The most likely cause is a lower urinary tract infection (acute cystitis), because painful urination is typical. However, dribbling can also mean incomplete bladder emptying or urinary retention, which needs prompt assessment in a 68-year-old. A UTI can coexist with retention.
Best next step: same-day medical assessment, ideally today. The clinician should check:
- Urine dipstick and urine culture before antibiotics, if possible
- Post-void residual bladder scan to see whether urine is being retained
- Kidney function and medication review when indicated
- Examination for pelvic organ prolapse, vaginal atrophy, stone, or obstruction
Treatment depends on those results. If uncomplicated cystitis is confirmed, a clinician may prescribe a
short, culture-guided oral antibiotic, selected for local resistance patterns, allergies, kidney function, and other medicines. Do not start leftover antibiotics or choose an antibiotic without evaluation. The
NICE lower-UTI guidance supports antibiotic treatment when appropriate and reassessment if symptoms worsen or do not improve.
For comfort while awaiting assessment: drink normal amounts of water, avoid alcohol/caffeine if they worsen symptoms, and use paracetamol/acetaminophen if normally safe for her. Avoid excessive fluids if she has heart or kidney failure.
Go to urgent care/emergency now if she cannot pass urine at all, has lower abdominal swelling or severe pain, fever/chills, flank/back pain, vomiting, confusion, marked weakness, or visible blood in urine. These may indicate urinary retention, kidney infection, or severe infection.
