Research in Obstetric Fistula: Addressing Gaps and Unmet Needs

Development and Pilot Test of a Group Cognitive Behavioral Intervention for Women Recovering From Fistula Repair Surgery in Ethiopia

Obstetric fistula is a serious complication that affects thousands of women in low-income countries. Women who suffer from obstetric fistulae are at risk of developing mental health problems, but to date most interventions have focused on repairing the physical consequences of fistulae through surgery. The goal of the current study is to develop an evidence-based intervention targeting symptoms of depression, anxiety, and trauma in women recovering from fistula repair surgery. First, hospital staff and patients awaiting surgery at a fistula hospital in Ethiopia participated in qualitative interviews to provide information on the mental health needs of women with fistulae, how the hospital tends to these women's psychological needs, and the training needs of staff members. Data from these interviews were used to develop the COFFEE intervention (CBT with Obstetric Fistula for Education and Empowerment). COFFEE is a modular, group intervention that teaches psycho-education, behavioral activation, relaxation, problem solving, cognitive restructuring, and includes a trauma narrative. Patients then participated in an open trial of the COFFEE intervention at the University of Gondar Hospital. Five separate groups were conducted with 24 women who were enrolled post-fistula repair surgery. Women completed pre-treatment self-report questionnaires, participated in group sessions conducted by nurses (with 8 sessions delivered across 10–14 days), and were assessed post-treatment and at 3-month follow-up. Results indicate a significant reduction on depression and anxiety symptoms scores across the three time points [F_{(2, 40)} = 68.45, p < 0.001 partial η² = 0.774]. Additionally, there was a significant decrease in traumatic stress scores from baseline to post-treatment [F_{(1.10, 21.98)} = 100.51, p < 0.001 partial η² = 0.834]. Feedback forms completed by nurses and patients suggest the intervention was well-received. Results of this open-trial suggest the COFFEE intervention is feasible, acceptable, and clinically beneficial to treat symptoms of depression, anxiety, and traumatic stress in women post-fistula repair surgery in a hospital setting.

Rectovaginal Fistulas Secondary to Obstetrical Injury

Rectovaginal fistula (RVF), defined as any abnormal connection between the rectum and the vagina, is a complex and debilitating condition. RVF can occur for a variety of reasons, but frequently develops following obstetric injury. Patients with suspected RVF require thorough evaluation, including history and physical examination, imaging, and objective evaluation of the anal sphincter complex. Prior to attempting repair, sepsis must be controlled and the tract allowed to mature over a period of 3 to 6 months. All repair techniques involve reestablishing a healthy, well-vascularized rectovaginal septum, either through reconstruction with local tissue or tissue transfer via a pedicled flap. The selection of a specific repair technique is determined by the level of the fistula tract and the status of the anal sphincter. Despite best efforts, recurrence is common and should be discussed with patients prior to repair. As the ultimate goal of RVF repair is to minimize symptoms and maximize quality of life, patients should help to direct their own care based on the risks and benefits of available treatment options.

Predictors of Urinary Retention After Vesicovaginal Fistula Surgery: A Retrospective Case-Control Study

OBJECTIVE

The objective of this study is to determine the predictors for urinary retention after vesicovaginal fistula surgery.

METHODS

This was a retrospective case-control study of women who underwent vesicovaginal fistula repair between January 2014 and December 2017 at the Fistula Care Centre in Lilongwe, Malawi. Cases were defined as patients with documented urinary retention, defined as a postvoid residual that is 50% greater than the total void of at least 100 mL. The cases and controls were matched by the 3 components of the Goh classification system in a ratio of 1:5. Univariate analysis was used to detect differences between demographic, clinical characteristics, and operative techniques between cases and control. Logistic regression analysis was performed for estimation of odds ratios (ORs).

RESULTS

There were no statistically significant differences between the 40 cases and 187 controls, when comparing age, gravidity, parity, body mass index, and length of postoperative catheterization. The median amount of postvoid residual noted at the time of diagnosis was 240 mL (range, 55-927 mL). Odds for urinary retention was 3 times higher among those with vertical closure than patients with horizontal closure of the bladder (OR, 2.91; 95% confidence interval, 1.35-6.20). Patients with prior fistula repairs were significantly less likely to develop urinary retention compared to those receiving surgery for the first time (OR, 0.27; 95% confidence interval, 0.10-0.67).

CONCLUSIONS

Vertical closure of the bladder and patients without a history of prior fistula repairs are predictors for developing urinary retention after fistula repair surgery.

Complex circumferential obstetric fistula-a urologist's worst nightmare

INTRODUCTION AND HYPOTHESIS

Circumferential vesicourethrovaginal fistula is a severe form of obstetric injury that is challenging to repair and carries a poor prognosis related to eventual continence. Here, we report the successful repair of a circumferential vesicovaginal fistula associated with near total loss of the urethra. The use the anterior bladder flap technique along with an autologous rectus sheath sling resulted in the creation of an effective continence unit.

METHODS

A 31-year-old woman had a history of obstructed labor resulting in intrauterine death followed by trans-abdominal hysterectomy for postpartum hemorrhage. Since then she had had total urinary incontinence. She had an attempted repair through the vaginal route, which had failed. Physical examination and endoscopic evaluation revealed a large vesicourethrovaginal fistula with near total loss of the urethra leaving only the meatus. Intraoperatively, we found that it was a large circumferential defect in the infratrigonal region with no anterior bladder wall left at the site of the fistula.

RESULTS

We performed an anterior bladder flap procedure as described by Tanagho along with an autologous rectus sheath sling for additional support. Postoperatively, the patient was completely continent.

CONCLUSIONS

The anterior bladder onlay flap technique, which has been used extensively for female urethral reconstruction in developed countries, along with an autologous rectus sheath sling is an effective technique for management of circumferential fistulas allowing good continence. Incorporation of this technique into the armamentarium of surgeons managing fistulas in developing countries will go a long way toward helping this unfortunate group of women with this morbid complication of obstructed labor.

Pubococcygeal Sling versus Refixation of the Pubocervical Fascia in Vesicovaginal Fistula Repair: A Retrospective Review

Urethral incontinence is an issue for approximately 10–15% of women with an obstetric fistula. Various surgical interventions to prevent this exist, including the pubococcygeal sling and refixation of the pubocervical fascia. Neither has been evaluated in comparison to one another. Therefore, this retrospective evaluation for superiority was performed. The primary outcome was urinary stress incontinence, and secondary outcomes were operative factors. There were 185 PC slings, but 12 were excluded because of urethral plications. There were 50 RPCF procedures, but 3 were excluded because of urethral plications. Finally, there were 32 cases with both PC sling and RPCF procedures. All groups demonstrated a higher than expected fistula repair rate with negative dye tests in 84% of the PC sling group, 89.9% in the RPCF group, and 93.8% in the RPCF and PC groups. There were no statistically significant differences found in continence status between the three groups. Of those who underwent PC slings, 49% were found to have residual stress incontinence. Of those who underwent RPCF, 47.8% had stress incontinence. Of those with both techniques, 43.8% had residual stress incontinence. Pad weight was not significantly different between the groups. As there is no statistically significant difference, we cannot recommend one procedure over the other as an anti-incontinence procedure. The use of both simultaneously is worth investigating.
