Description of intervention(s) / exposure
The original tension free vaginal tape procedure was described using a cough test but the test has been abandoned by many. We are studying whether or not this is an important part of the procedure. Both groups undergo the tension free vaginal tape procedure. This involves the insertion of a suburethral tape passed from the vagina and brought out suprapubically attached to 2 needles which are then cut off the tape. The tape then provides support for the urethra when the abdominal and pelvic pressure is raised eg. during coughing or exercise and reduces or completely stops the severity of urine leaked.
The intervention group do not receive the cough test. The control group do. The cough test involves waking the patient up after the tape has been passed and asking them to cough. The tape is then adjusted to the surgeons satisfaction allowing a drop of urine to pass but no more during coughing. The intervention group takes approximately 10 to 15 mins less than the control group. The procedure take approximately 30 to 35 mins for the control group.
