Retrospective review of intra- and post-operative complications with minimal versus large space of Retzius infiltration at the time of retropubic TVT placement

Introduction and hypothesis A concern when using the retropubic tension-free vaginal tape (TVT) for stress urinary incontinence (SUI) is bladder perforation. This article describes a technique hypothesised to reduce the risk of intra-operative bladder perforation, termed the large space of Retzius infiltration (LSORI) technique. A large volume of infiltration of 360 ml saline-vasoconstrictor solution (180 ml × 2) into the space of Retzius (LSORI) at the time of retropubic TVT insertion will reduce the incidence of intra-operative bladder perforations.
