Pyelonephritis is a type of urinary tract infection where one or both kidneys become infected. Signs and symptoms of pyelonephritis can include:

1. Urgency: This refers to a sudden, compelling urge to urinate. It's often one of the first signs of a urinary tract infection.

2. Occasional Hematuria: Hematuria is the presence of blood in urine. It's not always visible to the naked eye and may require a urine test to detect. Occasional hematuria can be a sign of a kidney infection.

3. Flank Pain: This is pain on one or both sides of the lower back, where the kidneys are located. The pain can be quite severe and is often a key symptom of pyelonephritis.

4. Frequency: This refers to the need to urinate more often than usual. It's a common symptom of urinary tract infections, including pyelonephritis.

If you experience any of these symptoms, it's important to seek medical attention as soon as possible. Pyelonephritis can be serious if not treated promptly.
