title: Sling transection of urethra: a rare complication.
abstract: Common postoperative complications associated with suburethral sling procedures include voiding disorders and urinary retention, de novo development of detrusor instability, sling graft rejection and, rarely, erosion of the graft into the urethra. The authors present a case of a late postoperative complication of polytetrafluoroethylene graft erosion and partial transection of the urethra, with resultant acute urinary retention. A 50-year-old patient presented with acute urethral outflow obstruction due to sling graft erosion into the urethra nearly 2 years after she underwent a curative sling procedure for recurrent genuine stress incontinence. After relieving the acute urinary retention by inserting a suprapubic catheter under ultrasound guidance, the sling graft was accessed and removed. The urethral defect was repaired successfully. At follow-up 5 months later, the patient was continent subjectively and by urodynamic criteria, with no voiding abnormalities. Although erosion of the sling graft into the urethra and transection of this structure is a rare complication after a sling procedure, it should be considered in the patient who experiences progressive voiding difficulties, has transvaginal urinary leakage, and/or cannot be catheterized transurethrally. Expedient relief of the urinary retention and outflow obstruction is necessary, as well as careful surgical reconstruction of the urethra. To minimize the development of this complication we recommend plication of paraurethral connective tissue in the midline beneath the sling graft, and placement of minimal tension on the sling.
