What is the next step in managing a 93-year-old patient with persistent hematuria (blood in the urine) after treatment for a urinary tract infection (UTI)?

Management of Persistent Hematuria in a 93-Year-Old Patient After UTI Treatment

For a 93-year-old patient with persistent hematuria after UTI treatment, a complete urologic evaluation is necessary, including upper tract imaging and cystoscopy to rule out urinary tract malignancy, which has significant mortality implications. 1

Risk Stratification and Initial Approach

• This patient falls into the "high risk" category for urologic malignancy due to age >60 years and history of gross hematuria 1
• Persistent hematuria after successful UTI treatment requires further evaluation as UTI-related hematuria should resolve with appropriate antibiotic therapy 1
• In elderly patients, hematuria warrants thorough investigation as the risk of malignancy with gross hematuria exceeds 10% 2

Recommended Diagnostic Algorithm

1. Repeat urinalysis and urine culture:

   • Confirm resolution of UTI and persistence of hematuria 1
   • Assess for dysmorphic RBCs or red cell casts which would suggest glomerular disease 1

2. Laboratory evaluation:

   • Check renal function (serum creatinine) 1
   • Assess for proteinuria which may indicate renal parenchymal disease 1

3. Upper tract imaging:

   • Renal ultrasound as initial imaging modality due to patient's advanced age and to avoid contrast and radiation exposure 1
   • If ultrasound is negative but hematuria persists, consider CT urography (CTU) for more detailed evaluation of the collecting system and ureters 1

4. Urology referral:

   • Indicated for all patients with gross hematuria or persistent microscopic hematuria after UTI treatment 1, 3
   • Cystoscopy should be performed to evaluate the bladder and urethra 1

Special Considerations for Elderly Patients

• In patients >80 years, atypical presentations of urinary tract pathology are common, including altered mental status, functional decline, or falls 1
• Macroscopic hematuria in elderly patients requires evaluation regardless of anticoagulant use 1
• The diagnostic approach should consider the patient's overall health status and life expectancy, but advanced age alone should not preclude thorough evaluation 1, 4

Common Pitfalls to Avoid

• Assuming persistent hematuria is still related to the treated UTI without further evaluation 1, 5
• Failing to refer to urology for cystoscopy, which is essential for ruling out bladder malignancy 1, 3
• Overlooking the possibility of upper tract urothelial carcinoma, which requires specific imaging protocols 1
• Dismissing hematuria in elderly patients as "expected" due to age or comorbidities 4, 5

Follow-up Recommendations

• If initial evaluation is negative, engage in shared decision-making regarding additional testing based on risk factors and patient preferences 1
• For patients with a prior negative evaluation who develop recurrent hematuria, further evaluation is recommended 1
• Even with a negative workup, guidelines recommend semi-annual follow-up for up to 3 years 6
