Unilateral single vaginal ectopic ureter with ipsilateral hypoplastic and degenerated kidney associated with infertility in iberian ibex (capra pyrenaica) does

Abstract

This article describes the urinogenital condition of three female Iberian ibexes (Capra pyrenaica—one infertile 3-yr-old adult and two prepubertal animals aged 1 (PP1) and 2 (PP2) yr, respectively, all raised in captivity. All showed constant urinal dribbling, leading to ulcerative dermatitis in the vulvar area. Housed in a stable with other females, the adult did not become pregnant after male contact in either of two consecutive mating seasons. Vaginoscopy and laparoscopic exploration performed on the prepubertal females revealed abnormalities of the vagina and urinary bladder. Ultrasound examination revealed atrophy of the left kidney in the adult female and PP1, and of the right kidney in PP2, with degeneration of the renal pelvis. A paraovarian cyst with hydrosalpinx was also detected in the left oviduct of the adult female. Postmortem analysis of the adult and PP2, which shared amother, confirmed an extramural single ectopic ureter with vaginal insertion associated with atrophy of the ipsilateral kidney. Though PP1 was officially unrelated to the latter animals, all three might have had a common ancestor in their lineages.
