Midurethral sling infectious complications: A systematic review.

BACKGROUND

The French Health Authority (Haute Autorité de santé) and French scientific societies (Collège national des gynécologues et obstétriciens français) recommend the use of midurethral slings as the surgical treatment of choice for stress incontinence due to urethral hypermobility and failure of hygienic diet and pelvic rehabilitation. Within a year of implantation, almost 90% of patients no longer experience stress urinary incontinence. Despite their recognized efficacy, retropubic and/or trans-obturator midurethral sling can expose patients to potentially severe infectious complications.

METHODS

A comprehensive literature review using Pubmed, Medline, Embase and Cochrane: "stress urinary incontinence", and/or the following keywords "complications", "infections", "abscess", "prosthetic exposures", "fistula", "erosion", "cellulitis", "fasciitis" in association with the keywords "midurethral slings", "suburethral sling", "tension free vaginal tape" and "trans-obturator tape. In the 330 articles, 61 really dealt with infectious complications following the implantation of synthetic midurethral slings in women.

RESULTS

Preoperative urinalysis and intraoperative antibiotic prophylaxis were rarely reported (n=1 and n=11, respectively). We recorded thirty-six cases of abscess, twenty-one cases of cellulitis, sixteen cases of fistula and forty-one cases of prosthetic exposure. In 95.5% of cases, patients were treated with broad-spectrum antibiotics. Total explantation of the prosthesis was performed in 56% of patients at the initial management, with two-stage explantation performed in 23% of cases, partial explantation was carried out in 12% of cases, and the prosthesis was left in place in 9% of cases. No deaths were recorded.

CONCLUSION

To limit the risk of urinary tract infections and potential prosthetic infections, a prophylactic approach should be adopted by performing a preoperative urinalysis and administering intraoperative antibiotic prophylaxis should be discussed. In the event of prosthetic and/or surgical site infection, broad-spectrum probabilistic antibiotic therapy should be initiated as early as possible until targeted antibiotic therapy. Total explantation of the prosthesis appears to be the most appropriate surgical strategy.
