The present study was undertaken to investigate to what extent pregnancy diagnoses made by transrectal ultrasonography could be confirmed by measurements of plasma concentration of ovine pregnancy-associated glycoproteins (ovPAG). A total of 424 Awassi x Merino ewes were synchronized for estrus and examined by transrectal ultrasonography. In Experiment 1, the ewes (n = 156) were repeatedly scan...

The first application of ultrasound in medical diagnosis occurred in 1942 when Karl Dussik placed transducers on patients’ craniums and recorded the throughtransmission of the sound beam in an attempt to localize a brain tumor.1 In 1949, the first successful pulse echo system, which could record echoes from tissue interfaces, was developed by Douglas Howry and W. Roderic Bliss at the University...

Perirectal abscesses have only rarely been reported in horses. This case series describes the clinical signs, diagnosis, treatment and outcome of six horses with this condition. The equids affected were geldings or stallions various breeds aged from 4 months to 21 years (median age 10 months). Typical signs included colic tachycardia, tenesmus, dyschezia abdominal distension. diagnosis was obta...

A 43-year-old, otherwise healthy man had increasing abdominal pain in the lower abdomen without a fever. His leukocyte count was 20.0×109/L (normal range: 4– 9×109/L) and the C-reactive protein level was 155.5mg/L (normal <5mg/L). Abdominal computed tomography (CT) confirmed the suspected diagnosis of diverticulitis and revealed a large pelvic abscess (●" Fig.1). The intended CT-guided drainage...

Transrectal ultrasonography of the caudal uterus and a progestin profile were evaluated for accuracy in identifying mares with feto-placental compromise in a model of placentitis. Twenty-two pregnant ponies were divided into four groups: (1) control mares (n=5); (2) instrumented controls (n=2); (3) instrumented inoculated mares (n=11); (4) inoculated mares (n=4). Mares in Groups 3 and 4 were in...

OBJECTIVE The purpose of this prospective study was to evaluate the incidence of distal ejaculatory system defects with transrectal ultrasonography (TRUS) among patients evaluated for azoospermia. METHODS Forty-two patients with low-volume ejaculate and azoospermia were evaluated by physical examination, serum follicle-stimulating hormone and luteinizing hormone level determination, karyotypi...

The goal of the present study was to establish the possibility for determining the foetal sex in buffaloes through a single sonographic examination. The experiment included 39 female Bulgarian Murrah buffaloes raised and fed uniformly, inseminated by natural mating during the oestrus period. All animals were subjected to ultrasonographic examinations for pregnancy via transrectal approach. The ...

PURPOSE The purpose of this study was to analyze the detection rate of prostate cancers from targeted biopsy specimens of midline focal lesions and to investigate the ultrasonographic findings to reduce unnecessary additional targeted biopsies. METHODS Ninety-eight men with midline focal lesions detected on transrectal ultrasonography were enrolled. Additional targeted biopsies for midline fo...

CONTEXT: Prostatic cysts are uncommon. These cysts are usually asymptomatic and are diagnosed incidentally during ultrasonographic examination. On rare occasions, they may cause drastic symptoms. CASE REPORT: We report on a case of severely symptomatic anteriorly located prostatic cyst arising from the bladder neck in a 30-year-old man presenting with lower urinary tract symptoms, without cli...
