Abstract

Purpose: To review our 10-year experience with laser excision for urethral mesh erosion (UME) of mid-urethral slings (MUS).

Methods: Following Institutional Review Board approval, the charts of female patients with endoscopic laser excision of UME were retrospectively reviewed. Demographics, clinical presentation, surgical history, pre- and post-operative Urinary Distress Inventory-6 scores and quality of life ratings, operative reports, and outcomes were obtained from electronic medical records. UME cure was defined as no residual mesh on office cystourethroscopy 5-6 months after the final laser excision procedure.

Results: From 2011 to 2021, 23 patients met study criteria; median age was 56 (range 44-79) years. Twenty (87%) had multiple prior urogynecologic procedures. Median time from MUS placement to presentation with UME-related complaints was 5.3 [interquartile range (IQR) 2.3-7.6] years. The most common presenting symptom was recurrent urinary tract infection (rUTI) (n = 10). Median operating time was 49 (IQR 37-80) minutes. Median duration of follow-up was 24 (IQR 12-84) months. Fourteen (61%) required more than 1 laser excision procedure for UME. Although 5 were asymptomatic (22%), new (n = 5) or persistent (n = 8) urinary incontinence was the most common symptom on follow-up (57%).

Conclusion: UME presenting symptoms are highly variable, necessitating a high index of suspicion in patients with a history of MUS, especially in the case of rUTI. Endoscopic laser excision is a minimally invasive, brief, safe, outpatient procedure with a high UME cure rate.
