Abstract: Objective: To explore the prevention and treatment of vesicovaginal fistula (VVF) after laparoscopic hysterectomy. Methods: 6 cases of VVF after laparoscopic hysterectomy for hysteromyoma or adenomyosis in the Yijishan Hospital of Wannan Medical College from January 2015 to December 2018 were retrospectively analyzed, age 39-52 years old, 6 days to 1 month after hysterectomy. The patients underwent cystoscopy and laparoscopy after diagnosis, and the bladder fistula was repaired during operation. Results: Of the 6 repair operations, 1 was completed by laparoscope, 1 by vagina, 3 by direct laparotomy, and 1 by laparoscopic repair and then convert to laparotomy. All operations were successful and healed well. No urine leakage occured during postoperative follow-up. Conclusions: Unclear anatomical level and improper operation are the main causes of VVF. Once discovered after the operation, it can be directly repaired or repaired after tissue healing, with satisfactory results.
