OBJECTIVE: To compare the change of urethral mobility after midurethral sling 
procedures in stress urinary incontinence with hypermobile urethra and assess 
these findings with surgical outcomes.
STUDY DESIGN: 141 women who agreed to undergo midurethral sling operations due 
to stress urinary incontinence with hypermobile urethra were enrolled in this 
non-randomized prospective observational study. Preoperatively, urethral 
mobility was measured by Q tip test. All women were asked to complete Urogenital 
Distress Inventory Short Form (UDI-6) and Incontinence Impact Questionnaire 
Short Form (IIQ-7) to assess the quality of life. Six months postoperatively, Q 
tip test and quality of life assessment were repeated. The primary surgical 
outcomes were classified as cure, improvement and failure. Transient urinary 
obstruction, de novo urgency, voiding dysfunction were secondary surgical 
outcomes.
RESULTS: Of 141 women, 50 (35. 5%) women underwent TOT, 91 (64.5%) underwent 
TVT. In both TOT and TVT groups, postoperative Q tip test values, IIQ-7 and 
UDI-6 scores were statistically reduced when compared with preoperative values. 
Postoperative Q tip test value in TVT group was significantly smaller than in 
TOT group [25°(15-45°) and 20° (15-45°), respectively]. When we compared the 
Q-tip test value, IIQ-7 and UDI-6 scores changes, there were no statistically 
significant changes between the groups. Postoperative urethral mobility was more 
frequent in TOT group than in TVT group (40% vs 23.1%, respectively). 
Postoperative primary and secondary outcomes were similar in both groups.
CONCLUSIONS: Although midurethral slings decrease the urethtal hypermobility, 
postoperative mobility status of urethra does not effect surgical outcomes of 
midurethral slings in women with preoperative urethral hypermobility.
