A 30-year-old patient, has not been conceived for fifteen years, was evaluating for infertility via hysterosalpingography. In the course of examination after inserting the canulla to the external cervical ostium, medium performed gently through cervical canal. Cervical canal, uterine cavity and bilaterally fallopian tubes distended by medium, respectively. Contrast medium poured onto peritoneum and as soon as pouring, suddenly, ascended bilaterally and synchoronously, enlarged and branched at the level of second lumbal vertebral silhuette which is indicating the kidneys. Bilateral linear, thin and sharp contoured images were ureters. We reported this unusual case whom intravenous-pyelogram, magnetic resonance imaging and intraoperative findings were inefficient for explaining of this retrograde passage of medium.
