Stress urinary incontinence (SUI) affects upwards of 40 % of American women [ 1 ]. Over the past several years, surgical treatment of SUI has evolved from mainly transvaginal needle suspensions, anterior vaginal wall plications, and retropubic suspensions to various types of slings, most commonly midurethral polypropylene slings. Sling surgeries for SUI can be classifi ed by composition (autologous fascia, biologic or synthetic nonabsorbable materials), location of the sling (midurethral or beneath the bladder neck), and approach of placement (retropubic or transobturator). A full discussion of all the types of slings and sling complications is beyond the scope of this article but specifi c operations will be discussed where appropriate. The majority of the following discussion concerns midurethral slings via transobturator or retropubic approaches. Surgical treatment of SUI comprises some of the most commonly performed operations in the United States. Thus, it is important to understand how to avoid and, when necessary, diagnose and treat complications related to these surgeries.
Prevention of ComplicationsAlthough most complications are treatable and reversible, the optimal scenario is to prevent or minimize potential for adverse outcomes. This process begins in the preoperative period, initiated during the diagnostic evaluation and work-up. When determining the optimal surgical therapy for patients with urinary incontinence, many factors should be considered, including etiology and type of urinary incontinence and/or prolapse, bladder capacity, renal function, sexual function, medical comorbidities, or concurrent abdominal or pelvic pathology requiring surgical correction, prior abdominal and pelvic surgery, and fi nally, a patient's suitability for and willingness to accept the risks of surgery.Standard preoperative evaluation of an individual with stress incontinence should include a focused history and physical, objective demonstration of SUI, an assessment of post-void residual urine volume and urinalysis and culture if warranted [ 2 ]. It is recommended that the incontinence be characterized and symptom impact and patient expectations be assessed. Additional studies may be indicated to evaluate the lower urinary tract, including pad tests and voiding diary, cystoscopy, and imaging. Furthermore, voiding function should be characterized, with noninvasive fl ow and post-void residual measurements, with invasive urodynamics reserved for patients with abnormal fi ndings, mixed incontinence or
