Differential Diagnosis for UTI in Females
- Single most likely diagnosis
- Uncomplicated cystitis: This is the most common diagnosis for a female presenting with symptoms of a UTI, such as dysuria, frequency, and urgency. The majority of cases are caused by Escherichia coli.
- Other Likely diagnoses
- Pyelonephritis: An infection of the upper urinary tract, which can present with symptoms such as flank pain, fever, and chills, in addition to the typical symptoms of a UTI.
- Urethritis: Inflammation of the urethra, which can be caused by infection or other factors, and may present with symptoms such as dysuria and discharge.
- Interstitial cystitis: A chronic condition characterized by bladder pressure, bladder pain, and sometimes pelvic pain, which can be mistaken for a UTI.
- Do Not Miss (ddxs that may not be likely, but would be deadly if missed.)
- Sepsis: A life-threatening condition that can occur if a UTI is left untreated or if the infection spreads to the bloodstream.
- Kidney stones: While not typically life-threatening, kidney stones can cause severe pain and may be associated with a UTI.
- Tuberculosis of the urinary tract: A rare but serious condition that can present with symptoms similar to a UTI.
- Rare diagnoses
- Emphysematous pyelonephritis: A rare and serious condition characterized by gas formation in the kidney, which can be life-threatening if not promptly treated.
- Xanthogranulomatous pyelonephritis: A rare form of chronic pyelonephritis characterized by the destruction of kidney tissue and the formation of granulomas.
- Malacoplakia: A rare condition characterized by the formation of plaques in the urinary tract, which can be associated with a UTI.
