Differential Diagnosis for Urinary Retention with UTI in an 83-year-old Female
Single Most Likely Diagnosis
- Urinary Tract Infection (UTI) with associated cystitis or pyelonephritis: This is the most likely diagnosis given the symptoms. UTIs are common in elderly females and can cause urinary retention due to inflammation and irritation of the urinary tract.
Other Likely Diagnoses
- Vaginal prolapse or cystocele: Weakened pelvic muscles in elderly women can lead to prolapse, which may cause urinary retention by obstructing the urethra.
- Neurogenic bladder: Age-related neurologic changes or diseases like diabetes can affect bladder function, leading to urinary retention.
- Medication side effects: Certain medications, such as anticholinergics, can cause urinary retention as a side effect.
- Constipation: Severe constipation can put pressure on the urethra, leading to urinary retention.
Do Not Miss Diagnoses
- Kidney stones: Although less common, kidney stones can cause severe pain and urinary retention. Missing this diagnosis could lead to severe complications, including kidney damage.
- Spinal cord compression or cauda equina syndrome: These conditions can cause neurogenic bladder and urinary retention. Early diagnosis is crucial to prevent permanent damage.
- Pelvic malignancy: Cancers such as cervical, uterine, or bladder cancer can cause urinary retention by obstructing the urinary tract.
Rare Diagnoses
- Foreign body in the urinary tract: Although rare, a foreign body in the urinary tract can cause obstruction and urinary retention.
- Urethral stricture or stenosis: Scarring or narrowing of the urethra can cause urinary retention.
- Interstitial cystitis: A chronic condition causing bladder inflammation and urinary retention, although less common in the elderly population.
