[Recurrent vaginitis and cystitis due to a vagina and cervix duplex in a bitch - a case report].

Incomplete merging of the Müllerian ducts may result in vaginal septa or even completely separate vaginal canals. It may also cause cervical malformation. In most cases, there are only rudimentary vaginal septations. Only a few reports describing completely separated vaginal canals (vagina duplex) and a cervix duplex in dogs have been published. This article reports the case of a bitch presented with recurrent vaginitis and cystitis. The symptoms always appeared following the dog's heat. The bitch had been pre-treated by a prior veterinarian as well as in a prior clinic. When presented in the clinic, a vaginal septum was suspected based on digital vaginal examination. Ultrasonographic examination and urinalysis allowed for the diagnosis of bacterial cystitis, which was subsequently treated with antibiotics. The bitch was presented again for vaginal endoscopy, transection of the vaginal septum, and ovariohysterectomy. Both vagina duplex and cervix duplex were diagnosed. Due to the extensive dimensions of the findings, the altered tissue was not resected. No more bacteria were detected in a repeated urine analysis. After spaying, the bitch showed no recurrence of symptoms of cystitis or vaginitis.
