Summary— To evaluate urodynamic effects of modified Burch colposuspension, 24 patients with stress urinary incontinence were investigated before and 6 to 9 months after the operation. A new method of urodynamic evaluation was performed using a multitransducer‐catheter, 5 microtransducers inside the urethra and 1 in the bladder, connected to a computer and graphic plotter. Single coughs were analysed with the catheter in a fixed position and the patient in the standing position. The operation, which was successful, in all but 1 patient, did not alter urethral pressure at rest, but urethral closure pressure at stress after the operation (mean 45.0 cm H 2 O (SD 21.6)) was significantly higher ( P < 0.005) than the – 3.6 cm H 2 O (SD 10.2) recorded before the operation. The pressure transmission ratio was less than 100% in 22 patients before the operation and more than 100% in 18 patients afterwards, the pre‐and post‐operative mean values being 78.9% (SD 11.9) and 109.5% (SD 17.2) respectively ( P < 0.0005). Burch colposuspension markedly improves urethral closure function as evaluated by this method, which analyses the pressure data at different points of the urethra and bladder during one single cough.
