Uterovesical fistulas as obstetric complications: Diagnosis, management and prognosis (Review)

Urogenital fistulas are abnormal communications between the female genital and urinary tract; while such fistulas, which are the most commonly encountered, are located between the vagina and urinary bladder and are caused by the local extension of a tumoral process. Another frequently encountered cause is represented by the obstetric one, leading to the development of uterovesical fistulas. However, many questions regarding the diagnosis and management of uterovesical fistulas remain unanswered. Therefore, the aim of this article was to review the existent data so far, with special attention being focused on the pathogenic mechanisms leading to this complication, on the modalities of diagnosis, and on the possible therapeutic strategies. Therefore, according to the time of diagnosis, uterovesical fistulas can be classified as early fistulas, diagnosed in the first months postoperatively and late fistulas, diagnosed within several years from the initial surgical procedure. For early fistulas, a conservative therapeutic strategy can be taken in consideration, while in cases diagnosed after a longer period of time, a surgical approach should be taken into consideration. Meanwhile, although a surgical approach can cure most of the cases, attention should be given towards preventive strategies such as provision of quality obstetric care with improvements of surgical skills.
