Retrospective study on tension-free vaginal tape obturator (TVT-O)

Abstract

We aim to report the 3-year outcome and complications of the tension-free vaginal tape obturator (TVT-O) in treating female stress urinary incontinence (SUI). Retrospective analysis for complications and outcome of surgery was performed in 419 women undergoing the TVT-O from 2004 to 2006. Three patients (0.8%) with an isolated TVT-O had a blood loss of more than 200 ml. Two patients (0.5%) had bladder perforation. Out of 11 readmitted patients (2.6%), 10 were due to voiding difficulty. Six patients (1.4%) required tape loosening or division. Persistent pain occurred in 3.6% and erosion in 2.4% of patients. One hundred eighty-five patients (44.2%) came for follow-up at 3 years. The actual subjective and objective success rates were 89.7% and 99.9% at 3 years follow-up, respectively. With imputation, the 3-year subjective and objective success rates were 86.9% and 97.4%, respectively. The TVT-O is effective in treating female SUI with minimal complications.
