A novel technique for complete laparoscopic excision of a transobturator sling with lower urinary tract mesh erosion.

introduction and hypothesisTo demonstrate a novel technique for complete laparoscopic removal of a transobturator sling for mesh erosion involving a large area of the urethra and bladder neck, without the need for concomitant vaginal dissection.

methodA 56-year-old woman had a transobturator sling inserted for stress urinary incontinence (SUI) in 2009. In 2017, 8 years following surgery, she experienced groin pain, exacerbated by exercise, and developed recurrent urinary tract infections with dysuria and urethral pain. A cystoscopy demonstrated mesh erosion from the midurethra to bladder neck with a 2-cm calculus formed around the mesh. After careful counselling and discussion at a multi-disciplinary meeting, a decision was made to proceed with laparoscopy with a view to remove the mesh completely. The mesh was removed from the points of erosion into the urethra through a total laparoscopic procedure. The patient made a good recovery with no ongoing pain or voiding difficulties.

conclusionCombined approaches for complete excision of transobturator slings, including bilateral inguinal dissection, are relatively morbid with prolonged recovery time and in most centres will require involvement of plastic surgeons. The laparoscopic approach not only allows for the mesh to be removed in total (including the intramural portion of the mesh), but also provides magnified views compared with open surgery and thus allows for better identification of planes and dissection. It also has the added benefit of avoiding vaginal incisions and therefore reducing the risk of fistula formation between the urethra/bladder and vagina.
