A urinary tract infection is usually a nuisance rather than an emergency. Most are treated in a clinic and settle within days, and we will tell you plainly when that is the right route for you.
What changes the picture is a fever, back pain, or vomiting alongside it. Those suggest the infection has climbed to the kidneys, and from there it can reach the bloodstream. That version needs testing and treatment the same day, which is what we are open around the clock for.
Go to the ER for a UTI when it comes with a fever or chills, pain in your back or side, nausea or vomiting, confusion in an older adult, or blood in the urine. Any of those suggests the infection is no longer confined to the bladder.
A straightforward bladder infection causes burning, urgency, and needing to go constantly while producing very little. Unpleasant, but not dangerous, and a clinic handles it well. The signs below are different in kind, not just degree.
The fever is the line worth memorizing. A bladder infection does not usually cause one. A kidney infection almost always does.
Fever, chills, and a deep ache in the back or side are the classic signs that an infection has climbed from the bladder to a kidney. Nausea and vomiting often join them, and people frequently describe feeling genuinely unwell in a way a bladder infection never caused.
The location of the pain is the most useful clue. Bladder infections hurt low down, at the front, above the pubic bone. A kidney infection hurts higher and further back, in the flank just below the ribs, and it is often worse when that area is tapped.
It rarely happens all at once. Most people describe two or three days of ordinary urinary symptoms, and then a distinct turn: the shivering starts, the back begins to ache, and the whole illness changes character within a few hours.
That turn is the moment to come in. A kidney infection treated the same day usually resolves without incident. Left another day or two, it can seed the bloodstream, and that version is considerably harder to treat.
For most healthy adults a UTI stays in the bladder and clears without drama. These groups need a lower threshold, because the infection spreads more readily or announces itself less clearly.
Older adults. Confusion is frequently the first and sometimes the only sign. A relative who has become suddenly muddled, with no burning and no complaint at all, may well have a urinary infection. It is one of the most commonly missed diagnoses in this age group.
Anyone pregnant. Urinary infections in pregnancy spread to the kidneys far more readily and carry risks for the pregnancy itself. Any symptoms deserve assessment, however mild they seem.
People with diabetes. Higher blood sugar makes the urinary tract more hospitable to bacteria, and the immune response is often less effective. Infections progress faster and more quietly.
Men. UTIs are far less common in men, and a man with urinary symptoms is more likely to have an underlying cause that needs finding rather than a simple infection.
Anyone with a catheter, a stent, or a history of stones. Anything foreign or obstructing in the urinary tract gives bacteria somewhere to establish. A stone with an infection behind it is a genuine emergency.
People with repeated infections. Three or more in a year is worth investigating for a cause rather than treating each one in isolation.
If one of these describes you, do not wait to see whether it settles on its own. Being assessed early is what keeps a simple infection simple.
One item in the right-hand column will genuinely slow down your diagnosis, and it is the thing most people do first.
| Do this | Never do this |
|---|---|
| Come in able to provide a urine sample | Empty your bladder right before arriving |
| Note when symptoms started and how they changed | Start leftover treatment from a previous infection |
| Keep drinking water steadily | Rely on cranberry products to treat an infection |
| Check and record your temperature | Dismiss chills as feeling cold |
| Mention any past kidney infections or stones | Leave out a catheter or recent procedure |
| Come in the same day if a fever appears | Wait to see if the back pain settles overnight |
That first row matters more than it sounds. We need a urine sample to diagnose anything, and someone who emptied their bladder in the parking lot may wait an hour before they can provide one. Hold on if you comfortably can.
The second row is worth taking seriously as well. Starting leftover treatment from a previous infection can make the urine culture harder to interpret, which means less certainty about what is actually growing and what will work against it.
Your physician tests your urine on site, checks bloodwork for signs the infection has spread, images the kidneys if a blockage is suspected, starts treatment without waiting for the culture, and arranges the follow-up that matters two days later.
A rapid analysis confirms infection within minutes, and a culture is sent to identify exactly what is growing.
Blood testing shows whether the infection has moved beyond the urinary tract and how the kidneys are coping.
CT or ultrasound where a stone may be trapping infection behind it, which changes the treatment entirely.
Antibiotic treatment begins during the visit rather than waiting two days for the culture to finish growing.
Vomiting and fever leave people dry. Fluids through a vein help both the dehydration and the kidneys.
Results arrive two to three days later. If the treatment needs changing, we contact you rather than leaving it to chance.
A simple bladder infection belongs in urgent care or with your own doctor, and it will cost you less there. An emergency room is for a UTI with a fever, back pain, vomiting, confusion, or one that has not improved after treatment has already started.
We would rather say that plainly than take a visit that did not need to happen. Burning, urgency, and going frequently without any fever is the most common presentation there is, and a clinic handles it perfectly well.
What changes the answer is the possibility that the kidneys are involved, because that needs bloodwork, imaging, and sometimes treatment given through a vein. Clinics generally cannot do those things, and being sent onward costs you a second visit and a second bill.
The other situation worth naming is timing. Urinary infections have a habit of turning at two in the morning, and a fever with back pain that appears on a Saturday night should not wait until Monday. We are open every hour for that reason.
If you are genuinely unsure, call us on 817-973-7406 and describe what is happening. We will tell you honestly whether this is a clinic problem or ours.
Waiting two days for results while a kidney infection progresses is not an option. We treat now and adjust later.
It is one of the most missed presentations in medicine, and one of the most treatable once found.
Infection sitting behind a stone will not clear with treatment alone. Imaging finds it during the visit.
Results land days after you leave. If what is growing needs different treatment, you hear from us.
A UTI visit is billed as an emergency visit plus the urine and blood testing your physician orders, and imaging if a blockage is suspected. We accept most major private insurance plans and file the claim for you.
UTIs carry a billing detail that arrives after you have gone home, so it is worth flagging now. The urine culture is sent to a laboratory and finishes growing two to three days later, which means a separate charge appearing on a statement well after the visit. Patients often read that as a duplicate. It is not: the culture is what confirms whether the treatment you were given is actually the right one for the bacteria you have.
Being straightforward about value: for a simple bladder infection with no fever, a clinic costs less and does the job. This page exists for the version with a fever and back pain, where bloodwork, imaging and treatment through a vein may all be needed and a clinic would send you here anyway.

Arlington ER serves Arlington, Texas from 1607 S. Bowen Rd., on the west side of Bowen just south of Pioneer Parkway. Parking is directly outside the entrance, and restrooms are close by, which matters more than usual with this particular problem.
We are minutes from central Arlington and the Parks Mall, and a short drive from Dalworthington Gardens, Kennedale, Grand Prairie, and Mansfield. From I-20, exit at Bowen Road and head north. From Highway 303 or Pioneer Parkway, turn south onto Bowen and we are on your right. Our Contact Us page has anything else you need.
We are open every hour of every day, holidays included, with no appointment or referral required.
Burning and urgency can wait for a clinic. Burning with chills and an ache in your back cannot. If the illness has changed character in the last few hours, walk in and let us test it properly tonight.
Usually one to two hours for a straightforward assessment. Longer if bloodwork suggests the kidneys are involved, or if imaging is needed to look for a blockage.
Because bacteria have to grow before they can be identified and tested. That growth takes time and cannot be rushed, which is exactly why treatment starts on the day rather than waiting.
Some very mild bladder infections do settle on their own. It is not a reliable outcome, and the risk of waiting is that the infection travels upward to the kidneys instead.
Most people feel noticeably better within a day or two. If you are no better after 48 hours, or getting worse at any point, come back rather than waiting out the full course.
The evidence suggests a modest role in reducing how often infections recur in some people. There is no evidence it treats an infection you already have, so it is not a substitute for being seen.
Yes, and in young children the signs are often vague: fever with no obvious source, irritability, poor feeding, or a change in toilet habits. A child with an unexplained fever deserves a urine test.
Three or more in a year deserves investigation rather than repeated treatment. There is often an underlying reason worth finding, and that work belongs with a urologist rather than an emergency room.
No. We collect it here using a sterile container, which keeps the sample clean enough for the culture to mean something. Just try not to empty your bladder immediately before arriving.
