I love the TV show Mythbusters, I have for the last 15 years, (yes ladies, gents it has been on for that long). If you aren’t familiar with this show, the hosts Adam and Jamie, try to prove or disprove popular myths like, is shooting fish in a barrel easy? Spoiler alert: yes, but maybe not in the way you think it is. I’ll let you look that one up on your own. I loved how this show took everyday assumptions and applied real science to see if they were indeed true. In the same spirit of my beloved show, we are going to try and bust some pelvic floor myths. Since I don’t have the funding or ethical review board to conduct large-scale experiments on pelvic floor questions, I am going to the next best (albeit, slightly less glamorous thing) and see what I can find on PubMed, while applying known pelvic floor science to the question. Most of us have probably been told that holding in your pee for a long time can cause urinary tract infections (UTIs), but is it actually true? Can peeing at every single urge cause other problems? Through gathering the available evidence we will look at this time old axiom to determine whether it is true or false.
What is a UTI (Urinary Tract Infection)
A UTI occurs when bacteria colonize or grow in your urinary system, which is composed of your bladder, urethra, ureters, and kidneys. Usually, we see these infections in the bladder. People with female anatomy tend to get UTIs more often at an 8:1 ratio to their counterparts with male anatomy. This is because the male urinary system has a substantially longer urethra, as well as the fact that in individuals with female anatomy urethral position makes it vulnerable to bacterial colonization. Although it is more common for adults to contract UTI’s, children can too. UTI’s in children can be an indicator of possible bladder conditions, such as vesicoureteral reflux (when urine seeps back into the upper part of the urinary system and can cause infections in the kidneys). Any bladder infection in children should be followed up by imaging to rule this condition out. Untreated reflux can be harmful to the kidneys. Much of the literature I reviewed pertains to people with female anatomy with UTIs but it is possible to apply some of this information to males. That being said, at least half of people with female anatomy will report a UTI at some point in their lifetime.
We can further classify UTI’s by how often one contracts them. Recurrent UTI is defined as 3 positive cultures in 12 months or 2 positive cultures within 6 months. Uncomplicated infection occurs in people who have a normal urinary tract, whereas a complicated infection occurs in individuals with complications in the urinary tract, such as vesicouretral reflux.
Known Risk Factors for UTI
Our main question is, “does holding pee cause UTI’s?”, but what things do we absolutely know are risk factors for UTIs? First thing is having a female urinary tract. The female urethra (where the pee comes out) is shorter than the male’s, making it easier for UTI causing bacteria to get a foothold and cause infections. Along those lines, having receptive vaginal intercourse can make you more prone to get a UTI because objects inserted into the vagina can introduce bacteria to the urethra, which live nearby each other. Pregnancy, diabetes, and immunosuppression have also been shown in the literature to increase the chances of getting a UTI. Being post-menopausal can also increase your risk of developing a UTI as it may thin the tissue of the vulva and make it easier for bacteria to get to the bladder. Other factors include the use of spermicides, catheterization (both indwelling and intermittent), wiping back to front , diaphragm use, or incomplete bladder emptying.
But Does Holding Your Pee Cause UTIs???!!!!!
Yes… and no. The data out there is pretty darn sparse, and what I’ve read has not provided any clear-cut studies examining the issue. Keep in mind it’s a pretty hard experiment to design to prove that holding your pee can cause UTIs. Peeing as a preventative to reduce UTIs works by flushing out the urethra, but you need a good amount of liquid (however don’t force or push out your pee) to clean it out. This is why I advise and will continue to advise patients to pee after intercourse. It flushes everything out.
Now, that being said, if you are peeing too frequently, and only a little bit comes out at a time, you may not be effective in cleaning out your urethra fully. Normal bladder frequency should be about once every 2-3 hours and that is if you drink 7-8 glasses of fluid a day (if you drink less than that then frequency will be less). And, obviously, things will pick up a bit if you’ve had a bunch to drink, (water or otherwise), but that’s the average. Another way to tell if you are on track is if you are peeing for 8-10 seconds (real “one-Mississippi” seconds) and it is a strong, consistent stream. If you train yourself to pee when you don’t have a large amount of pee in the bladder, you could actually be training your bladder to be more frequent, which can be a problem.
What if when you are peeing, you have to strain and only have a dribbly stream and not a lot comes out? This is a problem that could lead you to get UTIs. It is called incomplete emptying. Incomplete emptying happens when the bladder does not empty properly. Because of this, urine is not expelled out of the urethra at a rate that is sufficient to clean out the urethra and that means bacteria may have an easier time getting to your bladder. Symptoms of incomplete emptying can include post-void dribble, having to strain to pee, and or feeling like you have to pee again shortly after your first attempt to pee.
Does Pelvic Floor Health Have Anything to Do with UTIs
It can. Also, problems in the pelvic floor can commonly mimic symptoms of UTIs (burning with urination, frequency, urgency, etc.,.). The pelvic floor is a group of muscles between the tail-bone and the pubic bone, and they surround the urethra, bladder, anorectal opening, and genital region. For people with incomplete bladder emptying, a tight pelvic floor may be playing a role. The pelvic floor has many functions, but one of its functions is to open and close the doors (sphincters) that hold pee in and let it out. If the pelvic floor is tight, it’s hard for the muscles to relax and for the pee to exit. More importantly, when the pelvic floor is held in tension it prevents the detrusor (bladder squeezer muscle) from emptying the bladder well.
Additionally, tight pelvic floor muscles, specifically in the urogenital diaphragm layer (the superficial pelvic floor muscle layer), can feel a lot like a UTI when they are tight. Some people with female anatomy will experience irritation in this area after intercourse, which can feel a lot like a bladder infection. People with female anatomy who repeatedly test negative for UTI’s but have symptoms could have pelvic floor dysfunction! It’s wild, I know.
Bladder Tips for us All
Wash yourself and your partner before sex
If you have a vagina, wash your vulvar area with water before getting it on. The fact of the world, is we are covered in bacteria, if you wash your vagina and vulva before anything goes in it, you lessen the chance of bacteria getting pushed into your urinary tract. Your partner should also wash their fingers, toys, or penis as well to avoid infection. Using a USDA organic mild soap with no extra ingredients or additives is best.
Pee After Sex!
Pee after sex. It is so important. It’s better to have a bladder that’s more full than not, so you can clear out that urethra, but regardless try and pee relatively soon after having sex.
Wipe Front to Back
Please excuse me for being indelicate, but if you wipe back to front (anus to vagina), you are helping to drag poo bacteria up towards the urethra, which is something we definitely don’t want to do while we are trying to prevent UTI’s.
Test your Urine
If you have symptoms of a UTI, get yourself to the doctor, nurse practitioner, physician’s assistant, etc. They can see if you really do have an infection. The importance of this is two-fold. To nab an infection before it gets worse or goes to your kidneys, and to make sure you actually have an infection, not pelvic floor dysfunction. Making sure you get your urine tested also ensures you won’t have to take unnecessary antibiotics which can negatively affect yeast and gastrointestinal symptoms.
If you have symptoms and no infection or trouble emptying your bladder, come to physical therapy!
UTI symptoms that aren’t a UTI are often caused by pelvic floor dysfunction. A skilled pelvic floor physical therapist will be able to assess whether or not your pelvic floor is playing a role in what you are feeling. A skilled pelvic floor physical therapist will assess whether or not you can open and close your pelvic floor well in order to pee effectively as well as checking the pelvic floor for tightness and for any nerve irritation. If there is something not working well with your pelvic floor, your therapist will partner with you to help treat it and get you feeling better. You will be equipped with a home program and behavioral modifications to ease the bladder symptoms so you can go back to a pain and symptom-free life!
