Martius Flap Procedure to Repair Obstetric Fistulas

The Martius flap procedure is a surgical procedure used to treat obstetric fistulas in women. Heinrich Martius developed the procedure in twentieth century Germany to treat women with urinary incontinence caused by stress, and later doctors used it to repair obstetric fistulas. Fistulas occur in pregnant women when a hole is torn between the vagina and the urinary tract (called vesicovaginal) or the vagina and the rectum (called rectovaginal). The hole, or fistula, occurs in the tissue separating two organs and therefore obstetric fistulas result in either urinary or fecal incontinence. Fistulas can occur due to surgery, injury, or chemotherapy, but they most commonly occur in pregnant women who experience prolonged labor and do not have adequate access to obstetric care. As a result of the Martius flap procedure, patients regain functional use of their vaginas without continued urinary or fecal incontinence.
