A 66-year-old female patient visited another hospital complaining of frequent urination. Computed tomography scan revealed a 3 cm urethral stone, and she was referred to our hospital for surgery. The patient had a history of tension-free vaginal tape (TVT) surgery for stress urinary incontinence approximately 15 years ago. When transurethral lithotripsy was initiated, the lower end of the stone was found near the external urethral meatus, and an attempt to push it into the bladder was unsuccessful. When fragmentation of the stone was performed using a Ho-YAG laser, exposure of the mesh, presumably from the previous TVT surgery, was detected. A loop electrocautery was used to remove as much of the exposed mesh and the stone as possible. Cystoscopic observation was not possible, but no stone recurrence or mesh-related complications have been noted six months after the surgery. Cases of urethral stones caused by mesh exposure in the urethra after TVT are rare, and we report this case together with a literature review.
