[Urodynamic results of Burch colposuspension]

Between 1984 and 1987 31 patients underwent a colposuspension according to Burch for stress urinary incontinence. Seventeen women were available for clinical and urodynamic follow-up after an average of 17.6 months. Clinically, 2 women had postoperative stress-urge incontinence and 2 had stress incontinence only. 13 (77%) patients were continent while straining, 9 (53%) patients complained of urge and voiding disorders, 7 reported post micturition dribble, 2 patients lost urine during intercourse. Urodynamically, 14 (82%) patients were continent during straining, 3 showed mild stress incontinence. The functional urethra length and urethral closure pressure at rest were unchanged. The urethral pressure under stress, depression quotient, and transmission factor increased significantly. The average uroflow sank from 16.8 ml/s to 7.8 ml/s, reflecting the subjective voiding disorders. Bladder compliance was unchanged. We saw no autonomous detrusor contractions and thus no correlation with subjective urge complaints.
