To explore the advantages and clinical application value of individualized interventional therapy in the diagnosis and treatment of different types of vesicovaginal fistula (VVF).

A retrospective analysis was performed on 41 patients diagnosed with VVF in the First Affiliated Hospital of Zhengzhou University from April 2017 to August 2019. Different interventional treatment methods were selected according to the patient's VVF type. Among them, 18 patients with VVF after radiotherapy for cervical cancer received concurrent bilateral percutaneous nephrostomy and ureter occlusion stent placement. 22 patients with VVF and lower ureteral stenosis after radiotherapy for cervical cancer were treated with bilateral percutaneous nephrostomy. One case with VVF caused by cystoscopy injury due to long-term urinary system inflammation was treated with short-term ureter balloon occlusion combined with nephrostomy. The improvement of symptoms and postoperative complications were observed. The differences of urine white blood cell count, vaginal fluid volume, creatinine and urea nitrogen were compared before and one week after operation.

All 41 patients were successfully treated with interventional treatment.The symptoms of urine leakage disappeared in all patients immediately after the procedure.Compared with the preoperative period, urine white blood cell count and the amount of vaginal fluid in the first week after operation were significantly different (P < 0.05). And there was no statistically significant difference in creatinine and urea nitrogen (P > 0.05). No serious complications were observed after treatment.

Individualized interventional therapy for VVF patients is safe and effective, and appropriate treatment methods should be selected according to the patient's condition and willingness to achieve the best therapeutic effect.
