会陰部からの排膿を契機に診断された尿管異所開口の1例

Abstract

The patient was a 53-year-old woman with chief complaints of repeated pyrexia and pus discharge from the perineal region. A macroscopic examination revealed the presence of a fistula in the anterior wall of the vagina ; magnetic resonance imaging, retrograde urography through the fistula, and excretory urography indicated that the fistula was a complete left ureteral duplication with an opening on the anterior wall of the vagina. Laparoscopic ureterectomy of the left ectopic ureter was performed to achieve a complete cure. The ectopic ureteral opening led to a blind canal in the superior pole of the kidney. No postoperative complications were observed, and the symptoms disappeared. This is a rare case in which the patient, who did not have any symptoms until she became an adult, was diagnosed as having left ureteral duplication with the opening on the anterior wall of the vagina when pus was drained from the perineal region.
