A 9-year-old female dog was referred to Azabu University Veterinary Teaching Hospital for dysuria and dyschezia after ovariohysterectomy. After a series of diagnostic imaging, vaginal obstruction was suspected by vaginal fluid retention. Surgical repair was attempted three times to establish patency through the vagina and the vestibule by episiotomy and laparotomy. Another laparotomy was perfor...

Here we describe a case of pyometra coexisting with gestation in a 4.5 year-old miniature short-haired Dachshund. The dog exhibited depression, vaginal discharge, polydipsia and dehydration. Ultrasound examination revealed the presence of low to moderate anechoic fluid collection in the left uterine horn. Blood analysis revealed mild neutrophilia with a left shift. Based on these findings a pre...

This paper describes an approach to study the cells present in the subinvolution of placental sites (SIPS), a pathological post partum condition of the bitch that causes persistent hemorrhage of the genital tract. The expression of intermediate filament proteins was examined to determine the fetal or maternal origin of the cytotrophoblastic-like cells found in this entity. Lectin binding on tis...

To increase our understanding of the endocrine changes associated with parturition in dogs, plasma concentrations of progesterone (P4), 15-ketodihydroprostaglandin F(2alpha) (PGFM), estradiol-17-beta (E2beta), cortisol, ACTH, prolactin (PRL), LH, and FSH were measured in six spontaneously whelping bitches and in six bitches in which parturition was induced with the progesterone-receptor blocker...

Cystic endometrial hyperplasia-pyometra complex, by definition, is the accumulation of purulent material within the uterine lumen of intact bitches, typically occurring during or immediately following a period of progesterone dominance (1, 2). Pyometra is a common disease of adult intact female dogs (3). The mean age of diagnosis is 6-8 years, with a range of 4 to 18 years (4). Ageand breed-rel...

El síndrome de ovario remanente es una complicación conocida y de larga duración de la ovariectomía u ovariohisterectomía, que es causada por la presencia de tejido ovárico activo a pesar de una cirugía electiva. Como resultado de dejar restos de tejido ovárico en el abdomen o debido a la presencia de tejido ovárico ectópico, se desarrollan signos clínicos típicos de proestro o estro tales como...
