Differential Diagnosis for 14-year-old Female with Possible UTI
- Single Most Likely Diagnosis
- Urinary Tract Infection (UTI): This is the most likely diagnosis given the presentation. UTIs are common in females, especially during adolescence, and symptoms such as dysuria, frequency, and urgency are typical.
- Other Likely Diagnoses
- Vulvovaginitis: This condition, often caused by bacterial or fungal infections, can present with similar symptoms to UTIs, including discomfort and abnormal discharge.
- Sexually Transmitted Infections (STIs): Given the age of the patient, it's essential to consider STIs, such as chlamydia or gonorrhea, which can cause symptoms similar to those of a UTI.
- Overactive Bladder: This condition can cause urinary frequency and urgency without an infection being present.
- Do Not Miss Diagnoses
- Pyelonephritis: An infection of the kidney, which can occur if a UTI moves up the urinary tract. It's crucial to diagnose and treat promptly to prevent long-term kidney damage.
- Sepsis: Although rare, if a UTI or other infection becomes severe, it can lead to sepsis, a life-threatening condition that requires immediate medical attention.
- Appendicitis: While less common, appendicitis can sometimes present with symptoms similar to a UTI, especially if the appendix is located near the bladder.
- Rare Diagnoses
- Interstitial Cystitis: A chronic condition causing bladder pressure, bladder pain, and sometimes pelvic pain. The symptoms can mimic those of a UTI but are more persistent.
- Urethral Diverticulum: A condition where a pouch or pocket forms in the wall of the urethra, which can cause symptoms similar to a UTI, including recurrent infections.
- Bladder or Kidney Stones: Although less common in adolescents, stones can cause severe pain and symptoms similar to a UTI.
