem, such as bladder dysfunction or urinary retention.
What is a normal Qmax in uroflowmetry?
The interpretation of uroflowmetry results depends on several factors, including age, gender, and overall health status and voided volume.
|higher than 15ml/sec
|is lower than 10ml/sec
|Obstruction or weak detrusor
The Purpose of the Liverpool Diagram in Uroflowmetry Evaluation.
The Liverpool Nomogram, created by Haylen and colleagues in 1989, is a diagnostic tool that plots voided volume against peak flow to assess voiding efficiency.
The Liverpool Nomogram is a graph that is used to evaluate uroflowmetry results. It is used to assess bladder function by plotting voided volume against peak flow rate (Qmax). Healthcare providers can use the graph to determine if a patient’s uroflowmetry results are within normal limits for their age and sex, or if further evaluation is needed.
A uroflowmeter is capable of detecting a range of symptoms and conditions that are associated with urinary disorders.
Uroflowmeters are valuable diagnostic tools for assessing urinary flow dynamics and detecting a variety of symptoms and diseases related to urinary disorders. Some common conditions that can be identified using uroflowmetry include:
- Benign Prostatic Hyperplasia (BPH): Enlarged prostate can cause obstruction in the urinary tract, leading to reduced flow rates and other urinary symptoms. Uroflowmetry can help detect and monitor BPH.
- Bladder outlet obstruction: Uroflowmetry can help identify obstructions in the bladder outlet, which can be caused by various factors, such as urethral strictures or prostate enlargement.
- Neurogenic bladder: Uroflowmetry can help identify and assess bladder dysfunction caused by neurological disorders, such as spinal cord injury, multiple sclerosis, or Parkinson’s disease.
- Detrusor underactivity: This condition involves weak or poorly coordinated bladder muscle contractions, leading to inefficient emptying of the bladder. Uroflowmetry can help detect detrusor underactivity and guide treatment.
- Urethral stricture: A narrowing of the urethra can cause reduced urinary flow and other symptoms. Uroflowmetry can assist in diagnosing urethral strictures and monitoring their progression.
- Vesicoureteral reflux: Uroflowmetry can help detect abnormal backflow of urine from the bladder to the kidneys, which may lead to urinary tract infections and kidney damage.
- Interstitial cystitis: Also known as painful bladder syndrome, interstitial cystitis can cause chronic pain and urinary symptoms. Uroflowmetry can aid in the diagnosis and management of this condition.
- Post-surgical evaluation: Uroflowmetry is often used to assess the success of surgical procedures, such as prostatectomy or urethral reconstruction, by monitoring changes in urinary flow dynamics.
How representative is one in-hospital uroflowmeter measurement?
One in-hospital uroflowmeter measurement can sometimes provide useful information about a patient’s urinary flow rate and volume, but it may not be fully representative of their typical urinary function. This is because the stress and anxiety associated with being in a clinical setting can sometimes affect a patient’s urinary flow, leading to inaccurate results.
A comfortable environment such as a normal toilet could help to obtain the most representative results. That’s exactly what Minze Hospiflow has been designed for.
Additionally, urinary flow can be influenced by various factors, such as hydration levels, time of day, and medication use. Thus, multiple measurements taken over time may be necessary to obtain a comprehensive understanding of a patient’s urinary function. To address this need, Minze Health has developed the Homeflow uroflowmeter, which allows patients to take measurements at home over time to better track their urinary function.
Modern software can help urologists determine normal results.
Modern software can help urologists determine normal uroflow results by providing an automated analysis of uroflowmetry data and can aid in the analysis of uroflowmetry data is by providing a Liverpool nomogram overlay, which allows for quick and easy identification of abnormal flow rates. The Liverpool nomogram is a graph that plots voided volume against peak flow rate.
The software can also help identify other abnormalities in the uroflowmetry curve, such as a plateau or staccato pattern, which may indicate bladder outlet obstruction or detrusor dysfunction. Additionally, the software can provide a comparison of the patient’s uroflowmetry results to age and sex-matched normative data, which can aid in diagnosis and treatment planning.
Deviated uroflow curves
plateaued intermediate phase
A plateaued intermediate phase on a uroflow curve refers to a portion of the curve where the urine flow rate remains relatively constant for an extended period of time. This can indicate a problem with bladder outlet obstruction, which can occur when there is a blockage in the urethra that prevents urine from flowing freely out of the bladder.
When there is a blockage in the urethra, the bladder may have to contract more forcefully to overcome the obstruction and push urine through the narrow passage. This increased pressure can cause the flow rate to initially increase, but once the bladder reaches its maximum contraction strength, the flow rate may plateau and remain relatively constant for a period of time, before eventually decreasing as the bladder empties.
In some cases, the plateaued intermediate phase may be followed by a rapid drop in flow rate as the bladder empties completely. This drop in flow rate is called the terminal phase, and it typically occurs as the bladder is nearly empty and the urine stream tapers off.
Overall, a plateaued intermediate phase on a uroflow curve is an important sign of bladder outlet obstruction, and it can help clinicians identify and diagnose conditions such as benign prostatic hyperplasia (BPH), urethral strictures, and bladder neck contractures.
A “staccato” shape on a uroflowmetry curve
A “staccato” shape on a uroflowmetry curve refers to a pattern of urine flow that is characterized by a series of intermittent peaks and valleys, rather than a smooth and uninterrupted flow. This type of uroflow curve can be indicative of a condition called detrusor-sphincter dyssynergia (DSD), which is a type of voiding dysfunction that occurs when the bladder contracts forcefully, but the urinary sphincter muscle fails to relax, leading to incomplete bladder emptying.
The staccato pattern on a uroflowmetry curve can be seen as a series of peaks and valleys that occur at irregular intervals, with the peaks representing episodes of high urine flow and the valleys representing periods of low or no urine flow. This pattern is often associated with a prolonged intermediate phase and a reduced maximum flow rate, as the bladder contracts more forcefully to overcome the resistance caused by the dysfunctional urinary sphincter.
While a staccato pattern is often associated with DSD, it is important to note that other conditions, such as neurological disorders, can also cause similar patterns on a uroflow curve. Therefore, a comprehensive evaluation, including a physical examination, patient history, and other diagnostic tests, may be necessary to determine the underlying cause of the staccato pattern and develop an appropriate treatment plan.
A tapered curve on a uroflowmetry test is characterized by a gradual decrease in urine flow rate over time, usually towards the end of the voiding process. This type of curve can be an indication of a problem with bladder contractility or bladder outlet obstruction.
Bladder contractility refers to the ability of the bladder muscle to contract forcefully during urination, in order to expel urine from the body. If the bladder muscle is weak or unable to contract effectively, it may result in a decreased urine flow rate, leading to a tapered curve on the uroflowmetry test.
On the other hand, bladder outlet obstruction refers to a blockage in the urinary tract that prevents urine from flowing freely out of the bladder. This can be caused by a variety of conditions, such as prostate enlargement, urethral strictures, or bladder neck contractures. The obstruction can cause the bladder to work harder to push urine out, leading to a tapered curve as the bladder muscle becomes fatigued and the urine flow rate decreases over time.

Potentially billions of people many people suffer from Lower urinary tract symptoms (LUTS).
Lower urinary tract symptoms (LUTS) are a common health problem, particularly among older adults. According to the World Health Organization (WHO), around 50% of men and women over the age of 50 experience some form of LUTS.
The most common lower urinary tract symptoms include:
- Urinary frequency: the need to urinate more often than usual.
- Urgency: the sudden and strong need to urinate.
- Nocturia: waking up at night to urinate.
- Hesitancy: difficulty starting urine flow.
- Weak stream: a decreased force of urine stream.
- Incomplete emptying: feeling as though the bladder is not fully emptied after urination.
- Urinary incontinence: loss of bladder control, resulting in leakage of urine.
While LUTS are more common among older adults, they can also affect younger individuals and can be caused by a variety of factors, including urinary tract infections, prostate problems, neurological disorders, and certain medications. It is important to seek medical attention if experiencing any persistent or bothersome lower urinary tract symptoms.
Typical causes of urinary tract symptoms.
Lower urinary tract symptoms (LUTS) can be caused by a variety of factors, including:
- Benign prostatic hyperplasia (BPH): This condition, which is more common in older men, occurs when the prostate gland becomes enlarged and obstructs the flow of urine.
- Urinary tract infections (UTIs): Infections in the bladder, urethra, or kidneys can cause symptoms such as pain, urgency, and frequency of urination.
- Neurological conditions: Conditions that affect the nervous system, such as multiple sclerosis, Parkinson’s disease, and spinal cord injuries, can interfere with the normal functioning of the bladder and lead to LUTS.
- Medications: Certain medications, such as diuretics and antihistamines, can cause LUTS as a side effect.
- Lifestyle factors: Factors such as obesity, smoking, and alcohol consumption can increase the risk of developing LUTS.
- Other medical conditions: Medical conditions such as diabetes, chronic kidney disease, and bladder stones can also cause LUTS.
The important to detect Benign prostatic hyperplasia (BPH) in an early stage
It is important to detect Benign prostatic hyperplasia (BPH) in an early stage, as early detection can help with prompt treatment and management of the condition. BPH is a common condition that can cause lower urinary tract symptoms (LUTS), such as increased frequency and urgency of urination, weak urine flow, and difficulty starting or stopping urination.
If left untreated, BPH can lead to complications such as urinary tract infections, bladder stones, and kidney damage. Early detection and treatment can help prevent these complications and improve quality of life for those with BPH.
- Frequent or urgent need to pee, also called urination.
- Peeing more often at night.
- Trouble starting to pee.
- Weak urine stream, or a stream that stops and starts.
- Dribbling at the end of urination.
- Not being able to fully empty the bladder.
Less common symptoms include:
- Urinary tract infection.
- Not being able to pee.
- Blood in the urine.
The symptoms of BPH tend to slowly get worse. But sometimes they stay the same or even improve over time. The size of the prostate doesn’t always determine how serious the symptoms are. Some people with slightly enlarged prostates can have major symptoms. Others who have very enlarged prostates can have minor problems. And some people with enlarged prostates don’t have any symptoms at all.
Other possible causes of urinary symptoms:
- Urinary tract infection.
- Inflamed prostate.
- Narrowing of the urethra, the tube that carries urine out of the body.
- Scarring in the bladder neck due to past surgery.
- Bladder or kidney stones.
- Problems with nerves that control the bladder.
- Cancer of the prostate or bladder.
- Some medicines also may lead to symptoms that seem like those caused by BPH, including powerful pain-relieving medicines called opioids, cold and allergy medicines, and older medicines for depression called tricyclic antidepressants.
Other aparatus typically used in conjuntion with a uroflowmeter
Several apparatus can be used in conjunction with a uroflowmeter to provide a more comprehensive assessment of urinary function. These may include:
- Cystoscope: A cystoscope is a thin, tube-like instrument with a light and camera that is used to examine the inside of the bladder and urethra. Cystoscopy may be used in conjunction with uroflowmetry to evaluate the structure and function of the bladder and urethra and to identify potential causes of urinary symptoms.
- Automated bladder diary: During an automated bladder diary, a patient can automatically collect information such as the time and volume of each void, any incidents of urinary leakage, and any associated symptoms such as urgency or pain. This information can provide valuable insights into the patient’s urinary habits and patterns, and can help healthcare providers identify potential triggers or patterns that may be contributing to urinary symptoms.
- Post-void residual (PVR) volume measurement device: A PVR measurement device is used to assess the amount of urine that remains in the bladder after urination. This test may be used in conjunction with uroflowmetry to determine if the bladder is emptying completely during urination.
- Urodynamic testing equipment: Urodynamic testing equipment is used to evaluate the function of the bladder and urethra during filling and emptying. This test may be used in conjunction with uroflowmetry to provide a more detailed assessment of bladder function and to identify potential causes of urinary symptoms.
- EMG (electromyography) equipment: EMG equipment is used to measure the electrical activity of muscles, including those involved in urination. EMG may be used in conjunction with uroflowmetry to evaluate the strength and coordination of these muscles.
