When I Pee: A Case Study in Differential Diagnosis of
Dysuria in a 28-Year-Old Female
,Abstract
Brianna Gill is a 28-year-old female who presents to an outpatient primary care clinic with a
chief complaint of "pain when I pee." She reports a 48-hour history of acute-onset dysuria,
urinary frequency, urgency, and suprapubic discomfort. She is afebrile and denies flank pain,
nausea, vomiting, or vaginal discharge. Her history is notable for inconsistent condom use
with one male partner. Urinalysis reveals pyuria, positive leukocyte esterase, and positive
nitrites. Serum β-hCG pregnancy test is negative. The clinical presentation is consistent
with acute uncomplicated lower urinary tract infection (cystitis) . Differential diagnoses
include acute pyelonephritis, sexually transmitted urethritis/cervicitis (Chlamydia
trachomatis, Neisseria gonorrhoeae), vulvovaginitis (candidiasis, bacterial vaginosis,
trichomoniasis), nephrolithiasis, and pelvic inflammatory disease. Treatment is initiated with
nitrofurantoin 100 mg PO BID for 5 days. Patient education focuses on medication
adherence, symptom management, prevention strategies, and return precautions. This case
study demonstrates the importance of a thorough history, including a comprehensive sexual
history, to differentiate UTI from STI co-infections in sexually active young women.
