RESUMEN
Uterovesical fistulas are the rarest of all urogenital fistulas, mostly occurring as a complication of cesarean section. We present a case of a 32-year-old woman, who noticed continuous vaginal urine leakage starting immediately after a vaginal delivery. The shortening of the uterine cervix was reported at 26th week of gestation, and a cervical pessary was placed. Shortly after delivery, the patient noticed the loss of urinary continence control, and she was diagnosed with urinary incontinence and hematuria. The office diagnostic hysteroscopy revealed uterovesical fistula. The correction procedure by transabdominal approach was performed by the team of gynecological and urological surgeons. One year of follow-up, the patient reports no symptoms related to lower urinary tract dysfunction. Based on the literature search, we believe that his is the first study of a uterovesical fistula followed by the use of a cervical pessary for the prevention of preterm delivery. Our case is a clear reminder that symptoms of urinary incontinence after vaginal delivery should be carefully managed.
