Abstract

Uterovesical fistulas belong to the least common types of urogenital fistulas. Although uncommon, they cannot be considered a rarity in view of about 800 published cases in the literature. They are most frequently caused by repeated caesarean sections, which are increasing, and their complications can be expected to increase as well. During the second caesarean section of a 31-year-old woman, the urinary bladder was opened and subsequently closed by a urologic surgeon. In the following weeks and months, the patient suffers from urinary incontinence in response to bladder filling, cyclic hematuria (menouria) and recurrent cystitis. After multiple examinations without establishing a diagnosis, an uterovesical fistula was suggested by cystoscopy and confirmed by cystography. The fistula, which measured 2 cm in diameter, was successfully closed by transperitoneal approach without interposition of omentum. Uterovesical fistulas are to be expected to increase due to an increasing rate of repeated caesarean sections. They can be suggested by their typical symptoms, easily diagnosed by imaging examinations and successfully treated by transperitoneal closure.
