Common Symptoms
Urinary Symptoms
Most urinary symptoms in outpatient practice are uncomplicated cystitis, but the job is spotting pyelonephritis, urinary retention, and urosepsis — and not treating asymptomatic bacteriuria, especially in older adults. This page covers the can't-miss diagnoses (pyelonephritis, urosepsis, acute urinary retention, obstructing kidney stone with infection, STI mimicking UTI, pregnancy-related complications, prostatitis), red flags including fever, rigors, flank/CVA pain, hemodynamic instability, immunocompromise, the minimum safe first-pass workup (UA with reflex culture, post-void residual when retention suspected, pregnancy test, BMP if pyelo concerning), evidence-based antibiotic selection, avoiding overtreatment of asymptomatic bacteriuria, escalation criteria, documentation, and return precautions. Written for NPs, PAs, and MDs in outpatient practice.

Urinary Symptoms
Why this symptom matters
USPSTF and IDSA are clear: do not screen for or treat asymptomatic bacteriuria in nonpregnant adults. A positive UA without urinary symptoms is rarely a UTI in an older adult — and treating it causes more harm than benefit.
What must I not miss first?
- Pyelonephritis
- Urosepsis
- Urinary obstruction / retention with hydronephrosis
- Kidney stones with infection
- Pregnancy-related UTI (treat differently)
- Prostatitis
- Cancer — gross hematuria in older adult is bladder cancer until proven otherwise
Red flags — escalate or work up urgently
- Fever, rigors, flank pain, or hemodynamic change (pyelo / sepsis)
- Inability to void / palpable bladder (retention)
- Pregnancy
- Anatomic GU abnormality, indwelling catheter, recent instrumentation
- Immunocompromise, transplant, or diabetes with poor control
- Gross hematuria — especially painless in older adult
- Recurrent UTI in male
Minimum safe first-pass workup
- Confirm true urinary symptoms (dysuria, frequency, urgency, suprapubic pain)
- UA ± culture only when symptoms support a UTI or there's another clinical indication
- Pregnancy test in reproductive-age women
- Bladder scan or post-void residual if retention suspected
- CMP if pyelo or obstruction concern
- Avoid reflex urine testing in nonpregnant older adults without symptoms
What can usually be managed outpatient
- Uncomplicated cystitis in nonpregnant adult — short course of guideline-concordant antibiotic
- Mild prostatitis with normal vitals
- Stable BPH with LUTS and no retention
- Functional incontinence with benign workup
When to escalate to ED / higher level of care
- Pyelonephritis with vomiting, hemodynamic change, pregnancy, or inability to tolerate PO antibiotics
- Urosepsis
- Urinary retention or obstruction with hydronephrosis
- Stone with infection
- Gross hematuria with clots / inability to void
What to document when the diagnosis is still uncertain
- Specific symptoms (or their absence) — don't say UTI without them
- Pregnancy status
- Why UA / culture was or was not obtained
- Antibiotic chosen and rationale; allergy/resistance considered
- Hematuria workup plan if applicable
Safety-net & return precautions to give
- Return or go to ED for fever, chills, flank/back pain, vomiting, inability to urinate, or feeling much sicker.
- Return for blood in urine that won't clear or pregnancy concerns.
- Follow up in [X days] if not improving on antibiotics.
