Do-It-Yourself uroflowmetry – A better way of collecting uroflow data.

A comparison of Do-It-Yourself uroflowmetry (DIY), e.g. an in-home uroflometry (uroflow), with traditional, in-clinic uroflowmetry.

Mombelli et al presented a study that compares home uroflowmetry to the traditional commonly used uroflow.

The assessment of urine flow rate dates back to the 1950s…
There is nothing new in Lower urinary tract symptoms, prostate volume and uroflow.

The title of the study: Free uroflowmetry versus “Do-It-Yourself” uroflowmetry in the assessment of patients with lower urinary tract symptoms.

To sum it up: together with the international Prostatic Symptom Score (IPSS), home uroflow is a good estimate of the results of uroflowmetry. In other words, it enables unnecessary hospital investigations to be avoided.

How long does a uroflow take?

The procedure usually takes about half an hour. According to the availability in your region, the test is typically performed in a hospital or a physician’s office. Your doctor may ask you to repeat the process in case the results are not valid. In other words, you’ll have to drink until you fill your bladder, then wait a while and measure again.

Can a stopwatch and a liquid container replace the conventional uroflow machine? Mombelli et al published the paper in 2014, a few years have passed, and it seems that urologists still prefer precise data. Uroflow is no longer limited to only the hospitals and clinics that have the technology.

The stopwatch, DIY, method provides a very general idea of the bladder state. However, home uroflow is a better way to obtain (multiple) flow readings. To clarify, it has the potential to combat problems inherent to clinic-based flow tests.

Likewise, there are several studies that show the use of low cost home devices to measure flow rate. But there is no need to compromise where it comes to health or test accuracy. With iUFlow you can measure and monitor your urine flow at home and turn it into valuable data. The data helps doctors to easily diagnose and treat urinary tract conditions. The device is lightweight and portable. There is no need to touch or write down urination volume.

A flow test calculates the speed of urine flow over time.

Just place iUFlow device on the toilet bowl under the seat, make sure it’s stable with all 3 flaps touching the bowl. And that’s it. The next step is urinate into it and flush. It will quickly and accurately measure the flow and total volume.

The results will sync into your iPhone or Android. On your smartphone, turn on Bluetooth and start iUFlow app. In addition, your doctor can view the flow rate outcomes on their computer screen.

By viewing the dashboard, your doctor can now assess your treatment with real-time data and get constant feedback from your bladder. And to even monitor or determine the need for treatment. A great use of this valuable data is by comparison. For example, before and after drug like alpha blocker for instance in the case of BPH. Urine Flow Rate Detector or Home Uroflow can be valuable as well for the monitoring of other situations. For example, OAB, USD.

Is low Qmax value a sign of obstruction? Why is my urine stream weaker? do I need a bladder app?

How to get the test results of iUFlow? Does it measure volume and Qmax?

Both Volume and Qmax are recorded, of course. iUFlow syncs the result to iUFlow Voiding Diary app (free and on both Android® and Apple®). And the same for iUFlow dashboard. So, your physician can interpret the results even at the same moment that the measurement takes place.

BPH Patient consulting with an online Urologist. Not an exciting chat

More and more online doctor services are emerging. Let’s take a look at this correspondence of a BPH patient and an online Urologist (below). Firstly, as you can see, the answers are generic. Secondly, he received a grocery list of possible issues and treatments. Thirdly, it seems that the online doctor is confusing between Benign prostatic hyperplasia (BPH) and Urge incontinence??.

To sum it up, an online doctor can’t replace a visit at the Urologist’s or PCP’s clinic.
(TL;DR) Avoid online doctor services and don’t try to save money on your bladder.

Weak Flow? A sign of BPH?

online doctor bph

BPH Patient: I am a 58 years old male. Why does it take me a long time to pee recently? No burning sensation. Urine is not coming easily. Slow urine flow.

Doctor ###### replies:

Hello, my name is Dr #####, thank you for your question. I am a qualified MD with 13 years’ experience, and I am happy to work with you on this.

You should approach a doctor for this.
There are several types of male incontinence like Stress incontinence, Urge incontinence, Overflow incontinence and Functional incontinence.

Causes for incontinence are:
Small functional bladder capacity (FBC): In other words, the bladder is able to contain only a small volume of urine,
Detrusor Overactivity: the muscle of the bladder is hyperactive, causing inappropriate urination.
Sleep disorders: such as sleep apnea and sleep walking, etc. can lead to this.
Medications: certain medications can cause this.
UTI: urinary tract infection can cause this.
Urinary tract stones
Neurological disorders

Consult a Urologist for this.

A urologist needs to investigate to find the cause of your incontinence. You need to be examined thoroughly for this. In addition, besides tests like Urine Culture and sensitivity, you also need tests like Uroflow, Ultrasound, IVP, cystoscopy and voiding cystography. You should discuss these tests with your doctor

You need to take some active steps to combat such habits:
Pelvic exercises: Kegel exercises should be done.
Link: https://medlineplus.gov/ency/patientinstructions/000141.htm
Biofeedback exercises.
Behavior modifications: Like going to the bathroom at fixed times, drinking less fluids, holding on to the urine as far as possible till the time is appropriate.
These steps will help you, but you need to see a Urologist for this.
Hope I have been able to clarify the situation for you and helped in resolving your query. If you need more help, please let me know so l can continue to assist you.
Thank you and I wish you the best of health – stay safe!


An online chat will never replace a real face-to-face visit with a Urologist or Gynecologist. It is better to arrive prepared. That is to say, share objective data with your doctor. Such as: bladder diary and uroflow charts. Your health care provider will very much appreciate these. And, like this, your complaints can be assessed scientifically as symptoms.

Weak Urine Flow? A sign of BPH for men?

iUFlow Overview

How to read Uroflow results?

What is Uroflow?

Uroflow vs. Uroflowmeter vs. Uroflowmetry vs. ?

Firstly, yes it is a bit confusing. But, these are all the same. Uroflowmetry is a diagnostic assessment of the urinary tract functionality. Your Urologist or physical therapist suggest performing a uroflow test, in case they suspect that you are suffering while urinating, or have a weak flow rate (stream).

Uroflow, or Uroflowmetry is a test to measure the flow (rate) of micturition. During the test, the uroflow device, a Uroflowmeter, tracks urine flow in mL/sec. It reports Urination volume, meaning, how much urine flows out. It is that simple. Urination Time in seconds, means, How long it takes to urinate.

Interpretation of uroflowmetry results

What is Qmax?

While we measure the total volume of the urination is in mL (milliliter), the flow rate is measured in mL/second, and the Qmax is the value of the highest flow rate measured during the test. In other words, Qmax is the fastest stream measured in mL/s.

Weak flow = Low Qmax

Slow urination speed = Low Qmax

Flat urination chart = Low Qmax

What is Qmax illustration of Uroflow results

The image above shows a curve with a changing flow to illustrate TQmax, Flow time and Qmax values. If you identify a high Qmax, it is unlikely to be a curve from someone with a blockage or obstruction of the urinary tract and weak flow.

Low Qmax value is commonly a sign of obstruction. It is a common symptom of BPH. In men – Benign prostatic hypertrophy. Enlargement of the prostate gland, or block of the urethra. Also, it can point to another abnormality related to the Lower Urinary Tract.

QmaxInterpretation *

General ‘rule of thumb’ interpretation. Please advise your doctor.

Can you describe the normal flow rate of urine?

Visually it is a bell-shape-like chart. During normal voiding, the initial stream starts slowly. It accelerates until the bladder is almost empty. The flow then slows until the bladder is empty. In patients with a urinary tract obstruction, this pattern of urine flow is changed, and increases and decreases more slowly.

How exactly is a urine flow test performed?

In a clinic, with the conventional method, a nurse will ask you to urinate into a funnel-shaped container placed on a scale-like electronic device. It is important to know that you can not put any toilet paper in the toilet or device.

After your bladder is full, you’ll need to pee normally without manipulating the speed. A conventional electric uroflowmeter hooked up to the toilet record the flow rate and quantity of urination. And of course, never urinate until the machine is on and ready.

Then, when you’ve finished the machine will send or print your results to your doctor. The uroflow test can help the doctor in identifying the causes of urinary difficulties.

Weak Urine Flow? a sign of BPH for men, or Cystocele? Better approach

Slow starting or problems with keeping a steady flow stream affect women and men.

The common cause of weak urine flow in men is BPH. BPH is Benign prostatic hyperplasia. In many cases, weak stream is a symptom of a bladder that isn’t emptying normally. In the case of BPH, the enlarged prostate causing a partial block of the tube that carries urine out of the penis (the Urethra). A ‘slow’ Uroflowmetry chart (Qmax) is commonly a clear sign. It is a visualization of a weak urine flow rate.

Unstressed muscles can cause the bladder to not fully discharge. Suffering from a disease related to the nervous system? For example: Parkinson’s or MS (Multiple Sclerosis) the risk is higher for bladder and urination issues.

iUFlow BPH description

Bladder Prolapse

For women, bladder prolapse, or cystocele, is the main cause for urination flow issues. The bladder leaks and bulges through the pelvic floor muscles into the vagina.

Other bladder related situations can point to incontinence, overactive bladder (OAB), UTI and kidney malfunctioning.

If you’re suffering from symptoms like: painful urination, cloudy urine or blood in your urine > these are clearly a sign to call for help.

Your Urologist or Physical therapist in clinic will likely be interested to get objective data about your bladder behavior – in the form of a bladder diary and Uroflow test. With the iUFlow device and app, you can come prepared and provide both accurately. This can make the diagnosis process to be much shorter and more precise.

How PT and Urologists get real-time data on their patients’ progress.

Dr. Delaney’s lecture scripted:

All condition associated with LUTS need a Bladder Diary.

Any condition associated with lower urinary tract symptoms needs a bladder diary. What I’ve found with the iUFlow is that: normally, where compliance with the bladder diary is less than 50%. And that’s less than 50% of people actually even make any attempt.

Only < 10% would actually do an accurate Bladder Diary

But you know, I’d say, probably really less than 10% would actually do an accurate Bladder Diary in terms of everything they’ve drunk and everything they’ve peed in a 72-hour period. With iUFlow, I’m finding the compliance rate, for at least voided volumes is well over 50%. Like it’s probably close to 90% and then a lot of them are putting in all their fluids and their bowel function. So I’m finding that the accuracy of the data we’re getting is so much better. The patients find it really, really, easy to use. Because they don’t need to measure anything. They don’t really need to clean anything. And from my point of view, the reliability of the data and the compliance is much better.

I use it as a diagnostic tool

I use it for a lot of feedback as a diagnostic tool. It really improves diagnosis. Because we’re also getting them to void in their normal situation. So we’re getting a lot of that artifact that trying to get patients set up for a flow in the office. You know how they come in with a full bladder, and they’re not too urgent that the flow machine is actually ready for them to go at the right time. So we really get, superb quality data. We get the quantitative assessment of the volume and flow. And so I really think it gives me accuracy of diagnosis.

The amount of data you get over a week, might seem excessive initially. But once you get used to reading the report, really you can read it in less than a minute. And get a great picture of what’s going on.
