Introduction and hypothesis
We describe the demographic profile, aetiology, management and surgical outcomes in women with genital tract fistula presenting to a tertiary urogynaecology unit.
Methods
This retrospective audit included 87 patients managed in our unit between 2008 and 2015. Frequencies and means with standard deviations are presented for categorical and continuous data. Continuous dependent variables are categorized as above or below the median for bivariate analyses performed using the chi-squared test (α = 0.05).
Results
The mean age of the women was 34.7 years, 64.4% were Black African, 70.2% were multiparous, 49.4% were married, 82.8% were employed, and 21.8% were HIV-infected, with 47.4% on antiretroviral treatment. Vesicovaginal (47.1%) and rectovaginal (41.4%) fistula were the most frequent injuries. The majority of the injuries (67.8%) were obstetric, with 26.4% occurring during caesarean delivery. Repair had been attempted previously in 43.7% of patients. In 63.2% of the repairs the approach was vaginal and in 35.6% abdominal. Interposition grafts were used in 23% of repairs. In 85.1% of patients the initial repair at our centre was successful. Patients with multiple repairs were more likely to have complications (p = 0.03). HIV infection was not significantly associated with complications.
Conclusions
A high rate of successful repair was found, with previous unsuccessful repairs associated with poorer outcomes, highlighting the need for centralized management.
