[PMID: 37679951 PMCID: PMC10650372 DOI: 10.1002/vms3.1232] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/11/2023] [Revised: 06/30/2023] [Accepted: 07/21/2023] [Indexed: 09/09/2023] Open
Abstract
Vaginoscopy allows an intravaginal endoscopic evaluation and can help in the diagnosis of female bovine genital tract disorders. The aim of this study is to validate a new method of gynaecological examination using a Scope VOR&GDI videovaginoscope. Twenty-six heifers were used, divided into 2 groups with 13 animals, control group (GC) and videovaginoscopic group (GV). In the CG, vaginoscopy was performed with a vaginal speculum and in the GV with a Scope VOR&GDI videovaginoscope. All heifers underwent vaginoscopy on day 0 (D0), and 9 days later, on day 9 (D9). Vaginoscopy provided adequate intravaginal inspection. In the CG, 23% (3/13) of the heifers showed discomfort during the test. In GV, vaginal inspection was better due to better image quality. The videovaginoscope is the most effective equipment for carrying out the vaginoscopy procedure in Nellore heifers, as it produces sharper and clearer images and can help in the diagnostic and therapeutic routine of veterinarians.

Abstract
CONTEXT An accurate staging of sexual cycle is essential for the optimum timing of medical interventions. AIMS Here, an updated insight into clinical, endocrinological and vagino-cytological parameters, and their correlation with histomorphology of ovarian and uterine tissue samples is presented. METHODS Samples from 39 dogs were collected at various stages of the oestrous cycle: pro-oestrus (n =8), oestrus (n =12), dioestrus (n =9) (luteal phase) and anoestrus (n =10), according to clinical observations. Final allocation of samples was done after histomorphological evaluation of all tissues. Peripheral oestradiol-17ß (E2) and progesterone (P4) concentrations were measured, P4 by both chemiluminescent immunoassay (CLIA) and radioimmunoassay (RIA). KEY RESULTS Differences were observed between determination of the stage of the oestrous cycle, either by clinical, endocrinological or histomorphological evaluation. Individuals considered to be in clinical and endocrinological oestrus, had entered the luteal phase according to histomorphology. P4 concentrations measured by two different assays differed, underlying the importance to understand that absolute P4 concentrations may deviate depending on the used assay. Comparison of E2 and P4 concentrations is suggested to be useful when defining the transition from early follicular phase to the time of ovulation. CONCLUSIONS AND IMPLICATIONS Based on parallel histomorphological observations, combined with clinical and endocrinological findings on the same individuals, the present study emphasises that an accurate classification of the stage of the cycle in female dogs based solely on clinical and endocrinological assessments can be difficult. The histomorphological findings presented herein provide new insights into the transitional phases between the different stages of the oestrous cycle in the dog.

High-definition ultrasonography in the evaluation of the reproductive tract of bitches during the follicular phase of the estrous cycle. Anim Reprod Sci 2021; 234:106870. [PMID: 34673364 DOI: 10.1016/j.anireprosci.2021.106870] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2021] [Revised: 10/08/2021] [Accepted: 10/09/2021] [Indexed: 01/19/2023]
Abstract
The aim was to sonographically evaluate the reproductive tract of bitches during the follicular phase of the estrous cycle using High Density (HD) ultrasonic techniques. Females (n = 8) were evaluated at five different times throughout the follicular phase, as determined by vaginal cytology and blood progesterone concentrations. Ultrasonic exams were performed using the ACUSON S2000/SIEMENS device utilizing a multifrequency HD transducer (5.5-18 MHz). Videos of the ovaries were obtained and recordings were evaluated using a DICOM viewer software for counting and measuring the ovarian structures, which were assigned to groups based on diameter in mm: G1: ≤ 1; G2: from 1.01 to 3.5; G3 from 3.51 to 5.5; G4: from 5.51 to 10. There was a greater uterine thickness with the progression of the follicular phase (P < 0.05). Six distinct regions were identified in the uterine wall. The ovarian dimensions increased (P < 0.05) as stage of the follicular phase advanced. There was fluid detected around the ovaries after ovulation. There was a characteristic fat tissue hyperechogenicity around the ovaries at all timepoints. There was a difference in the number of ovarian structures of each dimension group at each time there were assessments (P < 0.05). There was a difference in diameter of the largest ovarian structure and in average value of wall thickness at all timepoints when there were evaluations (P < 0.05). The HD ultrasonography technique provides for excellent image resolution, allowing for a more precise characterization of the bitch's reproductive structures and changes occurring during the follicular phase of the estrous cycle.

Abstract
A breeding soundness examination is a vital part of any breeding program. These examinations are not performed as frequently in the bitch as they are in the male dog. They allow clinicians to identify any problems at an early stage in a bitch's breeding career and to screen for any genetic abnormalities. A thorough physical examination and accurate history guide the choice of which diagnostics tests are most useful. Ultrasound, culture, cytology, and biopsies (surgical and nonsurgical techniques) are discussed. Knowing which stage of the cycle to perform these diagnostics yields the most information and increases the chance of a successful outcome.

Vaginoscopy in Ewes Utilizing a Laparoscopic Surgical Port Device. J Vet Med 2017; 2017:7404371. [PMID: 29138758 PMCID: PMC5613375 DOI: 10.1155/2017/7404371] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2017] [Revised: 07/26/2017] [Accepted: 08/09/2017] [Indexed: 11/17/2022] Open
Abstract
Vaginoscopy allows for diagnostic evaluation and treatment of the vaginal vault. A laparoscopic surgical port device and rigid telescope were utilized for serial vaginoscopy in 8 healthy anesthetized ewes. Vaginoscopy examinations were performed in each ewe at days 1, 14, and 28. This technique was well-tolerated and facilitated carbon dioxide vaginal inflation, complete vaginal examination, identification of the cervix, and targeted biopsy collection. No complications were encountered during or following the vaginoscopy procedures. The laparoscopic port device was well-suited to the ewe vulvar size. This technique could be applied to clinical evaluation in ewes for the purposes of examination, biopsy, culture, foreign body removal, and minor surgical procedures.
