Rare Case of the Utero-vesical Fistula Caused by Intrauterine Contraceptive Device

The vesico-uterine fistula is a very rare disease. There have only been 150-200 causes. We are reporting on a case in which the chronic fistula was caused by an IUD having been placed 4 years ago and it "wandered" through the bladder. A 30 year-old patient in 1992 and IUD was inserted. She had gynecological controls twice, in 1993 last time. She has problem of urination very often. A cyclical bladder bleeding drew the attention to the disease. In ambulanterely performed cystoscopy we found an IUD perforating towards the interior of bladder in the borderline of its bottom and back wall and was situated in the bladder with its 3/4. We have removed it with forceps. After six weeks of expectation and strict observation did we want to manage the fistula after having consolidated the symptoms of the inflamed surroundings. During the operation we have noticed a wallment size mass of scar between the uterus and the bladder expanding to the height of the orifice of the uterus. The scarily fixed bladder has been separated from the cervix and the scarry wall of the fistula has been cut out. We have brained the cervix towards the vagina and then we've sutured the cervix and the bladder with Dexon 'O' treat, as well. We have interposed a surgical net between the cervix and the bladder followed by blood-clotting and peritonisation. We should take the follows into consideration: careful separation, fine operative technique, and strong well absorbing thread as well as trying to keep the organ. In our opinion the bioplast--interpositum used on our case maker the efficiency of the operation higher.
