Should I Go to the ER for a Kidney Stone?

Go to the emergency room for kidney stone symptoms when the pain is severe or rapidly worsening, or when it comes with fever or chills, persistent vomiting, blood in the urine, or an inability to urinate. These can signal a stone causing a blockage or infection, which may require urgent evaluation. If symptoms are severe or you feel faint, seek emergency care right away.

Many smaller kidney stones pass on their own with time and fluids, but larger stones can block the urinary tract and cause intense pain and complications. Because a blocked stone combined with infection can become serious quickly, emergency evaluation is the safer choice when symptoms are severe. Montrose Emergency Room can assess your symptoms and perform imaging and laboratory testing when medically appropriate.

Know the Warning Signs

Kidney Stone Symptoms That May Require Emergency Care

Kidney stone symptoms range from mild to severe. The following may warrant emergency evaluation. This list is educational and does not replace an individual medical evaluation.

  • Severe flank or side pain (back, below the ribs)
  • Severe abdominal or groin pain
  • Pain that comes in waves or keeps worsening
  • Persistent vomiting or nausea
  • Fever or chills with the pain
  • Blood in the urine
  • Pain or burning when urinating
  • Inability to urinate or very little urine
  • Cloudy or foul-smelling urine

Fever and chills with flank pain can signal a serious infection. Seek emergency care promptly, and call 911 if you feel faint, confused or severely ill.

Other Possible Causes

Conditions That Can Feel Like a Kidney Stone

Severe flank, side or abdominal pain is not always a kidney stone. Similar symptoms can be caused by urinary tract or kidney infections, gallbladder problems, appendicitis, muscle injury and other conditions. Because some of these need urgent treatment, an in-person emergency evaluation helps determine the cause. The information here is general and does not diagnose any individual condition.

On-Site Diagnostics

Kidney Stone Testing at Montrose ER

When medically appropriate, the care team may use on-site imaging and laboratory testing to evaluate kidney stone symptoms in a single visit.

CT Scan

CT imaging may help evaluate certain head, chest and abdominal emergencies when ordered by the physician.

Digital X-Ray

X-rays help assess possible fractures, certain chest conditions and other injuries.

Ultrasound

Ultrasound may be used for selected abdominal, pelvic and other evaluations when clinically appropriate.

On-Site Laboratory

Lab testing supports evaluation of infection, dehydration, cardiac concerns and other conditions.

EKG & Cardiac Testing

An EKG and related testing may be used for chest pain, palpitations or other heart-related symptoms.

Testing is selected based on your symptoms, examination and the physician's assessment.

Evaluation for suspected kidney stones commonly includes a urinalysis and, when appropriate, CT imaging or ultrasound to help identify a stone and any blockage.
