A prospective randomized controlled trial (RCT) is performed in one tertiary referral urogynecology center from January 2012 thru December 2013. Study included women with pure or predominant urodynamic SUI confirmed during cystometry by positive standardized cough stress test (CST) with urinary bladder filling of 250 ml in lithotomy position. Study was carried out on a Caucasian Czech (central European) population. A study power analysis was calculated with an expected objective cure rate of minimum 80 % for both patient groups, false non-match rate (alpha) of 0.05, and false match rate (beta) of 0.10. A minimum sample size of 42 patients was required for each group.
