As it was urinating, a six‐month‐old Swiss braunvieh heifer produced a second stream of urine from a fistula that opened on the ventrolateral margin of the left vulval lip. A catheter was introduced into this opening and passed easily into the bladder. Urethrography showed that the fistula joined the urethra in the midpelvic region and that a single canal originated from the bladder. Endoscopy confirmed this finding and also revealed a duplication of the vaginal portion of the cervix, a division of the cranial vagina by a septum and a fibrous band in the region of the hymenal ring. Cytogenetic examination revealed reciprocal translocation between chromosomes 20q23 and 22q23. A diagnosis of urethra duplex, duplication of the vaginal portion of the cervix and reciprocal autosomal translocation between chromosomes 20 and 22 was made on the basis of these findings.
