Methods: All women undergoing transobturator tension free vaginal tape procedure in our department for pure USI, done as a primary anti-incontinence procedure and as the sole procedure at time of surgery, will be invited to participate in the study and will receive an information leaflet and will sign a consent form. All would have had failed or declined physiotherapy treatment. Procedures mainly take place in the surgery unit under general anaesthesia; those that are done in the main surgical list are due to patients' associated medical conditions or needing spinal anaesthesia or living in remote areas. Randomisation will be performed using sealed opaque envelopes. TVT-O & TOT will be done as originally described, we do not perform cough stress test routinely. All patients will receive intra-operative; prophylactic antibiotics & anti- inflammatory drugs if not contraindicated. Lidocaine 1% will be infiltrated into the needle pathway at the end of the procedure; 10mls. on each side. Satisfactory postoperative voiding - for the purpose of this study - is defined as passing at least 200mls with post-voiding residual urinary volume <100mls assessed at least twice.
