OBJECTIVES:Urinary incontinence is a common problem of women’s health in the developed countries. Tension-free Vaginal Tape (TVT) and Trans Obturator Tape (TOT) are the most common minimal-invasive surgical therapy for incontinence treatment. The aim of our study is to compare the clinical outcomes of TVT and TOT surgery. METHODS:We randomly selected 200 women with TVT surgery and 200 women with TOT surgery (n=400) from 3 major Hungarian hospitals. Medical documentation of women underwent TVT or TOT sugary was analyzed retrospectively focusing on the frequency of complications, length of hospital stay, reoperation and vaginal erosion. Statistical analysis was performed by SPSS version 14 and included frequency analysis, confidence interval (CI) and chi square test. RESULTS:We found significantly higher complication rate at women with TVT surgery compared to TOT method: bladder injury (1% TVT versus 0.5% TOT, p=0.0183), abdominal pain (30.5% vs. 16.0%, p<0.0006), dysuria (21.0% vs. 13.0%, p=0.0332), urinary tract infections (13.5% vs. 6.5%, p=0.0196), retention (7.5% vs. 2.0%, p=0.0013), de novo urge (28.5% vs. 16.5%, p=0.007). The average length of hospital stay was also longer in TVT surgery (p<0.001). In case of TOT surgery, we found a significantly higher reoperation rate (2% vs. 6.5%, p=0.0257) and higher rate of vaginal erosion (0.0% vs. 4%, P=0.0043). CONCLUSIONS: Both type of minor surgical intervention can be considered as efficient way of incontinence treatment, however TVT surgery is associated with higher complication rate, longer average hospital stay, therefore TOT method should be the first choice, if applicable.
