title: Complications of synthetic slings used in female stress urinary incontinence and applicability of the new IUGA-ICS classification.
abstract: OBJECTIVE
  To analyze different complications of synthetic suburethral slings, and to apply the new "IUGA-ICS classification of complications directly related to the insertion of prosthesis (meshes, implants, tapes) and grafts in female pelvic floor surgery" to the list of complications, check its applicability, and give suggestions regarding possible improvements.
  
  
  METHODS
  This study is an analysis of complications of synthetic suburethral slings. Data on type of complication, time interval between the insertion of the prosthesis and the onset of symptoms of complication, type and nature of prosthesis, and management process were documented. Additional descriptions of the sling position in relation to lower urinary tract, shrinkage or prominence of the prosthesis, and intra-operative nature of the prosthetic material were collected for analysis.
  
  
  RESULTS
  From the year 2003 to 2010, 376 women with complications of synthetic suburethral slings were managed surgically and the data were analyzed. Overactive bladder (OAB) at 54%, lower urinary tract obstruction (48%), vaginal exposure (19%), and pain (14%) were the most frequent complications. Infection, fistulae, urinary tract penetration, and groin/thigh pain were other complications. The new IUGA-ICS classification could be applied to most of the types of complications, a notable exception being de novo development of overactive bladder. Also category 4B of IUGA-ICS classifications encompasses a wide clinical variety of complications and may need reconsideration.
  
  
  CONCLUSIONS
  De novo OAB seems to be the commonest complication of synthetic suburethral slings, followed by obstruction, vaginal exposure, and long term pain. The new IUGA-ICS classification on complications has good general applicability; some minor changes may be useful in the future.
