Abstract

Aims: Our aim was to assess the usability of the IUGA/ICS classification system for mesh erosion in a tertiary clinical practice and to determine if assigned classification is associated with patient symptoms, treatment, and outcome.

Methods: We retrospectively identified women who had mesh erosion after prolapse or incontinence surgery. Each erosion was classified using the IUGA/ICS category time site (CTS) system. Associations between classification and presenting symptom (asymptomatic, pain, bleeding, voiding, or defecatory dysfunction, infection, prolapse), treatment type, and outcome were evaluated with chi-squared test, student's t-test, and univariate logistic regression.

Results: We identified 74 subjects with mesh erosion; only 70% were classifiable. Asymptomatic patients (n = 19) (Category A) were more likely to be managed conservatively (P = 0.001). Symptomatic patients (n = 55) (Category B) were more likely to be managed surgically (P = 0.003). Other variables had no association with treatment. No variables were associated with outcome. Presenting symptom was associated with both treatment (P = 0.005) and outcome (P = 0.03). Asymptomatic subjects were more likely to have satisfactory outcome (P = 0.03). Urinary frequency and urgency were highly correlated with surgical management (P = 0.02).

Conclusions: One third of mesh erosions could not be retrospectively coded using the IUGA/ICS classification. The components of the system were not predictive of treatment nor outcome with exception of the Category A (asymptomatic) and Category B (symptomatic). Asymptomatic women with mesh erosion can be successfully managed with conservative measures. Use of a classification system may be enhanced if the system is simplified by limiting the number of variables to those associated with interventions and patient outcome. Neurourol.
