Cervical cancer in the Russian Federation and the risks of vaginal fistula

This review aims to provide up-to-date information on the factors associated with an increased risk of vaginal fistula in women with cervical cancer, as well as on methods of their prevention and treatment. It includes data on various types of vaginal fistulas in cervical cancer patients and risk factors for their development, according to foreign and Russian research articles published over the last 20 years. Cervical cancer is one of the most challenging oncological diseases in the Russian Federation, because it is detected at stage III–IV in more than 30 % of women. Such a high incidence of cervical cancer and the need for radiotherapy determine high risk of fistulas, which significantly impairs the quality of life. Thus, identification of factors associated with vaginal fistulas, as well as methods of their prevention and treatment remains a highly relevant task for the Russian healthcare system.

Vesico-Vaginal Fistula Repair by a Vaginal Approach

<b><i>Introduction:</i></b> The aim of this study is to determine the outcome of surgically treated vesico-vaginal fistulae (VVaFs) using a transvaginal approach with a Latzko technique. <b><i>Methods:</i></b> A retrospective chart study was conducted at the Department of Urology, Radboud University Medical Centre. Surgical approaches to repair VVaF, from 2014 to September 2020, were selected. Patients who underwent a transvaginal approach were included. The primary objective was fistula closure. Secondary objectives were predictive factors for the outcome of the surgical procedure, for example, patient characteristics, leakage on cystography 2 weeks postoperative, and surgery time. <b><i>Results:</i></b> Thirty-one patients had surgery for VVaF. Twenty-five procedures (81%) were performed transvaginally. Thirteen of these (52%) had successful transvaginal closure after the first attempt. Seven out of 12 had their second attempt at the time of analysis, of which 4 (57%) were successfully closed thereafter. After either 1 or 2 attempts with the transvaginal approach, 17 (68%) of the VVaFs were successfully closed, but 79% if patients who did not yet had a second attempt were taken into account with the current success extrapolated. Only few minor complications were observed. <b><i>Conclusion:</i></b> Transvaginal closure of VVaFs with a Latzko technique is successful in about 79% in either 1 or 2 attempts, with few minor complications. A second attempt in closing the fistula with a transvaginal approach is useful, and a previous transvaginal attempt is not a contraindication for a second transvaginal attempt in closing the VVaF surgically.
