Single most likely diagnosis:
- Urinary Tract Infection (UTI) - This is a common condition, especially in young women, characterized by dysuria (painful urination), which could be described as feeling like passing glass due to the severe discomfort.
Other Likely diagnoses:
- Kidney Stones - Small stones can cause severe pain and a feeling of discomfort during urination, which might be likened to passing glass.
- Urethritis - Inflammation of the urethra, often due to infection, can cause painful urination.
- Vaginitis - Inflammation of the vagina, which can cause discomfort during urination if the urethra is irritated.
Do Not Miss diagnoses:
- Sexually Transmitted Infections (STIs) - Certain STIs like gonorrhea and chlamydia can cause severe urinary symptoms, including pain during urination.
- Interstitial Cystitis - A condition causing bladder pressure, bladder pain, and sometimes pelvic pain, which could lead to painful urination.
Rare diagnoses:
- Bladder or Urethral Foreign Body - Although rare, the presence of a foreign body in the urinary tract could cause severe pain during urination.
- Sickle Cell Disease or Sickle Cell Trait with associated renal complications - Could potentially cause kidney damage leading to painful urination, though less common in this presentation.
- Certain types of cancer (e.g., bladder or urethral cancer) - Extremely rare in a 17-year-old but should be considered if other diagnoses are ruled out and symptoms persist.
