Erosion of a fascial sling into the urethra.

When synthetic materials are used for the construction of pubovaginal slings, urethral erosions may occur. This complication has not been reported with fascial slings. We present a case of a 34-year-old woman who underwent a pubovaginal sling procedure using rectus fascia. After 10 weeks of urinary retention, urethroscopy identified an erosion of the sling at the midurethra. Surgical revision restored normal voiding without recurrent stress incontinence. Although urethral erosions have been reported with synthetic suburethral slings, this case suggests that erosions can also occur with fascial slings. Careful positioning and minimal tension on the sling arms may minimize this risk.
