Association between parity and fistula location in women with obstetric fistula: a multivariate regression analysis

Vesicovaginal Fistulas: Prevalence, Impact, and Management Challenges

Background and Objectives: Vesicovaginal fistulas (VVFs) are an abnormal communication between the vagina and bladder and the most common type of acquired genital fistulas. This review will address the prevalence, impact, and management challenges of VVFs. Materials and Methods: Epidemiologic studies examining VVFs are considered. In addition, publications addressing the treatment of VVFs are reviewed. Results: VVFs in developing countries are often caused by obstructed labor, while most VVFs in developed countries have iatrogenic causes, such as hysterectomy, radiation therapy, and infection. The reported prevalence of VVFs is approximately 1 in 1000 post-hysterectomy patients and 1 in 1000 deliveries. VVFs affect every aspect of quality of life, including physical, mental, social, and sexual aspects. Prevention of VVFs is essential. Early diagnosis is necessary to reduce morbidity. Nutrition, infection control, and malignancy detection are important considerations during evaluation and treatment. Conservative and surgical treatment options are available; however, these approaches should be customized to the individual patient. The success rate of combined conservative and surgical treatments exceeds 90%. Conclusions: VVFs are considered debilitating and devastating. However, they are preventable and treatable; key factors include the avoidance of prolonged labor, careful performance of gynecologic surgery, and early detection.

Omental patch for lower uterine segment repair during caesarean section

Increasing rates of caesarean section have contributed to a higher number of complications such as vesicouterine fistula. A G6P5 woman in her early forties presented for her third elective repeat caesarean section. At the time of delivery, there was uterine dehiscence and the fetus was visible through a large 7×5 cm transparent window in the lower segment. After delivery of the baby, the uterus was unable to be repaired with sutures so an omental patch was fixed on the lower segment to facilitate healing. It is hypothesised that the angiogenic properties of the omentum may have promoted healing of the uterine defect and reduced the risk of vesicouterine fistula by providing a protective barrier. The patient recovered well and by 4 months post partum, her menstrual cycle had returned. Thereby, the use of an omental patch during uterine repair may reduce long-term complications associated with repeat caesarean section.

Research in Obstetric Fistula: Addressing Gaps and Unmet Needs

Although obstetric fistula has likely plagued women since the beginning of time, very little research proportionally exists. This article summarizes the most substantial research on the topic and delineates research gaps and future needs. Existing research demonstrates that access to care is the underlying cause of obstetric fistula and that the first attempt at closure holds the highest chance at success, ranging between 84% and 94%. For simple cases, 10 days of a catheter is sufficient, although what constitutes as simple is unclear. Circumferential fistulas are at high risk for ongoing urethral continence. Psychosocial programs are helpful for all women, but those who are "dry" tend to reintegrate into society, whereas those still leaking need additional support. Prenatal care and scheduled cesarean delivery are recommended to avoid another fistula. Gaps in research include accurate prevalence and incidence, interventions to improve access to care, surgical technique, especially for complex cases, and ways to prevent ongoing incontinence, among many others. In all areas, more rigorous research is needed.
