Urodynamic study
Continence
URETHRA
The urodynamic study was performed according to the International Continence Society (ICS) standards. To conduct urodynamic investigations, a multichannel urodynamic system (Laborie Medical Technologies Corp., Toronto, Canada) was used. Patients were assessed in a sitting position. UDI comprised same-session repeat filling cystometry, pressure flow study and a resting as well as a stress urethra pressure profile. The bladder was filled with a body-temperature (36°C) 0.9% sodium chloride solution at a speed of 20–30 ml per minute. For simultaneous measurements of vesical and abdominal pressure a 7-French transurethral and rectal latex-free, single-use catheter (T-DOC®, Air-Charged Dual and Abdominal catheter, Laborie Medical Technologies Corp., Toronto, Canada) was used. For the UPP measurement the bladder was prefilled with 150 ml and the catheter was withdrawn by a mechanical device at a rate of 1 mm/s. The urethral closure pressure (UCP) profile, the maximum urethral pressure (MUP), the maximum urethral closure pressure (MUCP) and the functional urethra length (FUL) were obtained from the UPP.
