Comprehensive Clinical Guidelines and Best Practices for Ureteral Stent Selection, Placement, Maintenance, Prevention of Complications, and Patient-Centered Care

The successful use of ureteral stents depends not only on the quality of the device but also on appropriate patient selection, meticulous procedural technique, effective postoperative care, and timely follow-up. Even the most advanced stent can fail if it is improperly selected, inserted, monitored, or removed.

Over the years, international urological associations and clinical studies have emphasized evidence-based best practices to minimize complications such as infection, migration, encrustation, obstruction, pain, and forgotten stents. Equally important is the growing emphasis on patient-centered care, where treatment decisions are tailored to each individual’s medical condition, lifestyle, preferences, and expectations.

This chapter presents practical clinical guidelines that healthcare professionals can apply throughout the entire process of ureteral stent management.

Principles of Patient-Centered Care

Modern healthcare extends beyond treating disease. It focuses on understanding the patient’s physical, emotional, psychological, and social needs.

Patient-centered care involves:

• Shared decision-making
• Clear communication
• Respect for patient preferences
• Individualized treatment planning
• Ongoing education
• Continuous follow-up

These principles improve treatment satisfaction and clinical outcomes.

Appropriate Patient Selection

Not every urinary condition requires ureteral stenting.

Before recommending a stent, clinicians should evaluate:

• Severity of obstruction
• Kidney function
• Presence of infection
• Duration of expected treatment
• Previous urinary tract procedures
• Risk of complications
• Patient’s overall health

Careful assessment helps avoid unnecessary procedures.

Comprehensive Medical History

A thorough history should include:

• Previous kidney stones
• Prior ureteral surgeries
• Recurrent urinary tract infections
• Chronic kidney disease
• Diabetes mellitus
• Bleeding disorders
• Medication history
• Drug allergies
• Pregnancy status
• Previous stent-related complications

These factors influence treatment planning.

Physical Examination

Clinical examination should assess:

• Flank tenderness
• Abdominal pain
• Fever
• Hydration status
• Blood pressure
• Signs of sepsis
• Bladder distension

Abnormal findings may indicate urgent intervention.

Laboratory Evaluation

Routine laboratory investigations often include:

• Complete blood count
• Serum creatinine
• Blood urea nitrogen
• Electrolytes
• Blood glucose
• Urinalysis
• Urine culture

These investigations identify infection and assess kidney function.

Imaging Before Stenting

Appropriate imaging is essential.

Common imaging modalities include:

• Ultrasonography
• Computed tomography (CT)
• Magnetic resonance imaging (MRI)
• Intravenous urography
• Fluoroscopic studies

Imaging helps determine:

• Site of obstruction
• Stone size
• Ureteral anatomy
• Kidney function
• Degree of hydronephrosis

Selecting the Right Stent

Several factors influence stent selection.

These include:

• Material
• Length
• Diameter
• Flexibility
• Surface coating
• Expected indwelling duration
• Cause of obstruction

No single stent is ideal for every patient.

Determining Stent Length

Proper stent length minimizes complications.

A stent that is too short may migrate.

A stent that is too long may cause:

• Bladder irritation
• Increased urinary urgency
• Pain
• Hematuria

Individualized sizing improves comfort.

Choosing Stent Diameter

Diameter influences both drainage and patient symptoms.

Larger diameters may:

• Improve drainage
• Resist compression

However, they may also increase discomfort.

The smallest diameter capable of providing adequate drainage is generally preferred.

Preparing for the Procedure

Proper preparation includes:

• Reviewing imaging
• Confirming indication
• Obtaining informed consent
• Treating active infection
• Administering prophylactic antibiotics when indicated
• Ensuring sterile equipment availability

Careful preparation reduces procedural complications.

Sterile Technique

Strict aseptic technique remains fundamental.

Measures include:

• Surgical hand preparation
• Sterile gloves
• Sterile drapes
• Sterile instruments
• Appropriate antiseptic skin preparation

Maintaining sterility reduces infection risk.

Guidewire Placement

Guidewire insertion is one of the most critical procedural steps.

Proper guidewire placement:

• Maintains ureteral access
• Reduces trauma
• Facilitates stent advancement
• Improves procedural safety

Excessive force should always be avoided.

Confirming Correct Position

Correct placement must be verified before completing the procedure.

Methods include:

• Fluoroscopy
• Endoscopic visualization
• Ultrasound guidance

The proximal coil should rest securely within the renal pelvis.

The distal coil should remain completely inside the bladder.

Immediate Postoperative Care

Following insertion, clinicians should monitor:

• Urine output
• Pain level
• Vital signs
• Hematuria
• Fever
• Difficulty urinating

Most patients recover rapidly after uncomplicated procedures.

Patient Education

Education significantly improves treatment success.

Patients should receive clear information regarding:

• Purpose of the stent
• Expected urinary symptoms
• Importance of hydration
• Medication instructions
• Warning signs
• Planned removal date

Written information is often beneficial.

Expected Symptoms

Patients should understand that mild symptoms are common.

These may include:

• Urinary frequency
• Urgency
• Mild hematuria
• Flank discomfort
• Bladder irritation
• Mild pain during urination

Most symptoms improve gradually.

Warning Signs

Patients should immediately seek medical attention if they develop:

• High fever
• Severe flank pain
• Inability to urinate
• Persistent heavy bleeding
• Severe nausea
• Chills
• Foul-smelling urine

Early recognition prevents serious complications.

Importance of Hydration

Adequate fluid intake remains one of the simplest methods for reducing complications.

Proper hydration:

• Dilutes urine
• Reduces crystal formation
• Flushes bacteria
• Improves drainage
• Decreases blockage

Unless contraindicated, patients should maintain good daily fluid intake.

Infection Prevention

Preventive measures include:

• Appropriate antibiotic use
• Sterile insertion
• Good personal hygiene
• Timely stent removal
• Regular follow-up

Antibiotics should be prescribed according to clinical indications rather than used routinely for prolonged periods.

Monitoring During Indwelling

Patients with long-term stents require regular review.

Monitoring should assess:

• Kidney function
• Urinary symptoms
• Infection
• Stent position
• Degree of encrustation

Regular assessment helps detect complications before they become severe.

Scheduling Stent Removal

Every temporary stent should have a planned removal date.

Healthcare providers should maintain:

• Electronic reminder systems
• Patient notification programs
• Follow-up appointments
• Procedure scheduling

These measures greatly reduce forgotten stents.

Forgotten Stents

Failure to remove a stent may result in:

• Heavy encrustation
• Stone formation
• Obstruction
• Infection
• Stent fracture
• Kidney damage

Forgotten stents often require complex surgical removal.

Managing Long-Term Stents

Patients requiring chronic stenting should undergo:

• Periodic imaging
• Scheduled stent exchange
• Laboratory monitoring
• Assessment of urinary symptoms
• Evaluation of quality of life

Individualized follow-up intervals depend on the type of stent and the patient’s condition.

Managing Special Populations

Certain patient groups require additional consideration.

Elderly Patients

Older adults may have:

• Reduced kidney function
