Genitourinary Fistula: An Indian Perspective

Proportions and determinants of successful surgical repair of obstetric fistula in low- and middle-income countries: A systematic review and meta-analysis

BACKGROUND

Obstetric fistula is a serious and debilitating problem resulting from tissue necrosis on the reproductive and urinary and/or lower gastrointestinal tract organs due to prolonged labor. Primary studies of the treatment of obstetric fistulae report significantly variable treatment outcomes following surgical repair. However, no systematic review and meta-analysis has yet estimated the pooled proportion and identified the determinants of successful obstetric fistula surgical repair.

OBJECTIVE

To estimate the proportion and identify the determinants of successful surgical repair of obstetric fistulae in low- and middle-income countries.

METHODS

The protocol was developed and registered at the International Prospective Register of Systematic Reviews (ID CRD42022323630). Searches of PubMed, Embase, CINAHL, Scopus databases, and gray literature sources were performed. All the accessed studies were selected with Covidence, and the quality of the studies was examined. Finally, the data were extracted using Excel and analyzed with R software.

RESULTS

This review included 79 studies out of 9337 following the screening process. The analysis reveals that 77.85% (95%CI: 75.14%; 80.56%) of surgical repairs in low and middle-income countries are successful. Women who attain primary education and above, are married, and have alive neonatal outcomes are more likely to have successful repair outcomes. In contrast, women with female genital mutilation, primiparity, a large fistula size, a fistula classification of II and above, urethral damage, vaginal scarring, a circumferential defect, multiple fistulae, prior repair and postoperative complications are less likely to have successful repair outcomes.

CONCLUSION

The proportion of successful surgical repairs of obstetric fistula in low and middle-income countries remains suboptimal. Hence, stakeholders and policymakers must design and implement policies promoting women's education. In addition, fistula care providers need to reach and manage obstetric fistula cases early before complications, like vaginal fibrosis, occur.

Causative factors, social and surgical outcomes of vesicovaginal fistulas treated via an abdominal transvesical approach: A single-center experience

OBJECTIVE

To study the demographics, and surgical and social outcomes of patients with fistula repair performed at our hospital.

METHODS

This cross-sectional study included 120 patients with fistula repair performed between 2014 and 2019 in the Urology Department of Lady Reading Hospital, Peshawar using an open transvesical repair method without omental interposition. Data were collected on patients' demographics, and social and surgical outcomes. Fistula severity was assessed using the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF).

RESULTS

About 80 (66.6%) fistulas were iatrogenic and 40 (33.3%) were ischemic, with 36 (90%) due to obstructed labor. The median age of patients was 36 years (29-40 years). The majority of the patients were multiparous and premenopausal (99; 82.5%). Fifty (56.5%) of the iatrogenic fistulas were due to non-obstetric hysterectomy, and 20 (25%) were due to cesarean hysterectomy. Women had the fistulas for 4-49 weeks before seeking treatment with an average ICIQ score of 18. In all, 73 (73%) of the fistula caused by delivery had involved stillbirths, 4 (3.96%) were early neonatal deaths, and nearly 25 (21%) of patients were divorced. About 114 (95%) of patients were completely cured on discharge.

CONCLUSION

Vesicovaginal fistula is a devastating condition, with a rising trend in iatrogenic fistulas in low-income countries. In the hands of experienced surgeons, trans-abdominal repair without omental interposition shows a high success rate.

Rising trends in iatrogenic urogenital fistula: A new challenge

Objective

To analyze trends in iatrogenic urogenital fistula among patients admitted for fistula repair at the Pakistan Institute of Medical Sciences, Islamabad.

Methods

In this longitudinal study, all patients who presented for fistula repair between 2006 and 2018 were included in the study. Patient data were collected on age, parity, and type and etiology of fistula, which was classified as ischemic or iatrogenic.

Results

Of 634 fistula patients, 371 (58.5%) had iatrogenic fistula, while 263 (41.5%) patients developed ischemic fistula due to obstructed labor. Mean age of patients was 31.6 years. Yearly trends showed an increase in iatrogenic fistula from 43.2% in 2006–2008 to 71.4% in 2017–2018. The major etiological contributor to iatrogenic fistula was hysterectomy (52.5%), followed by cesarean hysterectomy (26.4%), and cesarean delivery (19.9%).

Conclusion

A rising trend in iatrogenic fistula was observed. This emphasizes the need for optimization of surgical approaches and surgical skills. Moreover, gynecologic surgeries should be restricted to authorized gynecologic surgeons.

A rising yearly trend in iatrogenic fistula was observed over a 12‐year period in Pakistan.
