Stress Urinary Incontinence is defined as the involuntary  leakage  of urine which occurs during efforts that increase the intra-abdominal pressure such as during coughing, sneezing or even during exercise. It occurs when the urinary bladder pressure exceeds the urethral pressure. It is mainly caused due to the loss of urethral support, usually as a consequence of damage to pelvic structures during delivery. McGuire classification system describes 3 types of SUI. Type 1 and 2 occur due to urethral hypermobility and type 3 occurs due to intrinsic sphincter deficiency. The prevalence of SUI among adult women varies between studies, but it may be as high as 25% . Patients should be seen by a Urogynaecologist and a careful history with regards to voiding, urine leakage, frequency, urgency, straining, discomfort, use of drugs and recent surgery should be taken.

Surgical trauma acts as a stimulus for acute-phase response (APR) and is thought to be mediated through cytokines such as interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α) and C-reactive protein (CRP). Serum IL-6 levels are an easily measurable  marker and has been shown to correlate with the severity of  the tissue trauma, blood loss, and the duration of surgical procedure.Among all the available markers, IL-6 correlates best with the magnitude of injury and the systemic inflammatory response. It is thought to be the primary mediator of inflammation and regulator of the hepatic production of CRP. Comparison of preoperative and postoperative serum inflammatory markers can help to assess the stress response of the body in terms of the severity of tissue trauma with different procedures and establish the better choice.
