UTI WARNING SIGNS
When Does a UTI Become an Emergency?
A UTI becomes an emergency when the infection may have reached the kidneys or bloodstream. Go to the ER for urinary symptoms with fever or chills, back or side pain, nausea or vomiting, inability to keep down fluids or antibiotics, severe weakness, or confusion—and sooner if you are pregnant, older, or have diabetes or a weakened immune system.
Burning with urination, frequent urges, and cloudy urine without fever usually point to a bladder infection (cystitis), which most people can have treated by their own doctor, a telehealth visit, or an urgent care clinic.
Get emergency care for urinary symptoms with:
- A fever of 100.4°F or higher, or shaking chills
- Pain in the back, side, or flank
- Nausea or vomiting
- Unable to keep down antibiotics or fluids
- Blood in the urine with severe pain
- Unable to urinate
- Confusion or unusual drowsiness
- Symptoms during pregnancy

UTI With Fever? We’re Open 24/7
Emergency evaluation is available day and night at The Heights Emergency Room.
Simple Bladder Infection (Lower UTI)
Most UTIs begin in the bladder and cause local symptoms.
Typical symptoms
- Burning or pain with urination
- A frequent, urgent need to urinate
- Passing small amounts of urine
- Cloudy or strong-smelling urine
- Pressure in the lower abdomen
Without fever or back pain, these symptoms are usually treated outside the ER. Untreated, however, a bladder infection can travel up to the kidneys.
Kidney Infection (Pyelonephritis)
A kidney infection is more serious and can make you feel much sicker.
Signs it may involve the kidneys
- Fever and shaking chills
- Pain in the back, side, or groin
- Nausea and vomiting
- Feeling very weak or ill
- Urinary symptoms that worsen despite treatment
Kidney infections often need prompt antibiotics and sometimes IV fluids, and they can lead to sepsis if untreated.
Blood in the Urine
Pink, red, or cola-colored urine can come from an infection, a kidney stone, or other causes.
Blood in the urine with severe side or back pain may mean a kidney stone; blood with fever may mean a kidney infection. A stone combined with infection is especially urgent, because a blocked, infected kidney can quickly become dangerous. Learn more about abdominal pain emergencies.
Who Should Be Seen Sooner
Some people can become seriously ill from a urinary infection more quickly.
Higher-risk groups
- Pregnant women
- Adults over 65, who may show confusion instead of typical symptoms
- People with diabetes or a weakened immune system
- People with kidney stones or a urinary catheter
- Men with UTI symptoms
- Infants and young children with fever
COMPLICATIONS
Can a Severe Urinary Infection Cause Vomiting or Dehydration?
Yes. Kidney infections commonly cause nausea and vomiting, which can lead to dehydration and make it impossible to keep oral antibiotics down.
If you can’t hold down fluids or your antibiotic, feel dizzy, or are urinating very little, you may need IV fluids and IV antibiotics. See our vomiting and dehydration page. In older adults, a urinary infection with dehydration can also cause sudden confusion.
YOUR ER VISIT
What Happens When You Visit the ER for a Possible Kidney Infection?
The physician reviews your symptoms, checks your temperature, heart rate, and blood pressure, and examines your abdomen and back.
Urine & Blood Tests
Urinalysis and urine culture identify infection; blood tests check kidney function and signs of a more serious infection.
Imaging When Needed
A CT scan or ultrasound may be used if a kidney stone, blockage, or abscess is suspected.
Treatment
Antibiotics, IV fluids, and medication for pain and nausea may be given based on your evaluation.
Many patients with kidney infections are treated and sent home with antibiotics; some need hospital admission, which the team arranges when necessary.
What Can Cause Severe Urinary Symptoms?
Possible causes can include:
Bacterial Infection
Most UTIs are caused by bacteria entering the urinary tract, often E. coli from the bowel.
Kidney Stones
Stones can block urine flow, cause severe pain, and trap infection.
Urinary Blockage
An enlarged prostate, a catheter, or another obstruction can raise infection risk.
Other Conditions
Sexually transmitted infections and some gynecologic conditions can mimic UTI symptoms.
This list is general information, not a diagnosis. Testing for sexually transmitted infections is available when appropriate.
QUICK ANSWERS
UTI & Kidney Infection Questions, Answered
When does a UTI become an emergency?
A UTI becomes an emergency when it may have spread to the kidneys or bloodstream. Warning signs include fever or chills, back or side pain, nausea or vomiting, inability to keep down fluids or antibiotics, confusion, or severe weakness. Pregnant women, older adults, and people with diabetes or weakened immune systems should be evaluated sooner.
Should I go to the ER for a UTI with fever and back pain?
Yes. Urinary symptoms with fever and back or side pain suggest a kidney infection (pyelonephritis), which often needs urine and blood tests, prompt antibiotics, and sometimes IV fluids. Get evaluated the same day, and go right away if you are vomiting, very weak, pregnant, or confused.
Where should I go in Houston for possible kidney infection symptoms?
The Heights Emergency Room at 101 N Loop W #300, Houston, TX 77018, is open 24/7 for possible kidney infections, with on-site urine and blood testing, imaging, and IV fluids and antibiotics when your physician determines they’re needed. Walk in or check in online. Call 911 for confusion or fainting.
Is blood in the urine with severe pain an emergency?
It can be. Blood in the urine with severe back, side, or abdominal pain often comes from a kidney stone, and with fever it may signal an infected, blocked kidney, which is an emergency. Get evaluated promptly, especially if you are vomiting, have a fever, or can’t urinate.
Can a severe urinary infection cause vomiting or dehydration?
Yes. Kidney infections often cause nausea and vomiting, which can lead to dehydration and keep you from holding down oral antibiotics. Dizziness, very little urine, or a racing heart are reasons to seek emergency care, where IV fluids and IV antibiotics can be given when appropriate.
EMERGENCY SAFETY
When Should You Call 911 for a Urinary Infection?
Call 911 if a urinary or kidney infection comes with signs that it may be affecting the whole body.
Call 911 for:
- Confusion or difficulty waking
- Fainting
- Severe shortness of breath
- A racing heart with cold, clammy, or mottled skin
- Very little urine with extreme weakness
- High fever with severe shaking and confusion
- Severe pain with vomiting in pregnancy
- Rapid worsening over a few hours
Paramedics can begin IV fluids and monitoring on the way and alert the emergency team to possible sepsis.
Don’t drive yourself if you feel faint, confused, or very weak.
WHERE TO GO
ER vs Urgent Care for a UTI
Urgent care, telehealth, or your own doctor is usually the right place for a simple bladder infection. An emergency room is better when fever, back pain, vomiting, or other warning signs suggest a kidney infection or a more serious problem.

- Severe breathing difficulty
- Rapid worsening
Go to the ER

FAQ
UTI & Kidney Infection ER — Frequently Asked Questions
Some mild bladder infections improve on their own, but many need antibiotics, and untreated infections can spread to the kidneys. If symptoms last more than a day or two, worsen, or come with fever or back pain, get evaluated.
It varies, but a bladder infection can spread to the kidneys within days, and sometimes faster. Fever, chills, and back or side pain are the signs to watch for.
Not always. Many kidney infections are treated with oral antibiotics. IV antibiotics may be used if you are vomiting, very ill, pregnant, or have signs of a more serious infection.
UTI symptoms during pregnancy should be evaluated promptly, because infections can spread to the kidneys more easily. Fever, back pain, or vomiting during pregnancy need same-day emergency evaluation.
Yes. Older adults may have confusion, weakness, falls, or loss of appetite rather than burning or frequent urination. Sudden confusion in an older adult should be evaluated.
No. The Heights Emergency Room is open 24/7 for walk-ins, and you can check in online before you arrive.
