This is a prospective study to assess the feasibility and success of performing an intra-operative standing cough test and the correlation with the long term success of the sling surgery.

The goal is to seek correlation or disparity between the supine versus the sitting cough test, supine (lying down) versus standing cough test and sitting versus the standing cough test performed at a constant bladder volume; empty in the office and full in the operating room. Secondary objective is to test if the intra-operative standing cough test at fullness correlates with long term success of the sling surgery.

Inclusion Criteria:

• Patients who present with stress-dominant urinary incontinence
• Patients who have undergone a stress test documentation both in the supine and standing/sitting position.
• Patients who have completed child bearing.
• Patients between 21 and 89 years of age.

Exclusion Criteria:

• Patients who do not agree to participate and do not sign the informed consent.
• Patients undergoing concomitant surgery
• Patients undergoing surgery under anesthesia.
