Clinical application of IUGA/ICS classification system for mesh erosion

Area of Science:

• Urogynecology
• Pelvic reconstructive surgery
• Medical device complications

Background:

• Mesh erosion is a known complication following pelvic reconstructive surgery for prolapse or incontinence.
• Standardized classification systems are crucial for consistent diagnosis, treatment, and outcome assessment.
• The International Urogynecological Association/International Continence Society (IUGA/ICS) classification system was developed to categorize mesh erosion.

Purpose of the Study:

• To evaluate the clinical utility of the IUGA/ICS classification system for mesh erosion in a tertiary care setting.
• To determine if the assigned IUGA/ICS classification correlates with patient symptoms, treatment strategies, and clinical outcomes.

Main Methods:

• A retrospective review of patients with mesh erosion following prolapse or incontinence surgery was conducted.
• Mesh erosions were classified using the IUGA/ICS category time site (CTS) system.
• Statistical analyses (chi-squared test, t-test, logistic regression) assessed associations between classification, symptoms, treatment, and outcomes.

Main Results:

• Of 74 identified mesh erosions, only 70% were classifiable using the IUGA/ICS system.
• Asymptomatic patients (Category A) were more likely to receive conservative management (P=0.001).
• Symptomatic patients (Category B) were more likely to undergo surgical intervention (P=0.003); presenting symptoms were associated with treatment and outcome.

Conclusions:

• The IUGA/ICS classification system demonstrated limited usability, with a significant portion of mesh erosions unclassifiable retrospectively.
• The classification's predictive value for treatment and outcome was minimal, except for distinguishing asymptomatic (Category A) from symptomatic (Category B) cases.
• Simplifying the IUGA/ICS system to focus on variables impacting interventions and patient outcomes could enhance its clinical utility.
