Clinical comparison on efficacy of tension-free vaginal tape and transobturator tension-free vaginal tape in old female patients with stress urinary incontinence

Objective To compare the outcome of surgical treatment of female stress urinary incontinence(SUI) with tension-free vaginal tape(TVT) and transobturator tension-free vaginal tape(TVT-O) and to estimate the change in life quality of old female patients with SUI before and after surgical treatment.Meanwhile,the time and volume of blood loss in operation were compared.Methods A total of 67 women with SUI were assigned to undergo either TVT or TVT-O surgery.Therapeutic effect was evaluated according to classification of Grouts-Blaivas outcome scores.The evaluation of change in life quality before and after surgical treatment was based on the influence of incontinence to quality of life in stress(I-QOL).Results Both TVT and TVT-O have advantages of reliability and mini-invasiveness.The efficacy of TVT is similar to that of TVT-O(P0.05).After operation,the status of mental health,physiological health,social activity and family condition of patients had been improved respectively(allP0.01),expect their sexual function.Meanwhile,the operation time in TVT group is longer than that of TVT-O group,and the volume of blood loss in TVT group is more than that of TVT-O group.Conclusion The tension-free urethral suspension is effective and safe for treatment of SUI in old women and it may improve their life quality.The operation time of TVT group is longer than that of TVT-O group,and the volume of blood loss in TVT group is more than that of TVT-O group.
