Mainz II urinary diversion in low-resource settings: patient outcomes in women with irreparable fistula in Malawi.

BACKGROUND: Obstructed labor leading to a vesicovaginal fistula remains a devastating outcome of childbirth in low-resource countries. Women with an irreparable vesicovaginal fistula may be candidates for a urinary diversion, such as the Mainz II modified ureterosigmoidostomy procedure. Previous reviews state that the procedure should be considered in low-resource countries. However, given the limited duration of postoperative follow-up, these studies do not adequately represent the long-term morbidity and mortality that is likely associated with this procedure. We present data that strongly support avoiding the procedure in low-resource countries. OBJECTIVE: This study aimed to evaluate the postoperative status of the patient (dead, alive, lost to follow-up) and time to death following the Mainz II procedure. STUDY DESIGN: This is a case series including 21 patients who underwent a Mainz II urinary diversion from April 2013 to June 2015 for management of irreparable vesicovaginal fistula at the Fistula Care Centre in Lilongwe, Malawi. Patients were seen postoperatively at 3, 6, 9, and 12 months, followed by every 6 to 12 months thereafter. Descriptive statistics were performed to summarize the data. RESULTS: During the postoperative period, 8 (38.1%; 8/21) patients died, 5 (23.8%; 5/21) were lost to follow-up, and 8 (38.1%; 8/21) are currently alive and followed up at the Fistula Care Centre. We strongly suspect that 7 of the 8 deaths were related to the procedure given that the patients had illnesses that exacerbated the metabolic consequences of the procedure. The eighth patient died after being attacked by robbers. Unfortunately, the exact cause of death could not be determined for these patients. Given that most of the suspected illnesses would be treatable in an otherwise healthy patient, even in this low-resource setting, we surmised that the metabolic compromise from the Mainz II procedure likely contributed to their untimely death. The average time from procedure to death was 58 months, with the earliest death at 10 months and the most recent at 7 years after the procedure. CONCLUSION: The Mainz II procedure is an option for patients with irreparable fistula. However, it should likely not be performed in low-resource countries given the long-term complications that often cannot be adequately addressed in these settings, leading to significant morbidity and mortality.

Obstetric fistula scoring tool for surgical trainees.

OBJECTIVE: To examine the ability of a previously published risk score to predict incontinence at discharge in women with vesicovaginal fistulas (VVF) and to examine how the score correlates with an independent assessment of surgical skill. METHODS: This is a retrospective cohort study including cases from January to June 2018. We evaluated operative records for factors associated with incontinence at hospital discharge, as well as relationships between a risk score cut-point of 20 or more and surgical skill level. All women with VVF undergoing vaginal repair were included. RESULTS: A total of 176 individuals underwent repair; 23 were performed by beginner, 85 by intermediate, 47 by advanced, and 21 by expert surgeons. Factors found significantly associated with incontinence at hospital discharge included Goh classification, fistula size, circumferential fistula, and vaginal scarring. A score of 20 or more predicted residual incontinence with a negative predictive value of 92% (odds ratio 7.75, 95% confidence interval 2.95-22.34). Applying the score cut-point of 20 or more, we found an increased proportion of "high-risk" cases allocated to surgeons with an increasing level of expertise. CONCLUSION: The correlation we observed between a risk score cut-point of 20 or more, continence status, and an independent assessment of surgical skill is promising. Although the risk score is not meant to replace clinical judgment, it may provide a surgical trainee with an objective method of determining whether to operate or refer for optimal outcomes.

A retrospective review to identify criteria for incorporating the Singapore flap and gracilis muscle flap into obstetric fistula repair.

OBJECTIVE: To identify criteria to guide surgeons regarding indications for use of the Singapore and gracilis muscle flaps in obstetric fistula repair. METHODS: This is a retrospective case series. Obstetric fistula surgeons in Lilongwe, Malawi, have been incorporating plastic surgery techniques with the Singapore and gracilis muscle flaps since collaborating with plastic surgeons in 2016. We describe the surgical outcomes of procedures utilizing each flap individually and those using both. RESULTS: Between February 2016 and June 2019, 69 patients received a flap at the time of obstetric fistula repair at the Fistula Care Center in Lilongwe, Malawi. A total of 32 (46.4%) received a Singapore flap, 20 (29.0%) received a gracilis flap, and 17 (24.6%) received both types of flap. CONCLUSION: Based on our outcomes, we note the possible advantage of incorporating the gracilis flap even when it is thought that the Singapore flap is sufficient. However, more data are needed.

Sexual Function Before and After Vesicovaginal Fistula Repair.

INTRODUCTION: Women with vesicovaginal fistulas often experience a disruption in their normal lives, including sexual relationships, because of urinary incontinence. AIM: Although surgery repairs the urinary leakage, it is not known how surgery might affect sexual function positively or negatively. METHODS: 119 women were enrolled before surgery and interviewed including a revised Female Sexual Distress Scale (FSDS-R) score and examined for vaginal length, caliber, and pelvic floor strength. MAIN OUTCOME MEASURES: Approximately one third of women return to normal sexual function after repair, although a minority experience de novo dysfunction. RESULTS: 115 women completed follow-up 6 to 12 months after surgery. Approximately one third (35.6%, n = 41) stated that intercourse had returned to the way it was before a fistula. Forty-four women (40%) report sexual problems after the fistula developed; 15% due to incontinence and 23.5% due to pain. Fourteen women (12.2%) stated that they experienced problems with intercourse since surgery; 50% due to incontinence during intercourse and 50% due to pain. Nineteen of the participants (16.5%) scored in the range of dysfunction as assessed by the FSDS-R tool after surgery. Fibrosis did not significantly change and was not found to be associated with sexual function. Vaginal length was found to decrease on average by 5 mm. Of the variables examined, the factors statistically significantly associated with dysfunction included a larger-size fistula as determined by the Goh classification (> 3 cm diameter) and decreased vaginal caliber. FSDS-R scores drastically decreased from before to after surgery and the reason for problems with intercourse changed from leaking urine before surgery to lack of partner and concern for HIV infection. CLINICAL IMPLICATIONS: Women with large fistulas and decreased vaginal calibers are at high risk for sexual dysfunction and should be counseled appropriately preoperatively and offered surgical and medical interventions. STRENGTHS & LIMITATIONS: Physical parameters were combined with qualitative interviews and FSDS-R scores to contextualize sexual health before and after surgery. Limitation is the brief follow-up of 6-12 months after surgery as many women were still abstaining from sexual activity. CONCLUSION: Sexual dysfunction is a complex issue for women with obstetric fistulas; although many women do not continue to experience problems, several need ongoing counseling and treatment.
