Urethral closure pressure profile (UCPP) during stress in patients with obstructive sling complications. a Before sling incision: a dramatic increase in urethral closure pressure during coughing is apparent at the site of the sling, resulting in continence during stress and obstructive complications (voiding dysfunction such as staccato micturition, urinary flow rate reduction, and elevated residual urine). b Postoperative profile after sling incision: sling incision eliminates the stop cock phenomenon, which results in normal micturition and residual urine, but stress urinary incontinence
