ABSTRACT

Objective To evaluate the efficacy and safety of tension free vaginal tape obturator technique (TVT-O) in females stress urinary incontinence (SUI).Methods From June 2008 to May 2012,156 cases of female SUI were treated with TVT-O procedure in our hospital.The mean age is 56.3 ±13.9 years.There were 79.5％ patients who suffered simple SUI while 20.5％ patients with SUI and urge urinary incontinence (UUI).The mean follow-up time was 16.5 months.All patient’s ICI-Q-SF scores and I-QOL scores were collected.The efficacy and safety of TVT-O were analyzed.Results The mean operative time was 34 ± 11 minutes and the mean estimated blood loss were 15 ± 9 ml.One hundred and forty-five cases were cured with TVT-O (92.9％) while 8 cases were improved (5.1％).The preoperative and postoperative ICI-Q-SF symptom scores were 8.2 ± 2.1 and 0.5 ± 1.3 while the I-QOL life quality scores were 28.5 ± 10.3 and 69.8 ± 9.9 respectively.There was statistical difference between the preoperative and postoperative scores (P ＜ 0.05 ).No bladder injury was recorded during the procedures.There were two cases whose vaginal walt were injured and repaired intraoperatively.No pelvic hematoma,long-term pain,sling erosion,infection and fistula were found in all cases.Three cases ( 1.9％ ) suffered temporary urinary retention and were cured by two weeks urethral catheterization.Conclusions TVT-O technique seems to be an easy and minimally invasive procedu(r)e with less complication,which supports its safety and reliability in the treatment of female SUI.
