Stress urinary incontinence (SUI) is a common problem affecting up to 35% of the female population. SUI results from a laxity of the pelvic floor anatomy, neuromuscular injury of the external urinary sphincter mechanism or both. Evaluation of the condition includes careful history, physical examination and urine analysis. Additional tests such as urodynamic studies and cystoscopic inspection are determined on a case by case basis. Treatment options range from behavior modification to medications to surgery. We present a review of the incidence, pathophysiology, evaluation and medical/surgical treatment options for SUI.
