Abstract:
Objective:This study aimed to identify the risk factors for genitourinary fistulas and delayed fistula recognition after radical hysterectomy for cervical cancer.
Methods:This study was a retrospective analysis of data collected in the Major Surgical complications of Cervical Cancer in China (MSCCCC) database from 2004–2016. Data on sociodemographic characteristics, clinical characteristics, and hospital characteristics were extracted. Differences in the odds of genitourinary fistula development were investigated with multivariate logistic regression analyses, and differences in the time to recognition of genitourinary fistula were assessed by Kruskal–Wallis test.
Results:In this study, 23,404 patients met the inclusion criteria. Surgery in a cancer center, a women’s and children’s hospital, a facility in a first-tier city, or southwest region, stage IIA, type C1 hysterectomy, laparoscopic surgery and ureteral injury were associated with a higher risk of ureterovaginal fistula (UVF) (p<0.050). Surgery in southwest region, bladder injury and laparoscopic surgery were associated with greater odds of vesicovaginal fistula (VVF) (p<0.050). Surgery at cancer centers and high-volume hospitals was associated with an increase in the median time to UVF recognition (p=0.016; p=0.005). International Federation of Gynecology and Obstetrics (FIGO) stage IIA1-IIB was associated with delayed recognition of VVF (p=0.040).
Conclusion:Intraoperative urinary tract injury and surgical approach were associated with differences in the development of UVFs and VVFs. Patients who underwent surgery in cancer centers and high-volume hospitals were more likely to experience delayed recognition of UVF. Patients with FIGO stage IIA1-IIB disease were more likely to experience delayed recognition of VVF.
