title: Urodynamic assessment of anterior vaginal wall surgery: a randomized comparison between colporraphy and transvaginal mesh.
abstract: OBJECTIVE
  To investigate the urodynamic effects of anterior vaginal wall prolapse surgery using either trocar guided transvaginal mesh or colporraphy.
  
  
  METHODS
  A prospective, randomized multicenter trial enrolling 50 patients: 27 underwent anterior colporrhaphy and 23 anterior trocar guided transvaginal mesh. Urodynamic assessment was performed pre- and two months postoperatively.
  
  
  RESULTS
  De novo stress urinary incontinence was significantly more common after trocar guided transvaginal mesh surgery compared to colporraphy. In comparison to baseline urodynamics, transvaginal mesh surgery resulted in a significant decrease in maximal urethral closing pressures (MUCP) whereas conventional anterior colporraphy had no significant effect on urodynamic parameters.
  
  
  CONCLUSIONS
  Trocar guided transvaginal mesh of anterior vaginal wall prolapse results in a lowering of MUCPs and increases the risk for de novo stress urinary incontinence compared to colporraphy.
