Aims:
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.
Conclusion:
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.
