Kidney Infection & UTI Emergency Treatment in Irving, TX

A UTI with fever, chills, back or side pain, or vomiting can mean the infection has reached your kidneys. Walk in any hour. A physician is on site 24/7, with urine and blood tests, CT and ultrasound, and IV antibiotics when you need them.

When Does a UTI Need the ER?

MedlinePlus says to contact a provider right away if you have signs of a possible kidney infection. Come in any hour if you have a UTI and any of these.

Fever or Chills

Fever above 101°F (38.3°C), chills, shaking or night sweats can mean the infection has spread to your kidneys.

Back, Side or Groin Pain

Pain in your back, your side below the ribs, or your groin is a kidney infection sign.

Vomiting

If you cannot keep fluids or antibiotic pills down, you may need them through an IV.

Confusion in an Older Adult

In older people, confusion or other mental changes are often the only sign of a UTI.

Pregnant With Fever

Bladder infections in pregnancy are more likely to spread to the kidneys. Come in if you have a fever or feel ill.

Baby Under 3 Months With Fever

The CDC says a baby this young with a fever of 100.4°F (38°C) or higher needs care right away.

Not Better on Antibiotics

Symptoms that get worse, do not improve after starting antibiotics, or come back soon after treatment need a recheck.

Signs of Sepsis

Clammy skin, a racing heart, fast breathing, confusion or extreme pain with an infection is an emergency.

Is It a Simple UTI or a Kidney Infection?

Most UTIs start in the bladder. A bladder infection can cause burning when you urinate, a strong need to go often, cloudy or bloody urine, and pressure in your lower belly. MedlinePlus says a simple bladder infection is treated with antibiotics for 1 to 5 days in women or 7 to 14 days in men. Urgent care or your own doctor can usually handle that.

A kidney infection is less common but more serious, according to the CDC. It usually starts in the bladder and moves up to one or both kidneys. Fever, chills, back or side pain, nausea and vomiting are the signs to watch. NIDDK says to seek care right away for kidney infection symptoms, because a kidney infection could lead to sepsis.

Urinalysis for Kidney & Urinary Tract Health

What Happens When You Come In

Texas requires a physician on site whenever a freestanding emergency room is open. Ours is open 24/7, so a physician is always here.

1

Exam and History

Tell us your symptoms, your medicines, and whether you might be pregnant. That can change which medicines and scans are right for you.

2

Urine and Blood Tests

A urinalysis looks for white blood cells, blood and bacteria. Blood tests check for serious infection and how well your kidneys work.

3

Urine Culture

A culture identifies the bacteria and the best antibiotic. It takes a few days, so we call you with the result.

4

CT or Ultrasound if Needed

Imaging on site can check for a kidney stone, a blockage or a pocket of pus around the kidney. Ultrasound uses no radiation.

5

Treatment

Antibiotics by mouth, through an IV, or both. IV fluids and medicine for pain and nausea when you need them.

6

Home or Hospital

If you can take pills and drink fluids, you may go home on antibiotics. If you need a hospital stay, we arrange the transfer.

Who Is More Likely to Have a Serious Kidney Infection?

NIDDK says most kidney infections do not lead to complications when found early and treated properly. The chance of a complication is slightly greater for these groups.

Older or Frail Adults

Weakened strength or other problems of aging raise the risk. Confusion may be the only sign.

Pregnancy

Kidney infections are common during pregnancy. A fever or feeling ill during pregnancy may need hospital care.

Diabetes, Kidney Disease or Sickle Cell Disease

These conditions make complications from a kidney infection more likely.

Kidney Stones or a Blockage

A stone or an enlarged prostate can block urine and cause a kidney infection. The blockage may need its own treatment.

Weak Immune System or Transplant

A weakened immune system or an organ transplant makes it harder to fight the infection.

Men and Repeat Infections

Being male or having had repeat kidney infections also raises the chance of a complication.

Kidney Infection and UTI Questions, Answered

Not always. A simple bladder infection is usually treated with antibiotic pills from urgent care or your own doctor. MedlinePlus says to contact a provider right away for signs of a possible kidney infection, such as back or side pain, chills, fever or vomiting. With those signs, come in any hour.

It can, though it is uncommon. NIDDK says a kidney infection could lead to sepsis, which can be life threatening. The CDC lists the urinary tract as one of the places sepsis most often starts. Watch for confusion, a racing heart, fast breathing, clammy skin or extreme pain. Call 911 if symptoms are life threatening.

We start with a urinalysis, which looks for white blood cells, blood and bacteria in your urine. Blood tests, such as a complete blood count and a blood culture, check for serious infection. A urine culture shows which antibiotic will work. CT or ultrasound can look for a stone, a blockage or an abscess.

Not always. NIDDK says you may take antibiotics by mouth, through an IV line, or both. IV antibiotics and fluids are more likely if you are very sick, are vomiting, or cannot drink enough. Your antibiotic may be adjusted once the urine culture result comes back.

Tell us right away. NIDDK says bladder infections during pregnancy are more likely to spread to the kidneys. MedlinePlus lists being pregnant with a fever or feeling ill as a reason for hospital care. It also says to tell your provider if you might be pregnant before taking antibiotics. Ultrasound can check the kidneys without radiation.

Yes. We treat children and teens up to age 18. NIDDK says children younger than 2 with a kidney infection may only have a high fever. The CDC says a baby younger than 3 months with a fever of 100.4°F (38°C) or higher needs care right away. Young infants most often need IV antibiotics in a hospital, and we arrange that transfer.

MedlinePlus says bladder infection symptoms most often go away within 24 to 48 hours after treatment begins. A kidney infection may take 1 week or longer. Contact your provider if symptoms get worse, do not improve on antibiotics, or come back shortly after treatment.

Yes. We do not turn anyone away. Texas rules require every freestanding emergency room to give each patient a medical screening, exam and stabilization without regard to ability to pay. Our insurance and billing page explains how billing works.

We arrange your transfer to a hospital. Texas requires every freestanding emergency room to have patient transfer agreements with hospitals. That way a hospital bed can be arranged when you need care we cannot provide here.
