Urodynamic evaluation after vaginal repair and colposuspension

Abstract

Eighty-six consecutive patients with urinary incontinence and/or genital prolapse were evaluated by urodynamic examination and colpo-cysto-urethrography before and after vaginal repair or colposuspension procedures. None of the patients had had a previous operation for genital or lower urinary tract disorders. The follow-up period exceeded one year. In the vaginal repair group there was a significant decrease in opening time and an increase in pre-micturition pressure and maximum flow rate. In the colposuspension group there was an increase in pre-micturition pressure, opening pressure, mean micturition pressure, post-micturition pressure, flow time and pressure time and a decrease in maximum flow and mean flow. Vaginal repair appears to reduce urethral resistance, while colposuspension tends to increase outflow resistance. Colposuspension should be avoided in patients with poor or absent detrusor function.
