[Rare forms of ureteral fistulae occurring after obstetrical and gynecological operations].

In missed intraoperative injury to the ureter one can regularly observe retroperitoneal urinary overflow (urinary retroperitonitis). In case of postoperative ignorance of the injury the overflown urine penetrates into the vagina with formation of the ureterovaginal fistula. Less frequent there are ureterocutaneous or ureteroperitoneal, ureterointestinal fistulas after the urine breaking into the operative wound, abdominal cavity or the intestine, respectively. A case of a 37-year-old woman is reported with accidental injury to the left ureter overlooked during and after the operation. The patient developed successive ureteroperitoneal, ureterocutaneous and ureterosigmoid fistulas for which she has undergone 4 operations. After the recovery the function of the left kidney was retained.
