In a 44-year-old patient with bilateral double‑J ureteral stents who has painful stents and a urinalysis showing more than 250 white blood cells, what is the appropriate management?

Management of Bilateral JJ Stents with Pyuria and Pain

This patient requires urgent urine culture with antimicrobial susceptibility testing, immediate empiric antibiotic therapy, and consideration for stent removal or exchange once infection is controlled, as bilateral stents with significant pyuria (>250 WBC) represent a complicated urinary tract infection with high risk of progression to urosepsis.

Immediate Assessment and Classification

This 44-year-old male has a complicated UTI by definition—the presence of bilateral ureteral stents constitutes a urological abnormality that automatically excludes this from being uncomplicated 1. The marked pyuria (>250 WBC/hpf) with painful stents suggests active infection, potentially stent-associated.

Critical First Steps

1. Obtain urine culture and antimicrobial susceptibility testing immediately before starting antibiotics 1
2. Assess for systemic signs of infection: fever >38°C, chills, hemodynamic instability, or signs of sepsis
3. Evaluate stent dwell time: Prolonged indwelling significantly increases risk of encrustation, biofilm formation, and infectious complications 2

Antibiotic Management

Start empiric broad-spectrum antibiotics immediately while awaiting culture results, as this is a complicated UTI with potential for rapid progression 1:

• If outpatient management appropriate (no sepsis, tolerating oral intake): Fluoroquinolone or oral cephalosporin
• If requiring hospitalization (systemic symptoms, sepsis concern): IV fluoroquinolone, aminoglycoside (±ampicillin), or extended-spectrum cephalosporin/penicillin 1
• Tailor therapy based on culture results and local resistance patterns

Important Caveat

Avoid nitrofurantoin, fosfomycin, and pivmecillinam for upper tract infections—insufficient efficacy data in this setting 1.

Stent Management Strategy

The bilateral stents are likely contributing to both the infection and pain symptoms. Stent-related complications occur in approximately one-third of patients, with lower urinary tract symptoms (38.9%), pain (16.1%), and infectious complications (11.1%) being most common 2.

Decision Algorithm for Stent Intervention:

Option 1: Early stent removal (preferred if feasible)

• If infection controlled within 7 days and original indication for stents resolved
• Evidence shows 7-day stent indwelling effectively manages infection in ureteral calculi cases and allows safe subsequent intervention 3
• Reduces ongoing nidus for infection and eliminates pain source

Option 2: Stent exchange

• If ongoing indication for drainage exists (obstruction, stones, surgical healing)
• Remove infected stents and replace with new ones after infection control
• Critical: Prolonged dwell time markedly increases encrustation risk and morbidity 2

Option 3: Temporary percutaneous nephrostomy

• Consider if stents cannot be safely removed during active infection
• Particularly relevant in elderly or diabetic patients where ureteral manipulation during infection carries perforation risk 4

Pain Management

While treating the infection, address stent-related pain:

• Alpha-blockers (e.g., tamsulosin): Effective for stent-related symptoms 5
• NSAIDs: Well-tolerated and reduce symptoms 5
• Anticholinergics: Can be added, especially for bladder irritation symptoms 5
• Consider combination therapy based on symptom severity

Imaging Considerations

Obtain upper tract imaging (ultrasound or CT) if:

• Patient remains febrile after 72 hours of appropriate antibiotics 1
• Clinical deterioration occurs
• Concern for obstruction, abscess formation, or stent malposition
• Need to assess for underlying stone disease or encrustation

Critical Pitfall

Periureteral abscess formation is a rare but serious complication of stent placement, particularly in diabetic patients with chronic infection 4. If abscess develops, percutaneous drainage is essential—antibiotics alone have limited efficacy.

Follow-up and Prevention

Once acute infection resolves:

• Remove stents as soon as clinically appropriate to prevent encrustation and recurrent infection
• If stents must remain, establish structured follow-up system to prevent "forgotten stent" complications 2, 6
• Stent dwell time ranging from 7 days to months dramatically increases complication rates 2
• Patient education regarding stent removal timeline is essential

The combination of bilateral stents, significant pyuria, and pain creates substantial morbidity risk—aggressive infection management with early consideration for stent removal optimizes outcomes and quality of life.
