[Thirteen cases of female urethral diverticula].

We report 13 cases of female urethral diverticula which were diagnosed at the Mishina Urological Office between July, 1984 and June, 1987. The 8 cases among them were discovered between July, 1986 and June, 1987 in the office, because the positive pressure urethrography has been energetically performed to detect female urethral diverticulum since November, 1985. The number of female outpatients in this period was 285, and the occurrence rate of the female urethral diverticula was 2.8%. Transvaginal diverticulectomy was performed in 5 of the 13 cases, using methylene blue-coagulum as an adjunct to the surgery. Postoperative course was uneventful in all cases. We herein reviewed the literature on this disease in addition to 65 cases including our cases since 1980.
