Pelvic ultrasound finding of late-onset bladder erosion after transobturator tape for female stress urinary incontinence: A case report

Abstract

Rationale: Mid-urethral sling is a gold-standard procedure for stress urinary incontinence because of its high efficacy and low complication incidence. Moreover, mesh erosion into the bladder is a rare complication. Patient concerns: The 63-year-old patient visited our gynecology clinic with complaints of gross hematuria and was diagnosed with bladder erosion by ultrasound 6 months after transobturator tape procedure. Diagnoses: The 2D ultrasound found the sling in the bladder wall perforation, which can lead to the formation of bladder stones. Meanwhile, 3D ultrasound showed the left side of the sling crossed the bladder mucosa at 5 o'clock. Interventions: The sling and bladder stones were removed by holmium laser. Outcomes: The patient underwent a follow-up pelvic ultrasound at 6 months, which showed no erosion mesh under the bladder mucosa. Lessons: Pelvic ultrasound could accurately evaluate the location and shape of the tape, which is important for a reasonable surgical plan.
